Based on the hardware architecture of the motion sensing game device based on the hand waving motion, the embodiment of the motion sensing game method based on the hand waving motion is provided. The invention discloses a somatosensory game method based on a waving action, which aims to realize nonlinear movement of a game object and promote game experience of a user.

Referring to fig. 2, fig. 2 is a diagram of an embodiment of a motion-based motion-sensing game method according to the present invention, the motion-based motion-sensing game method includes the following steps:

s10, after the motion sensing game is started, acquiring acceleration data in the horizontal direction or the vertical direction from the bound motion sensing equipment.

Wherein the motion sensing game is a motion sensing game associated with a waving motion that requires a player to play the waving motion with a motion sensing device to develop the game. Through the somatosensory game, a player can make a game character swing an object such as a weapon, a racket and the like to perform corresponding actions such as attack, batting and the like. In this way, the player can more realistically feel the fun of swiping the game.

Illustratively, a fruit-cutting game is a classical somatosensory game associated with a waving motion.

The somatosensory game can be a local application program, an applet or a web page application based on HTML5, and the like. Specifically, the somatosensory game is run on a terminal, which may be a desktop computer, a notebook computer, a game host, a portable game host, a smart phone, a tablet computer, a smart watch, a smart television, and the like.

The motion sensing device refers to a device capable of detecting motion sensing data of a player, and generally, the motion sensing device is configured to include a six-axis IMU sensor including a three-axis accelerometer and a three-axis gyroscope, which detects motion sensing data of a player by detecting a change in three-axis acceleration and a change in three-axis angular velocity of the player.

In the technical scheme of the application, acceleration data acquired by the terminal from the somatosensory equipment are triaxial acceleration data directly acquired by an accelerometer (also called a gravity sensor). The three-axis acceleration data are x-axis acceleration data, y-axis acceleration data and z-axis acceleration data, respectively. The x-axis is the acceleration axis in the front-back direction, the z-axis is the acceleration axis in the vertical direction, and the y-axis is the acceleration axis in the left-right direction. Thus, even if the motion sensing device has only the gravity sensor, the input of the waving command can be completed through the motion sensing action.

Optionally, the somatosensory device is configured to be wearable in a form including, but not limited to, the following: a bracelet, a watch, a gamepad, a smart phone, etc.

Further, before the game, the somatosensory device needs to establish a communication connection with the terminal (i.e. bind with the terminal), wherein a wired connection can be established between the somatosensory device and the terminal, and a wireless connection can also be established between the somatosensory device and the terminal. For example, when the somatosensory device establishes a wired connection with the terminal, the somatosensory device may be based on at least one of USB2.0 protocol, USB3.0 protocol, lightning 3 protocol, lightning 4 protocol; and when the somatosensory device establishes wireless connection with the terminal, the wireless connection can be based on at least one of Bluetooth protocol, wiFi protocol, infrared protocol, 2.4G communication protocol and NFC protocol.

S20, determining a motion path of the game object in the motion sensing game according to the acceleration data.

Specifically, the game object refers to a virtual object that is controlled and moved in a motion-sensing game. It may be various forms of objects, such as figures, vehicles, aircraft, etc., or abstract symbols or graphics. Game objects play an important role in games, one of the key factors in game play and experience.

The motion path is a path along which the game object moves along a certain trajectory in the motion-sensing game. In the invention, the motion path is determined according to the acceleration data acquired by the somatosensory equipment and preset algorithms and rules.

Specifically, the movement direction and speed of the game object may be determined according to the magnitude and direction of the acceleration data. For example, if the acceleration data in the horizontal direction is a positive value, the game object moves rightward; if the acceleration data in the vertical direction is a negative value, the game object moves downward. In addition, more complex motion paths can be realized by combining acceleration data in different directions.

In some embodiments, determining a motion path of a game object in the motion sensing game according to the acceleration data comprises the following steps:

S21, filtering and noise reduction processing is carried out on the acceleration data.

