Extending touch-less interaction on vision based wearable device

A touch-less interaction technology on vision based wearable device is designed and evaluated. Users interact with the application with dynamic hands/feet gestures in front of the camera. Several proof-of-concept prototypes with eleven dynamic gestures are developed based on the touch-less interaction. At last, a comparing user study evaluation is proposed to demonstrate the usability of the touch-less approach, as well as the impact on user's emotion, running on a wearable framework or Google Glass.

1 Introduction

Nowadays, there is an increasing interest in creating wearable device interaction approach. Novel emerging user interface technologies have the potential to significantly affect market share in PC, smartphones, tablets and latest wearable devices such as head-wearable device(HWD), i.e. Google Glass, since the miniaturization of mobile computing devices permits ‘anywhere’ access to the information [8]. Therefore, displacing these technologies in smart devices is becoming a hot topic. Google glass has many impressive characteristics, and will not meet the occlusion problem and the fat finger problem [12], which frequently occurs in direct touch controlling mode, anymore. However, Google Glass only provides a touch pad that includes haptic with simple tapping and sliding your finger gestures, which is a one-dimensional (1D) interaction in fact and limits the intuitive and flexibility of interaction. Therefore, implementing a light-weight touch-less gesture recognition vision systems could provide a easy-to-use interaction approach. It has been proven effectiveness in virtual environments [11].
