METHOD AND APPARATUS FOR MULTI-DIMENSIONAL VESTIBULAR ELECTROPHYSIOLOGIC INTERFACING

原文（中国語）

Neurological interfacing with a user is performed using by one or more hardware data processors including processing circuitry and memory that receives stimulation data from at least one data input source for stimulating two or three different axes of motion and processes the stimulation data to determine at least two of pitch, yaw, and roll parameters. Based on the at least two of the pitch, yaw, and roll parameters, at least two of a yaw current signal, a pitch current signal, and a roll current signal are determined. The at least two of the yaw current signal, the pitch current signal, and the roll current signal are time-multiplexed modulated signals. A maximum current amplitude signal occurs at different times for the at least two of the yaw current signal, the pitch current signal, and the roll current signal. Output currents are generated based on the least two of the yaw current signal, the pitch current signal, and the roll current signal. The output currents are selectively applied to at least some electrodes positioned on the user's head to induce in the user at least two of a desired yaw sensation, a desired pitch sensation, and a desired roll sensation. Multiple relays are provided with each relay coupled to a corresponding current source and configured to selectively disconnect the corresponding current source from delivering a stimulation current to a corresponding electrode when the stimulation scenario requires that one or more electrodes be disconnected.
