中英文对照阅读--为什么手指永远取代不了鼠标
中英文对照阅读---为什么手指永远取代不了鼠标为什么手指永远取代不了鼠标体感技术不断发展之后，人们对体感控制器的期望越来越高。
但是，实测表明，这类产品目前还取代不了传统的鼠标，最近被寄予厚望的手势感应设备Leap Motion也不例外。
我中枪了。
我在桌子上朝空气又抓又砸又戳地比划了八秒钟，弗兰克•威尔提终于掏出手枪把我干掉了。
幸好这只是一场游戏，但是我却连一点取胜的机会都没有。
我的枪——在这场游戏中就是我的食指，一整天都没有击中任何东西。
这款射击游戏Fast Iron》只是最近上市的Leap Motion体感控制器的众多游戏应用里的一款。
Leap Motion是一种可以让用户通过手势控制电脑的外围设备.2012年5月，它刚刚发布的时候，的确带给人很多期待。
现在一年多过去了，这款79美元的设备也终于正式投放市场。
试用一周之后，以它目前的情况看，这种体感控制技术倒是说不出有什么问题。
安装Leap Motion体感控制器的过程出乎意料地简单。
我还以为必须得把这个体感控制器放在离屏幕一定距离的地方才行，要么就是必须得把这款设备放在一定的高度上，但事实证明这些都没必要。
而且也不必下载额外的软件，算是一款即插即玩型的设备，我通过一个USB接口就把它连接到了我的Mac上。
安装Leap Motion的软件也没什么难度，而且给人的感觉就是手势控制似乎很好掌握，似乎传感器可以很清楚地捕捉每个手指的运动。
但是软件的完善程度很不够，让我大跌眼镜——在我的Mac上运行的时候，它的全屏功能自行调节了所有其它应用窗口的大小，这一点非常讨厌。
而且图像也不太稳定，感觉就像分辨率很低一样。
想到这里，我心烦地摆了摆手，但是这款设备却没有探测到这个动作。
事后来看，这说明它灵敏度欠缺。
这个缺点可能会影响我对这款体感控制器的体验。
比如说，就在我选择能与这款设备兼容的软件的时候，我发现图像效果不佳反倒成了这款设备最小的问题。
这款设备有一个专门的Airspace Store 网络商城，主要销售各种第三方开发者针对这款设 He shot me. After a good eight seconds of flailing, grabbing, and poking at the air above my desk, Frank Welty finally unholstered his sidearm and put me out of my misery. Alas, it was only a game, but I never really stood a chance. My shooter, which in this case was my pointer finger, hadn't hit a damn thing all day.The game, Fast Iron, is just one of dozens of apps available for the newly launched Leap Motion Controller. A peripheral that lets users control their computer through hand gestures, this device showed plenty of promise when it was announced in May 2012. Now, more than a year later, the $79 product has come to market, and after a week of feeling it out, it's hard to point a finger at what exactly is wrong with gesture-based computing, at least in its current state.Setting up the Leap Motion Controller was unexpectedly easy. I had imagined having to input measurements like the controller's distance to the screen, or heeding requirements like keeping the device at a certain height, but none of that was necessary. Other than downloading a software suite, the peripheral was more-or-less plug-and-play, the unit powered and connected to my Mac via a USB cable.The Leap Motion software involved minimal hand-holding, and gave the impression that gesture-based controls would be easy to master, with the sensor seeming to pick up each finger and hand rotation cleanly. But the program's lack of finish caught my eye -- running on my Mac, the software's full-screen capability resized all my other applications windows (a huge annoyance), and its graphics looked choppy, almost like they were low-resolution. The device couldn't detect my hands shaking with worry over these concerns, but in hindsight, they were clear indicators of a lack of finish that would plague my experience with the controller.For example, as I continued pawing through the device's compatible software, poor graphics soon became the least of Leap Motion's problems.

