As shown in fig. 1, in an embodiment of the present invention, the present invention provides a method for alleviating motion sickness based on a user terminal, including the following steps:
s100: acquiring a motion state parameter of a user;
s200: judging the motion state type of the user according to the motion state parameters of the user;
s300: generating a dynamic identification image corresponding to the motion state type of the user;
s400: and displaying the dynamic identification image in the user terminal.
In the present invention, the user terminal may be a terminal such as a mobile phone of a user, a tablet computer, a notebook computer, etc., and the following description will take the mobile phone of the user as an example, but the present invention is not limited thereto.
Therefore, the motion state parameters of the user are detected through the step S100, and the dynamic identification image is changed on the user terminal through the steps S200 to S400 according to the motion state parameters of the user, so that the dynamic identification image is matched with the current motion state of the user to balance the visual perception and the body motion of the user, thereby effectively reducing the dizzy feeling of the user and achieving the purpose of relieving the motion sickness.
In the step S100, the user motion state parameter includes acceleration data of the user, and in the step S200, the motion state type of the user is determined according to the acceleration data of the user.
In this embodiment, the acquiring of the motion state parameters of the user in step S100 includes acquiring acceleration data of the user from an acceleration sensor disposed on the headset. The invention fully utilizes the characteristic that the relative position between the earphone and the inner ear is not changed, and under the scene, the direction of the earphone acceleration sensor is equal to the movement direction of the inner ear. After the acceleration sensor in the earphone acquires the acceleration data of the user, the acceleration data can be sent to the user terminal through the low-power-consumption Bluetooth or other communication modes.
Considering that in the journey, the user often can arrange the earphone and use when looking over user terminal, need not additionally to purchase the entity product and wear for the user, this embodiment is through placing acceleration sensor in the earphone in, relatively accords with the user habit that the user arranged the earphone to play the cell-phone in the journey, and the operation of being convenient for is repeatedly usable.
In this embodiment, the step S200 of determining the exercise status type of the user according to the exercise status parameter of the user includes the following steps:
determining the x1 axis direction of a first coordinate system according to the width direction of the user terminal in the initial state of the user;
and extracting an acceleration direction from the acceleration data, and judging whether the user accelerates leftwards or rightwards according to the projection direction of the acceleration direction on the x1 axis.
Specifically, when the x1 axis direction is determined, if the direction from left to right is the positive x1 axis direction, the user accelerates to the right if the projection direction of the acceleration direction on the x1 axis is the positive x1 axis direction, and if the projection direction of the acceleration direction on the x1 axis is the negative x1 axis direction, the user accelerates to the left. Similarly, if the x1 axis direction is determined to be a x1 axis square from the right to left direction, the user accelerates to the left if the projection direction of the acceleration direction on the x1 axis is pointing to the x1 axis square, and accelerates to the right if the projection direction of the acceleration direction on the x1 axis is pointing to the x1 axis negative direction.
Further, in step S300, generating a dynamic identification image corresponding to the motion state type of the user includes the following steps:
determining the z1 axis direction of a first coordinate system according to the length direction of the user terminal in the initial state of the user;
generating an identification image comprising a first identification and/or a second identification, wherein the first identification is positioned on the left side of a display screen of the user terminal, and the second identification is positioned on the right side of the display screen of the user terminal;
when the user accelerates to the left, the height of the first marker along the z1 axis direction is reduced and/or the height of the second marker along the z1 axis direction is increased in the identification image, so that the visual perception and the body movement of the user are balanced;
when the user moves to the right in an accelerated mode, the height of the first mark along the direction of the z1 axis is increased and/or the height of the second mark along the direction of the z1 axis is decreased in the identification image, and therefore the visual perception and the body movement of the user are balanced.
As shown in fig. 2 to 5, schematic diagrams of dynamic identification images of the user in different motion states in this embodiment are shown. In this embodiment, the first marker is a first cylinder, the second marker is a second cylinder, and a cylinder connecting section is provided between the first cylinder and the second cylinder. Specifically, in this embodiment, in the step S300, generating a dynamic identification image corresponding to the motion state type of the user includes the following steps:
determining the z1 axis direction of a first coordinate system according to the length direction of the user terminal in the initial state of the user;
generating an image comprising a first cylinder, a second cylinder and a cylinder connecting section, wherein the first cylinder is positioned on the left side of a display screen of the user terminal, the second cylinder is positioned on the right side of the display screen of the user terminal, and the cylinder connecting section is connected between the first cylinder and the second cylinder;
when the user moves to the left in an accelerated manner, the height of the first cylinder along the z1 axis in the identification image is lower than the height of the second cylinder along the z1 axis;
when the user moves to the right in an acceleration mode, the height of the first cylinder along the z1 axis in the identification image is higher than the height of the second cylinder along the z1 axis.
