Abstract: This paper presents the methodological procedures and the results of a tactile sensitivity analysis to vibrotactile stimuli. The results were obtained through the analyses between the rightness mean while identifying the target frequency, among the following characteristics: visually and hearing impaired people as well as unimpaired ones; visually and hearing impaired men and women and unimpaired ones; visually and hearing impaired children, teenagers and adults as well as unimpaired ones; visually and hearing impaired people with congenital and acquired deficiency. This is an expanded version of a paper presented at the 3rd IEEE International Workshop on Medical Measurements and Applications, 9–10 May 2008, Ottawa, ON, Canada.

Keywords: tactile sensitivity analysis; psychophysical tests; Braille display; vibratile stimulator; deaf; blind; pitch; vibrotactile stimuli; visually impaired; hearing impaired; unimpaired.
