Blind person navigator system which is based on GPS positioning and supports hand input

Abstract

The invention relates to the technical field of navigation and discloses a blind person navigator system which is based on GPS positioning and supports hand input. The system comprises a blind guidingrod and a Bluetooth earphone. A rubber handle is sleeved at the upper end of the blind guiding rod. A controller is fixedly connected with one side of the upper end of the blind guiding rod close tothe rubber handle. An infrared sensor is embedded at the outer side of the blind guiding rod close to the lower end of the controller. A braille touch screen is embedded into the top end of the controller. According to the system, through utilization of a speech recognition system, the navigation system can send an instruction; the navigation system can position a position of a user and send the position to external mobile terminal equipment; the navigation system also can plan a walking route of the user and send the walking route to the Bluetooth earphone; the Bluetooth earphone broadcasts aplanned route to the user in a form of speech; and a blind person user also can send the instruction to the navigation system through utilization of the braille touch screen, carry out positioning and plan the walking route. The system is convenient and practical.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a navigator system for the blind based on GPS positioning and supporting handwriting input. Background technique [0002] With the development of science and technology, more and more electronic devices are used in our lives, but these technologies are rarely used in the daily life of blind people. my country is one of the countries with the largest number of blind people in the world. Therefore, blind people Traveling is a problem that cannot be ignored. Nowadays, blind people basically rely on traditional blind roads, guide sticks or guide dogs for traveling, which has led to the fact that the travel of blind people is still a big problem. [0003] A Chinese patent discloses a navigation method for the blind and a navigation device for the blind (authorized announcement number CN105832501A). Safety when reaching an intersection, but the location of the user cannot be located...

[0002] With the development of science and technology, more and more electronic devices are used in our lives, but these technologies are rarely used in the daily life of blind people. my country is one of the countries with the largest number of blind people in the world. Therefore, blind people Traveling is a problem that cannot be ignored. Nowadays, blind people basically rely on traditional blind roads, guide sticks or guide dogs to travel, which leads to the fact that the travel of blind people is still a big problem.

[0003] A Chinese patent discloses a navigation method for the blind and a navigation device for the blind (authorized announcement number CN105832501A). Safety when arriving at an intersection, but the location of the user cannot be located, and the user's walking route cannot be reasonably planned, which leads to inconvenience for blind users
