METHOD AND APPARATUS FOR ENCODING AND DECODING HAPTIC INFORMATION IN MULTI-MEDIA FILES

Abstract:

A method for encoding haptic information inside a multi-media file having content includes changing a portion of the content in the multi-media file, and adding the haptic information to the changed portion of the content, the haptic information corresponding to a haptic signal for generating a haptic effect upon playback of the multi-media file. A method for decoding haptic information from inside a multi-media file having content includes locating the haptic information inside the multi-media file, and generating a haptic signal based on the located haptic information during playback of the content of the multi-media file. A method includes receiving a multi-media signal comprising an audio signal and a haptic signal with a receiver of a haptic device, and outputting a haptic effect with a haptic output device of the haptic device based on the haptic signal in the multi-media signal.
