Subject: Does anyone know how to find this paper From: "Dr J.Stevenson's research assistant" <jim-ra(at)EOS.ARC.NASA.GOV> Date: Wed, 30 May 2001 15:57:41 -0700" An impressive paper from Wegner and Karron of Computer Aided Surgery Inc., described the use of auditory feedback to guide blind biopsy needle placement. Their audio feedback system generates an error signal in 3D space with respect to a planned needle trajectory. This error signal and the preoperative plan are used to motivate a position sonification algorithm which generates appropriate sounds to guide the operator in needle placement. To put it simply, harmonics versus dissonances are used to convey position information accurately along 6-8 dimensions. A nice example of a synaesthetic medium - using one modality (sound) where one would normally " I would like to know about your current audio reseach.