科技能否促进创新英语作文
As a high school student, Ive always been fascinated by the intersection of technology and innovation. The rapid advancements in technology have not only transformed our daily lives but have also opened up new horizons for innovation. This essay aims to explore whether technology can indeed foster innovation and how it impacts our world.Growing up in the digital age, Ive witnessed firsthand how technology has revolutionized the way we communicate, learn, and work. The advent of smartphones, for instance, has made information accessible at our fingertips. Apps and software have transformed education, allowing us to learn new languages, explore different cultures, and even attend virtual classes. This ease of access to knowledge is a testament to how technology can stimulate creativity and innovation.One of the most compelling examples of technology driving innovation is in the field of artificial intelligence AI. AI has the potential to automate complex tasks, analyze vast amounts of data, and even make predictions based on patterns. This has led to breakthroughs in healthcare, where AI is used to diagnose diseases more accurately, and in the automotive industry, where selfdriving cars are becoming a reality. The ability of AI to learn and adapt makes it a powerful tool for innovation, as it can solve problems that were previously thought to be unsolvable.Moreover, the internet has been a gamechanger in the way we collaborate and share ideas. Platforms like GitHub and opensource projects have made it possible for developers from around the world to work together on software projects. This collective effort has led to the creation of innovativesolutions that address global challenges, such as climate change and poverty. The internet has democratized innovation, allowing anyone with an idea and the necessary skills to contribute to the development of new technologies.However, its important to acknowledge that technology alone is not enough to foster innovation. It requires a culture that encourages curiosity, risktaking, and the willingness to learn from failure. Schools and educational institutions play a crucial role in nurturing this culture by providing students with the tools and resources they need to explore their interests and develop their skills. By integrating technology into the curriculum, educators can inspire students to think creatively and solve problems in innovative ways.In addition to education, government policies and support for research and development also play a significant role in promoting innovation. By investing in technology and providing incentives for businesses to innovate, governments can create an environment where new ideas can flourish. For example, tax breaks for companies that invest in research and development can encourage them to take risks and explore new technologies.While technology has the potential to drive innovation, its also important to consider the ethical implications of its use. Issues such as privacy, data security, and the potential for job displacement due to automation need to be addressed. As we continue to develop and adopt new technologies, its crucial to ensure that they are used responsibly and for the benefit ofsociety as a whole.In conclusion, technology has a profound impact on innovation. It provides the tools and platforms necessary for individuals and organizations to explore new ideas and develop innovative solutions to complex problems. However, its the combination of technology, education, and supportive policies that truly fosters a culture of innovation. As a high school student, I am excited about the possibilities that technology offers and look forward to contributing to the innovative solutions of the future.。
自信来自于内在英语作文
Growing up, I often found myself in the shadow of others, comparing my abilities and achievements to those around me. It wasnt until I learned the true essence of confidence that I began to step out of the shadows and into the light. Confidence, as Ive come to understand, is not something that is bestowed upon us by external validation or achievements it is a deeprooted belief in our own abilities and worth.My journey towards selfassurance started with a simple yet profound realization: confidence comes from within. It was not the accolades or the praise from others that I needed to feel good about myself, but rather an internal acknowledgment of my own strengths and capabilities. This epiphany was sparked by a series of events that led me to question the source of my selfworth.In high school, I was part of the debate team, a place where I initially sought validation through the applause and recognition of my peers and teachers. However, one day, after a particularly challenging debate, I found myself questioning the sincerity of the praise I received. Was it the applause that made me feel confident, or was it my own belief in my argument and my ability to articulate it effectively? This introspection led me to the understanding that true confidence is selfgenerated.The turning point came when I faced a situation where external validation was not possible. I was preparing for a speech competition, and due to a sudden illness, I was unable to practice as much as I had hoped. The fear of failure loomed over me, but instead of seeking reassurance from others, I decided to rely on my own belief in my abilities. I spent the days leadingup to the competition reflecting on my past