20160030275
The present invention relates generally to a positioning system and the method for operating the same, and particularly to a blind-guiding positioning system for mobile device and the method for operating the same. The system is provided for the blind for wearing or installed in a home-care robot. Thereby, a user incapable of judging the environment using his vision can know his location via the voice method. In addition, remote family members, carers, policemen or firemen can master the user's safety real-timely.
For the blind, a well-trained guide dog is absolutely the best partner. Nonetheless, even being trained, a guide dog still can only help the blind move around the familiar area or protect their safety on the way. It cannot guide the blind to an unfamiliar destination.
To reach an unfamiliar destination, a current popular method is to us a global positioning system (GPS). This public and standard positioning technology has been extensively integrated into various portable electronic devices such smartphones. Users can use the electronic map shown on smartphones for looking up the geographical location they are currently situated. Nonetheless, this guiding method is not suitable for the blind. Instead, it is only applicable to the users with normal vision.
Accordingly, it is urged by the market demand to improve the guiding system, so that the blind can benefit from the convenience as well.
The Taiwan Patent Publication Number 200806273 disclosed an electronic blind-guiding device, which provides a blind-guiding function to the blind. The characteristic of the invention is to adopt the voice method to broadcast the location of the user. Besides, the user can input the destination using the natural language. Thereby, the electronic blind-guiding device can guide the direction by voice. On the way of movement, the device can alarm for obstacles on the road continuously and record the video of the surrounding environment. If an accident occurs, the video can be inspected for analyzing the process of the accident. Unfortunately, there exist loopholes of safety for the blind in this design. If the assistance is provided by a carer or a guide dog, the risk factors in the environment can be better reacted and thus avoiding danger. If the guide is completely replied on the guiding system, considering the limitation in the accuracy of a normal guiding system, the weather, or the instability of the system, the blind might be very possibly led to wrong areas or approaching the road sections unfriendly, such as the sections without sidewalks, to the blind. At this moment, if no emergent intervention is introduced, the possibility of accidents will be substantially increased. The post-accident analysis is virtually too late. Accordingly, the technology still needs to be improved.
An objective of the present invention is to provide a blind-guiding positioning system for mobile device, which acquires the local video by using the camera module in portable accessories such as electronic glasses. In addition, the location of the blind can be located and tracked by using the positioning module. Remote family members, caring units, policemen or firemen can hence master the user's safety real-timely.
Another objective of the present invention is to provide the operating method for a blind-guiding positioning system for mobile device. A user completes the steps via an APP. The camera module can replace the vision that the user lacks. The user can use the sense of hearing to judge safety. The video is monitored by the remote side. Hence, at the necessary moment, actions can be done for ensuring the blind's safety.
In order to achieve the above objectives, the present invention discloses a blind-guiding positioning system for mobile device and the method for operation the same. The hardware comprises a portable electronic accessory at the near side and a monitoring device at the remote side. The monitoring device receives the messages transmitted by the portable electronic accessory, which comprises a camera module, a transmission module, and a positioning module.
