Difference, and when the time interval of current gesture and previous gesture is less than the first preset value, ignore current gesture；Illustratively,
One preset value is 1s；
Specifically, illustrating that user needs to repeat an operation, at this time when current gesture is identical with previous gesture
It does not need to judge the time interval before gesture twice, directly progress next step, and works as current gesture and previous gesture
When different, it is possible to the linking gesture before currently gesture is previous gesture and next gesture, so in order to guarantee gesture identification
Accuracy, need to judge the time interval size between current gesture and previous gesture at this time, if time interval is less than
One preset value (under normal circumstances, the interval time minimum value between the different gestures for controlling car-mounted terminal), it is determined that when
Preceding gesture is linking gesture, ignores gesture before deserving；If time interval is greater than the first preset value, current gesture is confirmed
It is not linking gesture, subsequent judgement then is executed to current gesture；
It should be noted that the step of extra gesture processing module executes, can be and judge in gesture judgment module for the first time

It is spaced between 1 to 2 second, if the time interval of a certain gesture and previous gesture is greater than 2 seconds, is identified as being hand for the first time
Gesture is then the linking gesture for not needed control action less than 1s.
Because gesture detection module is a template in mobile unit, and as equipment, necessarily have when obtaining gesture
Certain qualifications (such as gesture show in the speed of hand and position of gesture) (avoid are to guarantee the accurate of the gesture obtained
Other objects or biology pass through the screen of car-mounted terminal), in addition, because the driver of the affiliated vehicle of car-mounted terminal is not necessarily one
Individual, and the size of even one people its hand or shape are also not unalterable, so gesture detection module is being examined
For showing that the size of the hand of gesture can allow a preset range when surveying gesture, hand or object not in range are shown
Gesture or exercise void；
Therefore optional, referring to shown in Fig. 4, which further includes effective judgment module 35, effective judgment module 35
For gesture judgment module 32 for the first time judge current gesture that gesture detection module 31 detects whether be for the first time before gesture,
Whether the gesture that the information of the current gesture detected according to gesture detection module 31 judges that user shows meets preset rules, accords with
Close preset rules then confirm the gesture effectively and the judgement or identification of gesture for the first time, in vain then reacquire or prompting user after
It reacquires (alerting pattern includes but is not limited to voice, text)；Preset rules include at least the speed to the current gesture
With the regulation of position.
Because being integrated with multiple functions on car-mounted terminal, such as music player, navigation map, video player
Deng so there are multiple-working modes for car-mounted terminal, and corresponding gesture value volume and range of product is also different under each pattern

Whether the current gesture that disconnected gesture detection module 31 detects is effective under the current operation mode of mobile unit, effectively then extra
Whether gesture processing module is identical to current gesture and previous gesture to determine, after then reacquiring in vain or remind user
It reacquires；It should be noted that this deterministic process can be before gesture judgment module for the first time be to the judgement of gesture for the first time
Can be after the judgement of gesture for the first time, it can be in extra gesture processing module to current gesture and the whether identical progress of previous gesture
Can also after which, under the premise of not influencing judging result before determining, the execution priority of the step can not limit
