It's like having a personal assistant that helps you with all sorts of tasks, from turning on the lights to adjusting the temperature, and even keeping your home secure.One of the most amazing things about smart homes is the ability to control everything with just your voice or a simple touch on your smartphone or tablet. Imagine waking up in the morning and saying, "Hey, smart home, turn on the lights and start the coffee maker." Just like magic, the lights come on, andthe delicious aroma of freshly brewed coffee fills the air. How cool is that?But that's just the beginning. Smart homes also have intelligent thermostats that can automatically adjust the temperature based on your preferences and the weather outside.

My name is Emma, and I'm a 4th grader who loves learning about all the cool new technologies that are making our lives easier and more fun. Today, I want to tell you about some of the amazing intelligent home gadgets that are helping people live more comfortably and efficiently.First up, let's talk about smart speakers like Amazon Echo or Google Home. These nifty little devices can do so much more than just play music or tell you the weather forecast. With just a simple voice command, you can control all sorts of things in your home, like turning on the lights, adjusting the thermostat, or even ordering a pizza for dinner! Imagine how convenient it would be to say, "Alexa, turn on the living room lights," without having to get up from the couch. How cool is that?Another awesome gadget is the smart security camera. These cameras can be placed inside or outside your home, and they use advanced motion sensors and facial recognitiontechnology to keep an eye on things. If someone tries to break in or if there's any suspicious activity, the camera will send an alert to your smartphone, and you can even see live video footage. Some of these cameras can even distinguish between people, pets, and other moving objects, so you won't get false alarms every time your dog walks by.Speaking of pets, there are now smart pet feeders and water dispensers that can make sure your furry friends are always well-fed and hydrated, even when you're not home. These devices can be programmed to dispense food and water at specific times, and some even have built-in cameras so you can check on your pets and even talk to them through the app!But wait, there's more! Have you heard of smart appliances? These are like regular kitchen appliances, but they're connected to the internet and can be controlled remotely using your smartphone or voice commands. For example, you can preheat your oven while you're still at school or work, so it's ready to go when you get home. Or you can check if you left the fridge door open while you're out running errands. Pretty nifty, right?Another cool gadget is the smart thermostat. These devices can learn your temperature preferences and adjust the heating and cooling in your home accordingly. Some even have sensorsthat can detect when you're home or away, so they can automatically adjust the temperature to save energy when no one's around. Plus, you can control the thermostat from your phone, so you can make sure your home is nice and cozy before you even walk through the door.Now, let's talk about something really fun: smart lighting! These are special light bulbs that can change colors, brightness levels, and even sync up with your music or movies. Imagine having a room that glows in different colors to match the mood of the movie you're watching or the music you're listening to. It's like having a little dance party in your living room!But smart home gadgets aren't just for fun and convenience – they can also help us be more energy-efficient and eco-friendly. For example, smart plugs can be used to turn off devices that are not in use, saving electricity and reducing your carbon footprint. And smart sprinkler systems can water your lawn or garden based on weather conditions and soil moisture levels, so you don't waste water.Overall, I think intelligent home gadgets are the coolest things ever! They make our lives so much easier and more fun, and they're only going to get better and more advanced as timegoes on. Who knows, maybe someday we'll have flying robot maids that can clean our rooms for us! A girl can dream, right?So, what do you think? Are you excited about all these cool gadgets, or do you prefer to keep things old-school? Either way, I hope you found this essay informative and entertaining. Happy gadget-ing!篇4Smart Home Tech: The Future is Here!Hi there! My name is Jamie and I'm 10 years old. I'm really into technology, especially all the cool new smart home gadgets that are coming out these days. My parents have been letting me learn about this stuff and I've become quite the little expert! I want to tell you all about the awesome intelligent home design products that are making our lives so much easier and more fun.Let's start with smart speakers like the Amazon Echo or Google Home. These little guys are voice controlled assistants that can do all sorts of amazing things. Just by talking to them, you can play music, set timers and alarms, get weather forecasts, control your smart home devices, and even ask random questions that the assistant will look up and answer for you. How cool is that? It's like having your own personal robot butler!Speaking of controlling things, smart lights and smart plugs are where it's at. With smart light bulbs, you can change the color and brightness just by asking or using an app on your phone or tablet. You can set them to slowly brighten in the morning to wake you up gently. Or make them pulse and