  1. GESTURES • Riley Wiebe • CMPT 479 • November 28, 2013

  2. GOALS • Generalize gestures in ISO/IEC CD 30113-2 • Simplify gestures • Points of interest • No program specific gestures • Create a more useable structure for developers

  3. WHO CAN USE THIS INFORMATION? • Developers • Typical uses for a gesture • Users • Expected gestures

  4. SOURCES OF INFORMATION • ISO/IEC CD 30113 (June 06, 2013) • Original documents • draft of new annex A framework for 30113-1 (Sept 30, 2013) • Proposed organization structure • ISO/WD 9241-960 (June 11, 2012) • Designing Gestures

  5. SOURCES OF INFORMATION • Apple’s iOS Human Interface Guide (Nov 22, 2013) • Actions vs Specific Directions • Android’s Gestures Guide (Oct 22, 2013) • Actions vs Specific Directions • Windows’ Touch Interactions Guide • Design Principles For Touch

  6. ASPECTS OF A GESTURE • Points of Interest • Single point, two point, multipoint • Actions • Tap, Drag, Swipe, Flick • Specific Directions • Up, Down, Left, Right • Result

  7. GENERALIZING GESTURES • Currently Gesture Set For • Mouse • Web Browser • Document Viewer • Image Viewer • Media Player

  8. GENERALIZING GESTURES • Similar gestures for similar applications • Left/Right • Up/Down • Left & Right/Right & Left • Up & Down/Down & Up • Up & Left/Up & Right/Down & Left/Down & Right • Left & Up/Left & Down/Right & Up/Right & Down

  9. GENERALIZING GESTURES • Are these separate gestures or composites? • Ex. Up & Left • Should these composite gestures be used? • Accuracy of the user to perform the gesture • Does it interfere with other gestures? • Ex. Scrolling and an up & left gesture

  10. POINTS OF INTEREST • Single Point • Tap, Drag, Swipe • Two Point • Pinch, Rotate, Swipe • Multi Point • Swipe, Pinch (OS X)

  11. PROPOSED ORGANIZATION TABLE

  12. COMPOSITE GESTURES • Not intuitive • Can confuse other gestures • Swipe up vs Swipe up & Left • What is the margin of error? • Are there better gestures for the job? • Double Tap, Pinch, Rotate

  13. LIMITING SWIPE GESTURES • Left • Right • Up • Down • Possibly Angles

  14. GROUPING COMMON SINGLE POINT GESTURES • Tap is a select • Press and hold for selecting • Drag for moving an item • Swipe • Left to go back • Right to go forward • Up to scrolls up • Down to scrolls down

  15. REPLACING COMPOSITE GESTURES WITH MULTI POINT • Pinch (Two Point) • Zoom in, Zoom out, Close, Open • Rotate (Two Point) • Swipe Up/Swipe Down • Increase/Decrease Volume

  16. GROUPING COMMON TWO POINT ACTIONS • Pinch is zoom in zoom out • Two finger rotate • Two finger swipe to switch tabs • Multi finger pinch

  17. SHOULD IT BE IMPLEMENTED AS A NEW GESTURE? • Maximize/Minimize • Close • Volume • Drag a Slider

  18. NEW ORGANIZATION TABLE

  19. NEW GESTURE LIST • Tap/Double Tap • Swipe (Left, Right, Up, Down) • Drag • Pinch • Rotate

  20. CONCLUSION AND RECOMMENDATIONS • Easier for Developers • Better user experience • User feedback • Ergonomics
