Vision assist device

Abstract

The invention provides a vision assist device. The vision assist device includes guide rods, probe rods, distance detectors, controllers, and reminding devices; the probe rods are positioned on the guide rods and are perpendicularly connected to the guide rods; the distance detectors are positioned on the probe rods; each reminding device includes a measurement reminding unit and a roadblock reminding unit; the roadblock reminding units are positioned on the tops of the guide rods; the measurement reminding units are positioned on the bottom of the guide rods; and the distance detectors and the reminding devices are connected to the controller. The vision assist device is a humanistic design for special population with walking troubles due to eye diseases, is high in safety and practicability, is simple in structure, and is low in price and cost; through the distance detectors arranged on the conventional guide rods, the distance between the probe rods and the ground can be measured, and then a reminding effect can be achieved when users meet steps or roadblocks; and pressure sensors arranged on the bottom of the guide rods can control trigger of the distance detectors, and then control of power saving mode can be achieved.

Description

Technical field [0001] The invention relates to a vision aid device. Background technique [0002] A blind person is a person who suffers from an eye disease or accidental injury that causes blindness in both eyes or blindness in one eye. Due to visual impairment, blind people will encounter more difficulties than ordinary people in life and work, especially when traveling.

However, considering the special population of blind people, which have poor production capacity, these auxiliary devices have their own advantages and disadvantages in terms of their safety, practicality, and price. First, the blind track is a national public facility, and there are widespread problems of irregular design and untimely maintenance. The cane is generally a long stick made of metal, which is a guide tool for the blind to walk. The cane is a passive guide, and the roadblocks can only pla...
