Abstract

This paper presents a smart glasses-augmented, wearable input device based on a wristband-type, motion-aware touch panel. With this novel input device, a user can manipulate the smart glasses' augmented reality (AR) system by selecting and moving contents via touching and dragging, as well as scrolling, navigating, and controlling 3D objects by rotating the wrist. The proposed device can be used in an AR environment to select and manipulate virtual 2D and 3D content. The proposed interface offers the following advantages: 1) the touch screen panel helps users to control the smart glasses' AR system accurately, without any limitations of gesture and speech recognition systems; environmental noise and distortion, and multi-leveled pattern recognition task; 2) the motion of the wrist increases the Degrees of Freedom (DOF) of the system - the combination with 2 DOF of touch interaction allows accurate 3 DOF interaction and various ways of interacting, enabling users to carry out tasks via a Head-Mounted Display (HMD) quickly and intuitively; and 3) the simple hardware composition allows the device to be easily embedded into existing devices such as smart watches.