In this embodiment, the generating a dynamic identification image corresponding to the motion state type of the user further includes determining a length difference between the first cylinder and the second cylinder along the z1 axis direction according to an acceleration value in the acceleration data.
As shown in fig. 2 and 3, the dynamic identification image changes when the user accelerates horizontally to the right and horizontally to the left. As shown in fig. 2, when the user moves horizontally and accelerates to the right, the acceleration data of the user is obtained, and the acceleration value in the acceleration data is decomposed into g in the x1 axis direction x1 And z1 axis direction g z1 . Assuming that a thin sheet is taken at the bottom of the first column on the left side, when the liquid is stationary, the left and right forces are the same for the thin sheet, and the liquid density is ρ. The following formula is satisfied:
ρ*g z1 *h 1 ＝ρ*g z1 *h 2 +ρ*g x1 *L
wherein h is 1 Height of the first column, h 2 Is the height of the second column and L is the width of the display screen of the user terminal.
This can be deduced: Δ h = h 2 -h 1 ＝ρ*g x1 *L/(ρ*g z1 )＝L*g x1 /g z1
Therefore, when the user performs horizontal rightward acceleration movement, the height difference between the first cylinder and the second cylinder is Δ h, and the height variation value of the first cylinder is preferably the same as that of the second cylinder, so that the total length of the connection ends of the first cylinder, the second cylinder and the cylinders is constant, and a more realistic user movement simulation effect can be realized.
As shown in fig. 3, also, when the user accelerates horizontally to the left, the height difference of the first cylinder and the second cylinder satisfies the following formula:
Δh＝h 1 -h 2 ＝ρ*g x1 *L/(ρ*g z1 )＝L*g x1 /g z1
fig. 4 and 5 show the changing state of the dynamic identification image when the user is accelerated to lean to the right and when the user is accelerated to lean to the left. In this state, the user terminal tilts with the user, and after the user terminal tilts, the coordinate system of the user terminal moves along with the user terminal, so that the directions of the x2 axis and the z2 axis of the second coordinate system need to be determined according to the current width direction and the length direction of the user terminal in addition to the directions of the x1 axis and the z1 axis of the first coordinate system, and the direction of the z2 axis and the direction of the z1 axis form an included angle α. After the acceleration value is obtained, the acceleration value is decomposed into an acceleration value g in the x2 axis direction x2 And acceleration value g in z2 axis direction z2 。
As shown in fig. 4, when the user is accelerated to tilt to the right, the user terminal tilts to the right with the user. The height h of the first column along the z1 axis 1 Is still higher than the height h of the second column along the z1 axis 2 In (1). At this time, the upper surface of the second cylinder is selected as a reference surface O, for which the stress is balanced,the following conditions need to be satisfied:
Δh*ρ*G+L*ρ*G*sinα＝L*ρ*g x2
Δh＝h 1 -h 2 ＝L*g x2 /G-L*sinα
wherein G is the acceleration of gravity.
As shown in fig. 5, likewise, when the user is accelerated to tilt to the left, the user terminal is tilted to the left with the user. The height h of the first column along the z1 axis 1 Is lower than the height h of the second cylinder along the z1 axis 2 In (3). At this time, the upper surface of the first column is selected as a reference plane O, and for the reference plane O, the following conditions need to be satisfied for the stress balance:
Δh*ρ*G+L*ρ*G*sinα＝L*ρ*g x2
Δh＝h 2 -h 1 ＝L*g x2 /G-L*sinα
the same holds true for the cases of fig. 2 and 3. When the user accelerates horizontally to the right or left in fig. 2 and 3, the second coordinate system coincides with the first coordinate system, gx 2 And gx 1 Same, α is zero, acceleration g in z1 axis z1 I.e. equal to the gravitational acceleration G.
Therefore, in this embodiment, the determining the length difference of the first cylinder and the second cylinder along the z1 axis direction according to the acceleration value in the acceleration data includes the following steps:
respectively determining the x2 axis direction and the z2 axis direction of a second coordinate system according to the width direction and the length direction of the current user terminal;
determining an included angle alpha between the direction of the z2 axis and the direction of the z1 axis;
decomposing the acceleration value in the acceleration data into an acceleration value g in the x2 axis direction x2 ；
Determining a difference in length of the first cylinder and the second cylinder along the z1 axis according to the following formula:
Δh＝L*g x2 /G-L*sinα
and Δ h is a length difference of the first cylinder and the second cylinder along the z1 axis direction, and L is a width of a display screen of the user terminal.
In this embodiment, it is preferable that a length variation value of the first cylinder in the z2 axis direction is the same as a length variation value of the second cylinder in the z2 axis direction. Thereby make first cylinder, cylinder linkage segment and the whole simulation of second cylinder a liquid column that can the horizontal slip, and the stock solution total amount of liquid column is unchangeable to the visual sensation and the actual body motion that the user sees on user terminal are balanced better, reach the purpose of alleviating motion sickness.
