ABSTRACT
Although intuitive in its nature, touch-based interface has the problem of poor performance time and accuracy. It also suffers from the finger occlusion problem where the objects underneath the contact area are obscured. Several techniques have been proposed to solve these problems, In this research, a technique called Fingerhit is proposed. Fingerhit uses a pseudo finger-occluded area to perfonn hit-testing and is lift-point determinant when activating an object on the screen. An experiment is conducted to compare the proposed technique against two other techniques called Cursor and Touch pointer. The results show that Fingerhit is better in terms of learning, performance time, and accuracy. Subjective responses also shmv that Fingerhit is more favorable compared to the other two techniques. We also discuss the implications and limitations of this research.
