Description

[0001] This application claims priority to Chinese patent application No. 202211668061.6, filed with the Chinese Patent Office on December 23, 2022, and titled “Three-dimensional action mouse,” and to Chinese patent application No. 202223455533.8, filed with the Chinese Patent Office on December 23, 2022, and titled “Three-dimensional action mouse,” the entire contents of which are hereby incorporated by reference into the present application. TECHNICAL FIELD

[0002] The present invention relates to the technical field of computer peripherals and further to a three-dimensional action mouse. STATE OF THE ART

[0003] In the application scenarios of existing mice, the table surface serves as a reflection reference surface for an optical position sensor. This means that the mouse's optical position sensor is moved downwards on the horizontal table surface, resting against it, and the movement information is captured by analyzing changes in the image position on the table surface. This design severely limits the mouse's movement range and results in a uniform operating posture for the user. The mouse can only move two-dimensionally on the table surface, and the two-dimensional movement of the mouse is converted into a two-dimensional movement of the cursor on the screen. Moving the mouse left and right controls the left and right movement of the cursor, and moving the mouse forward and backward controls the up and down movement of the cursor.

[0004] Conventional mouse control relies on the entire arm, meaning the upper arm moves the lower arm, and the lower arm moves the palm on the table surface. This requires movement of the entire arm with a relatively large range of motion. Furthermore, conventional mouse control is inconsistent with the movement of the human arm, especially when the entire arm's forward and backward movement causes the cursor to move up and down, which does not provide a more immersive user experience.

[0005] For the person skilled in the relevant technical field, it is currently a technical problem to be solved to harmonize the control of the mouse in physical space with the cursor on the screen. PRESENTATION OF THE INVENTION

[0021] The essence of the present invention is to provide a three-dimensional action mouse, wherein the control actions of the mouse in physical space correspond to the movement actions of the cursor on the screen.

[0022] In order to provide a person skilled in the relevant technical field with a better understanding of the technical solutions of the present invention, the three-dimensional action mouse of the present invention is presented and illustrated in more detail below in conjunction with the attached drawings and concrete embodiments.

[0023] In connection with the Fig. 1 to 11, the present invention provides a three-dimensional action mouse comprising structures such as a base 1, a rotary component 2, one or two groups of motion sensors 3, a mouse circuit board assembly, and a click button 4. The mouse circuit board assembly is located inside the mouse and is not shown in the accompanying drawings. The click button 4 serves to provide the mouse with a left or right mouse button for clicking.

[0024] The base 1 is a support structure, and the other components are mounted thereon. The rotary component 2 is mounted on the base 1 and can rotate relative to the base 1. The rotary component 2 can be grasped by the hand, and the wrist pivots to drive the rotary component 2 to rotate in at least two dimensions relative to the base 1, or the wrist pivots to drive the base 1 and the rotary component 2 to rotate in at least two dimensions. It should be clarified that rotation in two dimensions means that the rotary component 2 can rotate in space about at least two different axes of rotation, whereby the two axes of rotation are not parallel to each other. The movement of the entire mouse is understood to involve two cases: In the first case, the rotary component 2 rotates in two dimensions relative to the base 1, i.e., only the rotation component 2 rotates; in the second case, the rotation component 2 rotates in one dimension relative to the base 1, while the base 1 itself rotates in one dimension, that is, the rotation component 2 and the base 1 cooperate to achieve a rotation in two dimensions.

[0025] In the aforementioned first case, the rotation of the rotary component 2 in two dimensions can trigger the motion sensors, or in the aforementioned second case, the rotation of the base 1 and the rotary component 2 in two dimensions can trigger the motion sensors. In the aforementioned first and second cases, rotation information about the rotation in two dimensions can be detected by the motion sensors.

[0026] The motion sensors are arranged in two ways: A) one group of motion sensors is provided, and B) two groups of motion sensors are provided. If one group of motion sensors is provided, one group of motion sensors detects rotation information in two dimensions; if two groups of motion sensors are provided, the two groups of motion sensors each detect rotation information in one of the two dimensions.

