Description

[0002] At present, the existing method of adjusting peripheral parameters is usually to change the parameters of peripherals through touch technology. Touch technology provides an intuitive and convenient operation method. Users do not need to gradually adjust parameters through traditional buttons or knobs, but can quickly adjust them directly on the touch interface through gestures such as sliding, dragging, and zooming. This operation method not only improves the user experience, but also makes the adjustment of parameters more flexible and precise.

[0003] However, the traditional method of adjusting peripheral parameters through touch technology has the following disadvantages: 1) Limited accuracy and sensitivity: Touch technology usually relies on the contact area and force between the finger and the touch surface to identify the operation, but this is insufficient for sensing subtle changes in force. This limitation is particularly evident in scenarios that require high-precision adjustments. 2) Lack of stereoscopic sense and naturalness: Touch technology is still a flat two-dimensional operation, and the two-dimensional touch interface cannot provide three-dimensional stereoscopic sense and physical feedback similar to the real world. 3) Limited applicability: Touch technology is mainly suitable for flat devices and is difficult to directly apply to three-dimensional peripherals with complex shapes and structures.

[0047] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0048] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0049] At present, the existing method of adjusting peripheral parameters is usually to change the parameters of the peripherals through touch technology. However, the traditional method of adjusting peripheral parameters through touch technology has the following disadvantages: 1) Limited accuracy and sensitivity: Touch technology usually relies on the contact area and force between the finger and the touch surface to identify the operation, but this is insufficient for the perception of subtle changes in force. This limitation is particularly evident in scenarios that require high-precision adjustments. 2) Lack of stereoscopic sense and naturalness: Touch technology is still a flat two-dimensional operation, and the two-dimensional touch interface cannot provide three-dimensional stereoscopic sense and physical feedback similar to the real world. 3) Limited applicability: Touch technology is mainly suitable for flat devices and is difficult to directly apply to three-dimensional peripherals with complex shapes and structures.

[0050] In view of this, the present invention provides a peripheral parameter adjustment method based on pressure sensing control, which accurately senses the slight pressure changes applied by the user to the peripheral through a pressure sensor array, maps the pressure digital signal to the parameter adjustment of the peripheral according to a preset pressure-parameter mapping relationship, and realizes precise control of the peripheral parameters. The following will be explained and introduced through multiple embodiments.

[0051] Figure 1 The flowchart of the peripheral parameter adjustment method based on pressure sensing control provided by the present invention. Figure 1 As shown, the peripheral parameter adjustment method based on pressure sensing control includes steps S1 to S3, wherein:

[0052] Step S1, sensing the pressure change applied by the user to the pressure sensing area of ​​the target peripheral device, and obtaining pressure data;

[0053] Specifically, the pressure sensor array installed in the pressure sensing area of ​​the target peripheral device senses the pressure changes applied by the user to the peripheral device and outputs a pressure simulation signal. The pressure sensing area here can be set at any position on the surface of the peripheral device where the user may apply pressure, such as the gripping part. The peripheral device may include a mouse, a game controller, a medical rehabilitation device, and a robot remote control device. When the target peripheral device is a mouse, the peripheral parameter to be adjusted may be the mouse sensitivity; when the target peripheral device is a game controller, the peripheral parameter to be adjusted may be the movement speed of the game character.

[0054] In this embodiment, the pressure sensor array is installed in the pressure sensing area of ​​the target peripheral according to a preset arrangement design. The arrangement design of the pressure sensor array needs to consider four aspects, including sensor distribution density, sensor layout rules, sensor sensing area and sensor sub-area mapping; among which:

[0055] Sensor distribution density: The distribution density of the pressure sensor array affects the accuracy of pressure perception. Generally speaking, the denser the sensor distribution, the more subtle pressure changes can be captured. However, cost and complexity factors must also be considered to find a suitable distribution density.

[0056] Sensor layout rules: The layout of the pressure sensor array includes grid, ring and irregular forms. Different layout forms are suitable for different peripherals. For example, the grid layout is suitable for peripherals that need to sense the pressure distribution of the entire contact area, such as touch screens. The ring layout is suitable for applications that need to sense changes in the grip pressure, such as mice and game controllers. Irregular layouts can be designed according to specific shapes, such as medical rehabilitation equipment.

[0057] Sensor sensing area: The size of the pressure sensor sensing area affects the pressure resolution. In this embodiment, the size of the sensing area of ​​each pressure sensor also needs to be reasonably designed. A sensing area that is too large may reduce the pressure resolution, while a sensing area that is too small will increase the number of pressure sensors and increase the cost. It needs to be determined based on the actual application scenario.