change colors for fun at a dance party! Smart plugs let you turn lamps, heaters, fans or any plug-in device on and off remotely. My dad uses them to turn on the patio lights before he gets home from work.For home security, smart doorbells and security cameras give you a live video feed that you can watch from anywhere. If someone rings the doorbell or there's movement detected, you get an alert on your phone. Some even have two-way audio so you can tell solicitors to go away! You can also use smart locks to lock and unlock your doors from your phone. My parents use these to let me safely inside if I'm coming home before them.Another awesome thing is smart thermostats that learn your heating and cooling preferences. They automatically adjust the temperature when you're away to save energy. Then they make sure it's nice and comfy right before you usually get home. Talking about saving energy, smart power strips canautomatically cut power to devices that aren't in use, stopping them from wasting electricity on standby mode.For fun, you've got to check out smart displays like the Echo Show or Google Nest Hub. These combine a smart speaker with a touchscreen display. So not only can you ask it questions and have it respond out loud, but you can watch videos, see calendars and to-do lists, and even make video calls to your friends and family's smart displays. It's like having a little TV that you can control with your voice!Probably the coolest smart home devices in my opinion are robots like the robot vacuum cleaners and robot lawn mowers. You basically just press a button and these little guys will autonomously clean your whole house or mow your lawn for you! No more wasting your weekend doing those chores. The robot vacuums can even map your house and focus on high-traffic areas that get dirtier. I'm really hoping Santa brings me one this year so I don't have to vacuum my room anymore!There are so many other intelligent home products too like smart sprinkler systems, pet feeders and even appliances like washers and dryers that you can monitor and control from your phone. Basically anything you can imagine, there's probably a "smart" version that connects to the internet and lets you controlit remotely or set automated schedules. It's like living in the future!With all these gadgets talking to each other and working together, you can set up something called "routines" to control multiple devices at once with a single voice command or tap of a button. Like saying "Hey Google, good morning!" which could open the smart blinds, turn on the lights, read you the weather forecast, and even start brewing your coffee. Or an "I'm heading home" routine that adjusts the thermostat, turns on lights, and lets your robot vacuum know to start cleaning. It's super convenient!I hope I've gotten you as excited as I am about intelligent home design and all the incredible smart devices out there! We really are living in the future with this stuff. I can't wait to see what other mind-blowing technologies get invented in the smart home space in the coming years. Maybe we'll have entire smart homes that can do everything for us automatically! For now, I'm going to keep bugging my parents about getting me more of those cool robot cleaners. A kid can dream, right? Thanks for reading!篇5Intelligent Home Gadgets: The Future is Here!Hi there!

You may choose a paragraph more than once.Each paragraph is marked with a letter.Answer the questions by marking the corresponding letter on Answer Sheet2.Take Naps at Work.Apologize to No One[A]In the past two weeks I’ve taken three naps at work,a total of an hour or so of shut-eye while on the clock.And I have no shame or uncertainty about doing it.I couldn’t feel better about it,and my productivity reflects it,too.[B]Sleeping on the job is one of those workplace taboos-like leaving your desk for lunch or taking an afternoon walk-that we’re taught to look down on.If someone naps at2p.m.while the rest of us furiously write memos and respond to emails,surely it must mean they’re slacking off(偷懒).Or so the assumption goes.[C]Restfulness and recharging can take a back seat to the perception and appearance of productivity.It’s easier to stay on a virtual hamster(仓鼠)wheel of activity by immediately responding to every email than it is to measure aggregate productivity over a greater period of time.But a growing field of occupational and psychological research is building the case for restfulness in pursuit of greater productivity.[D]Companies are suffering from tremendous productivity problems because people are stressed out and not recovering from the workday,said Josh Bersin,Principal and Founder of Bersin by Deloitte.“They’re beginning to realize that this is their problem,and they can’t just say to people,‘Here’s a work-life balance course,go teach yourself how to manage your inbox,’”Mr.Bersin said.“It’s way more complicated than that.”[E]To be sure,the ability to nap at work is far from widespread,experts said.Few among us have the luxury of being able to step away for a half-hour snoozefest.But lunch hours and coffee breaks can be great times to duck out,and your increased productivity and alertness will be all the evidence you need to make your case to inquiring bosses.[F]In an ideal world,we’d all solve this problem by unplugging early and getting a good night’s sleep. Here’s our guide on how to do just that.But the next best thing is stealing away for a quick power nap when you’re dragging after lunch.