Supplementary Material for "Augmented Haptics - An Interactive Feedback System for Musicians"

This paper presents integrated tactiles (or vibrotactiles), a novel interface for movement and posture tuition that provides real-time feedback in a tactile form by means of interactive haptic feedback. Tactile feedback conveys information by using non-audio and non-visual form and is a promising means for movements in 3D-space. In this paper we demonstrate haptic augmentation for applications for musicians, since it (a) doesn't affect the visual sense, occupied by reading music and communication, (b) doesn't disturb in bang sensitive situations like concerts, (c) allows to relate feedback information in the same tactile medium as the output of the musical instrument, so that an important feedback channel for musical instrument playing is extended and trained supportive. Even more, instructions from the teacher and the computer can be transmitted directly and unobtrusively in this channel. This paper presents a prototype system together with demonstrations of applications that support violinists during musical instrument learning.
