Referring to Fig. 1, an embodiment of the present invention provides a display control method applied to an electronic torch. The display control method includes the steps:

Step S101: Display a first flame pattern on the display screen.

Referring to FIG. 2, the electronic torch 10 includes a display screen 101 and a handle 102. The display screen 101 is used to display a flame pattern to simulate the flame of a traditional torch. The handle 102 is connected to the display screen 101 for holding by the user, so that the user can hold the electronic torch 10 through the handle 102. When the display screen 101 of the electronic torch 10 is activated, the first flame pattern is displayed on the display screen 101.

Step S102: Detect the movement information of the electronic torch.

The electronic torch 10 is also provided with a detection unit 103, which is installed on the handle 102 or integrated in the display screen 101 for acquiring the movement information of the electronic torch 10. The detection unit 103 may be a speed sensor or an acceleration sensor.

Step S103: Determine whether the movement state of the electronic torch has changed according to the detected movement information.

The motion state of the electronic torch 10 refers to the state of the motion speed relative to the ground when the torch is in motion. The motion information of the electronic torch 10 includes acceleration, and the acceleration includes the magnitude and direction of the acceleration.

In this embodiment, the electronic torch 10 starts to move from a stationary state as an example for description. The speed of the electronic torch 10 can be obtained by detecting the acceleration of the electronic torch 10 by the detection unit 103, that is, by detecting the acceleration of the electronic torch 10 It can be known whether the movement state of the electronic torch 10 has changed.

Specifically, the detection unit 103 is an acceleration sensor, and the acceleration sensor is used to obtain the acceleration of the electronic torch 10.

Please refer to FIG. 3. Specifically, step S103 includes:

Step S1031: Determine whether the electronic torch performs a variable speed motion according to the acceleration.

When the acceleration is greater than zero, the electronic torch 10 is determined to be accelerating. When the acceleration is less than zero, the electronic torch 10 is determined to be decelerating. When the acceleration is equal to zero, it is determined that the electronic torch 10 is moving at a constant speed or the electronic torch 10 is stationary. Wherein, when the electronic torch 10 performs a variable speed movement such as an acceleration movement or a deceleration movement, it is determined that the movement state of the electronic torch 10 has changed.

Step S1032: When the electronic torch moves at a variable speed, it is determined that the movement state of the electronic torch has changed.

Among them, the movement state refers to the state of the movement speed relative to the ground when the torch is moving. When the electronic torch 10 performs a variable speed movement such as acceleration or deceleration, the speed and/or direction of the electronic torch 10 changes, that is, it is determined The movement state of the electronic torch 10 changes.

When it is determined that the electronic torch 10 is moving at a constant speed, it is determined that the motion state of the electronic torch 10 has not changed.

Step S104: When the motion state of the electronic torch changes, control the display screen to switch the displayed first flame pattern to a second flame pattern according to the motion information, and the second flame pattern is the same as the second flame pattern. The first flame pattern is different.

The first flame pattern is the flame pattern displayed when the electronic torch 10 is at rest. The acceleration includes the magnitude and direction of acceleration, and the direction of acceleration includes the first acceleration direction and the second acceleration direction. The first acceleration direction and the second acceleration direction are opposite to each other.

When the electronic torch 10 starts to move from a standstill, the acceleration direction of the electronic torch 10 is the speed direction of the electronic torch 10.

Please refer to FIG. 4A. Specifically, step S104 includes:

Step S1041: Calculate the amount of tilt according to the magnitude and direction of acceleration.

In some embodiments, the amount of inclination is calculated according to the magnitude of acceleration and the direction of acceleration, which specifically includes, preset the corresponding relationship between the magnitude of acceleration, direction of acceleration, and amount of inclination, and calculate the corresponding amount of inclination by obtaining the magnitude and direction of acceleration. .

In some embodiments, when the acceleration direction is the first acceleration direction, the inclination amount is calculated according to a first formula, where the first formula is: θ=(2θ _m )/π*arctan|a |, where θ is used to indicate the amount of tilt, θ≥0, a is used to indicate acceleration, and θ _m is a preset value, as shown in Figure 4B.

When the acceleration direction is the second acceleration direction, the tilt amount is calculated according to a second formula, where the second formula is: θ=-(2θ _m )/π*arctan|a|, where θ It is used to indicate the amount of tilt, θ<0, a is used to indicate acceleration, and θ _m is a preset value, as shown in Figure 4B.

Step S1042: Obtain a flame pattern corresponding to the tilt amount as the second flame pattern according to the corresponding relationship between the tilt amount and the preset tilt amount and flame pattern.

