  2. 1. MOTIVATION

  4. Why? ➔ simplification of one-handed interaction while taking pictures ➔ improvement of stability ➔ acceptance of usage?

  5. 2. RELATED WORK Air + Touch: Interweaving Touch & In-air Gestures Chen, Xiang „Anthony“/Schwarz, Julia/Harrison, Chris/Mankoff, Jennifer/Hudson, Scott E. (2014): Air+Touch: Interweaving Touch & In-air Gestures, in: Proceedings of the 27th Annual ACM Symposium on User Interface Software and Technology. New York, NY, USA: ACM, S.519–525

  7. 3. INTERACTION TECHNIQUES Left mouse click Right mouse press Defining Zoomcenter Panning the Picture

  8. Control Condition: Mouse Left mouse click on Left mouse press button Zoom in and out Release

  9. Interaction Scenario Mouth + Eyebrows Small mouth Wide mouth Raise Eyebrows Zoom in Zoom out Release

  10. Interaction Scenario Head + Mouth Tilt head forwards Tilt head backwards Open mouth wide Zoom in Zoom out Release

  11. 4. TECHNICAL REALIZATION/SETUP Laptop + Webcam + Mouse Face gestures

  12. 5. USER TEST 6 test persons 1 task for Mouth (zoom) + Head (zoom) + each scenario Mouse only Eyebrows (release) Mouth (release) = 3 tasks questionnaire

  13. Best-Case Picture amount of false pixels

  15. 6. RESULTS Mean: total time

  16. Mean: total error rate zoom Mean: total error rate release Mouse Mouth Head Mouse Eyebrow Mouth

  17. Mean: Efficiency percentage of correct pixels / total time in seconds

  18. One Significant Difference ➔ Total release error rate: Mouse interaction significantly more reliable than opening mouth for release p = 0,0483

  19. 7. QUESTIONNAIRE Most intuitive input Release function Raise eyebrows Open mouth Mouse click Zoom function Mouth wide & purse Head tilt Mouse Pan

  20. The most comfortable gestures Release function Raise eyebrows Open mouth Zoom function Mouth wide & purse Head tilt

  21. Gesture which would be used in public Release function Raise eyebrows Open mouth Zoom function Mouth wide & purse Head tilt

  22. 8. LIVE DEMONSTRATION

  23. 9. FURTHER RESEARCH ➔ Clutch mechanism ➔ Technical refinements ➔ Controlling pace of zoom

  24. Thank you!
