In people, spirit is fully immersed the thing for wherein, having no time to attend to surrounding while with handset processes routine matter, so can lead
Cause people on the way using can be bumped against when mobile phone barrier even other people or bicycle.It currently there are no very convenient solution
The method of this problem.
Blind person has many inconvenience in life, according to relevant information, has 5,000,000 in China as the disadvantaged group in crowd
Blind person, there is 18% blind person in the world in China.For blind person because the impediment of itself, it is also one to them that can freely walk
Kind extravagant hope, walking stick, seeing-eye dog etc. are always the instrument that blind person relies on.But animal seeing-eye dog time consumption for training is longer, mortality is high,
It is expensive, the powerless purchase of ordinary people.Blind-guiding stick can be divided into traditional two kinds of blind-guiding stick and electronics blind-guiding stick.Traditional blind-guiding stick knot
Structure is simple, only common wooden stick or the rod of other materials, and its major function is exactly constantly to tap ground by blind person to visit
Solid obstacle in bright front 0.5m distances.Electronics blind-guiding stick is by adding ultrasonic probe, infrared probe or camera pair
Front is fixed and moving object is detected, and sending hydropac to blind person user when finding obstacle arouses attention, guiding
Its avoiding obstacles, by using electron detection means, expand the detectable area of blind-guiding stick.Wearable guide accessory system
More based on the supersonic sounding device that is configured on glasses, avoidance effect is poor.
Due to the limited height of blind-guiding stick, it is not easy to be detected for half hanging high obstacle thing；In addition common guide is auxiliary
Auxiliary system is prompted using alarm tone or voice, and in a noisy environment, this alarm would generally be by larger shadow
Ring, while only a few has the visually impaired person of dysaudia, then can not use phonetic warning；Using during blind guiding bar, it is necessary to take one
Hand, will some inconvenience so when visually impaired person needs bimanualness；Some wearable guide accessory systems, it is each to wear
It is all to judge alone to wear device, for example when running into a higher barrier, the body wearing point in barrier height can all be carried out
Alarm.Some centralized wired connections are made troubles the wearing of device again.
The patent application of Application No. 201010570913.9, a kind of infrared blind guiding mobile phone, including mobile phone body, in institute
