SENSORY BAND FOR OBSTACLE DETECTION IN THE VISUAL FIELD OF A USER WITH VISUAL IMPAIRMENT

摘要

The present invention relates to the technical field of physiotherapeutic apparatuses and devices for locating or stimulating reflex points in the body of a patient. Specifically, it provides a sensory band comprising a frame having two arched arms, two antennas, a pair of ultrasonic transducers, three vibrators, and a microcontroller operatively connected to said pair of ultrasonic transducers, and to said three vibrators. The present invention further provides an obstacle detection method that implements said sensory band and comprises the steps of transmitting an ultrasonic wave by means of said pair of ultrasonic transducers; measuring the reflection of said ultrasonic wave by means of said pair of ultrasonic transducers; providing vibrations to said three vibrators on the basis of the reflection characteristics of said ultrasonic wave; wherein said vibration varies depending on the reflection characteristics of said ultrasonic wave.