The corresponding relationship between the inclination amount and the flame pattern is preset, and after the inclination amount is calculated by obtaining the magnitude and direction of acceleration, the flame pattern corresponding to the inclination amount is obtained as the second flame pattern.

For example, when the acceleration direction is the first acceleration direction and the acceleration magnitude is a1, that is, when the electronic torch 10 accelerates in the first acceleration direction with the acceleration a1, the corresponding tilt is calculated as θ1, and the flame pattern corresponding to θ1 As shown in FIG. 5A, the flame pattern is shifted in the direction opposite to the acceleration, and the flame pattern corresponding to the inclination amount θ1 is used as the second flame pattern.

When the acceleration direction is the first acceleration direction, the acceleration magnitude is a2, and a2 is greater than a1, the calculated inclination amount is θ2, and the flame pattern corresponding to θ2 is shown in Figure 5B. The flame pattern shifts in the direction opposite to the acceleration , The flame pattern corresponding to the inclination amount θ2 is used as the second flame pattern. And when the acceleration magnitude is a2, the tilt amount of the second flame pattern in the second acceleration direction is greater than the tilt amount of the second flame pattern in the second acceleration direction when the acceleration magnitude is a1.

When the acceleration direction is the second acceleration direction and the acceleration magnitude is a3, that is, when the electronic torch 10 is accelerating on the second acceleration square, the calculated inclination amount is θ3, and the flame pattern corresponding to θ3 is shown in Figure 5C , The flame pattern shifts to the direction opposite to the acceleration, and the flame pattern corresponding to the inclination amount θ3 is used as the second flame pattern.

When the acceleration direction is the second acceleration direction, the acceleration magnitude is a4, and |a4| is greater than |a3|, the calculated inclination is θ4, and the flame pattern corresponding to θ4 is shown in Figure 5D. The flame pattern is opposite to the acceleration The direction is shifted, and the flame pattern corresponding to the tilt amount θ4 is used as the second flame pattern. And when the acceleration magnitude is a4, the tilt amount of the second flame pattern in the first acceleration direction is greater than the tilt amount of the second flame pattern in the first acceleration direction when the acceleration magnitude is a3.

That is, the greater the absolute value of the acceleration, the greater the inclination of the second flame pattern in the direction opposite to the acceleration, that is, the greater the deviation of the second flame pattern from the first flame pattern.

Step S1043: Display the acquired second flame pattern.

Display the second flame pattern on the display screen to replace the first flame pattern.

Referring to FIG. 6, in some embodiments, after displaying the second flame pattern, the display control method further includes:

Step S105: Detect whether the acceleration changes.

When the display screen 101 of the electronic torch 10 displays the second flame pattern, the detection unit 103 detects whether the acceleration of the electronic torch 10 changes.

Step S106: When the acceleration changes, control the display screen to switch the displayed second flame pattern to the third flame pattern, and the third flame pattern is different from the second flame pattern.

Referring to FIG. 7A, in some embodiments, step S106 includes:

Step S1061: When the acceleration changes, obtain the acceleration magnitude and acceleration direction of the acceleration.

When the acceleration changes, the direction of acceleration is obtained to determine whether the electronic torch 10 is accelerating or decelerating. At the same time, the magnitude of the acceleration is obtained to determine the amount of speed change per unit time when the electronic torch 10 is accelerating or decelerating. .

Step S1062: Calculate the tilt compensation amount according to the corresponding relationship between the acceleration magnitude, the acceleration direction and the preset acceleration magnitude, the acceleration direction and the tilt compensation amount.

The corresponding relationship between the acceleration magnitude, acceleration direction, and tilt compensation amount is preset, and the corresponding tilt compensation amount can be calculated by obtaining the acceleration magnitude and acceleration direction.

Step S1063: Obtain a third flame pattern according to the tilt compensation amount and the corresponding relationship between the preset tilt compensation amount and the third flame pattern.

The corresponding relationship between the tilt compensation amount and the third flame pattern is preset, and the corresponding third flame pattern is obtained by obtaining the tilt compensation amount.

Step S1064: controlling the display screen to switch the displayed second flame pattern to the third flame pattern.

Specifically, the movement information of the electronic torch 10 also includes speed, where the speed includes the magnitude and direction of the speed. The speed direction is the direction of movement of the electronic torch 10. When the speed direction of the electronic torch 10 is opposite to the acceleration direction, the electronic torch 10 10 After the second flame pattern is displayed on the display screen 101, the electronic torch 10 makes a decelerating motion, and the display position of the third flame pattern is between the display position of the second flame pattern and the display position of the first flame pattern, as shown in FIG. 7B .
