Perceptual Issues in Haptic Digital Watermarking
— The growing interest in haptic applications such as skill training, museum displays, multimodal interfaces, aids for people with visual and/or hearing impairments, etc suggests that haptic digital media will soon become widely available, and the need will arise to protect digital haptic data from misuse. One of most common data protection technologies is digital watermarking, which consists of embedding a digital code into multimedia data file. The code should not interfere with the normal use of the media but can be always recovered to prove data ownership. To that end, the embedded code must be imperceptible to the user. Since this requirement also holds for haptic digital media, it is then necessary that human’s ability to perceive a hidden signal through a haptic interface be carefully studied. Hence this paper aims at presenting the first results of the psychophysical experiments we have conducted in this context. KEYWORDS Haptics, digital watermarking, perception.
