Mnemonical body shortcuts: improving mobile interaction

Motivation -- To study and validate a body space based approach to improve mobile device interaction and on the move interaction performance. Research approach -- We developed and user evaluated (20 + 10 users) an adaptive inertial sensing based system featuring default and personalized body space gesture recognition with suitable feedback. Findings/Design -- Results present gestures as suitable shortcut for on the move action triggering, improving mobile interaction performance. Research limitations/Implications -- The evaluations were performed in a controlled scenario. Further studies should be performed in more demanding situations (public transportations, stairs). Originality/Value -- The research makes a contribution on the validation of body-space gestures to improve on the move interaction performance. Take away message -- Mnemonical Body Shortcuts improves shortcut triggering both in still and on the move scenarios.
