Virtual reality (VR) in medicine may be defined broadly as a bidirectional interface between the patient and the computer. By extension of this concept, the computer can be used to recognize patterns of patient behavior in space and react to such behavior.

Standard paradigms of VR interaction present a computer-generated environment for the patient with measurement of patient response, usually followed by stereotyped changes in the computer-generated presentation. The patient's behavior is thus molded to the computer's conception of reality. But in many medical applications, the reverse philosophy must be adopted. The computer must sense the environment generated by the patient and then react intelligently to the patient. The challenge in the design of such systems then becomes one of appropriate pattern recognition and generation of response.

These principles come to the forefront in analysis of epileptic phenomena, particularly in the case of complex partial seizures. Adaptation of principles developed in VR approaches can enhance detection and diagnosis of partial seizures.