[0058] Sensor area mapping: map the pressure sensing area to the functional parameters of the peripheral. In this embodiment, in addition to the layout of the pressure sensor itself, it is also necessary to map the pressure sensing area to the functional parameters of the peripheral. For example, when the target peripheral is a mouse, the pressure in the left area of ​​the mouse can be mapped to sensitivity adjustment, and the pressure in the right area of ​​the mouse can be mapped to scroll wheel control. When the target peripheral is a game controller, the pressure in the thumb area can be mapped to the movement speed of the game character, and the pressure in the index finger area can be mapped to actions such as firing / jumping.

[0059] In this embodiment, the arrangement design method of the pressure sensor array includes:

[0060] Determine the pressure sensor array distribution density according to the relationship between the preset pressure sensing accuracy and the pressure sensor array distribution density, and the pressure sensing accuracy required by the target peripheral device;

[0061] Design the layout of the pressure sensor according to the actual shape and usage requirements of the target peripheral device; the layout of the pressure sensor array includes grid, ring and irregular forms;

[0062] Determine the size of the sensing area based on the pressure resolution requirements of the application scenario.

[0063] In this embodiment, by reasonably designing the density, layout, sensing area and mapping relationship of the sensor array with parameters, the potential of pressure sensing technology can be fully utilized to provide a sophisticated and natural pressure control experience for different types of peripherals.

[0064] The present invention uses a highly sensitive pressure sensor array that can accurately sense the user's tiny pressure changes. The sensor array can obtain the pressure information of each contact point of the user during operation through dense and uniform distribution. Compared with traditional single-point pressure sensors, array sensors can more accurately capture the user's pressure distribution characteristics, providing richer data support for subsequent parameter mapping and detailed control.

[0065] Step S2, processing the pressure data by a signal processing circuit to extract pressure change information.

[0066] Specifically, first, the pressure analog signal is amplified by a signal processing circuit to increase the signal strength. The amplified pressure analog signal is filtered to remove noise and interference in the pressure analog signal. Then, the amplified and filtered pressure analog signal is converted into a pressure digital signal. Finally, the pressure change information is extracted from the pressure digital signal.

[0067] The signal processing circuit can also analyze and process the pressure simulation signal, identify the user's pressure operation mode, and provide more accurate input for the parameter mapping algorithm.

[0068] Step S3, obtaining the peripheral parameter adjustment value corresponding to the pressure change information according to the pressure change information and a preset pressure-parameter mapping relationship.

[0069] In actual operation, when the user operates the peripheral device, he applies different intensities of pressure to the peripheral device. At this time, the pressure sensor array will detect the corresponding pressure data and output a pressure analog signal. The signal processing circuit converts the pressure analog signal into a pressure digital signal, extracts the pressure change information, and obtains the peripheral parameter adjustment value corresponding to the pressure change information according to the pressure change information and the preset pressure-parameter mapping relationship, and adjusts the peripheral parameters of the target peripheral device according to the peripheral parameter adjustment value.

[0070] In a preferred embodiment of the present invention, the present invention designs an intelligent and customizable pressure-parameter mapping relationship for different types of peripherals. By analyzing the control requirements of various types of peripherals, a mapping relationship between pressure input and peripheral parameter adjustment is established. For example, when the target peripheral is a mouse, the pressure input can be mapped to the adjustment of the mouse sensitivity. When the target peripheral is a game controller, the pressure input can be mapped to the control of the movement speed of the game character.

[0071] The parameter mapping algorithm provided by the embodiment of the present invention can not only realize the basic pressure-parameter correspondence, but also dynamically adjust the parameter mapping rules according to the user's usage preferences, thereby improving the naturalness and applicability of the interaction. Specifically, when the target peripheral is a game controller, an instant mapping confirmation key is set on the surface of the game controller, for example, the mapping confirmation key is set in the little finger area, and when the mapping confirmation key is pressed, the mapping adjustment program is entered. At this time, if it is in the control scene of the game character's movement speed, the game character's movement speed is adjusted by rolling the roller to make it larger or smaller. After the adjustment is completed, the mapping confirmation key is released, the mapping adjustment program is ended, and the adjusted game character movement speed is used as the adjusted peripheral parameter. In this embodiment, through interactive methods such as instant mapping confirmation keys and roller adjustment, the user can adjust the mapping relationship without interrupting the current task. It can be understood that the optimized pressure-parameter mapping relationship can be extended to peripherals in other fields, such as medical rehabilitation equipment, robot remote control equipment, etc.

[0072] In a preferred embodiment of the present invention, the pressure-parameter mapping relationship described in step S3 includes a mapping relationship between pressure magnitude and parameter, and a mapping relationship between pressure direction and parameter.

[0073] Specifically, the pressure is proportional to the parameter adjustment range. The greater the pressure applied by the user, the greater the adjustment range of the corresponding peripheral parameter. For example, when the target peripheral is a mouse and the peripheral parameter to be adjusted is the mouse sensitivity, the mouse sensitivity increases with the increase of pressure.

