Description

Technical Field

[0001] This invention relates to the field of computer input device technology, and more specifically to a mouse with adjustable DPI and a method for adjusting DPI. Background Technology

[0002] In esports, mouse movement speed (DPI) settings are crucial for user precision and efficiency. DPI (Dots Per Inch) is a common parameter measuring the sensitivity or speed of pointing devices such as computer mice. Specifically, it represents the number of pixels the cursor moves on the screen for every inch (approximately 2.54 centimeters) the mouse moves on a physical surface. For example, when the mouse is set to 1600 DPI, the cursor will move 1600 pixels for every inch the mouse physically moves. A higher DPI value means a shorter physical distance the cursor needs to move to cover the same distance on the screen, resulting in faster mouse movement and higher sensitivity; conversely, a lower DPI value results in slower mouse movement, which is beneficial for precise cursor positioning.

[0003] Different game scenarios (such as precise sniping and rapid perspective switching) require different DPI values. Current esports mice typically offer a limited number of preset DPI levels (e.g., 3-5) for users to switch between. This discrete setting method has significant drawbacks: firstly, it limits the user's continuous exploration of DPI values, making it impossible to find the optimal setting amidst subtle DPI changes; secondly, after switching levels, users cannot intuitively and quickly know the specific DPI value, easily leading to confusion during intense gameplay. Some high-end mice allow setting more levels or custom DPI values ​​through accompanying software, but the operation process is cumbersome, requiring users to click and input values ​​multiple times within the software interface, failing to meet the needs of rapid, dynamic adjustments in games. Furthermore, existing mice lack convenient recording and labeling functions for frequently used DPI settings, making it difficult for users to effectively review and manage successful settings.

[0004] Therefore, there is an urgent need in this field for a mouse solution that can break through the limitations of fixed DPI levels, achieve flexible and seamless switching of DPI values, and have real-time status display and setting memory functions. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a mouse with adjustable DPI values ​​and a method for adjusting DPI accordingly, allowing users to adjust DPI more conveniently and quickly. This mouse can adjust DPI multiple times at custom intervals, based on a specific coordinate DPI value, without being limited by the number of DPI settings. This enables continuous and scalable exploration of DPI values ​​and provides real-time feedback of the current DPI value on the display screen, greatly facilitating users to quickly use and record optimal DPI settings in different game scenarios. To achieve the above-mentioned objectives, this invention adopts the following technical solution: In a first aspect, the present invention provides a mouse with an adjustable DPI value, comprising a base, a housing, and a sensor disposed inside the housing, wherein the improvement is that it further comprises: A DPI adjustment component is disposed on the housing and is used to generate a DPI adjustment signal; The control module is located inside the housing and is electrically connected to the DPI adjustment component and the sensor; The control module stores preset coordinate DPI values ​​and unit step values. The control module is configured to: respond to the trigger signal of the DPI adjustment component, adjust the DPI value incrementally or incrementally according to the unit step value based on the coordinate DPI value to obtain the target DPI value, and control the sensor to switch to the target DPI value.

[0006] Optionally, the mouse with adjustable DPI value according to the present invention further includes a recording button, which is disposed on the housing and electrically connected to the control module. The control module saves the current DPI value to the storage unit according to the trigger signal of the recording button.

[0007] Optionally, the mouse with adjustable DPI value according to the present invention further includes a display module disposed on the housing, wherein the control module drives the display module to display the current DPI value or synchronously display the current DPI value and its corresponding custom named text.

[0008] Optionally, in the mouse with adjustable DPI value according to the present invention, the control module is further configured to transmit at least one of the current DPI value, the preset coordinate DPI value, and the unit step value to external software.

[0009] Optionally, in the mouse with adjustable DPI value according to the present invention, the DPI adjustment component consists of independent up-level and down-level buttons.

[0010] Optionally, in the mouse with adjustable DPI value according to the present invention, the DPI adjustment component is a scroll wheel, which generates an increasing signal when rotating in the forward direction and a decreasing signal when rotating in the reverse direction; the scroll wheel is a smooth scroll wheel or a scroll wheel with a jolt setting; when the scroll wheel is a scroll wheel with a jolt setting, a single jolt setting corresponds to one increase or decrease in the unit step value.