[0027] The mouse circuit board receives the rotation information detected by the motion sensors, processes the two-dimensional rotation information detected by the motion sensors, and then transmits the two-dimensional rotation information to a computer according to the mouse communication protocol. This rotation information corresponds to a planar two-dimensional movement of a cursor on the computer screen. That is, the three-dimensional action mouse provided by the present invention is controlled by the user's hand to move three-dimensionally in space. Rotation about at least two different axes of rotation can be achieved, with rotation about each axis of rotation corresponding to a translational displacement in one dimension of the two-dimensional space on the screen.Compared to conventional mice that can only move flatly on the table, the three-dimensional action mouse of the present invention enables three-dimensional control by the hand, so that the actual movement of the hand in physical space can match the movement of the cursor on the screen and provide a more realistic and immersive user experience.

[0028] Various types of motion sensors can be used in the present invention, with the various sensors being arranged differently depending on their mode of operation. In the embodiments of this description, some essential types are listed, including reflective optoelectronic sensors such as optical mouse sensors, transmitting and receiving optoelectronic sensors such as encoders, or directly sensing motion sensors such as gyroscopes, which do not require a reference surface. Any combination of one or two of the three aforementioned sensor types can be used as the motion sensor. It should be noted that when using an optical mouse sensor or an encoder, a cooperating reference surface 5 must be provided, whereas when using a gyroscope, no corresponding reference surface 5 needs to be provided.The optical mouse sensor enables detection through the relative displacement to the reference surface 5, while the encoder enables angle and displacement detection through the relative movement or rotation of its internal read head to the reference surface 5 (in the case of the encoder, to the encoder disk or encoder scale).

[0029] The rotary component 2 of the present invention can be designed in several forms, mainly in two forms: firstly, the rotary component 2 is a one-piece construction (with only a single movable component), and secondly, the rotary component 2 comprises two movable components, wherein the rotary component 2 comprises a first rotary part 2.1 and a second rotary part 2.2, wherein the first rotary part 2.1 is rotatable about a first rotation axis (I in Fig. 1) is rotatably connected to the base 1 and the second rotating part 2.2 about a second axis of rotation (II in Fig. 1) is rotatably connected to the first rotating part 2.1.

[0030] Based on the aforementioned solutions, the present invention provides a solution for the arrangement of motion sensors. For the aforementioned first case, i.e. when the rotary component 2 rotates in two dimensions relative to the base 1, there are several solutions for the arrangement of the sensors. The most important ones are listed below: Solution 1: A single group of motion sensors is provided, such as a multi-axis gyroscope or an optical mouse sensor or an encoder, which is arranged on the one-piece rotary component 2 or the second rotary part 2.2. A reference surface 5 is required which interacts with the motion sensors and is arranged on the base 1. When the one-piece rotary component 2 or the second rotary part 2.2 rotates in two dimensions, the motion sensors can detect the rotation information in these two dimensions. Solution 2: Two groups of motion sensors are provided, such asTwo groups of gyroscopes or optical mouse sensors or encoders, all arranged on the one-piece rotary component 2 or the second rotary part 2.2, requiring a reference surface 5 (for encoders, the encoder scale) that interacts with the motion sensor and is arranged on the base 1, each group of motion sensors capturing rotation information separately in one dimension. Solution 3: One group of motion sensors is arranged on the first rotary part 2.1 and the other group of motion sensors is arranged on the second rotary part 2.2, requiring two reference surfaces 5 that interact with the motion sensors and are arranged respectively on the base 1 and the first rotary part 2.1, wherein upon respective rotation of the first rotary part 2.1 and the second rotary part 2.2, the motion sensors located thereon each capture their respective rotation information.

[0031] For the aforementioned second case, i.e. when the rotating component 2 and the base 1 interact with each other to rotate in two dimensions, there are also several solutions for arranging the sensors. The most important ones are listed below: Solution (I): A single group of motion sensors is provided, such as a group of multi-axis gyroscopes, which is arranged on the rotating component 2, whereby this single group of motion sensors can detect the respective rotation information of the rotating component 2 and the base 1. Solution (II): Two groups of motion sensors are provided, such as two groups of gyroscopes, which are all arranged on the rotating component 2, whereby the two groups of motion sensors each detect the respective rotation information of the rotating component 2 and the base 1.Solution (III): One group of motion sensors is arranged on the rotary component 2 and the other group of motion sensors is arranged on the base 1, whereby two reference surfaces 5 are required which cooperate with the motion sensors and are arranged respectively on the base 1 and the support surface, wherein upon the respective rotation of the rotary component 2 and the base 1, the two groups of motion sensors each detect the respective rotation information of the rotary component 2 and the base 1.

