ABSTRACT The simulation of visual hallucinations has multiple applications. The authors present a new approach to hallucination simulation, initially developed for a performance, that proved to have uses for individuals suffering from certain types of hallucinations. The system, originally developed with a focus on the visual symptoms of palinopsia experienced by the lead author, allows real-time visual expression using augmented reality via an iPad. It also allows the hallucinations to be converted into sound through visuals sonification. Although no formal experimentation was conducted, the authors report on a number of unsolicited informal responses to the simulator from palinopsia sufferers and the Palinopsia Foundation.
