Resultant motion condition (step S520).In this, the moving condition is to be judged according to the metric data of acceleration transducer 240.
Through the metric data of acceleration transducer 240, sensing arm motion (such as arm is lifted or put down), wrist upset can be used to
The athletic performance of arm and/or wrist.Judge that user 400 makes viewing hand according to the metric data of acceleration transducer 240
During the action of table 200, then meet moving condition.
If first determining ranging condition sets up (step S510), further judge whether moving condition sets up (step
S530), if this two conditions are set up, S551 is just entered step, opens backlight.If it is determined that moving condition is invalid, then into one
Whether step judges user 400 in actively opening backlight (step S552) in the scheduled time.If so, then according to acceleration at that time
The metric data modification moving condition (step S571) of sensor 240, if it is not, being then not turned on backlight (step S572).Accordingly, may be used
The effect of reaching self-teaching, allows wrist-watch 200 to open the opportunity of backlight, the more and more use habit close to user 400.
Similarly, judge that moving condition sets up (step S520) if first determining, further judge that ranging condition is
It is no to set up (step S540).If this two conditions are set up, S561 is just entered step, opens backlight.If it is determined that ranging condition is not
Set up, then further judge user 400 whether in actively opening backlight (step S562) in the scheduled time.If so, then basis
Signal strength or distance modification moving condition (step S581) at that time, if it is not, being then not turned on backlight (step S582).Summarize and
Say, if it is incongruent be ranging condition if correct ranging condition, if incongruent is moving condition correction motion condition.
