Haptic Games for the visually impaired

Visually disabled people increasingly use computers in everyday life, thanks to novel assistive technologies better tailored to their cognitive functioning. Like sighted people, many are interested in computer games – videogames and audio-games. Tactile-games are beginning to emerge. The Tactile Radar is a device through which a visually disabled person is able to detect distal […]

Spatial Physical Computing with the Gluons

Latest hardware improvements on transceivers supporting Low Power Wide Area Networks (LP-WAN) make it feasible to connect small battery powered devices hundred (or even thousands) of meters apart. We propose a physical computing paradigm fully exploiting this novel technology dubbed Spatial Physical Computing (SPC). An SPC system leverages not only natural manipulation typically used on TUI and […]


Ratchair is a strategy for displacing big objects by attaching relatively small vibration sources. After learning how several random bursts of vibration affect its pose, an optimisation algorithm discovers the optimal sequence of vibration patterns required to (slowly but surely) move the object to a specified position. We designed sources of vibration that can be easily […]
