Résumé
We investigate the design of a shape-changing dial, i.e. a dial that can change its circumference and height to adapt to different contexts of interaction. We first explore how users grasp 3D printed dials of different heights and circumferences in order to inform the form factor of shape-changing dials. We then design a prototype, ExpanDial, inspired from morphing origami. We then use our prototype as a probe within design sessions and use the participants' feedback to devise a set of applications that can benefit from such reconfigurable devices. We also used the design sessions to better understand what kind of interaction and manipulation could be harnessed from such device.
