The traditional pointer is acted by the driving force of a motor and has a movement tendency; meanwhile, as a real object, the traditional pointer has inertia and can be subjected to resistance in the moving process, so that the pointer has a tendency of being static.

Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a pointer display method according to an embodiment of the present application. The pointer display method provided by the embodiment of the application can be suitable for the situation of displaying the pointer. Typically, the embodiment of the present application is applied to a case of controlling the motion display of the virtual pointer. The method can be specifically executed by a pointer display device, the device can be realized by software and/or hardware, the device can be integrated into electronic equipment capable of realizing the pointer display method, and the electronic equipment can be a computer, a mobile phone, a tablet computer, wearable equipment and the like. Referring to fig. 1, the method of the embodiment of the present application specifically includes:
and S110, if the position of the virtual pointer is detected to need to be updated, controlling the virtual pointer to perform accelerated motion based on the first target acceleration.
The virtual pointer may be a non-mechanical pointer displayed on an electronic display screen, such as a pointer drawn on the display screen. The electronic display screen may be a dashboard or a central control screen in the vehicle. The position of the virtual pointer may represent the position of the virtual pointer when pointing on the dial.
In the embodiment of the present application, the virtual pointer makes a circular motion, and in order to describe the motion condition of the virtual pointer, the acceleration of the circular motion of the virtual pointer is decomposed, and if the rotation trajectory of the virtual pointer is stretched into a straight line, the acceleration of the virtual pointer making the straight line motion is the acceleration along the tangential direction of the rotation trajectory, so the accelerations in the embodiment of the present application all refer to the acceleration along the tangential direction of the rotation trajectory of the virtual pointer. The first target acceleration is an acceleration in a tangential direction at a point on the outer end of the virtual pointer on the rotation locus of the outer end of the virtual pointer, and as shown in fig. 2, if the virtual pointer moves from the position of the indication 40 to the position of the indication 60, the first target acceleration is an acceleration noted in fig. 2 at the position indicated by the virtual pointer at this time.
If the parameter indicated by the virtual pointer changes, the position of the virtual pointer is determined to need updating, for example, if the vehicle speed is increased from 40 km/h to 80 km/h, the virtual pointer is determined to need updating when the current position indicating 40 km/h is changed to the position indicating 80 km/h. It is detected whether the position of the virtual pointer needs to be updated, that is, whether the index value indicated by the virtual pointer changes. And if the index value is not changed, determining that the position of the virtual pointer does not need to be updated.
For example, the electronic device detects in real time whether the index value indicated by the virtual pointer changes, that is, whether the position of the virtual pointer needs to be updated, and if the position of the virtual pointer does not need to be updated, the electronic device does not need to control the virtual pointer to move. And if the position of the virtual pointer needs to be updated, determining a first target acceleration of the virtual pointer for moving, and controlling the virtual pointer to move based on the first target acceleration.
And S120, if the moved distance of the virtual pointer is inconsistent with the target movement distance and the current speed reaches a preset target speed, determining a second target acceleration according to the preset target speed and the distance difference between the target movement distance and the moved distance.
The moved distance may be the length of the trajectory traveled by the virtual pointer from the initial position to the current time when the virtual pointer performs the accelerated motion, and the target moving distance may be the length of the trajectory traveled by the virtual pointer from the initial position to the target position. The preset target speed is a preset speed peak value, and the accelerated motion of the virtual pointer reaches the speed peak value.
Illustratively, if it is detected that the moved distance of the virtual pointer is inconsistent with the target movement distance, it is determined that the virtual pointer has not yet reached the target position and still needs to be moved, it is determined whether the current speed of the virtual pointer reaches a preset target speed, if the current speed has reached the preset target speed, it is determined that the virtual pointer has reached a preset speed peak, the movement speed reaches a higher value in the current middle movement stage, has a faster response speed, deceleration is subsequently required to achieve the appearance of a transitional state before reaching the target position, with a smooth transition to the target position, and, therefore, and determining a second target acceleration according to the preset target speed and the distance difference between the target movement distance and the moved distance, namely the residual movement distance, wherein the second target acceleration is actually a negative value and is used for controlling the virtual pointer to perform deceleration movement.
