Touchpad Coordinate Mapping for Multi-Function Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touchpad technologies are inefficient due to each area corresponding to only one type of instruction or input content, limiting their functionality and universality across different countries and applications, and failing to seamlessly switch between mouse and keyboard functions.
Innovation Solution
Divide the touchpad into multiple areas by coordinate points, create a database correlating these areas with key code values and contents, and enable switching between keyboard and mouse functions, allowing each area to correspond to multiple key code values and enable the input of various contents, including system shortcuts and macro commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If each touchpad area corresponds to only one instruction or one input content, then the touchpad operation is simple, but the touchpad efficiency and functionality are limited
Solution Approach 1:
The patent makes each touchpad area correspond to multiple key code values and multiple types of input content simultaneously. By establishing a database that maps each coordinate area to multiple key codes and contents, the touchpad gains multi-functionality where a single area can trigger different inputs based on context, thereby improving efficiency without complicating user interaction
Solution Approach 2:
The patent changes the parameter of area-content correspondence from one-to-one to one-to-many. By modifying the data structure in the database to allow each coordinate area to associate with multiple key code values and multiple input contents, the system enables richer input capabilities while maintaining the same physical touchpad interface
2Reliability
If the touchpad uses fixed keyboard layouts for different countries, then the localization is accurate, but the universality and adaptability across different countries are poor
Solution Approach 1:
The patent creates a universal touchpad system that can adapt to multiple country-specific keyboard layouts through a single device. The database stores multiple key code mappings for each area, allowing the system to select the appropriate layout based on the detected operating system language, thus achieving both accuracy for each country and universality across countries
Solution Approach 2:
The patent makes the keyboard layout dynamic by detecting the operating system's language settings and automatically switching between different key code mappings. This dynamic adaptation allows the same touchpad to provide accurate localized input for different countries without requiring physical reconfiguration
3Ease of operation
If the touchpad shields mouse function to enable keyboard function, then the keyboard input can be achieved, but the switching process is inconvenient and time-consuming
Solution Approach 1:
The patent merges the mouse function and keyboard function into a single unified touchpad operation mode. Instead of shielding one function to enable the other, the system combines both capabilities by allowing coordinate-based input that can trigger either mouse actions or keyboard inputs based on the configured database mappings, eliminating the need for function switching
Solution Approach 2:
The patent performs preliminary configuration by pre-setting the database with multiple key code values and input contents for each touchpad area. This preliminary action enables the system to directly process coordinate inputs as keyboard commands without requiring runtime function switching, thus saving time
4Productivity
If the touchpad supports only fast information inputting, then the ID number inputting efficiency is improved, but the system shortcut key inputting and macro command inputting capabilities are lacking
Solution Approach 1:
The patent extends the touchpad functionality to support multiple types of input content including system shortcut keys, macro commands, and regular text input. The database is configured to map touchpad areas to various input types, making the device universally applicable for different input needs beyond just fast ID number entry

AI summary
The invention discloses a touchpad-based fast information input interaction method and an input interaction system thereof. The method comprises: S1, dividing the touchpad into a plurality of areas by coordinate points; S2, creating a database containing the correlation between the touchpad coordinate areas and key code values and a database containing the correlation between the key code values and stored contents, wherein each touchpad coordinate area corresponds to one or more key code values; S3, switching the touchpad into keyboard function, wherein the keyboard function and the mouse function of the touchpad can be switched therebetween; obtaining, by operating system, a trigger action signal on the touchpad and the coordinate information of the corresponding position on the touchpad where the trigger action signal has been generated; S4, determining the key code value used, searching the corresponding content from the database, inputting the content in the position of the cursor or executing a corresponding instruction. By utilizing each touchpad coordinate area corresponding to one or more key code values, the present invention can further improve the utilization of the touchpad.
