Embodiment 1

[0118] Figure 4 shows the top schematic view of the blind guide device in the embodiment of the present application Figure 1 , as shown in the figure, the user can wear the blind guide 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 take the rotating shaft 3 as The center rotates, and the counterweight 4 can slide on the connecting rod 2 .

[0119] Figure 5 It shows a schematic diagram of the guiding scene in the embodiment of the present application. As shown in the figure, it is assumed that the current location of the blind user is point A, and the place (that is, the destination) that the blind user wants to go to is point B, and the upper part of the figure represents the direction of true north .

Embodiment 2

[0126] Figure 9 shows the top schematic view of the blind guide device in the embodiment of the present application Figure II , as shown in the figure, the user can wear the blind guide 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 take the rotating shaft 3 as The center rotates, and the counterweight 4 can slide on the connecting rod 2 .

[0127] Figure 10 It shows a schematic structural diagram of counterweight indication in the embodiment of the present application. As shown in the figure, the wig blind user faces due north, and receives an external instruction at this time, and the instruction indicates that the target direction is 30° from north to west (the solid line in the figure in the direction of the arrow).

[0128] The blind guide device can control the counterweight to slide to the left side of the center of the connecting ...

Embodiment 3

[0133] The blind guide 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 shows the top schematic view of the blind guide device in the embodiment of the present application Figure three , as shown in the figure, assuming that the blind guide device is a device that can be worn around the waist (similar to a belt), the mechanical device may include a circular slideway and a ball, and the position of the ball in the figure may indicate the position of the user's stomach .

[0135] In the embodiment of the present application, after the blind guide device determines the target direction, it can control the ball to slide along the ring-shaped slideway to the target direction, and the center of the ring-shaped slideway (also called is the center of the circle) to the direction vector of the ball is the target direction, and the user can adjust his direction of travel after fe...

Abstract

The present application provides a blind guiding method, device and equipment, including: determining a target direction; and controlling a mechanical device to shift the center of gravity to the target direction according to the target direction. Since the embodiment of the present application indicates the direction of the target by shifting the center of gravity, the indications of different directions act on the user's head in the form of pressure, so that the user can easily feel the center of gravity of the head. When walking, the direction of travel is consistent with the direction of the head, so instructing the head to turn to the target direction can allow the blind to quickly find the target direction. Compared with the existing voice instruction method, the technical solution provided by the application does not require users It takes a while to understand the meaning of voice commands, and the shift of the mechanical center of gravity allows users to directly feel the direction instructions, thereby improving the efficiency of blind guidance.

Description

technical field [0001] The present application relates to the technical field of smart devices, in particular to a blind guiding method, device and equipment. Background technique [0002] It is always inconvenient for the blind to go out due to visual defects. In order to meet the living needs of the blind, various guide devices for the blind have appeared. At present, various intelligent blind guide devices mostly perceive the surrounding environment through various sensors, calculate reasonable roadblock avoidance paths, and guide users 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. It takes a long process from the user to accept the voice command, to the user's understanding, and finally to execute it, so the efficiency is low. [0004] The deficiencies in the prior art are: [0005] The guidance efficiency of the existing blind guide device to gu...