[0074] The pressure direction corresponds to the parameter adjustment direction. Different directions (angles) of pressure applied by the user will be mapped to different parameter adjustment directions. For example, when the target external device is a mouse, applying pressure to the left corresponds to moving the mouse to the left, and applying pressure to the right corresponds to moving the mouse to the right.

[0075] In this embodiment, the pressure sensor array can sense the pressure and pressure angle applied by the user to the peripheral device. According to the pre-set pressure-parameter mapping relationship, different pressure inputs can be converted into corresponding peripheral parameter adjustments. The present invention can achieve more natural and intuitive pressure control through a sophisticated pressure-parameter mapping design. The user only needs to apply pressure of different angles and strengths as needed, and the system can make corresponding parameter adjustments, greatly improving the flexibility and accuracy of the interaction.

[0076] In a preferred embodiment of the present invention, a plurality of pressure sensing areas may be set on the surface of the target peripheral device, and each pressure sensing area corresponds to a different peripheral device parameter.

[0077] In the actual application scenario of controlling peripheral parameters through pressure sensing, this embodiment takes the target peripheral as a game controller as an example to illustrate that different pressure inputs can be used to independently control multiple parameters such as game character movement speed and perspective control, thereby achieving richer pressure interaction.

[0078] Specifically, multiple pressure sensing areas are set on the game controller, and each area corresponds to different game parameters. For example, a pressure sensing point for controlling the moving speed of the game character is set in the thumb sensing area, and a pressure sensing point for controlling the game perspective is set in the index finger sensing area. In actual operation, the user places the thumb on the thumb sensing area of ​​the game controller and applies different amounts of pressure to control the moving speed of the character. The greater the pressure, the faster the character moves; the smaller the pressure, the slower the character moves. The user places the index finger on the index finger sensing area of ​​the game controller and controls the movement of the game perspective by changing the direction and amount of the applied pressure.

[0079] In this embodiment, through this differentiated pressure-parameter mapping design, users can independently control multiple parameters such as character movement and perspective control through different pressure inputs in the same game, greatly improving the flexibility and accuracy of game control. This pressure interaction method can also enhance the user's immersion and operating experience.

[0080] In a preferred embodiment of the present invention, the method for adjusting peripheral parameters based on pressure sensing control provided by the present invention further includes:

[0081] The pressure change information and the peripheral parameter adjustment value are fed back to the user through visual feedback or tactile feedback.

[0082] Specifically, the system will provide real-time feedback to the user on current pressure change information and parameter adjustment values ​​through visual feedback (such as screen display) and tactile feedback (such as vibration), thereby enhancing the user's operational perception.

[0083] In terms of visual feedback, the pressure change information and parameter adjustment values ​​are displayed in real time on the display screen attached to the peripheral or the connected computer screen. The pressure change information includes the pressure applied by the user and the pressure distribution diagram. This intuitive visual presentation helps users quickly understand the current operation status and make corresponding adjustments to subsequent operations.

[0084] In terms of tactile feedback, depending on the size and changes in the pressure applied by the user, the peripherals will allow the user to feel the changes in pressure through vibration feedback, force feedback, etc., thereby enhancing the sense of reality and immersion of the operation.

[0085] In this embodiment, visual feedback and tactile feedback can also be combined to form a multi-modal interactive feedback system. For example, in game control, when the user adjusts the character's movement speed through the pressure sensor, not only will the speed value change be displayed on the screen, but the handle will also produce a corresponding vibration effect according to the speed change. Multi-modal interactive feedback can not only improve the user's operation perception, but also help the user better understand the system's response logic and enhance the overall interactive experience.

[0086] It is understandable that the present embodiment can also provide feedback to the user of the current pressure state and peripheral parameter changes by means of auditory feedback, for example, by providing feedback to the user of pressure change information or peripheral parameter adjustment values ​​by means of sound prompts or voice announcements.

[0087] In a preferred embodiment of the present invention, the peripheral parameter adjustment method based on pressure sensing control provided by the present invention can not only directly control the peripheral parameters through the pressure sensor array, but also transmit the pressure data output by the pressure sensor array to other related devices through wireless transmission, thereby realizing linkage control of multiple devices.

[0088] In this embodiment, a pressure sensor array is arranged to be connected to a receiver device via a wireless communication device, and the receiver device is used to control its associated target peripheral device;

[0089] Accordingly, in step S1, after sensing the pressure change applied by the user to the pressure sensing area of ​​the target peripheral device through the pressure sensor array and acquiring the pressure data, the peripheral parameter adjustment method based on pressure sensing control further includes:

[0090] wirelessly transmits pressure data to a receiver device;

[0091] The receiver device generates a parameter adjustment instruction according to the received pressure data, and adjusts the peripheral parameters of the target peripheral device according to the parameter adjustment instruction.

