Display Input Mapping for Keyboard-Mouse Touch Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Players transitioning from PC gaming to mobile platforms face discomfort with touchscreen controls due to lack of flexibility in mapping keyboard/mouse functions, small screen size causing visual fatigue, and the need for connecting mobile devices to computers for control.
Innovation Solution
A display system that stores a correspondence between keyboard-mouse commands and touch operations, allowing direct control of touch devices via keyboard and mouse without a computer, enabling customizable input mapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If keyboard and mouse are connected directly to the display without a computer, then equipment cost is reduced and control convenience is improved, but the display must perform additional signal processing functions increasing device complexity
Solution Approach 1:
The display is designed to perform multiple functions: not only displaying visual information but also receiving keyboard-mouse signals, storing command correspondences, and outputting touch signals to control the touch device. This multi-functionality eliminates the need for a separate computer, reducing equipment cost while improving control convenience.
Solution Approach 2:
The display acts as an intermediary device between the keyboard-mouse input and the touch device. It receives keyboard-mouse signals, processes them through stored correspondences, and converts them into touch device control signals, thereby enabling control without a computer while managing the complexity through dedicated processing functions.
2Adaptability or versatility
If customizable mapping between keyboard-mouse commands and touch operations is implemented, then adaptability and playability are improved, but memory and processing requirements increase
Solution Approach 1:
The display stores multiple pre-defined correspondences between keyboard-mouse commands and touch operations in its memory before actual use. When a user wants to control the touch device, the appropriate pre-stored correspondence is selected and applied, eliminating the need for real-time complex mapping calculations and reducing processing requirements.
Solution Approach 2:
The system allows users to select from different pre-stored correspondence sets, effectively changing the mapping parameters between keyboard-mouse commands and touch operations. This provides adaptability and customization without requiring the system to dynamically generate complex mappings, thus managing memory and processing requirements efficiently.
3Ease of manufacture
If the display processes and converts keyboard-mouse signals to touch signals, then the need for a computer is eliminated reducing equipment cost, but the display's processing burden increases
Solution Approach 1:
The display is designed to perform multiple functions including signal reception, correspondence storage, signal conversion, and touch device control. By integrating these functions into the display, the system eliminates the need for a separate computer, reducing overall equipment cost while distributing the processing burden across dedicated display components.
