6. © Fraunhofer Portugal 2012 6 2. State Of The Art Technology ANT+  Wireless technology  Long battery life and high reliability  Over 60 Million installed nodes
7. © Fraunhofer Portugal 2012 7 2. State Of The Art Technology ANT+  Wireless technology  Long battery life and high reliability  Over 60 Million installed nodes Mobile and web  Android OS  Ruby On Rails
8. © Fraunhofer Portugal 2012 8 Scientific papers:  Little user research  Should be easy to use  Should have clear perceived benefits Research 2. State Of The Art
9. © Fraunhofer Portugal 2012 9 Scientific papers:  Little user research  Should be easy to use  Should have clear perceived benefits Informal interviews:  Similar systems currently being used are focused on real-time monitoring  Keep things simple  Give self-care and clinician feedback Research 2. State Of The Art
10. © Fraunhofer Portugal 2012 10  Low-fidelity prototypes  9 participants ≈ 71 years-old  The Method  Naming questionnaire  Tasks  Satisfaction survey  Common issues  Small fonts are very difficult to read  Complex words are bad idea  Instructions on the bottom of the screen were quickly forgotten 3. Developed Work Low-Fidelity Usability Tests
11. © Fraunhofer Portugal 2012 11 Mobile Application  Measure weight and blood pressure  Send measurements to physician  Send/Receive messages  View history  Receive measurement reminders 3. Developed Work Working Prototype
12. © Fraunhofer Portugal 2012 12 Web Application  Clinicians may select what patients to monitor  Send messages  View history  Schedule measurement’s alarm  Set threshold values for each patient’s device 3. Developed Work Working Prototype
13. © Fraunhofer Portugal 2012 13 Goals  Maximum possible realism  Test all use cases  Record from 3 different cameras  9 participants ≈ 67.8 years-old Method  Receive alarm and measure with each device  View clinician’s feedback message  Answer the clinician  View measurements history 3. Developed Work Final Usability Tests
14. © Fraunhofer Portugal 2012 14 Results:  Weight ≈ 3 minutes  Blood Pressure ≈ 4 minutes  First usage issues Feedback  Easy and useful system  One senior wanted to buy the mobile application  Some were conservative due to the cost of the devices 3.
