A kind of Intelligent bracelet realizing turning wrist bright screen
Technical field
The present invention relates to Intelligent bracelet bright screen control field, be specifically designed a kind of Intelligent bracelet realizing turning wrist bright screen.
Background technology
Intelligent bracelet has been widely applied in the healthy living of people at present, has had and has replaced becoming of conventional wristwatch
Gesture.Intelligent bracelet is little due to volume, and the battery bag that can place is the least, very subtracts in the urgent need to people the most as far as possible
Few energy expenditure.For having the Intelligent bracelet of bigger display screen, people are needing the time of seeing, heart rate data or other merit
Can data time, need to go click on screen or need to go by the button in Intelligent bracelet with hands with hands, do not wear hands as user
When the another hands of ring is in the state that can not go to operate Intelligent bracelet, user obviously cannot simply light screen, it is thus achieved that needs
Data.Therefore, eager a kind of screen of lighting is needed to go to meet user's without the mode of the auxiliary of an other hands
Demand.The method of current bracelet bright screen is generally adopted by detecting the flip angle of bracelet and goes to judge whether user sees the time
Demand, but, this determination methods judges to be inaccurate, and sometimes overturns screen several times and does not all work, and the most small dynamic
Make again screen bright screen always.Simultaneously as the custom of personal user, Intelligent bracelet may be worn in left hand and the right hand
Either hand on, when changing the hands worn every time, be required to user and go to arrange in detail that worn is left hand or the right hand, so
Go to change the algorithm lighting screen according to the situation of the right-hand man worn afterwards.As can be seen here, current bright screen determination methods is also deposited
Judge inaccurate defect, and need the defect that user resets when changing right-hand man.
Summary of the invention
It is desirable to provide a kind of Intelligent bracelet realizing turning wrist bright screen, so that user obtains function at needs
During data, light screen by wearing the realization of turning over of the arm of Intelligent bracelet thus obtain required information, by solely
Special algorithm can solve current bright screen and judge defect that is inaccurate and that need user to reset when changing right-hand man.
