Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
See also shown in Figure 1ly, Fig. 1 is system principle diagram of the present invention.The present invention is to provide a kind of portable terminal intelligence cursor control system and method, be mainly used in solving present big screen intelligent mobile phone and need pass through the both hands compounding practice, and the problem that can't use one hand to operate.
Wherein this system includes three alignment sensors, microprocessor, CPU, trigger, cursor locating module, display module and display screen, described three alignment sensors comprise 3-axis acceleration sensor, three magnetometric sensors and three-axis gyroscope transducer, corresponding the changing value of displacement, rotation direction and the angular speed of mobile phone in the space are responded to; Described microprocessor is connected with three alignment sensors, is used for obtaining the spatial orientation informations such as displacement, rotation direction and angular speed of mobile phone, and sends to CPU; CPU is connected with the cursor locating module, be used for that above-mentioned spatial orientation information sent to the cursor locating module and centered by the display screen center basic point position, by display module cursor is shown at display screen simultaneously.
Trigger 3-axis acceleration sensor by touching the portable terminal optional position, 3-axis acceleration sensor detects the mobile phone acceleration change in displacement value of moment, and feeds back to microprocessor.
Native system utilizes the 3-axis acceleration sensor on the mobile phone, three magnetometric sensors, the three-axis gyroscope transducer is realized the nine spool location of mobile phone in the space, adopt multisensor collaborative work principle, thereby the recognition data scope is expanded to the direction that X, Y, Z three-dimensional can accurately feed back to the rotation of mobile phone in the space, angular speed, the variation of displacement.Cursor locating module in the mobile phone can be judged mobile change direction and the speed of the cursor on the screen according to the data that mobile phone gets access to, when the user rotates mobile phone to corresponding direction, cursor on the mobile phone screen also can move along corresponding direction, when cursor is docked to the icon of certain application program, only need the light finger hitter's machine optional position with adept machine, comprise back cover, acceleration transducer detects the mobile phone acceleration change in displacement value of moment, realizes choosing function.
Wherein native system concrete operations mode is as follows: at first press power key and wake mobile phone up, 3-axis acceleration sensor, three magnetometric sensors, the orientation of three-axis gyroscope transducer detection of handset in the space, and be the center position that reference coordinate is positioned at the cursor on the screen display screen with the orientation of current phone in the space.This mainly is because at every turn when waking mobile phone up, the attitude of adept machine is all different, but no matter how the orientation in the space of mobile phone changes when waking up, all the coordinate that gets access to transducer positions a cursor over the positive center of screen as the reference coordinate, and after this rotation direction of mobile phone will be the movement that basic point is controlled the cursor on the mobile phone screen with the orientation of this reference coordinate all.
When the user tilts mobile phone up and down, multisensor will detect the variation of mobile phone in the space, and the reference frame of setting up when waking mobile phone up is made as cursor the side-play amount that changes the relative distance that moves up and down at screen as basic point, mobile phone is to the certain angle of any direction deflection, and cursor moves corresponding distance to corresponding direction on screen.When cursor moved on the icon of corresponding application program, with light finger hitter machine, acceleration transducer detected the mobile phone acceleration change in displacement value of moment, realizes choosing function.And if when realizing that mobile phone scroll-up/down and left and right sides page turning are rolled, only need be with mobile phone along up and down or the relative initial position of left and right directions when waking mobile phone up (press power key FUSION WITH MULTISENSOR DETECTION to the orientation of mobile phone in three dimensions) when tilting angle certain (be 30 degree as default), gyro sensor will be measured object at the angular speed in space or angle range variable quantity and initial position space relatively, if less than 30 degree, the angular movement that cursor can tilt in the screen upper edge, if greater than 30 degree, then along the angle that the tilts page turning of rolling.
More than be the explanation to portable terminal intelligence cursor control system of the present invention, be further described below in conjunction with 2 pairs of portable terminal intelligence cursor control methods of the present invention of accompanying drawing.
See also shown in Figure 2ly, Fig. 2 is operation principle flow chart of the present invention.The present invention also provides a kind of portable terminal intelligence cursor control method, and it comprises that specifically step is as follows:
