I recently had a discussion with a class of music students about parsing a single dynamic data stream (in MaxMSP); the subtext was the optimization of control-gesture data in a one-to-many mapping system. The variable input from a single FSR ranges from 0 (dormant) to < 250 (dependent on force). How many different mapping modes did we achieve?

1. binary state momentary: > 1 = on, < 1 = off, using [togedge]

2. binary state latching: as above, adding a [sel 1] –> [toggle]

3. raw velocity (dynamic or continuous data, i.e. aftertouch)

4. peak, using a [gate]/[delay] system

5. delta, using [t i i] –> [-]

6. contact duration (between any ON and the next OFF), [timer]

7. trigger frequency, [counter] to tally the ON’s and some [timer],[mstosamps] maths

can you think of any we missed?

maybe they can be useful for you also.

I was really just thinking out loud, and polling the forum for their thoughts. Do you have any ideas how you would use a single number stream?

Using delta to binary (an upward movement provides a +1, and a downward movement provides a -1, regardless of how big the move)

of course, on a single stream of values one could perform an almost infinite number of operations……..my fault for ‘thinking aloud’!

mean/avg had occured to me (oh, wonderful [zl]), but I do like your delta to binary idea, especially as this is more intuitive and direct.

Thanks
Brendan

“accuracy” … how close to a perfect line is the movement of the user (per direction, one for push one for release)

similarity to last action (are the peak, the whole movement, or the duration of the last action similar to the last one?)

I like the ‘accuracy’ and ‘repeatability’ ideas, especially as my PhD context is expressive/creative gestural interaction by those with physical disabilities.

you will also have read Ross Kirk and Andy Hunt; see “Trends in Gestural Control…”