The beneficial effects of the above scheme are that, can make the virtual pointer accelerate smoothly in the early stage, show transition state for the user, accelerate to preset target speed in the middle stage, reach the speed peak value, realize high-speed motion for response time, and after reaching preset target speed, confirm the virtual pointer of second target acceleration control speed reduction, smooth transition to the target location shows transition state for the user, improves user experience.
And S130, controlling the virtual pointer to perform deceleration movement based on the second target acceleration until the moved distance is consistent with the target movement distance or the virtual pointer performs deceleration movement until the virtual pointer stops.
Illustratively, the deceleration movement of the virtual pointer is controlled based on the second target acceleration, the movement state of the virtual pointer is detected in real time during the movement, and if the moved distance of the virtual pointer is consistent with the target movement distance, namely, the virtual pointer is moved to the target position, the virtual pointer is determined to have moved to the target position. Or decelerating the movement to a stop, since the second target acceleration of the virtual pointer is determined according to a distance difference between the moved distance and the target movement distance, when the virtual pointer decelerates to the stop, the virtual pointer is determined to move to the target position, and when the virtual pointer moves to the target position, the virtual pointer may be controlled to stop moving.
In the embodiment of the application, the virtual pointer performs deceleration movement at the later stage of movement, and when the virtual pointer moves to the adjacent target position, the speed is decelerated to be close to zero, so that the effect of smoothly moving to the target position can be shown, a transition state is embodied, and the user experience is improved.
In the embodiment of the application, if it is detected that the position of the virtual pointer needs to be updated, the virtual pointer is controlled to perform accelerated motion based on the first target acceleration, so that the virtual pointer can smoothly move in the previous motion and gradually accelerate to achieve a faster response in the middle motion, if the moved distance of the virtual pointer is inconsistent with the target moving distance and the current speed reaches the preset target speed, a second target acceleration is determined according to the preset target speed and the distance difference between the target moving distance and the moved distance, the virtual pointer is controlled to perform decelerated motion based on the second target acceleration until the moved distance is consistent with the target moving distance or the virtual pointer decelerates to stop, so that the virtual pointer decelerates after the middle acceleration and can resume the smooth motion in the later motion, the transition state is displayed for the user, the user feels the gradual change state of the virtual pointer from the initial position to the target position, and the response time can be improved due to medium-term acceleration.
Fig. 3 is a flowchart of a pointer display method according to another embodiment of the present application. For further optimization of the embodiments, details which are not described in detail in the embodiments of the present application are described in the embodiments. Referring to fig. 3, a pointer display method provided in an embodiment of the present application may include:
s210, if the position of the virtual pointer is detected to need to be updated, determining the target position and the current position of the virtual pointer.
For example, if it is detected that the index value indicated by the virtual pointer changes, that is, the position of the virtual pointer needs to be updated, the current position of the virtual pointer and the target position that needs to be moved need to be determined. For example, if the initial vehicle speed is 20 km/h and the current vehicle speed is adjusted to 40 km/h, the current position of the virtual pointer is a position indicating 20 km/h and the target position is a position indicating 40 km/h before the virtual pointer is adjusted.
S220, determining the target movement distance of the virtual pointer according to the target position and the current position.
For example, according to the target position and the current position, the target movement distance of the virtual pointer, that is, the virtual pointer moves from the current position to the target position, and the outer end of the virtual pointer traverses the length of the trajectory, may specifically be calculated according to the central angle of the virtual pointer rotated from the current position to the target position and the length of the virtual pointer.
And S230, determining a first target acceleration associated with the target movement distance based on the association relationship between the movement distance and the acceleration.
The incidence relation between the movement distance and the acceleration can be determined according to actual conditions, so that the movement speed of the virtual pointer is controlled through the incidence relation between the movement distance and the acceleration, and the response time of the virtual pointer is further controlled. For example, the movement distance may be set in proportion to the acceleration, and the larger the movement distance, the larger the acceleration, and the smaller the movement distance, the smaller the acceleration. According to the association relationship between the movement distance and the acceleration, a first target acceleration associated with the target movement distance can be determined, so that the virtual pointer is controlled to perform accelerated movement according to the first target acceleration.
