A Study on the Usability Testing of Gesture Tracking-Based Natural User Interface
This paper compares the difference between the commercialized gesture trackingbased interface and the traditional computer mouse through a usability testing. It is then examined the possibility of applying this technological difference to a variety of content. To achieve this, Kinect sensor device, which is one of the commercialized gesture tracking-based interface, has been used and evaluated its performance through Fitts’ law. Fitts’ law is mainly used in human-computer interaction, which is an authorized tool to evaluate a cursor click and movement on the computer screen. In this paper, three factors – distance, width, and angle – between cursor and target are used to define the index of difficulty into 96 steps. The response time between two randomly selected cursor positions is then measured for each step. By comparing the measured time values, the possibility of using gesture tracking as an alternative interface to the computer mouse is verified.
