2) value dimension of Consumer's Experience and business application limits popularization.
Current low speed visible ray communication (VLC) application, user mobile phone is it is generally required to more than 1 second could resolve
Information in light, Consumer's Experience is poor.Within resolution speed is risen to 0.3 second by this project, with two dimension
The sweep speed of code is suitable.Consumer's Experience is greatly promoted.As the entrance of mobile phone application, businessman can pass through
This business entrances, the information that transmission needs is to user, it is achieved the additional work(such as information reception and registration, positioning, guiding
Energy.
The entrance that Quick Response Code is applied as mobile phone, has been obtained for being widely applied, and becomes on connecting line and line
Under the effective means of (O2O).But the scanning of Quick Response Code is not only loaded down with trivial details, particularly night and light out of doors
In the case that lines part is bad, Quick Response Code scanning is difficult to carry out.Therefore, market in urgent need one can meet spy
Determine the mobile phone entry technique of environmental demand, as supplement.Visible ray communication (VLC) becomes first-selected technology.
In today that people's rhythm of life constantly promotes, lighting engineering is attracted by a lot of business premises as night
The important means of the stream of people, after all " people is phototaxis animal ".Many developers have been had not only to stop at present
Stay Lighting Design itself, and wish using lamp as business entrances, light adds content, guides consumption
Person.It is expected that the Internet of Things application of China, the market of hundred billion grades can be formed in the coming years.Visible ray leads to
News (VLC), will be the important component parts in this market.
