10、0 Executive SummaryEfficiency and productivity are two qualities that are increasingly establishing their dominance as keywords companies are using to market their products. The fact that their product can multitask or increase productivity better than the competition has become a real selling point

11、. This is due to the fact that effective time management is an essential factor in increasing production of day-to-day life. The best time management strategies involve being able to find time where there was no time before. Integration of technology into peoples daily lives has made that time manag

12、ement possible. The use of products such as tablets, PCs, and smartphones have given people access to the tools needed to be productive.However, though successful technological products have been used to increase productivity, it has done its fair share to stifle it as well. The use of technology ha

13、s become another task on everyones daily to-do list. Technology should mold to our schedule, not the other way around. That is where the smart mirror idea originated. The smart mirror idea aimed to integrate technology seamlessly into peoples lives by putting it where everyones routine eventually co

14、llides, the bathroom. The goal of the smart mirror is to increase a users productivity by saving them time. The smart mirror provides a near effortless experience that allows the user to just walk up and be greeted with information they would typically need another device for. Despite the fact this

15、information can be found on the users other devices, its the time-saving convenience of having this information available during the typical bathroom routines.The smart mirror has the necessary applications and features needed for time efficiency focused device. First, there is the easy on and off.

16、The mirror automatically recognizes that there is a user present and turns on the screen hidden behind the two-way mirror. A suit of six applications are presented on the 32” high-definition screen surrounded by a framed encasing that contains speakers and a webcam. These apps include weather, Twitt

17、er, news, to-do list, calendar, and music. The smart mirror application is run from a central computer with Windows 8.1 which features a multi-core CPU, solid-state memory, and wireless connectivity. The application can be interacted with by use of the Leap Motion controller. This controller allows

18、for touch-free control of the smart mirror by use of finger swipes, taps, and circles. There is also the option to use voice control to play music, post a tweet, or add a task to the to-do list. Finally, the mirror monitors its own temperature and humidity levels so that if the bathroom becomes pote

19、ntially harmful to the computers hardware, it can execute preventive measures and shut the system down.To develop a design of this size, significant research had to be done. First, similar projects and products had to be investigated to what has been done and possibly what needs to be done. Next, th

20、e individual pieces of the mirror had to research in order to decide on the best product to use in the smart mirror system. Some of these topics included the gesture control, voice recognition system, MCU, and hard drive type. Once the comparisons were made, each component was analyzed on how it wil

21、l function within the system and what it has to offer.1The design of the smart mirror was broken down into subsystems that represent important components of the project. Since there are hardware and software components to design, a block diagram was needed for both. The technical specifications were

22、 written for each subsystem for documentation and reference during the prototyping stage. The design contained charts, state-diagrams, and circuit designs regarding the details relating to what was prototyped. Once completed, the smart mirror delivered the experience of technology becoming part of a

23、 users routine and not an extra task.2.0 Project Description2.1 MotivationEffective time management is one of the most important factors for success and productivity in a persons day-to-day life. With the increasing integration of technology in our lives, maintaining an efficient schedule has become

24、 both easier and more difficult. Keeping up to date with appointments, Twitter, news, social media, and other things is made easier through technology such as tablets, PCs, and smartphones yet also provide distractions that can interrupt anyones routine. Technology has become another task in the day

25、 that time must be allotted for. In the finite time of the day, technology needs to be designed to work within our schedule and not be an extra piece to it.The key to effective time management involving technology is multitasking. Anyone in the business or academic world would agree that every secon

26、d counts in the day. This project was formulated through inspiration seen through movies such as Iron Man and tech demos, such as Samsungs transparent LCD Smart Window, seen at the International Consumer Electronics Show in 2012. This extends as well to the continuing trend of integrating touchscree

27、ns and internet-connectivity into everyday appliances such as ovens and refrigerators. The idea of a smart home is the direction lots of companies are heading and while the kitchen has been getting lots of attention, the bathroom has not. Besides the kitchen, the bathroom is one of the busiest rooms

28、 in the home, so it is an excellent place to expand the smart home next.Constant information and instant access to it drive the current generation. Forget bringing smartphones and tablets into the bathroom and risking damage. The smart mirror will show you that information with the swipe of a hand.

