Mobile Reacher Interface for Intuitive Information Navigation

Abstract

We propose Mobile Reacher Interface (MoRIn) that is a new interface with a visual tag for a mobile device. MoRIn allows users to navigate sophisticated information structures by making natural hand gestures while holding a camera-equipped mobile terminal. The structure of an item of interest is acquired via a visual tag. The user can then navigate the structure as if he/she is handling physical objects. MoRIn greatly eases the user's cognitive loads. For instance, the user can alter the volume of an announcement by twisting terminal as if he/she were turning a dial. We describe MoRIn, some applications, and the results of a preliminary experiment.
