What is "the gesture follower" ?

The gesture follower is a set of Max/MSP modules to perform gesture recognition and following in real-time. It is integrated in the toolbox MnM of the library FTM (see dowload). The general idea behind it is to be able get parameters by comparing a performance with an ensemble of prerecorded examples.

The gesture follower can guess the two following questions:

  • which gesture is it ? (if you don't like black and white answers, you can get "greyscale" answers: how close are you from the recorded gestures ? )
  • where are we ? (begining, middle or end ...)

What is a "gesture" anyway ?

A gesture here can be any temporal curve, sampled at relatively low frequency compared to sound. Typically, from 1000 Hz to 0.001 Hz.

1st STEP : Record gestures

Let’s start with two simple drawings : a triangle and a circle. Example2.jpg


2nd STEP : Compare

Draw a figure and then see how similar it is with your two referent drawings. Example3.jpg


3rd STEP : Observe

Pay attention to the curves below. They represent the velocity in X and Y axis of the mouse trajectories. That give a useful temporal information on how you realize your drawing. Example4.jpg


Connection Avec EyesWeb XMI

EyesWeb XMI, the open platform for real-time analysis of multimodal interaction, can be connected to Max/Msp throughout the OSC protocol (Open Sound Control). OSC is open, message-based protocol which was originally developed for communication between computers and sythesizers (cf. wiki).