[0032] In addition to the aforementioned arrangements, the motion sensors and the cooperating reference surfaces 5 can be swapped in their positions, and the optical mouse sensors can be replaced by other reflective optoelectronic sensors, and the encoders can be replaced by other transmitting and receiving optoelectronic sensors. These specific embodiments are intended to fall within the scope of the present invention.

[0033] The two-dimensional rotation information acquired in all the above configurations is processed accordingly by the mouse circuit board assembly and then sent to the computer according to the mouse communication protocol, where the two-dimensional rotation information corresponds to the planar two-dimensional movement of the cursor on the computer screen.

[0034] It should be noted that: 1) A single optical mouse sensor typically generates digital movement information in the X and Y directions relative to the reference surface 5 simultaneously, wherein in the configuration of two groups of movement sensors with optical mouse sensors, the mouse circuit board assembly extracts from the movement information data generated by a single optical mouse sensor, preferably data representing the rotation in one dimension in which this sensor is located, and sends it to the computer as information in one of the two dimensions according to the mouse communication protocol, wherein the extracted data can be either separate movement information in the X or Y direction or a combination of movement information in the X and Y directions, depending on the relationship between the actual position of the sensor and the direction of rotation in the dimension in which it is located.When configuring two groups of motion sensors with gyroscopes, the mouse PCB assembly for a single multi-axis gyroscope processes its motion information data in a similar way. 2) Using two gyroscopes instead of one multi-axis gyroscope to acquire rotation information in two dimensions is advantageous for adjusting the optimized landing position and angle of each gyroscope according to the rotation direction in two dimensions. This is not just a direct replacement relationship where one two-axis gyroscope corresponds to two single-axis gyroscopes.

[0035] Specifically, the reference surface 5 of the present invention is a curved surface or a flat surface, as described in connection with the Fig. 1 and Fig. 2, in which the reference surface 5 arranged on the base 1 is shown, wherein the reference surface 5 is designed as a curved surface. It should be noted that the reference surface 5 arranged on the base 1 shown in the figures can be a spherical surface or an irregular curved surface, as long as it can enable detection in cooperation with the motion sensor. As described in connection with Fig. As shown in Figure 7, when a motion sensor is provided on the base 1, the reference surface 5 is an underlying support surface, wherein the reference surface 5 is a flat surface.

[0036] As in connection with the Fig. 1 to 5 and 9 and 10, the first rotating part 2.1 is a disc-shaped construction, wherein the first rotation axis is approximately vertical and the first rotating part 2.1 can rotate about the approximately vertical, first rotation axis; and the second rotation axis is approximately horizontal and the second rotating part 2.2 rotates about the horizontal, second rotation axis. Fig. 1 and Fig. 2 differ mainly in the position of the second rotation axis. In Fig. 1 the first and second rotation axes intersect and in Fig. 2, the first and second rotation axes do not intersect. Fig. 3 and Fig. 4 differ mainly in the inclination of the first axis of rotation to the horizontal plane.

[0037] In connection with the Fig. 1 and Fig. 2, a spherical reference surface 5 is arranged on the base 1, whereby only a motion sensor needs to be arranged on the second rotating part 2.2, which, in cooperation with the reference surface 5, executes a rotation in two dimensions. In the case of the Fig. 3 and Fig. In the construction shown in Figure 4, a group of motion sensors is arranged on the lower surface of the first rotating part 2.1, and a plane on the base 1 serves as a reference surface 5 for this group of motion sensors, wherein the reference surface 5 represents the upper surface of the base 1. A further group of motion sensors is arranged on the second rotating part 2.2, and a further reference surface 5 corresponding to this group is arranged on the first rotating part 2.1. When the first rotating part 2.1 moves relative to the base 1, the motion sensors on the first rotating part 2.1 enable detection in cooperation with the reference surface 5 arranged on the base 1; when the second rotating part 2.2 moves relative to the first rotating part 2.1, the motion sensors on the second rotating part 2.2 enable detection in cooperation with the reference surface 5 arranged on the first rotating part 2.1. In conjunction with the Fig. 3 and Fig. 4, the detection surface of the motion sensor on the second rotating part 2.2 can be arranged at the front or side. If the detection surface of the motion sensor on the second rotating part 2.2 is facing forward, the reference surface 5 is a curved surface; if the detection surface of the motion sensor on the second rotating part 2.2 is facing sideways, the reference surface 5 is a flat surface.