29、The smart mirror is the result of our team brainstorming on how to solve all these issues and develop something that is functional as well as a showpiece.2.2 Goals and ObjectivesThe smart mirror must offer benefits of using modern technology while integrating seamlessly into the standard bathroom ro

30、utines of most people. The smart mirror must be simple and as intuitive as possible. The smart mirror would be used to merge technology and the need for information into anyones daily schedule. With the mirror in place, the5user could interact and obtain the information they want during their normal

31、 morning and night bathroom routines.This smart mirror aims to reduce and possibly eliminate the need for the user to make time in their daily morning or nightly routine to check their PC, tablet, or smartphone for the information they need. The mirror will provide the information with little to no

32、effort from the user with the goal of not being a burden that he or she must maintain. The mirror wouldnt be another activity, rather an enhancement to the already common use of mirrors in most modern bathrooms.The mirror will do the thinking for the user. First, it will turn on and off by itself. T

33、hen, it will update with the users calendar schedule, to-do lists, Twitter, news, and weather. The information wouldnt be thrown in the users face, but unobtrusively displayed on the edges of the mirror to still allow use of the actual mirror. The use of touch-less gestures will keep things simple a

34、nd easy to use. No keyboards to try to keep dry and clean. The gestures will also allow the user to still use the mirror despite whether their hands are wet or dirty. The mirror provides common information most people check their smartphones or tablets for, such as weather, news, Twitter and schedul

35、es. This allows the users to read, think, and plan their day while getting ready in the morning or night. The mirror has to be fun as well. It will provide music playback that can be controlled by their voice so there is no need for a mouse or keyboard.Finally, the mirror must be smart enough to pro

36、tect itself from the wet and humid conditions that occur in every bathroom. It will feature a humidity protection system where it will monitor the temperature and humidity levels near the hardware. If the temperature or humidity levels are out of the safe operating range, then a failsafe system will

37、 notify the PC system so it can shut off to prevent damage.2.3 Requirements and SpecificationsThe smart mirror requirements and specifications took inspiration from peoples everyday devices that they use including PCs, tablets, and smartphones. The mirror integrated similar features from each to giv

38、e the user what they would expect out of a modern “smart” device. The following requirements and specifications were designed to satisfy the goals and objectives discussed in the previous documentation section.2.3.1 PC SpecificationsThe smart mirror was run through a central computer that took in th

39、e data from the various sensors and peripherals which in turn were used to provide the user with its key functionality. The general hardware specifications for this control computer are provided in Table 2.3.1.1 below.Motherboardmini ITX IntelRAM4GBCPUIntel i3Solid-State Drive64GBPower Supply380 wat

40、tWireless Adapter802.11b/g/nTable 2.3.1.1 PC Hardware Specifications2.3.2 Necessary FeaturesThe “necessary” features were requirements that are imperative to the projects design and objectives. They were designed and implemented before any additional features were worked on. The necessary features r

41、ange from hardware requirements to interactive elements and to software elements. These necessary features are listed below. The smart mirror is designed to use a 32” diagonal display, positioned vertically, which will mounted behind a one-way mirror allowing only elements lit on the screen to be se

42、en by the user. The smart mirror is interacted by the user through the use of an infrared/camera controller called “Leap Motion”. This controller allows for touch-free multi- gesture recognition within an 8 cubic feet area above the controller. The smart mirror has a temperature and humidity monitor

43、ing system that will relay data to the user as well as a failsafe system to keep the electronics protected from water damage. The ideal operating range is 60 to 90 degrees Fahrenheit and between 20 to 80 percent humidity. The smart mirror contains speakers that allow for application notification sou

44、nds and music playback. The smart mirror user interface has a set of 7 standard applications that provide important information to the user including weather, Twitter, news, to-do list, calendar schedule, music, and clock. The smart mirror has an auto-on and auto-off system via use of a webcam mount

45、ed in the housing. The mirror will turn on when it recognizes that there is a user standing in front of the mirror. The mirror will turn-off after 2-minutes of no user present. The smart mirror has voice control through a voice recognition system developed into the user interface. The voice control

46、allows for interaction with the music, to- do list, and twitter applications. The voice control is activated through a gesture provided by the user.2.3.3 Additional FeaturesThe “additional” features were requirements that are less imperative to the overall design and function of the project but woul

47、d add extra depth and usefulness to the smart mirror. These were to be designed only once all the necessary features were implemented and polished to a suitable working state. These additional features are listed below. The smart mirror would make use of the digital zoom built into the webcam to pro

48、vide more facial detail to the user on the display. This would be equivalent to a 10x zoom that could be used for putting on makeup or any other facial detail oriented task. The smart mirror would contain an outfit collection of the users favorite clothing combinations. The user would take a photo of themselves in the outfit via the webcam and it would be stored in a sud
