Due to the change of the acceleration direction during the screen change process, the existing screen recognition process is prone to error in the screen orientation, which further causes the corresponding operation instructions to be confused, greatly reducing the user experience.

Based on the above problems, the present invention provides a terminal screen recognition method.

Referring to FIG. 4, FIG. 4 is a schematic flowchart diagram of a first embodiment of a method for identifying a screen of a terminal according to the present invention.

In this embodiment, the terminal screen recognition method includes the following steps:

Step S10, detecting an acceleration in a preset direction of the terminal, and recording an initial acceleration when the terminal is stable;

The preset direction may be set according to the direction of the screen to be recognized by the terminal, for example, the lower left corner of the terminal screen is taken as the origin, and the right direction along the width direction of the terminal screen is used as the positive direction of the preset direction. Then, it can be used to recognize the gesture action of the left or right squat; or the forward direction along the length direction of the terminal screen as the preset direction can be used to recognize the gesture action of the upper or lower jaw. It should be understood that the acceleration described in the present invention is an acceleration in the predetermined direction, which is positive when the acceleration is the same as the preset direction, and negative when the acceleration is opposite to the preset direction.

Preferably, the acceleration in the preset direction of the terminal may be detected at a preset time interval (for example, every 100 ms), and the acceleration when the terminal is stable is recorded as the initial acceleration. The initial acceleration is an average acceleration in the preset direction when the terminal acceleration is stable, and is used to calculate an acceleration change based on the initial acceleration calculation acceleration variation.

Preferably, the acceleration of the terminal can be detected by an acceleration sensor. The acceleration sensor may be a pendulum integral acceleration sensor, a vibration beam acceleration sensor, a capacitive acceleration sensor, a piezoresistive acceleration sensor, a thermocouple acceleration sensor, a resonant acceleration sensor, a piezoelectric acceleration sensor or an optical waveguide acceleration sensor. One or more of the sensors. Preferably, the acceleration component of the terminal on the x-axis, the y-axis, and the z-axis can be detected by a G-sensor (Gravity-sensor).

Preferably, the detected real-time acceleration data and the initial acceleration may be saved in a memory for querying or reading and writing data. The memory may include at least one type of storage medium including a flash memory, a hard disk, a multimedia card, a card type memory (eg, SD) Or DX memory, etc.), random access memory (RAM), static random access memory (SRAM), read only memory (ROM), electrically erasable programmable read only memory (EEPROM) , Programmable Read Only Memory (PROM), magnetic memory, disk, optical disk, etc.

Step S20, determining a screen time according to the detected acceleration change, and acquiring an acceleration in the screen time;

When the acceleration fluctuation of the terminal is detected to exceed a preset threshold, determining that the screen starts; when detecting that the acceleration of the terminal is stable to the initial acceleration, determining that the screen is over, determining the screen time, and obtaining the The acceleration in the screen time is described.

Alternatively, when the acceleration change twice before and after detecting the preset direction exceeds the preset range, the start of the screen may be determined; when the preset direction is detected, the acceleration changes twice before and after are within the preset range At the end, it is determined that the screen is over, the screen time is determined, and the acceleration in the screen time is obtained.

Step S30, determining a maximum acceleration change amount in combination with the acquired acceleration and the initial acceleration;

The acceleration change amount is determined according to the acquired acceleration time in the screen time and the recorded initial acceleration, and the absolute value of the acceleration change amount is determined, and the acceleration change amount having the largest absolute value is used as the maximum acceleration change amount. The positive and negative of the maximum acceleration change amount is related to the initial acceleration, and reflects the change of the acceleration in the screen time from the initial acceleration. Seen from the acceleration waveform, the maximum acceleration change is the peak or valley point with the largest amplitude during the screen time. When the point with the largest amplitude is the peak, the direction is positive, and when the point with the largest amplitude is the valley When the direction is negative.

When it is recognized that the user action is left-handed, the TV is switched to the previous channel. When the user action is recognized as the right-hand, the TV is switched to the next. Channel.

In this embodiment, the screen time is determined according to the acceleration change characteristic when the screen is screened, and the maximum acceleration change amount is determined according to the initial acceleration when the terminal is stable and the acceleration acquired during the screen time, and the maximum acceleration change amount during the screen capture period Positive and negative to determine the direction of the screen, effectively avoiding the misidentification caused by the change of the acceleration direction during the screen, improving the accuracy of the terminal screen recognition, and greatly improving the user experience.

Step S42, if the maximum acceleration change amount is positive, determining that the screen direction is the preset direction;

Step S43, if the maximum acceleration change amount is negative, it is determined that the screen direction is the reverse direction of the preset direction.

When the maximum acceleration change amount is determined, determining whether the maximum acceleration change amount is positive or negative; if the maximum acceleration change amount is positive, determining that the 甩 screen direction is the preset direction; if the maximum acceleration change amount is Negative, it is determined that the 甩 screen direction is the opposite direction of the preset direction. For example, the lower left corner of the terminal screen is used as an origin, and the right direction along the width direction of the terminal screen is used as the positive direction of the preset direction, and when the maximum acceleration change amount is positive, it is determined as the right 甩; When the maximum acceleration change amount is negative, it is determined to be left 甩.

In this embodiment, the direction of the screen is determined by the positive and negative of the maximum acceleration change amount during the screen clamping. If the maximum acceleration change amount is positive, it is determined that the screen direction is the preset direction; if the maximum acceleration change amount If it is negative, it is determined that the screen direction is the opposite direction of the preset direction. It effectively avoids the misidentification caused by the change of the acceleration direction during the screen pressing process, improves the accuracy of the terminal screen recognition, and greatly improves the user experience.
