Interaction Technique Using Non-Gaze Area for Fast Target Pointing and Its Evaluation.

Abstract

In a general GUI environment, it is difficult to detect an object that a user wants to look at. However, detecting objects within the non-gaze area is easy, and using this region enables us to perform a new interaction. In this paper, we propose a fast target-pointing technique using the non-gaze area. The cursor speeds up in the non-gaze area for fast pointing and slows down to normal speed near the gaze point for fine-grained pointing. In a square-clicking experiment, we compared the selection time and the error rate at three cursor speed settings: the default and the maximum speed settings of the OS, and the speed setting in our technique. Our technique reduces selection time while maintaining about the same error rate compared to default speed, thereby illustrating the effectiveness of our proposed method. © 2013, Japan Society for Software Science and Technology.
