A Comparison of Pen Pressure and Tilt in Precision Parameter Manipulation

In this paper, we comparatively investigate the performance of using pen pressure, tilt and key press, which is a reference baseline for analysis, to manipulate high precision parameters. We elaborate the experiment design framework and evaluate the three techniques. Results show that for completion time, pressure performed outstanding, key press the next, tilt the worst. For error rate, there are no significant different among these three techniques. However, tilt has the lowest error rate in 0.0026 scale conditions and no error in 0.0060 scale conditions. Results also show that tilt has the most significant learning effect, which is promising in pen-based user interface design.
