Detailed Description

The present invention will be described in further detail with reference to examples and drawings, but embodiments of the present invention are not limited thereto.

Example 1

The invention discloses a magic cube operation monitoring method which is mainly realized through computing equipment and comprises the following specific steps:

for a magic cube to be operated, receiving magic cube body position information detected by a body position detection sensor and rotation information of each surface of the magic cube detected by each surface rotation detection sensor; in the magic cube, the body position detection sensor is arranged in an inner ball of the magic cube and rotates along with the inner ball; the layers of the modules in the magic square, which are fixed in relative positions, are bound with the inner ball, namely the layers drive the inner ball to rotate when rotating; the layer where the modules with fixed relative positions in the magic cube are located is defined as a fixed layer, and other layers are defined as non-fixed layers; each surface of the non-fixed layer in the magic cube is provided with a corresponding surface rotation detection sensor, and the magic cube detects the rotation of each surface relative to the inner ball through the surface rotation detection sensors of each surface. For example, for a third-order magic cube, as shown by the dotted line in fig. 1a, the layers where the modules fixed at opposite positions in the magic cube are located are middle layers M, E and S, where the middle layer M is a fixed layer between two surfaces of a rotating surface R and a rotating surface L, the middle layer E is a fixed layer between two surfaces of a rotating surface U and a rotating surface D, the middle layer M is a fixed layer between two surfaces of a rotating surface R and a rotating surface L, and the middle layer S is a fixed layer between two surfaces of a rotating surface F and a rotating surface B; the magic cube middle layer M, E and the S layer can drive the magic cube inner ball to rotate when rotating, so that the body position detection sensor generates rotation information.

If the information transmitted by the surface rotation detection sensor of one surface or a plurality of adjacent surfaces is received currently, judging that the magic cube performs single-layer or multi-layer operation without a fixed layer currently, firstly acquiring a current coordinate system of the magic cube, and then identifying the single-layer or multi-layer operation of the solid magic cube under the current coordinate system of the magic cube and the target state after the single-layer or multi-layer operation according to the rotation information transmitted by the surface rotation detection sensor; for example, for a third-order magic cube, when the magic cube is operated at present, the R surface of the magic cube rotates 90 degrees clockwise, at this time, the surface rotation detection sensor of the R surface generates clockwise rotation 90 degrees information, the computing equipment can acquire that the magic cube is actually rotated 90 degrees clockwise according to the information, and the target state of the magic cube after the current operation can be identified according to the target state of the magic cube before the magic cube is operated and the current operation performed under the current coordinate system of the magic cube, thereby realizing the monitoring of the current operation of the magic cube. In the operations of the magic cube defined by the WCA, there are single-layer operation sets { R, R ', L, L ', F, F ', B, B ', U, U ', D, D ' }, corresponding to clockwise and anticlockwise 90 DEG rotations R and R ' on the right side of R, and the operations of left L, front F, rear B, upper U and lower D are respectively performed, but the operation is an absolute operation which uses a user as a visual angle and does not correspond to a fixed color, the operation in the embodiment identifies the operation set as an absolute operation which determines that a certain color corresponds to R, L, F, B, U, D surfaces according to the body position information of the current magic cube, namely the acquired current coordinate system of the magic cube, and then acquires the surface rotation information to identify a certain single-layer operation.

If the information transmitted by the surface rotation detection sensor and the body position detection sensor of one or more adjacent surfaces is currently received, judging that the solid magic cube is currently rotated by double-layer or multi-layer operation with a fixed layer, firstly acquiring a current coordinate system of the magic cube, and then identifying the operation of the magic cube under the current coordinate system of the magic cube and the target state after the operation according to the rotation information transmitted by the surface rotation detection sensor and the body position information transmitted by the body position detection sensor; and determining a magic cube coordinate system according to the next operation of the magic cube according to the visual angle of the user and the body position information transmitted by the current body position detection sensor. For example, for a third-order magic cube, currently the magic cube is operated so that the right two layers of the magic cube simultaneously rotate by 90 degrees in time, and at this time, the middle layer belonging to the fixed layer is included in the right two layers because the right two layers simultaneously rotate, so that the inner ball in the magic cube rotates along with the inner ball; under the condition, the left surface rotation detection sensor of the magic cube detects 90-degree transposition information, and the body position detection sensor also detects body position information, the computing equipment recognizes and determines that the magic cube is in a right two-layer state and simultaneously rotates clockwise by 90 degrees after receiving the 90-degree transposition information of the left surface rotation detection sensor and the 90-degree body position change information of the body position detection sensor, and the computing equipment can recognize the target state of the magic cube after the current operation according to the target state before the magic cube is operated and the current operation of the magic cube under the current coordinate system of the magic cube, so that the current operation of the magic cube is monitored. In the magic cube layer-first method and cfop algorithm, the two-layer operation sets { r, r ', l ', f ', b ', u ', d ' }, corresponding to clockwise 90 ° rotation r and r ' of the two layers on the right side of r, and the two-layer operations of left l, front f, rear b, upper u and lower d are respectively used for the same analogy, but the operation is the operation taking the user as the visual angle and is not the absolute operation corresponding to the fixed color, and the above operation in the embodiment enables the identification of the set operation to determine that a certain color corresponds to r, l, f, b, u, d face according to the body position information of the last magic cube. However, under the condition that body position data is not considered, the clockwise 90-degree rotation of the R right-hand double layer can be identified as L ', namely, the rotation is equivalent to the anticlockwise single-layer rotation of the left-hand surface, so that the identification method is that the rotation L' of the single layer is detected, the change of the R-direction body position data is added, then the rotation is identified as R, after the rotation is completed, the corresponding R, L, F, B, U, D surfaces of all color surfaces (the relative positions of the finger are fixed and the corresponding positions of the modules are fixed and the middle-most modules of all surfaces are fixed in a third-order magic cube, namely, the coordinate system of the magic cube is changed, and the coordinate system of the magic cube is used as a magic cube coordinate system according to the next operation of the magic cube, and other double-layer operations are the same;

