PDA and Gesture Uses in Practice: Insights for Designers of Pen-based User Interfaces
Abstract: Gestures are an essential element in the realization of paper-like user interfaces. Unfortunately, poor design and recognition of gestures has impeded the adoption of these interfaces. This paper describes a survey intended to illuminate the problems users have and benefits users enjoy with gesture-based user interfaces. From the results of the survey, we conclude that: users value gestures yet problems with gestures remain; users demand more gestures; and Newtons are used largely as notebooks whereas Pilots are used mostly as personal datebooks and addressbooks. The results of the survey provide insight for designers of pen-based user interfaces and related tools.
