Behand was a novel way of interaction that allowed mobile phone users to manipulate virtual three-dimensional objects inside the phone by gesturing with their hand. Behand provided a straightforward 3D interface and extended the phone’s input and display space. It is ergonomically appropriate and technically feasible. Behand was the outcome of a design case project with Luz Cabellero and Valentina Occhialini at the Industrial Design department of the Technical University of Eindhoven. Our supervisor was Andres Lucero, who worked for Nokia at the time. Behand won the Student Design Competition at MobileHCI in 2010.
