Abstract:
A method to universally connect biofeedback applications software to VRML content for providing positive or negative reinforcement to client behavior, utilizing physiological sensing devices and a computer, comprised of the steps of:a. creating a plurality of data streams of values desired to be represented and perceived in a VRML environment whereby each data stream represents the stream of data corresponding to at least one physiological measurement sensed; b. converting the values in each data stream to a converted data stream having digitized values each value representing a desired range of numbers and having a threshold value between the minimum and maximum converted value in which data values above or below the threshold value indicate the need for positive or negative reinforcement of client behavior; c. inputting the converted data streams to an eventIn of a node that is associated with a corresponding eventOut of a node, which eventOut makes the converted data stream available to a node for eventual interpolation; d. inputting the converted data stream from eventOut to said node; e. computing the interpolated values of the converted data stream to create an interpolated data stream of values; f. inputting the interpolated data streams to fields representing desired characteristics of the display within the scenegraph and such that each field is responsive to the respective desired range of numbers utilized to create the converted data stream.