[0038] In connection with the Fig. 7 and Fig. In the construction shown in Figure 8, a group of motion sensors 3 is arranged on the lower surface of the base 1. The base 1 is placed on a support surface, which serves as a reference surface for the motion sensors on the base 1. Another group of motion sensors 3 is arranged on the rotating component 2, and a further reference surface 5 corresponding to this group is arranged on the base 1. When the base 1 moves relative to the support surface (e.g., a table surface), the motion sensors 3 on the base 1 enable detection in cooperation with the support surface; when the rotating component 2 moves relative to the base 1, the motion sensors on the rotating component 2 enable detection in cooperation with the reference surface 5 arranged on the base 1.

[0039] In connection with the Fig. 7 and Fig. 8, during a rotation in two dimensions, through the interaction of the rotating component 2 and the base 1, several groups of rollers 1.1 can be arranged on the bottom surface of the base 1 to support the base 1 from below and enable a rolling movement when the base 1 rotates relative to the support surface. This helps to convert the frictional sliding between the base 1 and the support surface into a rolling movement between the rollers 1.1 and the support surface, resulting in a faster rotation of the base 1. When arranging the rollers 1.1, it is optimal if their axial direction is aligned with the wrist as the center, which corresponds to the rollers 1.1 rolling on the circumference with the wrist as the circle center.

[0040] In connection with Fig. In the construction shown in Figure 9, two groups of motion sensors 3 are arranged on the second rotating part 2.2, and two reference surfaces 5, each corresponding to the two groups of motion sensors 3, are arranged on the base 1. When the handle section rotates the second rotating part 2.2 together with the first rotating part 2.1 on the base 1 in two dimensions, the two motion sensors 3 on the second rotating part 2.2 enable detection in cooperation with the respective reference surface 5 and each acquire the rotation information in one of the two dimensions. If the two groups of motion sensors 3 are encoders, the reference surfaces 5, which enable detection in cooperation with the two groups of motion sensors 3, are encoder scales. In conjunction with Fig. Figure 9 roughly illustrates the operation of the two encoders. The stripes on the reference surface 5 correspond to the grid holes on the encoder scale. The grid holes have the elongated strip shape shown in the figure, with the grid holes on one reference surface 5 arranged horizontally and the grid holes on the other reference surface 5 arranged vertically. The light source for transmitting and the read head for receiving on the encoder are each located on one side of the reference surface 5 (not shown in the figure) and are mounted in a fixed relationship to one another on the second rotating part 2.2. When the encoder moves with the second rotating part 2.2, the light source and the read head, which are each located on one side of the reference surface 5, move together relative to the reference surface 5.When the light source and read head move across the horizontal or vertical grid holes, the encoder immediately generates pulse signals. The pulse signals generated across the horizontal grid holes represent the acquisition of rotational information in one dimension, and the pulse signals generated across the vertical grid holes represent the acquisition of rotational information in another dimension. The number of pulse signals corresponds to the number of grid holes over which the light source and read head move, enabling the acquisition of rotational information in two dimensions. Specifically, in . Fig. 9, the two reference surfaces 5 can be combined into one reference surface 5, i.e., two parts are formed on one reference surface 5, with the left grid holes arranged horizontally and the right grid holes arranged vertically. This can simplify assembly and reduce costs, and improve the consistency of series products.

