Smart eye system for Visuomotor dysfunction diagnosis and its operant conditioning
First Claim
1. A method for diagnosing visuomotor dysfunction of a subject during a visuomotor task, the method comprising the following steps:
- monitoring eye parameters of the subject;
detecting a bio-signal of the subject;
sensing physical parameters of the subject, anddiagnosing a visuomotor dysfunction based on the eye parameters, the bio-signal, and the physical parameters of the subject.

Abstract
Disclosed herein is a system that uses an eye tracker for diagnosing and facilitating rehabilitation therapy of a patient suffering from disability. The system creates a human machine interface (HMI) that integrates various low cost biosensors and artificial sensors for conducting rehabilitation therapy. The system combines spinal and supra-spinal feedback of the patient with the operant conditioning to facilitate visuomotor balance therapy (VBT), thereby reducing fall risk in disability survivors. The operant conditioning setup for shaping of visuomotor learning to bring about new behavior or to modify a certain aspect of an existing behavior is used for rehabilitation therapy that includes a behaviour response apparatus, a reward delivery module, a stimulus delivery system, and a behaviour control system. The system can also be extended to the patient'"'"'s home for providing telerehabilitation therapy.

6. A method for closed loop stimulation of central nervous system (CNS) in conjunction with peripheral nervous system (PNS) of a subject in a treatment of visuomotor dysfunction, the method comprising the following steps:
-
monitoring eye parameters of the subject and generating an eye gaze data based on the eye parameters; detecting cortical biosignal data and spinal biosignal data of the subject; sensing physical parameters of the subject; generating a first output signal based on the cortical biosignal data and the eye gaze data; generating a second output signal based on the spinal biosignal data and physical parameters; generating a plurality of stimuli based on the first and second output signals; and stimulating the central nervous system (CNS) and the peripheral nervous system (PNS) of the subject based on the plurality of stimuli. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method for operant conditioning with a subject in loop during a visuomotor task in a treatment of visuomotor dysfunction, the method comprising the following steps:
-
monitoring eye parameters of the subject and generating an eye gaze data based on the eye parameters; detecting cortical biosignal data and spinal biosignal data of the subject; sensing physical parameters of the subject; generating a first output signal based on the cortical biosignal data and the eye gaze data; generating a second output signal based on the spinal biosignal data and physical parameters; generating a plurality of stimuli based on the first and second output signals; delivering a spatiotemporally patterned stimulus coordinated with a visuomotor behavior to central nervous system (CNS) and peripheral nervous system (PNS) of the subject by a way of the plurality of stimuli for shaping of visuomotor learning by a way of perceptual and attentional learning approaches; and delivering a spatiotemporally patterned reward coordinated with the visuomotor behavior to the subject by a way of the plurality of stimuli for shaping of the visuomotor learning, thereby prodding the subject to use affected portion more than unaffected portion to perform the visuomotor task and reducing compensatory mechanisms of the unaffected portion of the subject. - View Dependent Claims (14, 15, 16, 17)