[G]In a study published in Nature Neuroscience,researchers tested subjects on their perceptual performance four times throughout the day.Performance deteriorated with each test,but subjects who took a30-minute nap between tests stopped the deterioration in performance,and those who took a60-minute nap even reversed it.[H]“Naps had the same magnitude of benefits as full nights of sleep if they had a quality of nap.”said Sara Mednick,a co-author of the study and associate professor of psychology at the University of California,Riverside.[I]Dr.Mednick,a sleep researcher and the author of Take a Nap!Change Your Life,said daytime napping can have many of the benefits of overnight sleep,and different types of naps offer specific benefits.[J]For example,Dr.Mednick said a20-to60-minute nap might help with memorization and learning specific bits of information.It’s just long enough to enter stage-two sleep,or non-rapid eye movement(R.E.M.)sleep.[K]After60minutes,you start getting into R.E.M.sleep,most often associated with that deep,dreaming state we all enjoy at night R.E.M.sleep can improve creativity,perceptual processing and highly associativethinking,which allows you to make connections between disparate ideas,Dr.Mednick said.Beyond that,your best bet is a90-minute nap,which will give you a full sleep cycle.[L]Any nap,however,can help with alertness and perception and cut through the general fog that creeps in during the day,experts said.[M]So how did we even arrive at this point where aptitude is inextricably tied(紧密相连)to working long, concentrated hours?Blame technology,but think broader than smartphones and laptops;the real issue is that tech has enabled us to be available at all times.[N]“We went through a period where people were in denial and business leaders were ignoring it,”Mr. Bersin said.“They were assuming that if we give people more tools,more emails,more Slack,more chatter,and we’ll just assume they can figure out how to deal with it all.And I think they’ve woken up to the fact that this is a big problem,and it is affecting productivity,engagement,health,safety,wellness and all sorts of things.”[O]It isn’t just office workers who can benefit from an afternoon siesta(午睡).A2015study published in Current Biology looked at the at the sleeping habits of three hunter-gatherer preindustrial societies in Tanzania, Namibia and Bolivia.[P]“They’re active in the morning,then they get in the shade under the trees and have a sort of quiet time, but they’re not generally napping,”said Jerome Siegel,professor of psychiatry and biobehavioral sciences,and director of the U.C.L.A.Center for Sleep Research,a co-author of the study.“Then they do some work and go to sleep,and they sleep through the night.”[Q]Still,Mr.Siegel said,“the only genuine way to solve daytime sleepiness and fatigue starts the night before with a solid night’s sleep.”The real Holy Grail of restfulness is a regular sleep schedule with ideally seven or eight hours of sleep each night,which experts say is optimal.[R]“Daytime napping certainly does increase alertness,”Mr.Siegel said.“But it’s not as simple as going to the gas station and filling the tank.”[S]He also advises avoiding caffeine late in the day and waking around the same time every morning,even if you can’t get to sleep at the same time every night,This helps acclimate(使适应)your body to your regular wake-up time,regardless of how much sleep you got the night before.[T]So if you’ve made it this far and you’re interested in giving workday naps a try(or just starting to nod off),here’s a quick guide to the perfect nap;Find a quiet,unoccupied space where you won’t be disturbed.Try to make your area as dim as possible(or invest in a sleep mask you can keep in the office).Earplugs might help.too.Aim for around20minutes.Any longer than that and you’re likely to wake up with sleep inertia(睡眠惰性)，which will leave you even groggier(头脑昏沉的)than before.36.Participants’perceptual performance became better after sleeping one hour between tests in an article inNature Neuroscience.37.Jerome Siegel found that only by sleeping soundly through the previous night could people tackle theirweariness during the day.38.Our talent is closely bound to working with concentration for long periods of time because technologymakes us accessible24/7.39.Taking a nap at work is normally regarded as laziness that should be held in contempt and avoided inworkplace.40.Between20to60minutes,people can get into non-REM sleep which may improve memory and learningability according to Dr.Mednick.41.People can doze off at lunch and coffee breaks and defended themselves by saying their improvedproductivity and alertness when bosses investigated their whereabouts.42.The author’s tips on taking a perfect nap involve sleeping place,environment and duration.43.The author believes business leaders are aware that availability at any time due to technology has negativeeffects on every aspect of people’s life.44.The optimal length of a nap was an hour and a half so that people could go through a complete sleep cycle.45.Josh Bersin mentioned the cause of companies’big productivity problems and the solution which needsmore that just employees’efforts.Section CDirections:There are2passages in this section.