[0041] The Fig. 10 and Fig. 11 shows roughly how the detection of rotation in two dimensions with an encoder works. Fig. 10 is a schematic representation of the overall structure and Fig. 11 is a structural schematic diagram of the second rotating part 2.2. In conjunction with the Fig. 10 and Fig. 11, a group of motion sensors 3, i.e., an encoder, is arranged on the second rotating part 2.2, and a reference surface 5, i.e., an encoder scale, is arranged on the base 1. The light source (not shown in the figures) for transmitting and the read head 3.1 for receiving on the encoder are each located on one side of the reference surface 5 and are mounted in a fixed relationship to each other on the second rotating part 2.2. In this embodiment, the read head 3.1 is located on the side of the handle section. In conjunction with Fig. 10, the circular holes on the reference surface 5 correspond to the grid holes on the encoder scale. These grid holes are regularly arranged, ie, aligned with each other in any horizontal and vertical row. In conjunction with Fig. 11, two groups of read heads 3.1 are arranged on the encoder, one group being arranged horizontally and the other vertically. When the encoder moves with the second rotating part 2.2, the light source and the read head 3.1, each located on one side of the reference surface 5, move together relative to the reference surface 5. When the horizontal read head 3.1 on the encoder moves over a row of horizontal grid holes on the reference surface 5, the encoder generates a group of pulse signals corresponding to a rotation in one dimension. When the vertical read head 3.1 on the encoder moves over a row of vertical grid holes on the reference surface 5, the encoder generates another group of pulse signals corresponding to a rotation in another dimension.The number of pulse signals corresponds to the number of rows of grid holes over which the read head moves, enabling the acquisition of rotational information in two dimensions.

[0042] It should also be noted that in the Fig. 9 and Fig. 10, a group of read heads can consist of multiple optoelectronic elements. By determining the order in which the multiple optoelectronic elements receive the emitted light source, the encoder can obtain directional information about forward and reverse rotation in the same dimension.

[0043] Preferably, the first rotation axis in the present invention is inclined to the left or right, wherein the first rotation axis forms an angle of between 45 and 90 degrees with the horizontal plane or the first rotation axis forms an angle of between 45 and 90 degrees with the second rotation axis in order to improve the operating experience for left- or right-handed users. As described in connection with Fig. As shown in Figure 4, the upper surface of the base 1 is formed as an inclined surface, and the first rotation axis is correspondingly inclined to one side. The structure inclined to the left in the figure can be adapted to right-hand operation. When adapted to left-hand operation, the first rotation axis can be tilted to the right. The first rotation axis forms an angle between 45 and 90 degrees with the horizontal plane, or the first rotation axis forms an angle between 45 and 90 degrees with the second rotation axis. The specific angle can be adjusted according to user needs, thus suiting different users, providing a more comfortable operating experience, and further improving ergonomics.

[0044] In connection with the Fig. 1 to 4, in the present invention, a support recess 2.2.1 for supporting the hand is arranged on the second rotating part 2.2. The main part of the second rotating part 2.2 consists of two side plates and a cross plate. The two side plates are attached to the two sides of the cross plate, and all three parts form a "concave" recess for receiving the hand, whereby the lower part of the hand can be supported by the cross plate.

[0045] A gripping section 2.2.2 for gripping by hand is arranged on the second rotating part 2.2, wherein the gripping section 2.2.2 is located in front of the first rotational axis and the second rotational axis. In conjunction with the Fig. 1 to 4, the grip section 2.2.2 is arranged on the cross plate of the support recess 2.2.1. If one side of the first rotation axis and the second rotation axis is close to the body, the grip section 2.2.2 is located in front of the first rotation axis and the second rotation axis to facilitate palm gripping, while the first rotation axis and the second rotation axis are located closer to the wrist, thus better adapting to wrist movements.

[0046] Preferably, the first axis of rotation and the second axis of rotation each pass through the wrist during use. In conjunction with the Fig. 1 to 4, the second rotating part 2.2 is provided with a support recess 2.2.1, at the bottom of which the hand can rest. The support recess 2.2.1 can deflect the hand and provides space for it. The support recess 2.2.1 arranged on the second rotating part 2.2 allows the first rotational axis and the second rotational axis to spatially intersect or converge. If the first rotational axis and the second rotational axis both pass through the wrist, the comfort of wrist movement in all directions can be improved.