[0011] In a second aspect, the present invention provides a DPI adjustment method, applied to a mouse with an adjustable DPI value as described in any one of the first aspects, comprising the following steps: Preset steps: The control module receives the coordinate DPI value and unit step value sent by the external device and saves them to the storage unit; Execution steps: The control module responds to the trigger signal of the DPI adjustment component, calculates the target value after adjustment according to the coordinate DPI value and the unit step value, and adjusts the DPI value of the sensor.

[0012] Optionally, the DPI adjustment method according to the present invention further includes a recording step: When the control module receives the trigger signal from the record button, it extracts the real-time DPI value at the current moment, forms a DPI record value, and saves it to the storage unit; or When the control module receives the trigger signal of the record button, it extracts the real-time DPI value at the current moment, accepts the custom named text, establishes an association between the custom named text and the corresponding DPI record value, and saves them together to the storage unit.

[0013] Optionally, the DPI adjustment method according to the present invention further includes a display step: The control module drives the display module to synchronously update and display the target value; or When the target value matches the DPI record value of the custom-named text associated with it in the storage unit, the control module drives the display module to display the target value and its corresponding custom-named text.

[0014] Optionally, according to the DPI adjustment method of the present invention, the preset step further includes a coordinate value selection step: The control module retrieves the list of saved DPI record values ​​from the storage unit and updates the selected DPI record value with the new coordinate DPI value.

[0015] Optionally, the DPI adjustment method according to the present invention further includes an output step: The control module transmits at least one of the following status information to external software: the current DPI value, the coordinate DPI value, and the unit step value.

[0016] The DPI adjustment scheme of this invention is significantly more convenient to operate than existing technologies: users only need to input the coordinate DPI value and unit step value through the accompanying software to complete the configuration of all core parameters and put it into use directly. Specifically, the beneficial effects include: 1. By setting the connection relationship between the control module and other components, customizable step adjustment based on the coordinate DPI value is realized, breaking through the limitations of the traditional mouse's fixed and limited range, allowing users to continuously and precisely explore the DPI value most suitable for the current usage scenario; 2. By setting a display module on the mouse shell, the current DPI value can be displayed in real time and intuitively, which solves the problem that users cannot quickly confirm the setting value after switching and avoids operation confusion; 3. By adding a record button and related methods, users can easily save successful DPI settings in specific scenarios, and can customize their names and recall them later, greatly improving the reusability and management efficiency of the settings.

[0017] In contrast, the DPI setting process for conventional mice on the market is cumbersome and time-consuming. Regardless of how many fixed DPI levels are provided, users need to pre-determine multiple target DPI values, manually calculate them, and then input them one by one into the corresponding level. If one DPI value needs to be adjusted later, the values ​​of the other related levels need to be modified simultaneously, requiring re-entry of each level, which is very inefficient.

[0018] This invention's adjustable DPI mouse is adaptable to various usage scenarios: whether it's for office workers using it at home after get off work, for temporary use in an internet cafe during short breaks, or for professional gamers' daily training, users only need to input two parameters—the coordinate DPI value and the unit step value—after opening the accompanying software to quickly achieve the DPI setting that suits their needs, eliminating the need for tedious adjustments and input over ten minutes or more. Furthermore, in actual use, users are not limited by the number of fixed DPI levels and can freely explore different mouse movement speeds (DPI values). The recording function also saves the adapted DPI settings, preventing the loss of muscle memory training results due to lost settings. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] A mouse with adjustable DPI value according to an embodiment of the first aspect of the present invention, such as Figure 1As shown, the device includes a base 1, a housing 2, and a sensor disposed inside the housing 2. It also includes: a DPI adjustment component disposed on the housing 2 for generating a DPI adjustment signal; and a control module 5 disposed inside the housing 2, electrically connected to the DPI adjustment component, the display module 4, and the sensor. The control module 5 stores preset coordinate DPI values ​​and unit step values. The control module 5 is configured to: respond to a trigger signal from the DPI adjustment component, adjust the DPI value incrementally or incrementally according to the unit step value, based on the coordinate DPI value, to obtain a target DPI value, and control the sensor to switch to the target DPI value.

[0025] Existing mice typically require multiple fixed DPI levels to be preset in the accompanying software, and users must input the specific value for each level before starting use. This setting method is inefficient, and if a fine-tuning of one level is needed later, other related levels often need to be modified simultaneously, lacking flexibility. This invention effectively solves the above problems by providing an innovative mouse structure with adjustable DPI values. The mouse includes a base and an outer shell that constitutes the main structure of the mouse. The base refers to the bottom part of the mouse that directly contacts a supporting surface such as a desktop during use, typically supporting the mouse feet and sensor optical window; the outer shell covers all external areas of the mouse that the user can touch and operate during use, including the front, sides, and top, excluding the base. An internal control module is installed in the mouse, which stores preset coordinate DPI values ​​and unit step values.

