Acquiring and pointing: an empirical study of pen-tilt-based interaction

Research literature has shown that pen tilt is a promising input modality in pen-based interaction. However, the human capability to control pen tilt has not been fully evaluated. This paper systematically investigates the human ability to perform discrete target selection tasks by varying the pen stylus' tilt angle through two controlled experiments: tilt acquiring (Experiment 1) and tilt pointing (Experiment 2). Results revealed a decreasing power relationship between
