3D Gesture Acquisition Using Ultrasonic Sensors

Research and musical creation with gestural-oriented interfaces have recently seen a renewal of interest and activity at Ircam. In the course of several musical projects, issued either by from young composers enrolled in the Cursus of Composition and Computer Music or by guests artists, the Pedagogy and Creation departments of Ircam have proposed various solutions for gesture-controlled sound s...

Object recognition with ultrasonic sensors

We have recently introduced a novel approach to sonarbased object recognition for robotics. The sonar recognition system—consisting of a Polaroid sonar coupled with an A/D data acquisition board in a LINUX-based PC— uses a fuzzy ARTMAP neural network classification system to recognize objects at varying distances. In this article we report additional results in which we test systematically reco...

Multimodal speech recognition with ultrasonic sensors

Ultrasonic sensing of articulator movement is an area of multimodal speech recognition that has not been researched extensively. The widely-researched audio-visual speech recognition (AVSR), which relies upon video data, is awkwardly high-maintenance in its setup and data collection process, as well as computationally expensive because of image processing. In this thesis we explore the effectiv...

Communications __________________ _ Obstacle a Voidance with Ultrasonic Sensors

A mobile robot system, capable of performing various tasks for the physically disabled, has been developed. To avoid collision with unexpected obstacles, the mobile robot uses ultrasonic range finders for detection and mapping. The obstacle avoidance strategy used for this robot is described. Since this strategy depends heavily on the performance of the ultrasonic range finders, these sensors a...