successes and reminding myself of the hard work I had put into preparing for the event.On the day of the competition, I stood on stage, my heart pounding in my chest. But instead of seeking the approval of the audience, I focused on the conviction in my voice and the power of my words. To my surprise, I delivered a speech that resonated deeply with the audience, earning me not just the first prize but, more importantly, a newfound sense of selfassurance.This experience taught me that confidence is not about seeking the approval of others it is about believing in oneself. It is about acknowledging our strengths, learning from our weaknesses, and trusting in our ability to overcome challenges. It is about embracing our unique qualities and using them to our advantage.Moreover, Ive come to recognize that confidence is a muscle that needs to be exercised regularly. It is not something that can be turned on and off at will. It is cultivated through consistent effort, selfreflection, and the courage to face our fears headon. Each time we step out of our comfort zone, we strengthen our confidence and reinforce our belief in our capabilities.In conclusion, confidence is an inner light that illuminates our path, guiding us through the darkest of times. It is not something that can be borrowed or bestowed it is something that must be nurtured and developed from within. As I continue to grow and evolve, I carry with methe knowledge that my confidence is not dependent on the opinions of others, but on my own selfbelief and determination. This understanding has not only empowered me but has also allowed me to inspire others to find their own inner strength and shine their light in the world.。

我的肢体语言的英语作文
我的肢体语言的英语作文Non-verbal communication is a powerful tool that can convey messages without uttering a single word. My body language, a significant part of this, often speaks volumes about my emotions and intentions.Growing up, I learned that a smile can break the ice and make people feel at ease. It's a universal sign of friendliness that transcends cultural barriers, and I often use it to express warmth and approachability.A firm handshake is another aspect of my body language that I've mastered. It's a gesture that exudes confidence and respect, and I make sure to use it when meeting new acquaintances or greeting friends.However, it's not just about positive gestures. I've also learned to control my body language when I'm nervous or anxious. Keeping my posture straight and maintaining eye contact helps me project calmness, even when I'm feeling anything but.In group settings, I've noticed the importance of active listening. Nodding in agreement or leaning in slightly when someone is speaking shows that I'm engaged and value what they have to say.Lastly, I've come to understand that body language canalso be a form of self-expression. Whether it's through a confident stride or an open posture, my body language often reflects my inner state and helps me connect with others on a deeper level.。
用两个事件来突出清洁工的品质英语作文
用两个事件来突出清洁工的品质英语作文全文共3篇示例，供读者参考篇1A Shining Example: Two Events That Showcased Our School Janitor's Wonderful QualitiesAs students, we often take for granted the hard work and dedication of the janitors who keep our school clean and functioning day in and day out. However, two particular events from my time at Oakwood High made me truly appreciate the outstanding qualities of our head janitor, Mr. Jonathan Wilkins.The first event occurred during my sophomore year when a severe storm hit our town. The high winds and torrential rains caused flooding throughout the school, leaving behind a mess of mud, debris, and soggy materials in many of the classrooms and hallways. When we arrived at school the next morning, we expected classes to be canceled while the cleanup unfolded. However, to our surprise, the entire building was spotless - you would have never known a storm had raged through just hours before.I later learned that Mr. Wilkins had worked through the entire night, leading a small team of janitors to ensure the school could open on time. They squeegeed water, mopped floors, dried out carpets, disposed of damaged items, and sanitized every surface. Mr. Wilkins's diligence, stamina, and commitment to his job allowed thousands of students to attend school that day without any disruption to their learning.What struck me most, however, was his humility when I thanked him personally. With a warm smile, he simply said, "Just doing my job, son. Keeping this place clean and safe for young minds like yours is what matters most." His modesty and care for the students' education over any personal accolades revealed his noble character.The second event that highlighted Mr. Wilkins's exceptional qualities occurred during my senior year. One afternoon, I was staying late to work on a group project when I heard a commotion coming from the cafeteria. Upon investigating, I discovered a young child, likely a sibling of a student, who had gotten separated from his family. The little boy was scared and in tears.Within moments, Mr. Wilkins appeared and deftly took control of the situation. He calmed the child, skillfullycommunicated with him despite the language barrier, and contacted the front office. However, it was what he did next that made my jaw drop. Mr. Wilkins brought the boy to his supply closet and let him pick out a few small toys from his personal collection to play with while they waited. He