Specifically, since acceleration data acquired by the somatosensory device may have some noise or interference signals, filtering and noise reduction processing are required to be performed on the data so as to improve accuracy and stability of the data. The data may be processed by digital filters, smoothing filters, etc. For example, a low-pass filter may be used to remove high-frequency noise, a median filter may be used to remove bursty interference, or the like, or a kalman filter may be used to filter the acceleration data.

S22, generating an acceleration vector according to the processed acceleration data.

Specifically, the acceleration vector is a three-dimensional vector calculated from the acceleration data, which includes acceleration components in the horizontal direction and the vertical direction and components of gravitational acceleration. The moving direction and the moving speed of the motion sensing device can be determined according to the magnitude and the direction of the acceleration vector, and then the moving path of the game object is determined.

For example, the acceleration vector may be generated by:

1. calculating the X-axis component of the acceleration vector: the acceleration data is projected in the X-axis direction into a three-dimensional coordinate system, i.e. x=ax/g, where Ax represents the component of the acceleration data in the X-axis direction, g being the gravitational acceleration.

2. Calculating the Y-axis component of the acceleration vector: the acceleration data is projected in the Y-axis direction into a three-dimensional coordinate system, i.e., y=ay/g, where Ay represents the component of the acceleration data in the Y-axis direction.

3. Calculating a Z-axis component of the acceleration vector: the acceleration data is projected in the Z-axis direction into a three-dimensional coordinate system, i.e. z=az/g-1, where Az represents the component of the acceleration data in the Z-axis direction, and subtracting 1 is to remove the effect of gravitational acceleration.

4. The resulting three components constitute an acceleration vector, i.e., a= (X, Y, Z).

S23, determining the moving direction of the somatosensory equipment based on the acceleration vector.

Specifically, depending on the magnitude and direction of the acceleration vector, the moving direction of the motion sensing device, for example, left, right, forward, backward, etc., may be determined. In the implementation process, the acceleration vector can be normalized and converted into a unit vector so as to better determine the moving direction and speed of the somatosensory device.

For example, the normalization processing of the acceleration vector may be achieved by:

1. calculating the magnitude of the acceleration vector: i.e., the modulus of a, i.e., |a|=sqrt (X2+y 2+z 2).

2. Calculating normalized acceleration vectors: i.e., each component divided by the modular length of the vector, gives a' = (X/|a|, Y/|a|, Z/|a|).

It is worth to say that the normalized acceleration vector can better reflect the moving direction and speed of the motion sensing device, so that the motion path of the game object can be conveniently determined.

S24, selecting a matched motion path from a preset motion path track library according to the moving direction as the motion path of the game object.

Specifically, in a preset motion path trajectory library, motion paths of various types and directions, such as straight lines, arcs, curves, and the like, may be stored. According to the moving direction and speed of the motion sensing device, a matched motion path can be selected as a motion path of the game object. For example, when the motion sensing device moves leftwards, a motion path matching this direction such as a left straight line, a left turn, or the like may be selected. For different somatosensory games, a motion path track library needs to be preset according to actual conditions and design requirements so as to realize more accurate and smooth game experience.

It can be understood that directly selecting the matched motion path from the motion path trajectory library as the motion path of the game object with respect to the motion trajectory of the computing motion sensing device to obtain the motion path has the following advantages:

1. more accurate: when the matched motion paths are selected, matching can be performed according to the pre-stored real motion data, so that the matching is more accurate.

2. More stable: by selecting the matched motion path, the influence of abnormal values or noise in the acceleration data on the motion path can be avoided, so that the stability of the motion path is improved.

3. More efficient: calculating the motion trail of the motion sensing device consumes a great deal of computing resources, and directly selecting the motion trail from the motion trail library can save the computing resources and improve the running efficiency of the game.