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet2with a single line through the centre.Passage OneQuestions46to50are based on the following passage.Every office worker hates meetings.But it’s a strange sort of hate,similar to the hatred of Londoners for the Northern Line,or New Yorkers for tourists who walk too slowly:the dislike is real,yet if the despised thing were to vanish,it’d be like surrendering a piece of your soul.When researchers probed into why people put up with the strain that meetings place on their time and sanity, they found something-those who resent and dread meetings the moat also defend them as a“necessary evil”, sometimes with great passion.True,research suggests that meetings take up vastly more of the average manager’s time than they used to.True,done badly,they’re associated with lower levels of innovation and employee wellbeing(幸福).But that’s just office life,right?It’s not supposed to be fun.That’s why they call it work.Underlying(引起)this attitude is an assumption that’s drummed into us not just as workers but as children, parents and romantic partners;that more communication is always a good thing.So suggestions abound for(大量存在)communicating better in meetings-for example,hold them standing up,so speakers will come to the point more quickly.But even when some companies consider abolishing meetings entirely,the principle that more communication is better isn’t questioned.If anything,it’s reinforced when such firms introduce“flat”management structures,with bosses always available to everyone,plus plenty of electronic distraction.In fact,constant connectivity is disastrous for both job satisfaction and the bottom line.And anyway,once you give it three seconds’thought,isn’t it cleat that more communication frequently isn’t a good thing?Often,the difference between a successful marriage and a second-rate one consists of leaving about three or four things a day unsaid.At work,it’s surely many more than four,though for a different reason;office communication comes at the cost of precisely the kind of focus that’s essential to good work.Yet we’re so accustomed to seeing talking as a source of solutions-for resolving conflicts or finding new ideas-that it’s hard to see when it is the problem.46.What does the author say about meetings?A)Londoners hate them as well as the Northern Line.B)They can help to keep workers’physical and spiritual health.C)Workers might be reluctant to give up them completely.D)New Yorkers dislike meetings more than Londoners.47.What did researchers find about people’s attitude towards meeting?A.Their attitude and behavior are paradoxical.B)People who hate meetings the most are senior insane.C)Those who like meetings might be considered insane.D)More meetings are regarded as a sign of less innovation.48.Why do people think that more communication is always a good thing?A)Because the concept is firmly believed by workers.B)Because everyone loves to communicate with others.C)Because the idea has been instilled into people’s mind.D)Because communication is vital for building relationships.49.What does the author think of the“flat”management structure?A)It forces bosses to frequently contact their employees.B)It helps to soften employees’bottom line of work.C)It is definitely a disaster to employees’job satisfaction.D)It strengthens people’s deeply-rooted notion of communication.50.What is the author’s argument about office communication?A)It is an effective way to solve office conflicts.B)It affects work efficiency in a negative way.C)It should come to a halt at intervals.D)It is useful for workers to find new ideas.Passage TwoQuestions51to55are based on the following passage.The Internet has enabled the spread of information at lightning speed.This information revolution has created tremendous business opportunities for online publishers,but not all of them maintain proper quality-control mechanisms to ensure that only good information is being shared.Instead,many publishers aim simply to make money by whatever means possible,with no regard for the implications for society at large.When selfish publishers set up shops online,the primary goal is to publish as much as possible,often at the cost of quality.In this respect,many publishers start numerous online journals focused on overlapping(重叠的)disciplines—to increase their total number of published papers—and hire young business managers who do not have any experience in either science or publishing.In some cases,online publishers even give up peer review, while still presenting themselves as scientific journals—deception designed to take advantage of scientists who simply want to share their research.If publishers structure their business to make more revenue,it often does harm to their products.When publishers start journals with overlapping domains,in combination with the pressure to publish more studies,this could promote the publication of marginal or even questionable articles.Moreover,publishers with multiple overlapping journals and journals with very narrow specialties(专业)increase the demands on the time and efforts of willing reviewers.With the fact that reviewers are generally not compensated for their time and effort,journal editors are often unable to find enough reviewers to keep up with the increased publication rate.To improve the situation and increase the trust in scientific community,the pressure to publish must be reduced.Funding and promotion decisions should not be based on the number of publications,but on the quality of those publications and a researcher’s long-term productivity and instructions.And that’s just the start.We need additional mechanisms,such as Beall’s list of predatory(掠夺的)publishers, to alert scientists to fake journals and fake articles.In addition,the price for online publication must be controlled and a mechanism must be put in place to honor and reward hard-working reviewers.51.What does the author think of online publishers?A)A small proportion of them can guarantee their publishing quality.B)They have lots of opportunities to renovate their business models.C)Many of them tend to try every means to make a buck.D)Social impact is their first priority when