then sat with the child, entertaining him with a kaleidoscope of random stories and jokes that soon had the boy giggling despite his earlier distress.For over an hour, Mr. Wilkins simply focused all his attention on making this lost child feel safe, cared for, and happy. When the relieved parents finally arrived, they profusely thanked Mr. Wilkins for his kindness. With a sheepish grin, he waved off their gratitude, saying the smile on their son's face was thanks enough.As I watched Mr. Wilkins leave, clutching his mop and going about his duties, I marveled at his quiet display of immense compassion and heart. Here was a man whose job simply required him to clean, yet he exemplified human decency and grace in its highest form.These two events merely provided a glimpse into the outstanding qualities that made Mr. Wilkins such an exemplaryjanitor and human being. His work ethic, selflessness, humility, warmth, and care for others were unparalleled.Merriam-Webster defines a janitor as "a person employed to clean and maintain a building." However, the term hardly does justice to someone like Mr. Wilkins. He was a guardian of young minds, creating an environment where students could learn and grow. He was a protector of smiles, ensuring our school felt like a safe, welcoming place. He was the shining example of human kindness in its simplest yet profoundest form.Janitors like Mr. Wilkins are unsung heroes who demonstrate that no job is too small or insignificant to have a positive impact. His selfless deeds, despite the modest nature of his occupation, revealed a true leader deserving of our highest esteem and gratitude.As I look back on my years at Oakwood High, Mr. Wilkins will forever remain one of the most impactful figures I encoun篇2A Spotless Example: The Unsung Heroes Among UsAs students, we often take for granted the pristine condition of our classrooms, hallways, and campus grounds. However, behind the scenes, there are unsung heroes who work tirelesslyto ensure our learning environment remains clean, safe, and welcoming. These individuals are the janitors – the custodians of cleanliness who embody qualities that deserve our utmost respect and admiration. Through two remarkable events, I witnessed firsthand the dedication, compassion, and professionalism that define the best of these silent guardians.The First Event: A Lesson in Humility and Hard WorkIt was a typical Monday morning, and the weekend's revelry had left its mark on our school's cafeteria. As I entered the space, I was greeted by a scene that would make even the most seasoned custodian cringe. Tables were littered with crumpled napkins, spilled drinks, and half-eaten meals, creating a veritable minefield of mess.Amidst the chaos, a lone figure stood resolute – Mr. Johnson, our school's head janitor. With a determined expression and a mop in hand, he surveyed the area, seemingly unfazed by the daunting task ahead. As I watched in awe, he methodically began his work, tackling each table with unwavering focus and attention to detail.What struck me most was not just his efficiency, but his humility. Despite the thankless nature of his job, Mr. Johnson carried himself with a quiet dignity that commanded respect. Hemoved from table to table, meticulously cleaning every surface, leaving no crumb or stain behind.As the hours passed, the once chaotic cafeteria slowly transformed into a pristine oasis of cleanliness. Mr. Johnson's tireless efforts were a testament to his unwavering dedication and commitment to his craft. In that moment, I realized that true greatness often resides in the most unassuming of places, and that the janitor's role is not one of mere maintenance, but of creating an environment conducive to learning and growth.The Second Event: A Compassionate Heart Beneath the CoverallsSeveral months later, I found myself in the school library, buried beneath a mountain of books and research materials. As the hours ticked by, my focus waned, and fatigue began to set in. It was then that I noticed a familiar figure quietly entering the room – Mrs. Rodriguez, another member of our janitorial team.Rather than immediately launching into her duties, Mrs. Rodriguez approached me with a warm smile and a gentle concern in her eyes. She inquired about my well-being, offering words of encouragement and support. In that brief interaction, I felt a genuine sense of care that transcended her role as a custodian.As she began her work, I watched in amazement as she meticulously cleaned each surface, ensuring that the library remained a sanctuary of knowledge and tranquility. Her movements were methodical, yet infused with a tenderness that belied her strength of character.It was then that I realized the true depth of Mrs. Rodriguez's compassion. She not only tended to the physical cleanliness of our surroundings but also aimed to create an environment that nurtured the mind and spirit. Her kindness and concern for the students were as much a part of her job as the tasks she performed.In that moment, I understood that the janitor's role extended far beyond mere maintenance – it was a calling that demanded both physical and emotional fortitude. Mrs. Rodriguez embodied the qualities of empathy, understanding, and a genuine desire to support the academic and personal growth of those around her.Reflections on the Unsung HeroesAs I reflect on these two events, I am reminded of the profound impact that janitors have on our educational