4. The method is simpler: the motion trail of the motion sensing device needs to be calculated by complex algorithm and code, and the realization can be simpler and clearer by directly selecting the motion trail from the motion trail library

Of course, the design of the present application is not limited to this, and in other embodiments, the motion path of the game object may be obtained by calculating the motion track of the motion sensing device.

S30, generating a displacement instruction of the game object according to the acceleration data and a preset inching function.

Specifically, the slow Function (tracking Function) is a mathematical Function for describing the motion process of the object, and can adjust the motion speed of the object in time, so as to achieve the effects of acceleration, deceleration and the like of the motion, so that the motion of the object is more natural, comfortable and real.

Common creep functions include: linear slow motion function, sinusoidal slow motion function, exponential slow motion function, elastic slow motion function, rebound slow motion function, etc., each slow motion function has different characteristics and effects.

The displacement instruction refers to an instruction for controlling a change in the position of the game object. In a game, when a developer needs to control a game object to move along a specific path, the game object can be realized by generating a displacement instruction.

In general, the displacement instruction includes positional information of the game object to be moved in the current frame (game frame picture).

According to the technical scheme, the terminal can calculate the distance that the game object needs to move in the current frame according to the current position, the target position and the preset inching function of the game object, and convert the distance into a displacement instruction form.

It can be understood that the slow-moving function is set to generate the displacement instruction of the game object, so that the speed change of the game object in the motion process can be controlled, and the game object can move more truly, naturally and smoothly, and is more in line with the actual motion change.

In some embodiments, generating the displacement instruction of the game object according to the acceleration data and a preset inching function includes the following steps:

S31, screening out a time interval for completing an effective waving action from the acceleration data.

Specifically, a certain threshold and a certain condition can be set, and the time interval of the hand waving action meeting the requirements can be determined by combining actual testing and adjustment.

For example, the time interval for obtaining an effective waving motion can be achieved by the following method:

1. setting triggering conditions of the waving action, for example: the acceleration of the somatosensory device exceeds the set threshold.

2. After receiving the acceleration data, a point in time is found at which the acceleration change exceeds a threshold by processing the data.

3. And searching forwards or backwards for a period of time according to the set duration time of the hand waving action, and taking the period of time as a time interval of the hand waving action meeting the requirement.

Of course, the design of the present application is not limited thereto, and in other embodiments, the time interval may be determined by defining the minimum amplitude and the maximum amplitude, and the minimum speed and the maximum speed of the waving motion, and screening the acceleration data meeting the requirements, according to the game requirements. Or according to the game scene and design, the starting and ending positions of the waving action are defined, so that acceleration data meeting the requirements are screened to determine a time interval. The time interval can also be determined by defining the shortest time length and the longest time length of the hand waving action to screen the acceleration data meeting the requirements.

S32, calling a preset slow function, and taking the time interval as the input of the slow function.

Specifically, the time interval is used as an input of the slow motion function, and specific operations need to be performed according to the definition and implementation mode of the selected slow motion function. Typically, the input to the slow-moving function is a time parameter t, which indicates how much time the animation has been running, typically ranging from 0 to 1. And the time interval may be represented as a start time t1 and an end time t2.

If the input to the slow-moving function is time t, the time interval needs to be converted and mapped into a range of 0 to 1. A simple implementation is to map the start time t1 to 0 and the end time t2 to 1 of a time interval and then map the input parameter t of the slow function proportionally to said time interval, resulting in the actual time value t'. The specific calculation mode is as follows:

t'＝(t-t1)/(t2-t1)。

it should be noted that, the design of the present application is not limited to this, and parameters such as displacement, speed, etc. may be selected for the input of the slow motion function, and in this case, the parameters such as corresponding displacement, speed, etc. need to be converted into the input of the slow motion function according to the specific slow motion function definition and implementation.

S33, generating the displacement instruction according to the output of the slow motion function.