[0047] In addition to the arrangement of the rotary component 2 as a combination of the first rotary part 2.1 and the second rotary part 2.2, the present invention also provides another specific arrangement, which is presented below:

[0048] The rotary component 2 is designed as an independent structure, whereby the individual rotary component 2 forms a ball pair in cooperation with the reference surface 5. In conjunction with Fig. 6, in which the reference surface 5 is preferably formed as a spherical groove structure, the rotary component 2 is provided with an outwardly curved spherical surface that is in contact with the reference surface 5 and is precisely adapted to it. The spherical surface of the rotary component 2 preferably coincides with the sphere center of the reference surface 5. The surface of the reference surface 5 is larger than the spherical surface of the rotary component 2, so that the rotary component 2 can be rotated relative to the reference surface 5 at any angle and in any direction.

[0049] In this construction, a motion sensor can be arranged on the rotating component 2, which, in cooperation with the reference surface 5, enables detection. The sensor can also be arranged on the spherical groove of the base 1, with the spherical surface of the movable component serving as the reference surface 5. These specific embodiments should all fall within the scope of the present invention. In connection with Fig. 6 In this design, the grip section 2.2.2 is arranged behind the ball pair, and the grip section 2.2.2 is gripped by hand for the corresponding control. The rotary component 2 or the reference surface 5 in the ball pair consists of an elastic mechanism or an elastic material and can thus reduce the friction force during the relative movement of the rotary component 2 and the reference surface 5, ensuring smooth movement.

[0050] In connection with the Fig. 1, Fig. 5, Fig. 6, Fig. 9 and Fig. 10, the position of the reference surface 5 relative to the position of the hand during use can be arranged in various positions, with the primary position being the front of the hand and secondary, but possible, positions including the back, top, bottom, left, or right side of the hand. When the reference surface 5 is arranged in these positions, its optimal orientation is toward the wrist as the center.

[0051] In connection with the Fig. 5 and Fig. 6 In the present invention, a support plate 6 is placed below and / or behind the rotary component 2 for supporting part or all of the hand, wrist, and forearm from below when gripping with the hand. The support plate 6 can be used to support the arm, and the upper surface of the support plate 6 can be formed with an appropriate shape as required, for example, as a flat surface or as a cylindrical surface. A flexible material can also be provided on the upper surface of the support plate 6 to reduce the pressure on the support point and provide a more comfortable user experience. If a gyroscope is used as the motion sensor, Fig. 6, the reference surface 5 can be completely omitted and only the support plate 6 can be retained, which supports the fixation of the arm position and only allows the wrist to pivot. This helps prevent interference with the gyroscope detection due to random movements of the arm.

[0052] The three-dimensional action mouse of the present invention further includes a trigger mechanism used to control the stopping of the cursor's action. The trigger mechanism is triggered by a first hand action into a sleep state so that the mouse circuit board assembly stops sending valid movement information to the computer; and the trigger mechanism is triggered by a second hand action into an operating state so that the mouse circuit board assembly continues sending valid movement information to the computer. When the trigger mechanism receives the signal from the first hand action, the on-screen cursor stops moving. When the trigger mechanism receives the signal from the second hand action, the on-screen cursor starts moving again. The on-screen cursor movement continues to be controlled by the motion sensor.The trigger mechanism is a switch that determines whether the cursor moves or not.

[0053] As in connection with the Fig.1 to 11, the trigger mechanism of the present invention is a mechanical switch or sensor, wherein the first hand action is pressing or releasing the trigger mechanism, and the second hand action is releasing or pressing the trigger mechanism. If the first hand action is pressing the trigger mechanism, the second hand action is releasing the trigger mechanism; and if the first hand action is releasing the trigger mechanism, the second hand action is pressing the trigger mechanism. During operation, when the cursor stops moving, the hand-driven spatial movement of the movable component no longer controls the movement of the cursor, and the movable component can resume control of the cursor from any position.In addition to mechanical switches or sensors, other electronic components that can transmit state changes or certain mechanical structures can be used as trigger mechanisms, each with the aim of ending or continuing the mouse's function of sending valid movement information to the computer.