experiences. Their dedication to maintaining a clean and welcoming environment is not just a practical necessity, but atestament to their commitment to fostering an atmosphere conducive to learning and personal growth.Mr. Johnson's unwavering work ethic and humility taught me the value of perseverance and the importance of taking pride in one's work, no matter how seemingly insignificant it may appear. His example challenged me to approach my own studies and endeavors with the same level of focus and determination.Mrs. Rodriguez's compassion and nurturing spirit, on the other hand, reminded me of the power of kindness and the profound impact that a caring heart can have on those around us. Her gentle presence and genuine concern for my well-being showed me that true greatness lies not only in academic achievements but also in the ability to uplift and support others.In a world that often celebrates the extraordinary and the newsworthy, it is easy to overlook the quiet heroes who walk among us. Janitors like Mr. Johnson and Mrs. Rodriguez are living embodiments of the values that truly matter – hard work, humility, compassion, and a genuine commitment to creating a better world, one clean surface and one kind gesture at a time.As students, it is our responsibility to recognize and appreciate the invaluable contributions of these unsung heroes. Their tireless efforts create the foundation upon which oureducational journeys are built, and their unwavering dedication serves as a reminder that greatness can be found in the most unexpected places – even in the simple act of maintaining a clean and welcoming environment.So, the next time you enter a spotless classroom or walk through immaculate hallways, take a moment to appreciate the hard work and dedication of the janitors who make it all possible. For in their humble acts of service, we can find inspiration to strive for excellence, empathy, and a deep sense of purpose in our own lives.篇3A Shining Example: Two Events that Revealed the Remarkable Character of Our School JanitorAs students, we often take for granted the tireless efforts of those who work behind the scenes, ensuring our learning environments are clean and well-maintained. However, there have been two unforgettable events that shed light on the exceptional character of our school janitor, Mr. Johnson, and forever changed my perception of his role.The first event occurred during my freshman year when a fellow student, let's call him Tommy, suffered a ratherunfortunate incident. Tommy had a weak stomach and a tendency to get nauseous when overly anxious. One morning, as we were all settling into our seats for an important exam, the pressure must have gotten to him. Without warning, Tommy became violently ill, creating a truly unpleasant scene in the middle of our classroom.As you can imagine, the situation was utter chaos. Students scrambled to get away from the mess, while others simply sat in stunned silence, unsure of how to react. Our teacher, Mrs. Roberts, immediately sprang into action, ushering us out of the room and calling for assistance. Within minutes, the ever-reliable Mr. Johnson arrived, armed with his trusty mop, bucket, and an array of cleaning supplies.What struck me most was not just his efficiency in dealing with the situation, but his compassion towards Tommy. Rather than expressing frustration or annoyance, Mr. Johnson approached the distraught student with a gentle demeanor, reassuring him that accidents happen and that everything would be alright. He then proceeded to meticulously clean every inch of the affected area, ensuring not a single trace of the incident remained.But Mr. Johnson's kindness didn't stop there. After restoring the classroom to its pristine state, he took the time to check on Tommy, offering him a bottle of water and encouraging him to visit the nurse's office to rest and recover. In that moment, I realized that Mr. Johnson was far more than just a janitor; he was a beacon of empathy and understanding, someone who truly cared about the well-being of every student.The second event that left an indelible mark on me occurred during my junior year, when our school hosted a prestigious science fair. Students from all over the district had poured countless hours into their projects, meticulously crafting displays and experiments in hopes of impressing the judges and winning coveted prizes.As the day of the fair approached, excitement and anticipation filled the air. However, disaster struck when a severe thunderstorm swept through our area, causing a power outage that plunged the entire school into darkness. With the science fair just hours away, panic ensued as students scrambled to salvage their projects, many of which relied heavily on electricity.In the midst of this chaos, Mr. Johnson emerged as an unlikely hero. Despite the challenging circumstances, he remained calm and collected, quickly springing into action toensure the show could go on. With a team of dedicated custodians by his side, he worked tirelessly to set up emergency lighting throughout the exhibition halls, ensuring every project was properly illuminated.But Mr. Johnson's contributions didn't stop there. He also played a crucial role in securing backup generators, providing power to the most electricity-dependent projects. His quick thinking and problem-solving skills were instrumental in averting what could have been a complete disaster for the science fair.As