Title:
APPROACH AVOIDANCE SYSTEM AND GALVANIC VESTIBULAR STIMULATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/153792
Kind Code:
A1
Abstract:
The present invention provides a technique enabling avoiding approaching surrounding moving objects. Provided is an approach avoidance system including an imaging unit that generates an image of a surrounding environment of a subject at a time interval dT, a moving object analyzing unit that calculates a distance L between the subject and a moving object present in the surrounding environment and a relative velocity vector V of the moving object relative to the subject, and calculates, using the distance L and the relative velocity vector V, a time T required for the subject and the moving object to approach each other to a predetermined distance, a velocity calculation unit that extracts a moving object for which the time T is within a determination time Tj and calculates a velocity dV representing a magnitude and a direction of a movement the subject should make in order for a distance Lj between the subject and the extracted moving object after the determination time Tj to become a predetermined distance, an electrode unit for providing galvanic vestibular stimulation to the subject, and a current control unit that applies a current of a predetermined current value to the electrode unit to provide the galvanic vestibular stimulation to the subject to guide the subject to make the movement at the velocity dV.
