The Evaluation of Pen Gestures in a Digital Painting Environment

摘要

Academic researchers argued that the use of pen-gesture commands in a pen-based environment could contribute to the improvement of task efficiency. However, previous research on pen-gesture commands tended to be focused on PDAs. A graphics tablet is also a pen-based input device. Therefore, it is possible to get better task efficiency while applying pen-gesture commands on a graphics tablet for a digital painting environment. The effects of pen-based input devices and command operations on subjects' task efficiency and the System Usability Scale (SUS) were explored in this paper. The results indicated that pen-gesture commands provided better task efficiency in file editing, layer control and integrated applications. The result from the SUS showed that pen gestures with a rubber grip pen got better usability.