[0026] like Figure 2 As shown, users can set initial parameters via the accompanying software connected to the computer. Users can input a base value (e.g., 1517) in the coordinate DPI setting area and a step value (e.g., 248) in the unit step value setting area. These parameters are sent and stored in the storage unit of control module 5. During the game, the interaction relationships between the various modules are as follows: Figure 3As shown, when the user issues an increment command to the DPI adjustment component, the control module 5 responds to this trigger signal and performs the following calculation: Target DPI value = Current coordinate DPI value (1517) + Unit step value (248) = 1765. The control module 5 then controls the sensor to switch the DPI to 1765. Another increment command is issued, and the DPI value becomes 2013. Similarly, a decrement command is issued, and a decrement operation is performed. This achieves step adjustment with 1517 as the coordinate and 248 as the interval. During this adjustment process, the "coordinate DPI value" is the instantaneous calculation origin for each step adjustment; while the "target DPI value" is the actual working value that the sensor needs to immediately switch to, calculated by incrementing or decrementing from the instantaneous coordinate DPI value as the origin after each adjustment command is triggered. After each effective adjustment operation is completed, the target DPI value generated by this adjustment will be updated to the new coordinate DPI value, serving as the new calculation origin for the next adjustment operation.

[0027] Users only need to input these two core parameters (coordinate DPI value and unit step value) in the software to quickly establish a DPI switching scheme that is suitable for their personal usage habits and can be adjusted in infinite steps, greatly simplifying the initial setup process. The unit step value can also be described in the software settings interface as "DPI interval value" or other names that can clearly represent the DPI change range corresponding to each adjustment operation, and this invention does not limit it in this way.

[0028] Furthermore, such as Figure 1 As shown, the mouse also includes a recording button 6, which is disposed on the housing 2 and electrically connected to the control module 5. The control module 5 saves the current DPI value to the storage unit based on the trigger signal of the recording button 6. By setting a recording button on the mouse, users can quickly mark successful DPI settings during exploration, facilitating subsequent retrieval and management.

[0029] Furthermore, the mouse also includes a display module 4, which is disposed on the outer shell 2. The control module drives the display module 4 to display the current DPI value or synchronously display the current DPI value and its corresponding custom-named text. Figure 2 , 3 As shown, when the control module responds to the incremental adjustment signal and switches the sensor DPI value to 1765, it will simultaneously drive the display module to display "1765". If the user has already marked this value with a name (such as "Sniper Mode") by pressing the record button, the display module can simultaneously display "1765" and the "Sniper Mode" label. This design allows users to intuitively identify the applicable scenario for the current DPI setting through a combination of numerical values ​​and semantic labels, significantly improving operational clarity and setting management efficiency.

[0030] Display module 4 can be an OLED display, LCD display, digital tube array, or other components capable of displaying numbers or text; this invention does not limit its application to these components. The display methods of display module 4 include, but are not limited to: alternating or merging numerical values ​​and text within a single display area, or displaying numerical values ​​and text separately in different areas. This invention does not limit the display layout; any display scheme capable of synchronously feeding back DPI values ​​and associated text falls within the scope of protection of this invention.

[0031] like Figure 2 As shown, in the software interface, users can also select a saved DPI record value (e.g., 1517, named "Sniper Mode") from the DPI record list area and directly select it as the new coordinate DPI value. Subsequent adjustments will be made based on 1517 as the new baseline. This function allows users to quickly recall personalized DPI settings that have been verified in actual combat or developed through specialized training, avoiding repetitive exploration.

[0032] Furthermore, the control module is configured to transmit at least one of the following status information—the current DPI value, the preset coordinate DPI value, and the unit step value—to external software. Here, the external software refers to an application or driver running on a computing device (such as a personal computer or game console) that is communicatively connected to the mouse. This design allows the mouse's real-time status information to be acquired and utilized by a third-party application running on the computing device. For example, after receiving this data, the external software can present it to the user in real-time through a computer screen, an OSD (On-Screen Display), or other methods that are easier for the user to observe. This allows users to intuitively and conveniently obtain key information such as the current DPI value in immersive scenarios such as games or full-screen applications without having to look down at the small display on the mouse, greatly improving the intuitiveness of operation and the efficiency of information acquisition.

