intangibleCanvas: free-air finger painting on a projected canvas Conference Paper uri icon


  • With the advent of new sensing technologies, precision free-air interaction is becoming viable as a contender for the next generation of expressive, embodied interaction modalities. ZeroTouch [5], a novel multi-touch sensor that allows for free-air multi-finger, multi-object sensing, is one example of this next generation of free-air interfaces. We develop its use in a digitally-projected finger painting application, placing the see-through multitouch sensor in direct line-of-sight between an artist and a remote canvas. This allows the artist to reach through the sensor and paint on the intangibleCanvas as if it were directly in front of them. An iPad is employed as a multimodal workspace for color selection. We evaluate the system through an informal walk-up-and-play installation and comparative study, developing implications for interaction design using this type of precision free-air interface.