And S240, controlling the virtual pointer to perform accelerated motion based on the first target acceleration.
And S250, if the moved distance of the virtual pointer is not consistent with the target movement distance and the current speed reaches a preset target speed, determining a second target acceleration according to the preset target speed and the distance difference between the target movement distance and the moved distance.
In an embodiment of the present application, the method further includes: determining the preset speed according to a preset distance and the acceleration associated with the movement distance; wherein the preset distance is smaller than the movement distance; and determining the association relation among the movement distance, the acceleration and the preset speed. The process of determining the preset target speed comprises the following steps: and determining a preset target speed associated with the target movement distance based on the association relation among the movement distance, the acceleration and the preset speed.
Exemplary, predeterminedThe preset distance and the acceleration are determined, the preset speed can be determined, and then the association relation among the movement distance, the acceleration and the preset speed is established. The preset speed is a speed peak value reached by the virtual pointer when the moving distance is the preset distance and the linear uniform acceleration movement is carried out based on the acceleration under the condition that the initial speed of the virtual pointer is zero. Specifically, it can be calculated according to the following formula: v. of2Where v is a predetermined velocity, a is an acceleration, and S is a predetermined distance, where the predetermined distance may be selected as a fraction of the movement distance, e.g., one-third, one-half, etc. of the movement distance. In this application embodiment, the preset distance may be set to be half of the movement distance, that is, when the virtual pointer is controlled to move to half of the movement distance with the acceleration, the speed reaches the preset speed, that is, the speed peak value, so that the virtual pointer moves at a gentle speed in the early stage and the later stage, the transition effect is realized, the middle stage moves quickly, and the response time is shortened. In the actual application process, after the target movement distance is determined, the preset target speed associated with the target movement distance is determined according to the association relation among the movement distance, the acceleration and the preset speed, and therefore the speed peak value to which the virtual pointer needs to move is determined.
And S260, controlling the virtual pointer to perform deceleration movement based on the second target acceleration until the moved distance is consistent with the target movement distance or the virtual pointer performs deceleration movement until the virtual pointer stops.
In an embodiment of the present application, the method further includes: detecting whether the moved distance of the virtual pointer is consistent with the target movement distance or not according to a preset frequency; if the virtual pointer is consistent with the preset virtual pointer, controlling the virtual pointer to stop moving; and if not, controlling the virtual pointer to continue moving.
Illustratively, the moving distance of the virtual pointer is detected according to a preset frequency, and whether the virtual pointer moves to the target position is determined. And if the virtual pointer does not move to the target position, controlling the virtual pointer to continue moving according to the movement scheme until the condition that the virtual pointer stops moving is met.
In the embodiment of the application, whether the child needs to be updated or not is detected through the virtual pointer in real time, when the child needs to be updated, the target movement distance of the virtual pointer is determined, then the first target acceleration is determined according to the target movement distance, the virtual pointer is controlled to move in an accelerated mode based on the first target acceleration, therefore the position of the virtual pointer is updated, and the updated index value is indicated.
In this embodiment, in S250, if the moved distance of the virtual pointer is not consistent with the target moving distance and the current speed reaches the preset target speed, the virtual pointer is controlled to move at a constant speed at the preset target speed for a preset time, and then the second target acceleration is determined according to the preset target speed and the distance difference between the target moving distance and the moved distance.
Illustratively, the virtual pointer is controlled to move at a first target acceleration until the speed of the virtual pointer reaches a preset target speed, and then the virtual pointer is controlled to move at a constant speed at the preset target speed, so as to improve the response speed, shorten the movement time in the middle period of movement, and after the constant speed reaches the preset time, in the later period of movement, a second target acceleration is determined according to the preset target speed and the distance difference between the target movement distance and the moved distance, and the virtual pointer is controlled to move at the second target acceleration, so that the virtual pointer moves smoothly in the later period, and a transition state is shown.