the event unfolded, I couldn't help but marvel at Mr. Johnson's unwavering dedication and commitment to our school. Despite the immense pressure and unforeseen obstacles, he tackled every challenge with a positive attitude and an unwavering determination to ensure the success of the event.Through these two remarkable events, I came to understand that Mr. Johnson embodied qualities far beyond what one might expect from a janitor. His compassion, kindness, and dedication to his work were truly inspiring, serving as a shining example of what it means to be a valuable member of our school community.Mr. Johnson's actions taught me invaluable lessons about the importance of empathy, resilience, and going above andbeyond one's duties. He demonstrated that no job is too small or insignificant, and that every role, no matter how seemingly mundane, can be elevated through hard work, integrity, and a genuine concern for others.As I reflect on my time at this school, I realize that Mr. Johnson's impact extends far beyond the immaculate classrooms and hallways he maintained. His example has left an indelible mark on my character, reminding me to approach every task, no matter how daunting, with the same level of professionalism, compassion, and unwavering commitment he exhibited day in and day out.In a world that often overlooks and undervalues the contributions of those in service roles, Mr. Johnson stands as a shining beacon of what it truly means to be a dedicated and exemplary member of society. His actions have inspired me to approach life with a similar level of humility, kindness, and a willingness to go the extra mile, no matter the challenges that may arise.So, the next time you encounter a janitor, custodian, or any other individual working tirelessly behind the scenes, remember the remarkable example set by Mr. Johnson. Take a moment to appreciate their efforts and recognize the invaluable role theyplay in creating a better world for all of us. After all, true greatness often lies in the most unexpected places, and Mr. Johnson's story is a testament to the profound impact one person can have, simply by doing their job with unwavering dedication and a heart full of kindness.。
向某人寻求帮助的英文短语
向某人寻求帮助的英文短语Seeking help from others is a natural and often necessary part of life. Whether it's asking a friend for advice, requesting assistance from a coworker, or reaching out to a professional for guidance, there are numerous situations where seeking help can be beneficial. However, the way in which we approach and phrase these requests can greatly impact the outcome. The following essay will explore some common English phrases used when seeking help from others, and provide insights into how to effectively communicate these requests.One of the most straightforward ways to seek help is to directly ask for assistance. Phrases such as "Could you help me with..." or "I was wondering if you might be able to..." convey a polite and respectful tone, while clearly articulating the specific task or support needed. These types of requests acknowledge the other person's time and resources, and provide them with a clear understanding of how they can be of assistance. For example, "Could you help me proofread this report before I submit it?" or "I was wondering if you might be able to provide some feedback on my presentation slides."In addition to direct requests, it can also be helpful to express a need or challenge, and then ask for the other person's input or advice. Phrases like "I'm having trouble with..." or "I'm not sure how to approach this..." allow the person you're seeking help from to offer their expertise and perspective. This can be particularly useful when the problem or task at hand is complex or uncertain. For instance, "I'm having trouble understanding the new software program. Do you have any tips that might help me navigate it more effectively?" or "I'm not sure how to best handle this customer complaint. What would you suggest I do?"When seeking help, it's also important to be mindful of the other person's availability and workload. Phrases such as "If you have the time..." or "When you get a chance..." acknowledge that the person you're asking for help may have other priorities and commitments. This demonstrates consideration and can increase the likelihood of a positive response. For example, "If you have the time, I'd really appreciate it if you could help me brainstorm some ideas for the marketing campaign." or "When you get a chance, could you take a look at the budget spreadsheet and let me know if you see any discrepancies?"In some cases, it may be appropriate to offer something in return when seeking help, such as assistance with a future task or project. Phrases like "I'd be happy to help you with..." or "If there's anything Ican do for you in return..." convey a sense of reciprocity and can strengthen the relationship between the two parties. This can be particularly useful when asking for a significant amount of time or effort from the other person. For instance, "I'd be happy to help you prepare for your presentation next week if you have time to review this report for me." or "If there's anything I can do for you in return, please let me know."Finally, it's important to express gratitude and appreciation when someone does provide the requested help. Phrases such as "Thank you so much for your help" or "I really appreciate you taking the time to..." acknowledge the other