If the information transmitted by the surface rotation detection sensor and the body position detection sensor on the opposite surface is received currently, judging that the solid magic cube only rotates on the fixed layer, firstly acquiring a current coordinate system of the magic cube, and then identifying middle-layer operation of the magic cube under the current coordinate system of the magic cube and a target state after the middle-layer operation according to the rotation information transmitted by the surface rotation detection sensor on the opposite surface and the body position information transmitted by the body position detection sensor; and determining a magic cube coordinate system according to the next operation of the magic cube according to the visual angle of the user and the body position information transmitted by the current body position detection sensor. For example, for a third-order magic cube, if the middle layer M layer of the magic cube is operated so that the M layer rotates 90 degrees, the rotation detection sensors on the left and right opposite sides of the middle layer M layer can detect the transposition information, and as the middle layer M layer rotates to drive the inner ball of the magic cube to rotate, the position detection sensor can also detect the position change information, and the computing equipment can identify and determine that the magic cube rotates corresponding to the middle layer when receiving signals sent by the surface rotation detection sensors on the opposite sides and the position detection sensor, and can identify the target state of the magic cube after the current operation according to the target state of the magic cube before the operation and the current operation of the magic cube under the current coordinate system of the magic cube, thereby realizing the monitoring of the current operation of the magic cube. In the magic cube layer first method and the cfop algorithm, the middle layer operation set { M, E, S }, M is a middle layer between two sides of a rotary RL, E is a middle layer between two sides of a UD, S is a middle layer between two sides of a FB, taking M operation as an example, M is equivalent to R '+L under the condition of no body position data, namely, the anticlockwise direction of the R surface and the clockwise direction of the L surface are simultaneously rotated, and the method is characterized in that two simultaneous single-layer rotations L and R' are detected and the change of body position data in the R direction is simultaneously acquired and then is identified as M, R, L, F, B, U, D surfaces corresponding to all color surfaces are remapped after the rotation is in place, namely, the coordinate system of the magic cube is changed, and the other middle layers are operated in the same way;

If only the information transmitted by the body position detection sensor is received currently, judging that the entity magic cube performs rolling operation, firstly acquiring a current coordinate system of the magic cube, and identifying the rolling operation of the magic cube under the current coordinate system of the magic cube and the target state after the rolling operation according to the body position information transmitted by the body position detection sensor; and determining a magic cube coordinate system according to the next operation of the magic cube according to the visual angle of the user and the body position information transmitted by the current body position detection sensor. In the magic cube restoration algorithm, a rotation operation set { x, x ', y, y ', z, z ' }, the magic cube rolls around the x, y and z axes of the three-dimensional coordinate axis in a clockwise direction and anticlockwise direction, the identification method is to collect body position change data, and R, L, F, B, U, D surfaces corresponding to all color surfaces are remapped after rotation is in place; i.e. the coordinate system of the cube is changed.

In the third-order magic cube, the relative positions of the modules in the middle of the six faces are fixed, for example, the faces of the magic cube where the green, blue, red, orange, yellow and white fixed modules are located are mapped to the R, L, F, B, U, D faces in the restored state, namely, the coordinate system of the magic cube is as follows: upper yellow, lower white, left blue, right green, front red, rear orange; when the two sides of the right side of the magic cube rotate clockwise, under the layer-first method and the cfop algorithm, the next restoration operation algorithm is performed with the user as the visual angle, so in the method of the embodiment, after the operation, the coordinate system of the magic cube is defined by the upper red, the lower orange, the left blue, the front green, the front white and the rear yellow, namely, the surfaces of the green, blue, white, yellow, red and orange fixing modules are respectively mapped onto the R, L, F, B, U, D surfaces, and when the next magic cube is operated, the operation is performed according to the corresponding algorithm by using the coordinate system of the magic cube.

In the embodiment, the time from the last target state to the current target state of the magic cube is recorded, and a step list of the absolute color and position change of the magic cube and the corresponding time are determined according to the time; and determining a step list of the change of the magic cube coordinate system and corresponding time according to the time. The magic cube goes from any one disturbing state A to a complete reduction state O, the middle part is subjected to a plurality of middle disturbing states A1 … … An, after each manipulation operation, the disturbing states are updated, the computing equipment records the time spent for correspondingly changing the disturbing states, a step list which is in absolute color and position, namely ignoring the position change (yellow U white D, F red B orange, L blue R green) and corresponding time are provided according to user selection, or a step list which is in absolute reduction path and time and corresponds to R, L, F, B, U, D faces corresponding to all color faces of the position change and corresponding time are provided as VR reduction paths and times, and the time period can be subdivided into the time of each stage and the observation time among each stage according to the characteristics of algorithms such as layer first method and cfop and the like, so that the user data analysis is used for helping the user to train.
