Touch Screen Matrix Key Mapping for Recording Controller Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording software controllers with physical keys lack customization and flexibility, requiring multiple PVC functional films for different software types and not allowing users to adjust key functions easily.
Innovation Solution
A touch key design method for a touch screen that divides the screen into areas to form a matrix, reads a function mapping table to determine key functions, and updates display content in real time based on touch signals and software state changes, allowing users to customize key positions and functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If physical keys such as silicone keys are used, then the controller has a fixed key layout, but the key function cannot be changed and hand feeling is poor
Solution Approach 1:
The patent replaces physical mechanical keys with a touch screen interface. The touch screen displays virtual keys that respond to touch inputs, eliminating the need for physical silicone keys while providing customizable key functions through software configuration. This substitution maintains tactile feedback through visual and haptic responses while enabling full customization of key layouts and functions.
2Adaptability or versatility
If multiple PVC functional films are used for different recording software types, then each software can have its own key mapping, but the device complexity increases and users must change films frequently
Solution Approach 1:
The patent implements a universal touch screen interface that can adapt to multiple recording software types through software-based key mapping configuration. Instead of requiring different physical PVC films for different software, the system uses a single touch screen with programmable key functions that can be customized for each software type, eliminating the need for multiple physical films and reducing device complexity.
Solution Approach 2:
The patent introduces dynamic key mapping where the touch screen key functions can be changed and customized in real-time through software configuration. The key layout and functions are not fixed but can be dynamically adjusted to match different recording software requirements, allowing users to switch between software types without changing physical films.
3Adaptability or versatility
If fixed physical keys are used, then the manufacturing is simple, but users cannot customize and adjust the function of each key
Solution Approach 1:
The patent replaces fixed physical keys with a touch screen interface that allows software-based customization. The manufacturing process becomes simpler as it eliminates the need for multiple physical key components and their associated assembly steps. The customization capability is achieved through software programming rather than physical manufacturing variations.

AI summary
The present disclosure discloses a touch key design method based on a touch screen, wherein a plastic part is placed on a touch screen, so that the touch screen is equally divided into a plurality of (such as 4×4) areas with the same size. In this way, the touch screen can be regarded as a plurality of (such as 4×4) matrix touch keys. When one of the touch keys is touched by hand, an MCU (a main control unit of a recording software controller) determines which touch key is pressed through the X and Y coordinate values returned by the touch screen, and then controls the corresponding functions. On the touch screen, not only the function name of the recording software corresponding to each touch key is displayed, but also the state of pressing or releasing the touch key and the state about whether the corresponding function on the recording software is activated or non-activated can be displayed in real time. In addition, users are allowed to change the position and the function name of each touch key in the touch screen randomly according to their own usage habits and preferences.
