Navigation of a 3D World via 2D Touch

Navigating 3D Worlds via 2D Multi-Touch InterfacesDaniel CopeSupervised by Stuart Marshall1MotivationMulti-Touch hardware is becoming common place.Existing solutions do not provide all six degrees of freedom.Initial applications for use with the general public.22Project ProblemTwo main problem areas:Interaction with a 2D touch surfaceNavigation through a 3D space 3D navigation based on flight simulators and 3D modelling software.Criteria for gesture sets.Intuitive, Robust, Simple, Scalable and Resistant.3Proposed SolutionsEvaluate three gesture sets.Indirect gestures.On screen joystick controls.Static gestures.Standard gestures.Dynamic gestures.Variation of static gestures.4Indirect Gestures

Dynamic Gestures10User Study OverviewTwelve participants:Mix of male/female.Early Twenties.Students, mixed backgrounds.Navigation paths:5 Paths, 5 waypoints each.Pass through each waypoint.Random path order.1111User Study ResultsIndirect fastest overall.Users more confident using both indirect and dynamic.Static performed worse on more complex paths.1212ConclusionThree fully functional gestures sets.Dynamic gestures meet the design criteria best.Indirect are the most intuitive.Static are the most difficult to control.13Any Questions?14