person's efforts and can help to build stronger, more positive relationships. This can also encourage the person to be more willing to provide assistance in the future. For example, "Thank you so much for your help with proofreading the report. I really appreciate you taking the time to review it." or "I really appreciate you providing that feedback on my presentation slides. It was incredibly helpful."In conclusion, the way in which we seek help from others can greatly impact the outcome of the request. By using polite, considerate, and appreciative language, we can increase the likelihood of receiving the assistance we need, while also strengthening our relationships with those around us. Whether it's a direct request, a call for advice,or an offer of reciprocity, the phrases we use can make all the difference in how our requests are perceived and received.。
在演讲中如何使用肢体语言,英语作文
在演讲中如何使用肢体语言,英语作文Body language is an essential aspect of public speaking because it can enhance the delivery of your message and help captivate your audience. 身体语言是公开演讲中一个重要的方面，因为它可以增强你传达信息的能力，帮助吸引你的听众。
First and foremost, maintaining good posture is crucial when giving a speech. 首先，当你演讲时保持良好的姿势是至关重要的。
Standing or sitting up straight not only conveys confidence and authority, but it also allows for better breathing, which can help you project your voice more effectively. 直立或坐直不仅传达出自信和权威，而且还有助于更好地呼吸，这可以帮助你更有效地发声。
Gestures such as hand movements can also add emphasis to your words and make your speech more engaging. 手势，例如手部动作，还可以强调你的话语并使你的演讲更具吸引力。
However, it is important to use gestures sparingly and purposefully, as excessive or random movements can be distracting and detract from your message. 然而，重要的是要节制地和有目的地使用手势，因为过多或随意的动作会分散注意力，削弱你的信息传达效果。

ABSTRACT
This paper introduces the iGesture platform for investigating multimodal gesture based interactions in multimedia contexts. iGesture is a low-cost, extensible system that uses visual recognition of hand movements to support gesturebased input. Computer vision techniques support gesture based interactions that are lightweight, with minimal interaction constraints. The system enables gestures to be carried out ‘in the environment’ at a distance from the camera, enabling multimodal interaction in a naturalistic, transparent manner in a ubiquitous computing environment. The iGesture system can also be rapidly scripted to enable gesturebased input with a wide variety of applications. In this paper we present the technology behind the iGesture software, and a performance evaluation of the gesture recognition subsystem. We also present two exemplar multimedia application contexts which we are using to explore ambient gesture-based interactions.

iGesture was initially developed to investigate the use of ‘semaphoric’ gestures [6] in one’s environment to control multimedia applications, such as a digital jukebox [3]. Semaphoric gestures are those which represent signals or signs that can correspond to functional commands. To explore semaphoric, ambient gestures in more contexts, we extended the iGesture platform to support rapid deployment of gesture-based input for a broader range of applications. Primarily, the iGesture software performs a number of computer vision tasks in order to extract information from the visual scene to determine if gestures are being performed. The platform has been deliberately designed to work with a standard PC and single webcam. iGesture supports a number of loosely constrained single and two-handed gestures, such as waving. These gestures can be combined into a large command vocabulary. Significantly, these gestures can be readily detected at dynamically variable distances from the camera. This use of lightweight gestures with variable position interaction is in contrast to previous visual gesture recognition work which has required either close proximity of the gestures to the camera [1] or fixed proximity to the camera for application control [2]. By enabling these naturalistic, ‘in the environment’ gestures, iGesture provides a platform to explore ambient gestures within a ubiquitous, multimodal interaction space.

Figure 2: iGesture Video Processing Subsystem ambient gestures. First, we look at the use of ambient gestures for traditional interactions, such as functional control of desktop multimedia applications, thus extending the interaction from the desktop into the environment. Second, we look at ambient gestures for creative applications, such as their use as MIDI controllers for ambient orchestration. We conclude with a brief look at future work. motion vectors and marker positions into a state representation. In the current embodiment, there are 5 motion states per channel, and 4 position states which are shared across the two channels. The motion states represent whether the marker’s motion between the previous and current frame was upward, downward, left, right, or stationary. The position states represent the relative position of the two markers (if both are present) and are: marker 1 above marker 2, marker 2 above marker 1, markers approximately level, and markers really close together. From this set of states it is possible to model the motion of markers over a given number of frames as a Markov chain and determine a set of state-transition matrices that represent the chain. This set of state-transition matrices can be used to describe a semaphoric gesture. The construction of such a matrix is illustrated in Figure 3.