Specifically, according to a preset slow motion function and a time interval of the hand waving action, a real value can be obtained, which indicates a distance that the game object needs to move along the motion path. The distance instruction is decomposed into continuous small steps, and the displacement distance of each small step is calculated by a preset inching function. The displacement instructions of each small step can be stored in a queue, and then the displacement instructions are sequentially taken out of the queue according to a certain time interval, so that nonlinear movement of the game object is realized. It should be noted that the size and time interval of the displacement command need to be adjusted according to specific game requirements, so as to achieve the optimal game experience effect.

In some embodiments, the time interval is input as the slow function, comprising the steps of:

s321, mapping the starting time of the time interval to the starting value of the input range of the slow function;

s322, mapping the ending time of the time interval to the ending value of the slow function input range.

In particular, if the input range of the slow function is [0,1] and the start time of the time interval is 2 seconds, then mapping the start time of the time interval to the range of [0,1] may require the use of a linear mapping algorithm, i.e. mapping 2 seconds to 0, i.e. (2-start time)/(end time-start time) × (end value-start value) +start value. The end time may be mapped to the end value of the slow function input range based on substantially the same way as the start time.

S323, calculating the input value of the slow motion function corresponding to each moment in the time interval according to an interpolation algorithm.

For example, if the time interval is [2,4] seconds, the creep function input range is [0,1], and a quadratic creep function is used, then a quadratic interpolation algorithm may be used to calculate a creep function input value corresponding to each time instant within the time interval. These values may be used as part of a displacement instruction to control the non-linear movement of the game object along the motion path. In this way, the game object can be moved more smoothly and naturally.

In some embodiments, generating the displacement instruction from the output of the creep function includes:

s331, calculating a current coordinate value of the game object on the moving path at the current time according to an output value of a slow function, wherein the expression of the slow function is as follows:

f(t)＝(1-t) ² ×P ₀ +2×(1-t)×t×P ₁ +t ² ×P ₂ ；

wherein f (t) is an output coordinate value, P0, P1 and P2 are constants, t is an input value of the slow function, and the value range is [0,1]. It should be noted that P0, P1 and P2 may be adaptively adjusted according to practical situations.

S332, comparing the current coordinate value with the coordinate value of the previous moment, calculating the displacement of the game object on the moving path at the current moment, and generating the displacement instruction by the displacement.

For example, if the coordinate of the previous time is (2, 3) and the coordinate calculated at the current time is (3, 5), the displacement of the game object on the moving path at the current time is (1, 2), which is taken as the displacement command.

It should be noted that the above-listed slow-moving function is a bezier curve function, and selecting the bezier curve function as the desired slow-moving function has the following advantages:

1. flexibility: the Bezier curve function has flexibility, and the shape of the curve can be adjusted by adjusting the control point, so that different slow-moving effects can be achieved.

2. Smoothness: the Bezier curve function can generate a smooth curve, so that the motion track of the game object in the moving process is more natural.

3. Predictability: the Bezier curve function has predictability, and the position of the game object on the moving path can be predicted according to the input value of the inching function, so that the motion of the game object can be controlled better.

4. Easy realization: the Bezier curve function is simple to calculate and can be realized through basic mathematical operation, so that the complexity of realization and the cost of calculation are reduced.

In some embodiments, generating the displacement instruction from the displacement amount includes:

S3321, two time anchor points are set in the input interval of the slow-motion function so as to divide the input interval into three motion time periods of an acceleration section, a uniform speed section and a deceleration section.

Specifically, the whole displacement process can be divided into three motion time periods of an acceleration period, a uniform speed period and a deceleration period, and the motion time periods are divided by a preset time anchor point and an input interval.

S3322, setting different weight values for the slow motion function output of each motion time period according to the motion time period, wherein the weight values corresponding to the three motion time periods of the acceleration time period, the uniform speed time period and the deceleration time period are respectively a, b and c, and 0< a <1; c > b >1.

