Pen Mid Air: An Exploration of Mid Air Gestures to Complement Pen Input on Tablets
In this paper, we report on a series of studies, exploring the potential of pen and mid air input on tablets. We describe a field study with an early prototype of a drawing application and follow up inquiries, such as the development and comparison of gesture sets for pen and mid air input and pen and multi touch input with users in a lab environment. Overall, our results suggest that pen and mid air input should be offered to complement traditional pen and multi touch input on tablets. We illustrate the final user defined gestures set for pen and mid air input and discuss how user preferences of mid air gestures over touch gestures seem to depend on the complexity of operations and the need of additional menus on the screen.
