55 accessibility issues simulation for mobile applications

  1. 1. ACCESSIBILITY ISSUES SIMULATION FOR MOBILE APPLICATIONS Jan Vystrcil Czech Technical University in PragueCTU in Prague AEGIS Workshop and International Conference, Brussels
  2. 2. Computer vs mobile environment  Computer  Mobile  Keyboard,  Touch screen, mouse HW buttons  Large LCD monitor  Small display  Steady environment  Changing environment (indoors) (outdoor) - Artificial lightning - Sun, darkness - Fixed position - Movements - Planned activity - Frequent unpredictable interruption CTU in Prague AEGIS Workshop and International Conference, Brussels 2
  3. 3. Simulation of mobile environment in office?  More factors should be taken into account  Combination of factors also important  Difficult to simulate in office environment Hard to imagine Simulation desired CTU in Prague AEGIS Workshop and International Conference, Brussels 3
  4. 4. Mobile Impairment Simulation tool  Filter overlay window  Independent on mobile platform  Android  BlackBerry  iOS  Symbian  Windows 7  … CTU in Prague AEGIS Workshop and International Conference, Brussels 4
  5. 5. Categories of simulated issues  Visual impairment  Tunnel vision  Blurred vision  Color blindness  Occlusion of the display  Finger occlusion  Reflection on the display  Static reflections  Display tremor  Combined simulations CTU in Prague AEGIS Workshop and International Conference, Brussels 5
  6. 6. Visual impairment Blurred vision Tunnel vision Color blindness CTU in Prague AEGIS Workshop and International Conference, Brussels 6
  7. 7. Occlusion of the display Real world Simulation CTU in Prague AEGIS Workshop and International Conference, Brussels 7
  8. 8. Reflection on the display Real world Simulation CTU in Prague AEGIS Workshop and International Conference, Brussels 8
  9. 9. Future development  Planned effects  Macular degeneration  Dynamic reflections  Simulation scenarios  Ride on bus, walking, …  Combined impairments  Including parameter settings  Integrated help for each simulation effect CTU in Prague AEGIS Workshop and International Conference, Brussels 9
  10. 10. Conclusion  Platform independent simulation  Easy to use  Integrated help  Reference implementation  Version for Mac OSx  Beta version download https://cent.felk.cvut.cz/hci/accessible/index.php?page=mis CTU in Prague AEGIS Workshop and International Conference, Brussels 10
