This paper presents an approach to reduction noise of speech voice commanded automatic wheel chair using a technique based on the fuzzy ARTMAP neural network (FAMNN). The measurable output noisy speech with 5dB, 1dB, -1dB, -5dB and -10dB SNR level is obtained as the contaminated signal of the interference to compare with the output data of the filter. The white noise source is acquired as the i...

This work presents a novel approach to gesture recognition system using accelerometer MEMS sensor in addition with ultrasonic obstacle detection. Gesture recognition has been extensively investigated and has traditionally been accomplished by methods based on joystick and camera based vision where camera is always tracking the movement of different body parts like face, eye etc. In our research...
