Evaluation of accuracy: A comparative study between touch screen and midair gesture input

Abstract

This paper presents a user study on the accuracy measure between Touch Screen and Leap Motion Controller. Touch screen is a popular way to input text whereas leap motion controller is an emerging input device that captures the natural movement of hand. The object of this paper was to approach an affordable and more accurate method of input technology as well as to specify in what cases Leap motion could act as good as or better than Touch screen. For this purpose a program was developed that generated targets that had to be selected by the user. On the basis of the performance of users in the experiment the results were generated. There was a need to be able to compare both input modalities from human performance perspective. New methods of user interface require the developers to rethink about the technologies incorporated in the new products.
