Abstract

Digital art technologies take advantage of the input, output and processing capabilities of modern computers. However, full digital systems lack the tangibility and expressiveness of their traditional counterparts. We present Ghost Touch, a system that remotely actuate the artistic medium with an ultrasound phased array. Ghost Touch transforms a normal surface into an interactive tangible canvas in which the users and the system collaborate in real-time to produce an artistic piece. Ghost Touch is able to detect traces and reproduce them, therefore enabling common digital operations such as copy, paste, save or load whilst maintaining the tangibility of the traditional medium. Ghost Touch has enhanced expressivity since it uses a novel algorithm to generate multiple ultrasound focal points with specific intensity levels. Different artistic effects can be performed on sand, milk&ink or liquid soap.
