Embodiment 2

[0126] Figure 9 The top schematic diagram of the blind guide device in the embodiment of the present application is shown Figure II , as shown in the figure, the user can wear the blind guidance device on the head, the protruding part 1 in the figure can represent the face orientation, the connecting rod 2 is connected with the rotating shaft 3, and the connecting rod 2 can be the rotating shaft 3 as the The center rotates, and the counterweight 4 can slide on the connecting rod 2 .

[0127] Figure 10 A schematic diagram of the structure of the counterweight indication in the embodiment of the present application is shown. As shown in the figure, it is assumed that the blind user faces due north and receives an external command at this time. the direction of the arrow).

[0128] The blind guiding device can control the counterweight to slide 3cm to the left of the center of the connecting rod, and the blind person can feel the head slightly deviated to the left, and then...

Embodiment 3

[0133] The blind guidance device in the embodiment of the present application may be a ring worn on the user's shoulder or waist, which will be described below.

[0134] Figure 12 The top schematic diagram of the blind guide device in the embodiment of the present application is shown Figure 3 , as shown in the figure, it is assumed that the blind guide device is a device that can be worn around the waist (similar to a belt), and the mechanical device can include a circular slide and balls, and the position of the balls in the figure can indicate the position of the user's stomach .

[0135] In the embodiment of the present application, after determining the target direction, the blind guide device can control the ball to slide along the annular slideway to the target direction, and the center of the annular slideway (also referred to as the The direction vector from the center of the circle) to the ball is the target direction, and the user can adjust his travel direction...

Abstract

The invention provides a blind guiding method, device and equipment. The blind guiding method comprises the steps that target direction is determined; a mechanical device is controlled to shift the center of gravity to the target direction according to the target direction. Due to the fact the target direction is indicated through a center-of-gravity shift mode, instructions of different directions are acted on the head of a user in a pressure mode, and the user can feel the center-of-gravity deviation of the head easily; due to the fact that when a person walks, the walking direction and the head orientation are the same, the blind can find the target direction rapidly by indicating the head to shift to the target direction. According to the technical scheme, compared with an indicating mode of an existing voice command, the user does not need to understand the meaning of the voice command by consuming a period of time, shift of the mechanical center of gravity can make the user directly feel the direction indication, and therefore the blind guiding efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of intelligent devices, and in particular, to a method, device and device for guiding the blind. Background technique [0002] Blind people are always inconvenient to go out due to their vision defects. In order to meet the living needs of blind people, various blind guide devices have appeared. At present, most of various intelligent blind guidance devices sense the surrounding environment through various sensors, calculate a reasonable roadblock avoidance path, and guide the user to move forward through voice commands (such as: turn left, turn right, etc.). [0003] The intelligent blind guide device guides the user forward through voice commands. From the user's acceptance of the voice command, to the user's understanding, and the final execution, it requires a long process, so the efficiency is low. [0004] The deficiencies of the existing technology are: [0005] The guidance efficiency of ...
