We present a novel haptic actuation system for mobile phones: Two-dimensional tapering through an actuated back plate. We proposes this type of shape-change for various applications, e.g. for ergonomically actuating the shape itself, displaying internal contents, and pointing to entities located outside the device. A user study was conducted in which the accuracy of perceiving the two-dimensional tilt of the phone’s back plate is measured, as well as results from a questionnaire and a user interview. The results indicate that two-dimensional shape change may be a suitable addition to existing mobile phone technology.
