Blackshaw, Matthew, DeVincenzi, Anthony, Lakatos, David, Leithinger, Daniel and Ishii, Hiroshi (2011): Recompose: direct and gestural interaction with an actuated surface. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 1237-1242. http://dx.doi.org/10.1145/1979742.1979754

In this paper we present Recompose, a new system for manipulation of an actuated surface. By collectively utilizing the body as a tool for direct manipulation alongside gestural input for functional manipulation, we show how a user is afforded unprecedented control over an actuated surface. We describe a number of interaction techniques exploring the shared space of direct and gestural input, demonstrating how their combined use can greatly enhance creation and manipulation beyond unaided human capability.

Leithinger, Daniel, Lakatos, David, DeVincenzi, Anthony, Blackshaw, Matthew and Ishii, Hiroshi (2011): Direct and gestural interaction with relief: a 2.5D shape display. In: Proceedings of the 2011 ACM Symposium on User Interface Software and Technology 2011. pp. 541-548. http://dx.doi.org/10.1145/2047196.2047268

Actuated shape output provides novel opportunities for experiencing, creating and manipulating 3D content in the physical world. While various shape displays have been proposed, a common approach utilizes an array of linear actuators to form 2.5D surfaces. Through identifying a set of common interactions for viewing and manipulating content on shape displays, we argue why input modalities beyond direct touch are required. The combination of freehand gestures and direct touch provides additional degrees of freedom and resolves input ambiguities, while keeping the locus of interaction on the shape output. To demonstrate the proposed combination of input modalities and explore applications for 2.5D shape displays, two example scenarios are implemented on a prototype system.
