Portable visually impaired voice navigation system for indoor use

This creation is about a portable visually impaired voice navigation system for indoor use, especially an acceleration sensor and an electronic compass to detect the distance and direction of visually impaired people walking, by acceleration sensor, electronic compass And the Bluetooth-designed portable device transmits the data of the acceleration sensor and the electronic compass to the mobile phone or tablet through the Bluetooth module, and the application software (APP) of the mobile phone or tablet calculates the visually impaired person to move indoors. The coordinates of the camera are installed in the indoor entrance and exit of the infrared sensor and the Bluetooth module. The infrared sensor senses the position of the visually impaired person and transmits the coordinates to the mobile phone or tablet through the Bluetooth module to correct the visually impaired person moving indoors. Coordinates, with the pre-entered home map of the mobile phone or tablet, the visually impaired person can use voice to input the destination, and the TTS tool built in the mobile phone or tablet can tell the visually impaired how to reach the destination.

In recent years, electronic technology has developed rapidly. The visually impaired mobile assistants include tools such as mechanical guide dogs, guide canes and guide blind robots. The ZigBee wireless sensor network is used to develop office personnel positioning systems and utilize ZigBee wireless sensors. The Internet is used as a voice navigation aid system for the visually impaired person's home life to help the visually impaired's home life more convenient. There are many methods at home and abroad to calculate the trajectory, including the image recognition method and the method of simulating the human eye. However, due to the large amount of image data, the recognition complexity is increased, and the cost is increased. It is a method for monitoring the trajectory of short time and small field. The acceleration sensor can be used to measure the number of walking steps converted into exercise energy consumption, but no calculation of the travel trajectory function. The positioning function of the satellite navigation system is mainly applicable to the environment where the satellite wireless signal can be received outdoor to obtain the coordinates of the mobile. As for the indoor positioning system, using the ZigBee wireless sensor network to develop the positioning system is costly, and the reference node of the ZigBee wireless sensor network and the computer receiving positioning information system cannot be made low-cost and miniaturized. Easily carried equipment is also very inconvenient for indoor visually impaired people.

In view of the shortcomings of the above-mentioned visually impaired voice navigation system, the present inventor can not meet the needs of consumers, and is improved, and finally successfully developed and completed this creation.

The portable visually impaired voice navigation system that can achieve the above-mentioned new purpose first establishes a map coordinate system for the indoor environment. After entering the door, the visually impaired person has an infrared sensor and a Bluetooth module at the door to sense the visually impaired person. Transfer the starting coordinates (0,0) through the Bluetooth module to the phone or tablet, then use the accelerometer and electronic compass to detect the distance and direction of the visually impaired, and the acceleration sensor and electronic compass The data is transmitted to the mobile phone or tablet through the Bluetooth module, calculating the coordinates of the visually impaired person moving indoors, and placing infrared sensors on the important entrances and exits of the indoor environment such as the gate, bedroom, bathroom, etc. to sense the visual impairment. When the person passes, the Bluetooth module transmits the coordinates of the location to the mobile phone or tablet to correct the coordinates of the visually impaired person moving indoors, and the home map that is pre-entered by the mobile phone or tablet computer, and the visually impaired person inputs the destination by voice. You can tell the visually impaired how to get to your destination by using the text-to-speech (TTS) tool built into your phone or tablet.

In particular, it uses an acceleration sensor and an electronic compass to detect the distance and direction of the visually impaired person, and transmits the data of the acceleration sensor and the electronic compass to the mobile phone or tablet through the Bluetooth module to calculate the visual impairment. The coordinates of people moving indoors, put infrared sensors on the entrances and exits of indoor environments such as gates, bedrooms, bathrooms, etc. to obtain the coordinates of the visually impaired people moving through the coordinates of the visually impaired people, and get accurate views. The mobile phone of the disabled person, the visually impaired person uses voice input destination to the mobile phone or tablet, the voice recognition of the mobile phone or tablet will cover the destination, and the visually impaired person will use the voice to determine, and then according to the set home map and the current visually impaired When the position of the person is compared, it is necessary to remind the visually impaired person to change the direction of the position, compile the phonetic sentence with the code, and release the phonetic sentence from the mobile phone or tablet computer carried by the visually impaired person through the earphone, and the speech sentence needs to change direction. , near the obstacles, to the destination, furniture at home, doors, windows, bathrooms, bedrooms, supplies, To position such as toilets, bathrooms, restaurants, etc., and to navigate important matters every day, the phonetic code can be designed and navigated in combination. The code code code is in the order of current position, walking steps, conversion direction, nearby Home goods, important locations and destinations, such as "doorway" "walking" "three" "after the step" "right turn" type, the app can use the built-in TTS tool to play the home navigation speech to the visually impaired To enable visually impaired people to reach their destination smoothly.
