LeapTrak: Exploring Smartwatch Gestures in 3D

Abstract

As mobile devices and wearables become smaller and more portable, their development becomes limited in size and hardware capabilities. This leads to difficulties with input as the size of a user’s finger can narrow the possible interactions that can be performed or occlude the screen, limiting visual feedback from the device. Inspiring by SoundTrak which presents 3D acoustic sensing techniques for smartwatches, LeapTrak expands upon this previous research through presenting a set of gestures performed in 3D space for smartwatch applications using a Leap Motion [16].
