Description

Technical Field

[0001] The present invention relates to electronic product control equipment, and in particular to a dual-scale electronic product precision control device and a control method. Background Art

[0002] Currently, precise cursor control in graphical user interfaces (GUIs) in the industry primarily relies on unidirectional and omnidirectional joysticks, optical mice, trackball mice, or various touch screens. While joysticks, mice, and trackballs can easily perform large-scale operations due to their reliance on the wrist or arm, they lack flexibility and sensitivity for precise control. Conversely, touch screens, while convenient for precise operations, require continuous screen movement due to their limited area when operating on a large scale.

[0003] The traditional solution to this problem is to rely on software to assist with the solution. However, due to the differences in parameters such as the resistance coefficient of each actual operating device, time-consuming calibration is required before use.

[0004] Solving the above defects can meet various needs including industrial control, art design, and home use. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention provides a dual-scale electronic precision control device.

[0006] The present invention is implemented as follows: a dual-scale electronic product precision control device: the device includes: a touch screen control module, a trackball control module, a main control module and a power supply module.

[0007] Each module has the following structure:

[0008] 1. Touch screen control module, including:

[0009] Multi-touch spherical display module, internal communication module and wireless rechargeable battery module:

[0010] The multi-touch spherical display module implements the following functions:

[0011] 1. Tactile information collection:

[0012] When the touch screen is operated, the device collects the touch track and gesture action of the finger from the multi-touch spherical display module, and transmits the finger displacement variable to the main control module through the internal communication module. The finger displacement variable will be converted into the mouse displacement variable. The mouse displacement variable can be scaled according to the preset calibration scale. If the final result exceeds the computer executable precision number, it will be adjusted accordingly. The adjustment method is as follows:

[0013] 1) Precision scaling does not affect the parameters of the mouse displacement variable direction;

[0014] 2) If the maximum value of the mouse displacement variable exceeds the executable range, the absolute value of the mouse displacement variable is limited to the maximum value;

[0015] 3) If the numerical precision exceeds the readable range, the absolute displacement is rounded down to a value where the minimum absolute displacement that can be output is zero;

[0016] 2. Optical information feedback:

[0017] The multi-touch spherical display module can provide optical feedback to finger operations through the feedback display function. The optical information content is controlled by the integrated processing module and transmitted through wireless communication. The feedback types include:

[0018] 1) Displacement feedback:

[0019] The continuous contact position change of a single finger on the touch spherical display module is fed back as a physical displacement, which is fed back in the form of an optical signal that moves from the initial position of the displacement change to the final position along a specific trajectory.

[0020] 2) Pressure feedback:

[0021] The force applied by a single finger on the touch spherical display module is fed back as pressure, and the feedback is in the form of light emission at the pressed location.

[0022] 3) Zoom feedback:

[0023] The change in relative distance between multiple finger contact points is recognized as a zoom, and the feedback is the largest triangle circumscribed circle among all contact points. At the same time, a local amplification signal is fed back to the host system (for this function to work, the controlled device must have corresponding functions, such as the magnification assist function of the Windows system);

[0024] The touch screen control module and the main control system communicate with each other through wireless communication signals between the internal communication module and the integrated wireless communication module;

[0025] The wireless rechargeable battery module provides energy supply for other modules in the touch screen control module;

[0026] 2. Trackball control module, including:

[0027] Trackball housing, optical probe;

[0028] The finger can move the trackball housing to make the trackball housing and the device roll relative to each other in all directions;

[0029] The optical probe collects the rolling data of the trackball housing and transmits it to the main control module.

[0030] 3. Main control module, including:

[0031] Integrated wireless communication module, direction lock control module, custom function button module and integrated processing module;

[0032] The integrated wireless communication module performs wireless transmission and reception with the internal communication module under the touch screen control module and the external device, obtains the input signal of the integrated processing module and transmits the feedback output signal to the corresponding device or module;

[0033] The direction lock control module is an independent control switch. When it is turned on, the direction lock function is executed. Even if the input signal of the cursor in a specific direction remains zero, the cursor can only move in this direction. The setting of the specific direction is set by the corresponding driver software of the device.

