Fig. 2 is the structural representation of the navigational system gesture command input judgment means of the embodiment of the invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
See also Fig. 1, be the process flow diagram of the gesture command input judging method of navigation system of the embodiment of the invention.The gesture command input judging method of navigation system of the embodiment of the invention comprises the steps:
Step S01: enter the gesture input pattern.
Step S02: the initial contact point of preserving user and guider.
Step S03: set the time interval of gesture command input, calculate the distance between this section period in the interior starting point moment and terminal point two contact points constantly.For example, the starting point of the time interval T of setting is T1 constantly, this moment user and guider contact point be P1 (X1, Y1); Terminal point is T2 constantly, and this moment, the contact point of user and guider was that (X2, Y2), the required calculated distance of navigational system is the distance L between a P1 and the some P2 to P2.
Wherein, this starting point moment contact point and terminal point moment contact point are the intermediate contact of this gesture command input.
In an embodiment of the present invention, for simple gesture command, also can be directly according to the initial contact point of this gesture command to the slope between the terminal point contact point with whether the operational order that conforms to is arranged in scope is judged navigational system, the input time that promptly need not set gesture command is at interval to preserve the intermediate contact of gesture command input, gesture command for complexity, therefore can there be a plurality of intermediate contacts, need to calculate the distance between intermediate contact and the adjacent last intermediate contact.
Step S04: among the determining step S03 calculated distance whether greater than distance predetermined in the navigational system, if, execution in step S06 then; If not, execution in step S05 then.
Step S05: give up the contact point between user and the guider constantly of terminal point among the step S03, and the position of writing down this contact point, go to step S03.
Step S06: preserve the contact point between terminal point moment user and the guider.
Step S07: the slope of the straight line of starting point moment contact point and terminal point contact point formation constantly among the calculation procedure S03, and preserve this slope.For the input that has a plurality of intermediate contacts, then calculate the straight slope that each intermediate contact and an adjacent last intermediate contact form respectively and preserve.
Step S08: whether the input of judging the user finishes, if then execution in step S09 if not, then jumps to step S03.In this step, judge the user be not moved in the time that benchmark that whether moving on the touch-screen finishes is being set in the touch point on the touch-screen for the user or the user broken off with touch-screen between contact.The user broken off and touch-screen between last contact point or the last contact point that in setting-up time, is not moved as the terminal point contact point.
Step S09: the initial contact point that calculates the input of this gesture command is to the distance between the terminal point contact point and judge the residing scope of this distance.
Step S10: calculate the slope residing scope of the initial contact point of this gesture command input to the straight line of terminal point contact point formation.
Step S11: judge according to drawing the residing scope of slope among the residing scope of distance between the initial contact point that draws among the step S09 and the terminal point contact point, the step S10 whether the operational order that conforms to is arranged in the navigational system, if have, execution in step S12 then, if do not have, execution in step S13 then.
Step S12: read the operational order and the execution that conform in the navigational system.
Step S13: judge whether the user needs to re-enter, if, then jump to step S01, if not, then withdraw from.
In an embodiment of the present invention, before step step S01, also comprise: the distance range and the slope range of in navigational system, storing the operation command correspondence in advance, the operational order that certain distance scope and slope range are corresponding different respectively, therefore, the slope that can judge the distance of input initial contact point of gesture command and terminal point contact point and form straight line whether in predetermined scope, thereby can carry out corresponding order.
