    1. 2. Over Arching Goal <ul><li>Come up with a portable aide to help elders conquer and learn new technologies. </li></ul>
    2. 3. In Particular… <ul><li>We are trying to reduce the confusion and discomfort elder’s face while using public computers . </li></ul><ul><li>Along with making the tasks easier for them, we also want them to learn the system. </li></ul>
    3. 4. Target Audience <ul><li>People who : </li></ul><ul><li>are over 65 years of age </li></ul><ul><li>access computers in public environments often. (Places usch as libraries) </li></ul><ul><li>may /may not have a personal computer or a laptop </li></ul><ul><li>only have basic knowledge about the technology </li></ul>
    4. 5. Proposed solutions <ul><li>From our research we have identified the most common tasks performed on a computer by our target audience : </li></ul><ul><li>Accessing email </li></ul><ul><li>Accessing / Viewing pictures </li></ul><ul><li>Playing simple games (for entertainment) </li></ul><ul><li>Other less common tasks : </li></ul><ul><li>Maintaining medical health records </li></ul><ul><li>Using video conferencing tools (like skype) to talk to friends/family </li></ul>
    5. 6. 3 Design Solutions
    6. 7. #1 <ul><li>USB device </li></ul><ul><li>Portable </li></ul><ul><li>All modern pc’s have usb ports </li></ul><ul><li>Plugging the device </li></ul><ul><li>What if the device gets lost? </li></ul>Pros: Cons:
    7. 8. #2 <ul><li>Portable device </li></ul><ul><li>Connectivity and security issues </li></ul><ul><li>Learning curve </li></ul><ul><li>Might be cumbersome to carry around </li></ul><ul><li>What if the device gets lost? </li></ul>Pros: Cons:
    8. 9. #3 <ul><li>Easiest to use in terms of portability </li></ul><ul><li>Requires no connection to public computer </li></ul><ul><li>Acts as a virtual assistant </li></ul><ul><li>Difficult implementation </li></ul><ul><li>Glare, heat from projector </li></ul>Pros: Cons:
    9. 10. Selected solution : #3 <ul><li>Device integrated into daily wear glasses </li></ul><ul><li>Consists of a camera and a projector </li></ul><ul><li>Detect screen state, and based on that, provide help options </li></ul><ul><li>Project highlights onto screen, so that user can immediately focus on desired object </li></ul><ul><li>Best supports our “learning” theme and is the most universal solution among the 3 (many possible combinations of email clients, browsers, operating systems) </li></ul>
    10. 11. Prototype
    11. 12. Prototype Details <ul><li>Prototype consists of : </li></ul><ul><li>Mockup glasses </li></ul><ul><li>Small projector </li></ul><ul><li>High fidelity slides </li></ul>“ Wizard of OZ technique”
    12. 13. Evaluation <ul><li>Things done: </li></ul><ul><li>Protype Evalution </li></ul><ul><li>User Questionnare </li></ul><ul><li>Heuristic Evluations </li></ul>
    13. 14. Prototype Evaluation & Questionare <ul><li>After the experiment : </li></ul><ul><li>Each participant was given a questionnaire. </li></ul><ul><li>This consisted of 5 likert-scale questions and 5 open ended questions. </li></ul><ul><li>During the experiment : </li></ul><ul><li>Observation and data gathering was done by note taking. </li></ul><ul><li>Along with the times and errors user’s reaction’s were also noted down. </li></ul>

    16. 17. Questionnaire Results A few results :
    17. 18. Questionnaire Results “ The (projector) glare was obtrusive” “ Finding the browser icon was easy” “ Makes navigating an unknown screen easier” <ul><li>Overall positive feedback </li></ul>“ I missed the instructions written at the top”
    18. 19. Heuristic Evaluations <ul><li>Heuristic evaluations done by 4 expert users. </li></ul><ul><li>10 heuristics used * </li></ul>` Source: Jakob Nielsen – www.useit.com/papers/heuristic/heuristic_list.html <ul><li>No error feedback. </li></ul><ul><li>No help documentation. </li></ul><ul><li>“ Go back” feature was not properly designed. </li></ul>Results:
    19. 20. Lessons learned <ul><li>Loading time skewed time records </li></ul><ul><li>We did not account for time delays that resulted from typing mistakes or typing ability </li></ul><ul><li>Our protype need to be more robust: </li></ul><ul><ul><li>our projection wasn’t contrasting enough </li></ul></ul><ul><ul><li>So user scenarios were unaccounted </li></ul></ul>
    20. 21. Future work <ul><li>Improve User Interface based on Protype Testing Results: </li></ul><ul><ul><li>Better navigation </li></ul></ul><ul><ul><li>Better documentation </li></ul></ul><ul><li>Conduct a more extensive user testing evaluation. </li></ul><ul><li>Explore mounting a projector on the user. </li></ul><ul><li>Explore image capture and processing. </li></ul><ul><li>Explore other projection surfaces. </li></ul>