[0034] The custom function button module is an independent control switch. Through pre-set operation, the custom function button can implement the output signal of the mouse function with a specific function.

[0035] The integrated processing module integrates and calculates the data collected by the touch screen control module and the trackball control module, and transmits the feedback information and the final output information to the integrated wireless communication module.

[0036] 4. Power module, including:

[0037] Internal power supply and spherical wireless charging module;

[0038] The internal power supply provides power to the main control module, the optical probe of the trackball control module, and the spherical wireless charging module through wired connections;

[0039] The spherical wireless charging module provides power to the wireless charging battery module of the touch screen control module through wireless charging. When the wireless charging battery module obtains the power provided by the power module, it generates a continuous activation signal and sends it to the multi-touch spherical display module and the internal communication module. After receiving the activation signal, the touch screen control module is in operation.

[0040] Furthermore, based on the above device, the present invention also provides a control method for parameter acquisition and calculation output of the device:

[0041] 1. Data Collection

[0042] 1) Touch screen displacement acquisition:

[0043] The continuous contact position change of a single finger on the touch spherical display module is identified as a physical displacement S1, which is a binary polar coordinate number used to represent the displacement change;

[0044] 2) Pressure parameter acquisition of the touch screen:

[0045] The force application area of a single finger on the touch spherical display module is recognized as a pressure p, and p is converted into a pressure scale command n , , max , min ,

[0053] , min ,

[0055] , , max , i , i ,

[0054] , max , , min Parameter, and n p Depends on the preset recognizable pressure range threshold:

[0046] If the minimum threshold is set as p min , and the maximum value is p max , then:

[0047] When p min > p, n p = 1,

[0048] When p min ≤ p ≤ p max At this time, n p = (p max - p) / (p max - p min ),

[0049] When p max < p, n p = 0;

[0050] 3) Zoom parameter acquisition of the touch screen:

[0051] The relative distance change between two fingers among multiple fingers is recognized as l i (When the distance increases, l i Is recognized as a positive number, otherwise it is recognized as a negative number), l i Is converted into a zoom scale command parameter n, and n depends on the previously retained zoom scale command parameter, the zoom scale command parameter threshold, and the zoom scale x:

[0052] If the minimum threshold is set as n min , and the maximum value is n max , Is the average value of l i , n0 is the previously retained zoom scale command parameter, then:

[0053] n0 + l * x < n min At this time, n = n min ,

[0054] n min ≤ n0 + l * x ≤ n max At this time, n = n0 + l * x,

[0055] n0 + l * x > n max , n = n max ;

[0056] 4) Displacement acquisition of optical probe:

[0057] The optical probe can collect the rolling motion of the trackball shell and recognize the relative rolling motion of the trackball shell as a displacement signal S2, which is transmitted to the comprehensive processing module of the main control module. S2 is a binary polar coordinate number used to represent the displacement change.

[0058] 2. Calculation output:

[0059] 1) Displacement calculation:

[0060] The integrated processing module processes the motion information and touch information transmitted from the touch screen control module and the trackball control module, and converts them into output signals O, where O is a binary polar coordinate number representing the displacement change:

[0061] O=n*S1+n p *S2;

[0062] 2) Direction lock calculation:

[0063] After the direction lock function is activated, the integrated processing module locks the elevation increment in the polar coordinate data of O to 0 to limit the data changes of the mouse outside the restricted direction.

[0064] 3) Final output:

[0065] The output signal O is converted into the data type of ordinary mouse output in the integrated processing module as a binary polar coordinate data, and is finally transmitted to a general device to control the general device. BRIEF DESCRIPTION OF THE DRAWINGS
