Two main options Outdoor Indoor Four sub options for each main option Some users may want more customization as well as more menus and options Enter more customization like contrast or white balance Flexibility and efficiency of use The system performs only one action magnifying which is fully automated Aesthetic and minimalist design Very simple system These glasses may be quite big because of the big battery Insert a smaller battery with less mAH without hi tech features or make the system more battery 47 efficiency Help error recovery In case of system crashing the user has to restart it The system should restart on its own There is no message that the system restarts so it will just turn off and on Enter messages that will pop when the system crashes and needs restart It may take a while in order to be ready for use again There must be an option of fast reboot in order to restart in half time Help and documentation The system is simple because of the touchpad and the interface Include a user s manual inside the package 48 Evaluation Personas Usage Older People David Roland e Scenario 1 Mr Roland goes for a trip to visit his brother He needs to take the train so he should book a ticket In order to do that he wears the glasses and uses the r

FarView This gadget magnifies text and it can be used in both real time point and view and click and save mode It allows the user to read text magnified In order to do that it uses a camera which is placed on the back Main Features e Store documents Document read mode The user can take pictures of a document and save them in order to watch them magnified after e Zoom in Distance viewing mode e Real time close up viewing A user can place it in front of a text and read it magnified in real time e Read Image enhancement e t uses a 7 5MP camera e The lowest magnifying rate is 2X while the highest is 42X e 4 3 inch colour TFT widescreen This is a nice approach with some advantages but with a lot of disadvantages Advantages e Big screen e High magnification rate Disadvantages Assuming the disadvantages this device is good only for using inside a building or when the user is on foot which is debatable because he she cannot see the environment Apart from this a lot of people want such devices in order to use them while driving This is definitely not appropriate for driving first of all the user has to hold the device and it does not show the Due to the fact it has a big screen it is a quite big device Users have to hold the device in order to read or watch The environment is not shown in the interface It is not suitable for driving The default magnifying level
4. Children Due to the bulk of the system and the fact that children are very active in their everyday tasks it is not the most suitable product to be used by them Using the system and inputting information will certainly not be a problem for children as most technology products are quite intuitive for them Think about it for a moment No one has to teach children how to operate a television a mobile phone or even a computer It is something that is everyday operations for them as they are surrounded by these devises ever since they were born This wasn t the case for older generations Persona Sarah Johnson Scenarios Evaluation e Everyday Activities No mode can help her in her everyday activities e Playing No mode can help her in her everyday activities e Doing homework Sarah need a device that magnifies everything around her as she needs to read and write Seminar mode is obviously not for her as she need to write in her textbooks Observations and Conclusions This device fails to cover any scenario related to Sarah and obviously is not appealing to her Young people visually challenged This category of users are most probable to be using the device with almost no problem Some may feel uncomfortable regarding the fact that information is shown close to their eyes Inputting information to the system will most certainly not be an issue for them This category of users probably know exactly what the system will be ca
5. Driving Mode The screen frame appears in a 50cm distance while the book it would probably be in a shorter distance System should be configured to calculate the distance and make the necessary changes to the screen frame To conclude we need a better system in terms of distance of the screen Reading mode cannot be fixed Because an essential part of the requirements the system should be configured 36 Prototype 2 People need to watch information about the objects situated in their environment These information can be displayed according to horizon So it will be easier for the user to watch these information and identify the objects because these information will not be displayed in front of their eyes Furthermore the display distance will not be fixed but it will be changed dynamically depending on the distance of the first object As a consequence users will have the ability to identify the distance of the object too g e USER OBJECT USER SCREEN 100m 37 OBJECT SCREEN ee USER 200m 38 FIRST POWER ON WELCOME SELECT YOUR VISION DIFFICULTY o MYOPIA o ASTIGMATISM o FARSHIGHTEDNESS o BLURRY VISION swipe the touchpad between the categories press to select and then press NE WELCOME SELECT THE LEVEL OF VISUAL DIFFICULTY RIGHT EYE Swipe the touchpad up to increase or down to decrease press to select and then press NEXT 39 WELCOME SELECT THE LEVEL OF VISUAL DIFFICULTY LEFT

He doesn t find it that difficult to use The remote control helped him a lot to navigate around the system He spent quite some time though to understand how to input his personal information He liked the fact that the system was working with modes Outdoors Indoors and then sub modes It helped him make the right choice Although he didn t quite understand the differences within the modes because there were no explanations Also the Other Mode confused him because it didn t do anything different than the walking mode 28 Through the modes Mr Roland took about 3 hours to feel comfortable around the system and get used to the screen and the features that the system provides Reading Mode amp Driving Mode got a really negative reaction from Mr Roland because he could see the book but the screen appeared a few centimeters behind the book and it was really confusing In Driving Mode Mr Roland was in the passenger s sit seeing an image in front of him while in the car was really distracting than helpful and to add to that it was distracting for the driver next to him as well Mr Roland enjoyed the use of Lecture Mode and Cinema Mode saying that it was really helpful and he could even read with ease the subtitles texts charts and slides Also he is fond of the Walking Mode because it provided him extra caution while in the park etc Children Due to the bulk of the system and the fact that children are very active in their everyday

13. tasks it is not the most suitable product to be used by them Generally using the system and inputting information will certainly not be a problem for children as most technology products are quite intuitive for them Persona Sarah Johnson Scenarios Evaluation e Everyday Activities Sarah didn t find a mode that suited her Walking and other mode for indoors just confused her because she could see only the things that were magnified e Playing Sarah use to the Running mode but still didn t made any difference Moreover glasses keep fall from her face e Doing homework Reading Mode didn t work out for Sarah because the image was behind of her books Observations and Conclusions Due to Sarah s visual impairment problem which is quite serious the glasses weren t able to solve the problem but it made some difference and helped Sarah Sarah took 7 hours to get used to the glasses but only because of her poor vision Nevertheless she had no problem finding her way through the system even entering her personal details etc Also she figured out that even though there aren t any buttons to select when she was done filling her information she just pressed the OK central button on the glasses At that point she mentioned that the remote control wasn t useful to her and that she find it more easy to use the buttons on the glasses 29 Due to her young age she was pretty forward and told us that the Other mode was useless