[0092] Specifically, the pressure data output by the pressure sensor array is transmitted to the receiver device through the wireless communication device (such as WIFI device) built into the peripheral. The receiver device can be an independent control module or the main control system of other devices. The receiver device will trigger the corresponding operation instructions according to the received pressure data, thereby controlling the behavior of the associated device.

[0093] For example, when the target peripheral is a game controller and the receiver device is a computer host, the player uses the game controller to control the movement of the character, and the pressure sensor array is installed on the game controller. At the same time, the wireless communication device built into the game controller will also transmit the pressure data output by the pressure sensor array to the computer host. The computer host adjusts the display parameters of the game screen according to the pressure data, such as perspective zoom, picture effects, etc. This can not only control the movement of the character, but also adjust the game screen synchronously to enhance the player's immersion.

[0094] In another application scenario, for example, the target peripheral is a remote control for home appliances, the surface of the remote control is equipped with a pressure sensor array, and the receiver device is a central control system. Users control home appliances through the remote control, and the remote control can not only directly control the corresponding home appliances, but also transmit the pressure data to the central control system through the built-in wireless communication device after the pressure sensor array senses the pressure changes applied by the user on the remote control. The central control system adjusts the status of other devices such as home lighting and temperature control according to the pressure data to achieve more coordinated intelligent control.

[0095] In this embodiment, the pressure sensor array realizes the linkage control of multiple devices through the coordinated work of wireless signal transmission and receiver devices, providing users with a more intelligent and convenient interactive experience.

[0096] The actual operation of the peripheral parameter adjustment method based on pressure sensing control provided by the present invention is described below through two specific application scenario embodiments, including embodiment 1 and embodiment 2:

[0097] Embodiment 1:

[0098] Gamepad pressure control

[0099] When the present invention is applied to control the relevant parameters of a game controller, the pressure input in different areas can be mapped to the linkage control of multiple relevant parameters. For example:

[0100] The pressure in the thumb area is mapped to the speed at which the character moves;

[0101] The pressure in the index finger area is mapped to the sensitivity of visual angle movement;

[0102] The pressure of the middle finger area is mapped to the action triggers such as firing / jumping;

[0103] When the user holds the game controller and applies different intensities of pressure to these three areas at the same time, the system can adjust the character's movement speed, viewing angle sensitivity and action triggering according to the pressure input, making the overall control of the game character more coordinated and smooth. As a result, users do not need to frequently switch between different operations, but can control multiple game parameters at the same time through a continuous pressure input, greatly improving the operating efficiency and gaming experience.

[0104] Embodiment 2:

[0105] Pressure control in medical rehabilitation equipment

[0106] When the present invention is applied to relevant parameters of medical rehabilitation equipment, pressure sensing technology can be applied to the rehabilitation training of patients to help improve the training effect and experience.

[0107] For example, the peripheral parameters to be adjusted in this embodiment are related parameters of a medical rehabilitation device, and the medical rehabilitation device is a gait robot for lower limb muscle rehabilitation training. Traditional gait robots usually adopt a set fixed gait mode and cannot be flexibly adjusted according to the actual situation of the patient.

[0108] The embodiment of the present invention utilizes pressure sensing technology, and the gait robot can better sense the distribution and changes of pressure applied to the soles of the feet by the patient during training.

[0109] Specifically, this embodiment deploys a pressure sensor array on the soles of the gait robot, which can fully capture and record the pressure data of the patient's feet during walking or standing.

[0110] The collected pressure data is analyzed in real time through the signal processing circuit built into the medical rehabilitation equipment, and the patient's gait characteristics, including stride length, step frequency, support time, etc., are identified through complex algorithm analysis.

[0111] The intelligent algorithm will automatically adjust the robot's gait parameters, such as stride length, step frequency, support time, etc., based on pressure data to better match and assist the patient's actual gait.

[0112] At the same time, the gait robot can also provide patients with feedback on the current pressure distribution and gait adjustment through visual feedback (screen display) and tactile feedback (vibration). As a result, patients can perceive their gait more intuitively and adjust the pressure applied to their feet in real time, so as to actively cooperate with the robot's gait adjustment and complete more targeted rehabilitation training.

[0113] Compared with the traditional fixed gait training mode, the adaptive gait training based on pressure sensing of the present invention can not only better meet the actual rehabilitation needs of patients, but also enhance the active participation of patients and improve the pertinence and effect of training.

[0114] This pressure sensing technology also has broad application prospects in other medical rehabilitation equipment such as wheelchairs and prostheses, and can provide patients with more intelligent and humane assistance and training.
