What is the gesture follower ?
The gesture follower is a ensemble 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 get parameters from the comparison between a performance and an set 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 ? (beginning, middle or end of the gesture)
What is a gesture anyway ?
A gesture here can be any multi-dimensional temporal curve, sampled at relatively low frequency compared to sound. With the current implementation in Max/MSP the frequency sampling period must be at least 1 milisecond, but typically, 10-20 milisecond is recommended. There are no upper limit (if you have time...).
There is no technical limit for the dimension of the gesture data (or number of sensor channel) other than what your computer can afford as a CPU load (for example 20 is generally no problem).
In Max/MSP the data feeding the gesture follower can be taken from a list, for example:
- sound parameters (pitch, amplitude, etc)
- mouse, joystick coordinates
- parameters from video tracking (EyesWeb, Jitter, etc)
- Wiimote
- MIDI
- any sensors data, etc...
- any combination of the above (you said multimodal ?)

Getting started
LCD example
1st step : Record gestures
Let’s start with two simple drawings : a triangle and a circle.
2nd sep : Compare
Draw a figure and then see how similar it is with your two referent drawings.
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.
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).
Examples
In the version v0.3, the following examples can be found:
- writing
- Wii
- audio parameters (pitch, periodicity, energy)
- voice (mfcc)