Specifically, in order to achieve a smooth transition and realistic sensation of movement of the game object, different weight values may be set for the creep function output for each movement period. In general, the acceleration section and the deceleration section need to move more smoothly than the constant velocity section, and thus the acceleration section and the deceleration section may be respectively set with a higher weight value than the constant velocity section. Meanwhile, since the deceleration section needs to transition from a section of high-speed motion to a stationary state, a higher weight value than the acceleration section is required to achieve a smoother transition.

For example, the acceleration section, the constant velocity section, and the deceleration section may be respectively corresponding to different sections within the input range [0,1] of the slow-motion function, and a corresponding weight value may be set for each section. For example, an acceleration segment may be associated with the input range [0,0.2], a constant velocity segment may be associated with the input range [0.2,0.8], and a deceleration segment may be associated with the input range [0.8,1], with corresponding weight values a, b, c being set, respectively. Where a is a value between 0 and 1, c is a value between 1 and 2, and a is less than 1 and c is greater than b. Thus, according to different input values, the output of the inching function can be weighted according to different weight values, so that smooth transition and realistic sensation are realized.

S3323, generating the displacement instruction according to the displacement and the weight value of the corresponding time period.

Specifically, the displacement amount may be multiplied by a corresponding weight value to obtain a final displacement value, and then a displacement instruction is generated according to the final displacement value.

It can be appreciated that by setting different displacement weight values for each movement time period, a more natural and realistic effect can be achieved in the movement of the game object. By setting different weight values, the motion trail of the game object in the acceleration, uniform speed and deceleration stages can be more in accordance with the motion rule of a real object, for example, when acceleration starts, the object gradually increases acceleration, but the acceleration is not always unchanged but gradually decreases, so that the situation that the game object suddenly changes speed in motion can be avoided, and the game playability and the ornamental value are increased.

And S40, controlling the game object to move in a nonlinear manner along the motion path according to the displacement instruction.

In particular, non-linear movement refers to a movement in which the change in velocity is not linear, i.e. non-uniform, during the movement of the object. In non-uniform motion, the displacement of the object is different in the same time, and the magnitude and direction of the velocity may also change over time.

By adjusting the position of the game object through the output of the inching function, the game object can be controlled to move along the motion path in an inactive mode.

It can be appreciated that the motion sensing game method according to the technical scheme of the present application has the following advantages compared with the conventional linear motion game scheme:

In summary, compared with the traditional linearly moving game scheme, the technical scheme of the method and the device can provide more real, smooth and flexible user experience, and has better playability and game performance.

In some embodiments, after controlling the game object to perform nonlinear movement along the motion path according to the displacement instruction, the somatosensory game method of the present application further includes:

and generating a game result according to the motion path of the game object.

Specifically, the game result refers to a score or prize obtained by the player after the player completes the game in the somatosensory game. Game outcome is typically assessed based on game rules and player performance, which may be game time, points, ratings, rewards, unlocking new game levels, and the like.

For example, game results may be generated by:

1. and acquiring a motion path of the game object, namely acquiring a motion track of the game object in the game process.

2. The motion path of the game object is analyzed, and a score is calculated according to the game rule.

3. And generating a game result according to the scoring condition and displaying the game result to the user.

Specifically, in the motion-sensing game, there are various ways of generating a game result according to a motion path of a game object, for example:

if the game is a fruit cutting game, indexes such as fruit cutting, continuous impact number and the like can be calculated according to the motion path of the game object, and the result of the ancient city game is scored according to the indexes;

if the game is a running game, calculating indexes such as jump height, air time, obstacle avoidance and the like according to the motion path of the game object, scoring according to the indexes and generating a game result;

if the game is a hit game, indexes such as the accuracy, the number of continuous hits and the like of a hit target can be calculated according to the motion path of a game object, and a game result is generated according to the index score;

if the game is a flight game, the game result may be generated by calculating the index such as the flight altitude, the speed, or the passing obstacle from the movement path of the game object, and scoring the game result from the index.

By generating the game result according to the motion path of the game object, the game is more challenging and interesting, and the user can intuitively know the game performance.