[0033] Furthermore, the DPI adjustment component consists of an independent up-shift button 31 and a down-shift button 32, located on the same side of the housing 2. The specific shape, size, and distribution of the up-shift button 31 and down-shift button 32 can also vary; any button shape and layout capable of generating incremental or decremental trigger signals falls within the scope of this invention. The up-shift button 31 and down-shift button 32 can also be configured as multi-function buttons. For example, their function can be switched between DPI adjustment and other designated functions (such as multimedia playback / pause control, copy / paste command triggering, or browser forward / backward functions) through software settings, specific gesture operations, or other operations. When configured for other functions, their trigger signals will no longer drive the step adjustment of DPI. Furthermore, the display module and adjustment component are arranged close together, allowing the user to quickly and directly obtain visual feedback after triggering the button, further reducing distraction during operation, especially suitable for competitive game scenarios requiring high concentration. Preferably, the upshift button and the downshift button can be located on the thumb side of the outer shell 2, which conforms to the ergonomic principle, allowing users to perform blind operation without changing their hand posture when holding the mouse, significantly improving the convenience and response speed of operation.

[0034] Optionally, the DPI adjustment component can also be a scroll wheel 33. The scroll wheel 33 generates an increasing signal when rotating forward and a decreasing signal when rotating backward. The scroll wheel 33 can be a smooth scroll wheel or a scroll wheel with tactile feedback. When the scroll wheel has tactile feedback, each tactile feedback level corresponds to one increase or decrease in the unit step value. The scroll wheel can be used as a normal function scroll wheel by default. It is only configured as a DPI adjustment component when the DPI adjustment function is enabled via software or other means. When using a scroll wheel with tactile feedback, each tactile feedback level corresponds to one increase or decrease in the unit step value: scrolling forward one level generates an increasing signal, and scrolling backward one level generates a decreasing signal. This tactile feedback design provides clear tactile feedback to the user, allowing them to clearly perceive that each scrolling operation accurately triggers a change in level, effectively avoiding adjustment errors caused by over-scrolling or unclear operation, and improving the accuracy and feel of the adjustment.

[0035] According to a second aspect embodiment of the present invention, the DPI adjustment method is executed by the control module 5 inside the mouse, in conjunction with the DPI adjustment component, sensor, display module 4, recording button 6, and storage unit. Specifically, it includes... Figure 4 The following steps are shown: Pre-set steps: The user sets a coordinate DPI value (e.g., 1517) and a unit step value (e.g., 248) through external software (running on a computer). These parameters are sent to the mouse control module 5 via USB or other means, and the control module 5 saves them to its internal storage unit. This step completes the initial configuration of the method.

[0036] Execution steps: During gameplay, when the user operates the DPI adjustment component, such as pressing the upshift button or scrolling the wheel, control module 5 immediately responds to this trigger signal. Control module 5 reads the currently effective coordinate DPI value and unit step value from the storage unit and performs mathematical calculations: target DPI value = coordinate DPI value ± unit step value ("+" corresponds to increment, "-" corresponds to decrement).

[0037] Optionally, the DPI adjustment method further includes a recording step: when the user deems the setting worth saving at any DPI value, they can press the record button 6. After receiving this signal, the control module 5 will extract the real-time DPI value at the current moment as a record and save it to the storage unit.

[0038] Optionally, the DPI adjustment method further includes a display step: the control module 5 sends a command to the sensor to switch its DPI value to the calculated (or limited) target DPI value, while simultaneously driving the display module 4 to update synchronously. Further, the control module 5 determines whether the target DPI value matches a saved DPI record value in the storage unit that is associated with a custom-named text. If the match is successful, the control module 5 drives the display module 4 to simultaneously display the target DPI value and its corresponding custom-named text (e.g., displaying "Sniper Mode" when the target value is "1517"). If no matching record value is found, the control module 5 drives the display module 4 to only display the target DPI value. In this way, the display step not only provides accurate DPI value feedback but also offers users more specific scenario prompts, greatly improving the intuitiveness and convenience of operation.

[0039] Optionally, the DPI adjustment method further includes an output step: the control module 5 transmits at least one of the following status information to external software: the current DPI value, the coordinate DPI value, and the unit step value. This step enables the external software to obtain accurate DPI status in real time and supports synchronous or secondary display on user-friendly interfaces such as computer screens and game display overlays (OSDs).

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
