A human-computer interaction method and system for a blind-guiding vehicle

Abstract

The embodiment of the present invention discloses a human-computer interaction method and system for a blind-guiding vehicle. The method includes: the blind-guiding vehicle receives a data command sent by a controller; the data command is converted from a voice command received by an earphone, including Start the instruction information of the blind-guiding vehicle; the blind-guiding vehicle receives the positioning information of the fixed UWB positioning device, calculates the topological map of the line-of-sight connected domain and plans the passable path to the wristband, according to the passable path Drive towards the wristband; the blind guide vehicle periodically receives the positioning information of the fixed UWB positioning device, and updates the passable path based on the multi-sensor fusion SLAM function and dynamic obstacle avoidance function until reaching the target point.

Description

technical field [0001] The invention relates to the technical field of blind guide vehicles, in particular to a human-computer interaction method and system for blind guide vehicles. Background technique [0002] With the improvement of urban infrastructure and the diversification of transportation modes, ordinary people deeply feel the economy and convenience of travel, but the accelerated pace of social life also prevents disadvantaged groups with disabilities or limited mobility from getting more time from their families. , and traveling alone is the main problem for the visually impaired. [0003] In the past when information and electronic technology was underdeveloped, guide dogs and guide sticks played an important role, but the training and feeding of guide dogs required continuous investment, very high cost and limited service time, while traditional blind walks were in contact with guide sticks. Interactive interaction has been difficult to cope with complex urban...

Problems solved by technology

[0002] With the improvement of urban infrastructure and the diversification of transportation modes, ordinary people deeply feel the economy and convenience of travel, but the accelerated pace of social life also prevents disadvantaged groups with disabilities or limited mobility from getting more time from their families. , and traveling alone is the main problem for the visually impaired

[0003] In the past when information and electronic technology was underdeveloped, guide dogs and guide sticks played an important role, but the training and feeding of guide dogs required continuous investment, very high cost and limited service time, while traditional blind walks were in contact with guide sticks. Interactive interaction has been difficult to cope with complex urban traffic scenes, so scientific and technological workers brainstormed and presented many practical design inventions, such as smart guide sticks, smart guide electronic dogs, smart guide helmets, etc.

[0004] However, the existing guide sticks and guide electronic dogs are mainly used in specific scenarios. Human-computer interaction uses one or two sensors or actuators, such as voice prompts and vibration feedback. The entire human-computer interaction process lacks a system. Ergonomic design, lack of in-depth semantic understanding and association capabilities, and poor interactive experience in working conditions
