Spotted: an alternative to pinch-to-zoom #spots #mobiles #ui

Bill is a true ui pioneer. It's good to see someone questioning the new mobile "wimp ".

Toward compound navigation tasks on mobiles via spatial manipulation

Michel Pahud, Ken Hinckley, Shamsi Iqbal, Abigail Sellen, Bill Buxton

We contrast the Chameleon Lens, which uses 3D movement of a mobile device held in the nonpreferred hand to support panning and zooming, with the Pinch-Flick-Drag metaphor of directly manipulating the view using multi-touch gestures. Lens-like approaches have significant potential because they can support navigation-selection, navigation-annotation, and other such compound tasks by off-loading navigation to the nonpreferred hand while the preferred hand annotates, marks a location, or draws a path on the screen. Our experimental results show that the Chameleon Lens is significantly slower than Pinch-Flick-Drag for the navigation subtask in isolation.
