Lecture of Fazel Naghdy: Haptic Rendered Practice Carillon

Invitation to the lecture of Fazel Naghdy: "Haptic Rendered Practice Carillon"
Abstract:
The development of a haptic rendered device emulating the sonic and the
tactile dynamics of a carillon, specifically the National Carillon in
Canberra, Australia, is presented. The carillon is one of only a few
instruments that elicit a sophisticated haptic response from the amateur and
professional player alike. Force-feedback varies widely across the range of the instrument and developing an intuition for the heaviness of different
bells is a critical part of carillon pedagogy.
Unfortunately, rehearsal time available to individual carillonneurs is
limited by competition from other carillonneurs and environmental factors
like civic noise limits and carillon maintenance schedules. Rehearsal
instruments do exist but they do not accurately display the haptic dynamics
of the real carillon.
Like the piano keyboard, the velocity of a player's impact on each carillon
key, or baton, affects the quality of the resultant tone; unlike the piano,
each carillon baton returns a different force-feedback. Force-feedback
varies widely from one baton to the next across the entire range of the
instrument and with further idiosyncratic variation from one instrument to another.
During the presentation, the haptic modelling of the carillon will be
described and the performance of a prototype key of the carillon developed
in this study will be demonstrated.
