Abstract

This study formulated existing virtual pointing techniques for cursor control in the mobile context of touchscreen thumb operation. Three virtual pointing models were developed, including: Virtual Touchpad, Virtual Joystick and Virtual Direction Key. In order to verify their usability and feasibility, a user study was employed to evaluate the usability of three virtual pointing models, followed by the focus group interview to experienced usability designers, in which, constraints of touchscreen cursor control in mobile context were defined and rated against three virtual pointing models. Research findings: (1) Virtual Touchpad was significantly efficient than others, while Virtual Direction Key presented lower error rate, although insignificantly. (2) Constraints of touchscreen cursor control in mobile context include: stable and simple operation, Interruptible operation is better and avoids accurate pointing. Virtual Direction Key stood out as the most stable, simple and interruptible pointing control.
