Reminder for blind person

Technical Field

The invention relates to the technical field of blind obstacle avoidance articles, in particular to a reminder for blind people.

Background

The blind person refers to the visually impaired, and the visually impaired people are mainly divided into two categories, namely full-blind and semi-blind. Blindness (i.e., atrophy or calcification of the eyeball) is unresponsive to light. Semi-blind is amblyopia (60% below normal vision), and blind people are restricted in their activities by visual impairment.

The blind person usually adopts a walking stick or a blind guiding rod for the blind person, the walking stick is held by the blind person, the blind person is guided to move forwards by mainly exploring the way with the walking stick, and when the walking stick touches the roadblock in front, the blind person can avoid the roadblock by feeling and sensing, but the blind person can not reliably explore the way with the walking stick, the judgment error rate is high, and the blind person is easy to cause danger caused by the fact that the blind person collides the roadblock. Therefore, the prior art is in need of improvement.
