Designing Multi-Touch Gestures Using the Space around the Smartwatch as Continuous Input Space
summary
Proposes transture: touchscreen gestures register, cross the bezel into a glue state, continue as mid-air input, then terminate. Prototype uses an optical tracking system and evaluates dragging at 10/20/40 mm; accidental transture starts occur 0.52% and failed activations 0.87%, so relaxation via “keep-moving across bezel” is reliable. Height-based termination proves awkward, so termination switches to a speed-based threshold. Also designs a multi-touch start by opening fingers while one remains on the screen.
