We report here gesture analysis we performed on three different bow strokes, Détaché, Martelé and Spiccato, using this augmented violin. Different features based on velocity and acceleration were considered. A linear discriminant analysis has been performed to estimate a minimum number of pertinent features necessary to model these bow stroke classes.

The clear cerebrospinal fluid (CSF) layer surrounding the brain has previously been shown to significantly affect light distribution, and in the head the brain surface is deeply folded with many CSF filled sulci.

We observed that the detachable markers could be used to create a perception of extended body space, and that the performer perceived the stage space differently according to the auditory feedback of her action. The dancer reported that each experience with the technology shed light on her need for greater awareness and exploration of her relationships with space.

The method extracts derivative information from a single Monte Carlo simulation to permit the rapid determination of rates of change in the detected photon signal with respect to perturbations in background tissue optical properties. We then feed this derivative information to a nonlinear optimization algorithm to determine the optical properties of the tissue heterogeneity under examination.

We used a 3D motion capture system to produce animations from dance and generate the soundtrack from the dancer's movements. Movement analysis is performed to extract the important features of a particular gesture. Based on the parameters chosen from this analysis, various mappings between gesture and music are applied. In particular, the motion capture data is used to trigger and modify the timbre of sounds.

This library is built on top of the FTM library, which enables the efficient use of matrices and other data structures in Max/MSP. Mapping examples are described based on various matrix manipulations such as Single Value Decomposition. The FTM and MnM libraries are freely available.

This holographic imaging technique uses a CCD camera for recording of a digital Fresnel off-axis hologram and a numerical method for hologram reconstruction. The method simultaneously provides an amplitude-contrast image and a quantitative phase-contrast image. An application to surface profilometry is presented and shows excellent agreement with contact-stylus probe measurements.

Results show different degrees of dependence of the control temporal profiles with the dynamic level and temporal ordering of the stimuli.

Experiments with various motion capture systems are performed, including single video camera systems and a 3D optical motion capture system (Vicon 8). We present a series of demos of various approaches for motion analysis and gesture-to-sound mapping.

In most human-computer interaction paradigms, the variations in the gesture execution are commonly depicted as noise inside a gesture class. This is not the case for musical performance: each variation should be regarded as possible expression of a musical meaning [1]. Therefore, for music applications, the analysis of a given gesture could be considered as a twofold process: the recognition of a gesture class, and the characterization of the nuance embodied in its execution.

Recent examples include detecting peripheral vascular disease, compartment syndrome, and various forms of cancer (Fantini et al., 1998; Zonios et al., 1999; Benaron et al., 2000; Giannotti et al., 2000; Tromberg et al., 2000; Wariar et al., 2000; Cerussi 2001).