publishing books.52.It can be inferred from the second paragraph that______.A)peer review generally is a criterion to identify academic journalsB)researchers focus their research on the combination of disciplinesC)scientists care about their publications rather than researchD)young business managers are willing to face new challenges53.Why can’t publishers find enough reviewers to review papers?A)Reviewers are pressed for time when reviewing articles.B)Reviewers’gains can’t make up for what they have done.C)Publishers may compel reviewers to accept marginal articles.D)Publishers urge reviewers to increase publication rate rapidly.54.What is the author’s suggestion for online publication?A)More weight should be put on the quantity of publications.B)It is worthwhile to reward diligent reviewers for their effort.C)Fake journals should be reported to a regulatory organization.D)The price of online publication should be lowered greatly.55.What is the main idea of this passage?A)Online publishers should take measures to fight against fake scientific journals.B)Online publishers are pursuing their work efficiency at the cost of quality.C)Online publishers business models are quite likely to harm their publications.D)Online publishers are sacrificing the quality of research articles to make money.PartⅣTranslation(30minutes)Directions:For this part,you are allowed30minutes to translate a passage from Chinese intoEnglish.You should write your answer on Answer Sheet2.春节是中国的传统节日，相当于美国的圣诞节。

Since they suffer great inconvenience to move their body even for simple task, it is necessary to develop a human-friendly residential system to serve daily-life such as reading a book/newspaper, eating a food, massaging and operating home appliances. For constructing a human-friendly residential system, we focus on the development of three detailed research parts: 1) intelligent bed robot, 2) soft remocon, 3) network.In this paper, we present each element and function of theses system and confirm their usefulness.1. IntroductionIn the society, each constituent would live his/her life with the blessed feeling of equality. In particular, it would be a society where the aged and elderly and even the disabled would live well independently and comfortably along with the ordinary normal people. Various types of high-tech equipment and systems may provide a good alternative for independent living of such people.The intelligent house for physically impaired people integrates devices for movement assistance of the resident and devices for continuously monitoring of his/her health status. Such solution will have strong positive emotional impact on the patients, improving their quality of life, giving them privacy and feeling that he/she lives in an ordinary house, not in a hospital. The same approach will reduce significantly the medical care costs per person. According to various sources, we may confirm that the importance of "smart houses" for the elderly and the disabled has been well understood. In several European countries, a number of demonstration smart houses for testing different strategies of the elderly and the disabled were developed. Here we may mention AID project (Assisted Interactive Dwelling) [1], Smart House project (developed at Social Housing SPRU - University of Sussex, UK), HS-ADEPT [2], HERMES, the Smart Home project (at Brandenburg Technical University, Cottbus, Germany), the Gloucester Smart House in UK (oriented to the specific needs of people with dementia), the SmartBo project [3], etc..In contrast to existing automated homes that can be programmed to perform preliminary defined functions, a team of the Colorado University [4] proposes the idea of the smart house where the home controller can essentially programs itself by observing the lifestyle and desires of the inhabitants and learning to anticipate their needs. Fifteen demonstration and research houses, known as Welfare Techno Houses, have been recently built across Japan. A life-support infrastructure environment, called "Robotic Room" was developed at the Sato Laboratory at the Research Center for Advanced Science and Technology in the University of Tokyo [5][6] in response to the needs of the rapidly aging society.Present paper comments some of the conceptions that were implemented in our sweet-home project LARES. Proposed organization of the smart house considers some recent technology innovations as well as some specifics in the lifestyle and traditions in Korea.2. Intelligent Sweet Home2.1 Overall SystemR&D of intelligent human-friendly residential system is urgently in demand to comply with the needs of human being to lead more convenient and safe lives and to deal with the increase in the number of the elderly and the handicapped.To this end, our work is focused on the development of three detailed research parts: 1) intelligent bed robot, 2) soft remocon, 3) network as shown in Figure 1..2.2 Intelligent Bed RobotAn intelligent bed system is developed to assist the elderly and the handicapped to live a convenient daily life since they usually spend much time in their beds. Figure 1 shows the prototype of the bed system consisting of three parts – automatic bed, robotic arm and motion capture system.The bed is designed in consideration of human body and can change its pose in various ways as shown in Figure 2. The upper part can be folded from 0 to 90 degrees and the folded curve is similarly formed as the curve from pelvis to waist of human body by adopting 4-bar mechanism. The lower part is folded from –70 to 70 degrees for the user to keep a comfortable pose.Figure 1. Overall System of Intelligent Sweet