1. Navigating 3D Worlds via 2D Multi- Touch Interfaces Daniel Cope Supervised by Stuart Marshall 1

2. Motivation Multi-Touch hardware is becoming common place. Existing solutions do not provide all six degrees of freedom. Initial applications for use with the general public. 2

3. Project Problem Two main problem areas: o Interaction with a 2D touch surface o Navigation through a 3D space 3D navigation based on flight simulators and 3D modelling software. Criteria for gesture sets. o Intuitive, Robust, Simple, Scalable and Resistant. 3

4. Proposed Solutions Evaluate three gesture sets. Indirect gestures. o On screen joystick controls. Static gestures. o “Standard” gestures. Dynamic gestures. o Variation of static gestures. 4

11. User Study Overview Twelve participants: o Mix of male/female. o Early Twenties. o Students, mixed backgrounds. Navigation paths: o 5 Paths, 5 waypoints each. o Pass through each waypoint. o Random path order. 11

12. User Study Results Indirect fastest overall. Users more confident using both indirect and dynamic. Static performed worse on more complex paths. 12

13. Conclusion Three fully functional gestures sets. Dynamic gestures meet the design criteria best. Indirect are the most intuitive. Static are the most difficult to control. 13
