MUSIC 250B, Winter 2009, Research Page

This research page has been completed as part of the following assignment:

    Wiki "Community Service" Project

    As an end-of-term deliverable for 250b, prepare a helpful and factual Wiki page on the 
    ccrma wiki on a topic relevant to the course. The goal of the wiki page is to create a 
    repository for the facts, links and processes which sustained your work in 250b this term. 
    The target audience for this page is the collection of future CCRMA students interested 
    in HCI and music taking the 250 series of courses. Hopefully, your work will not only 
    inspire their future work but will also act as a valuable resource from which they can get 
    a head-start on similar projects, in a sense, "standing on the shoulders of giants" 
    (yes, this means you are all "giants").

     Part of the Michael's ongoing research (supported by the Social Sciences and 
  Humanities Research Council of Canada), the “GRIP MAESTRO” is the composer's 
  latest attempt to incorporate real physical resistance and haptic feedback into 
  an electroacoustic performance interface. The goals of this specific project 
  are to take advantage of a simple physical gesture (not previously utilized by 
  an existing acoustic instrument: see figure 1), and, by incorporating physical 
  resistance, create an “easy to learn / difficult to master” interface for the 
  creation of, and control over realtime electroacoustic performance in both a 
  solo and ensemble setting.
     The “GRIP MAESTRO” is a modified hand exerciser called a “Grip Master” 
  (see figure 2). By measuring the position of the pads on the device (see 
  figure 3) and carefully mapping them to parameters of music creation (see 
  figure 4), Michael hopes that the “GRIP MAESTRO” will provide the feel, control, 
  and aural feedback necessary to be an effective interface between performers and 
  their music, and between audiences and their performers.
     Presently there are two mappings of the control data prepared in the ‘strongly 
  timed’ programming language, “ChucK” (http://chuck.cs.princeton.edu/). Michael is 
  presently in the planning stages of a third, but there are a multitude of potential 
  applications and mappings for which the “GRIP MAESTRO” is ideal (see figure 5).