HomeFigure 2. Flow of Bed mechanism designFigure 3 shows MANUS arm attached at the side of the bed and utilized to serve transporting objects, pulling a quilt over, etc. As shown in Fig. 4, the robotic arm also has the large work range including a table, a bookshelf and a massage-hanger around the bed. The robotic arm can manipulate with pre-programmed path for service delivering a newspaper or a book because we assumed that the position of these was fixed.And it can use the motion capture system to feedback the position data of markers attached on the edge of a quilt in real time. Two markers are used to find the direction and the position for gripping a quilt. As you see figure 5, using coordinate transformation, the position of marker by motion capture system(Pr) is translated to the position by the end effecter of robotic arm(Pm).Because the scan range of motion capture system is including all ranges of the bed, we can obtain position information of anything on the bed, a pillow, a movement of the user, etc.Figure. 3Appearance of attached robotic armFigure. 4Range of Robotic arm and mocap systemBack LiftingFront LoweringBack LiftingFront Lifting Front Lowering(2.a)(2.b)(2.c) (2.d)Figure 5. Axis transformation of mocap dataThe intelligent bed robot with a proposed configuration is very useful to assist daily life of the elderly and the handicapped, and is able to serve four kinds of fundamental tasks: pulling a book and put it back on the bookshelf, transporting a newspaper, massaging, and pulling a quilt over and putting away it.2.3 Soft RemoconThe remote controller seems to be a good choice for the normal people, but it cannot be helpful for the handicapped/elderly since it happens that they cannot move themselves to find the controller nor remember where it is. Recognizing an object pointed by a finger and a successive hand gesture for commanding machines is an alternative way in the sense of human-friendliness since it is how human does.Figure 6. Soft remote control systemFigure 6 shows whole system configuration of soft remote control system.We have attached 3 cameras on the ceiling to capture the arm position as shown in figure 7. Though two cameras are enough to calculate the direction of the arm, one more camera is installed for the case when the arm occludes in the view of another camera. It is shown well in figure 8.Figure 7. Three cameras of soft remote control systemFigure 8. Three images from each cameraFigure 9 shows the signal processing procedure of soft remote control system.. The system has five modules: data acquisition module, preprocessing module, hand region segmentation module, pointing recognition module and appliance control module.The starting module of the system is data acquisition module. To acquire images from cameras, we use three cameras equipped with pan/tilt devices with 2 DOF (degree of freedom). After obtaining the images, the preprocessing module enhances the images and removes noise. In this module, skin color region including hand and face is detected.The next is hand region segmentation module. It selects hand region from skin color region. Since the output of this module needs to be converted into a suitable form, which means representation of raw data, for computerprocessing, the feature extraction processing is alsoincluded in this module. The next is pointing recognition module that calculates the orientation angle and pointing direction. The last is appliance control module in which the according IR signal is send for controlling home appliances.Figure 9. Signal processing procedure of soft remote control systemWe use several specific devices in this system such as pan/tilt devices, vision board and remote control board. Vision board is used in data acquisition module, preprocessing module and hand region segmentation module, and remote control board is used in appliance control module.To develop the soft remote control system, this paper considers three assumptions as follows:Assumption 1: Only one user is in the intelligent room. Assumption2: Three cameras capable of panning/tilting focus on the user.Assumption 3: The user points at an object by using his right arm and right hand.Currently, we are able to do on/off control for those several home appliances including TV, VCR, automatic door, light and curtain. Figure 10 shows the procedure of finding the arm area and the arm direction.Figure 10. Pointing Recognition2.4 NetworkThe intelligent sweet home consists of many assistive devices and sensors such as robotic arm, motion capture device, camera system and hand gesture recognition system. Since some devices are responded to the other devices, network connection is in demand to comply with sharing information each other and TCP/IP-based network configuration is established with home network server.3. Concluding RemarksIn this preliminary result of developing an intelligent sweet home, we have suggested and have implemented several components which help them have independent daily living. Further, according to evaluation by the handicapped, we have collected feedbacks which will be seriously considered for designing the next version of the systems. We believe that one of the biggest reforms to occur in residential space is to adopt various service robots to help the habitants in many ways.The idea of intelligent sweet home is treated at present not as a science fiction but as important goal with strong social and economics aspect. Its realization will give a solution of many existing problems of the welfare society and will make the handicapped/elderly's lives as well as human life much pleasant and easier.
