Prosthetic devices and methods and systems related thereto

摘要

Prosthetic devices, methods and systems are disclosed. Eye position and/or neural activity of a primate are recorded and combined. The combination signal is compared with a predetermined signal. The result of the comparison step is used to actuate the prosthetic device.

主权项

1. A prosthetic device able to assume a spatial position on input of a subject, the prosthetic device comprising:
means for recording eye position information of the subject to produce an eye position signal; means for recording a neural activity of the subject to produce a neural activity signal; means for storing at least one predetermined behavioral pattern, the at least one predetermined behavioral pattern associated with at least one spatial positioning of the prosthetic device; processing means coupled to the means for recording eye position information, the means for recording a neural activity and the means for storing, the processing means receiving an eye position signal from the means for recording eye position information during a scan stage occurring after the subject views a plurality of reach goals but before the subject selects one of the plurality of reach goals, receiving a neural activity signal from the means for recording a neural activity signal during neural activity occurring during the scan stage, combining the eye position signal and neural activity signal recorded only during the scan stage to produce a recorded behavioral pattern, predicting a selection of one of a plurality of reach goals by comparing the recorded behavioral pattern and the at least one predetermined behavioral pattern to identify a matching predetermined behavioral pattern, the recorded behavioral pattern associated with a selection of one of the plurality of reach goals after the scan stage, and outputting a spatial position control signal associated with the matching predetermined behavioral pattern; and means for positioning the prosthetic device coupled to the processing means to receive the spatial position control signal and position the prosthetic device in a spatial position associated with the matching predetermined behavioral pattern.
