Touch Mouse Simulating Keyboard Key Presses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pointing input devices like touch mice cannot replace keyboards for typing functions, requiring users to switch between devices, which is inconvenient.
Innovation Solution
A touch mouse with a touch panel and processing circuit that simulates keyboard key presses by detecting finger touches, allowing users to input keys without leaving the device, using distinct operation modes for gesture and key input functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch mouse is used for pointing and gesturing, then maneuverability is improved, but typing function is lost requiring users to switch to a keyboard
Solution Approach 1:
The touch mouse is designed to perform multiple functions: it can detect both gesture operations (swiping, clicking) and simulate keyboard key presses. The touch panel detects finger touches and generates corresponding key output signals to a host, enabling the device to serve as both a pointing input device and a keyboard replacement, thus resolving the contradiction between maneuverability and typing functionality
2Reliability
If distinct keyboard device and touch mouse are used, then each device can perform its specialized function, but user convenience deteriorates due to frequent switching
Solution Approach 1:
The patent combines the keyboard device and touch mouse into a single integrated device. The touch mouse housing includes a touch panel that can detect finger touches and generate keyboard key output signals, merging the functions of both devices into one unit. This eliminates the need for users to switch between separate keyboard and mouse devices, thereby improving user convenience while maintaining device specialization through distinct operation modes

AI summary
A method used in a touch mouse includes: providing a touch area; using the touch area to detect a touch of a user's finger on the touch area to sense and generate a touch signal; and, generating a corresponding key output signal to a host by simulating a condition of pressing at least a key of a keyboard device according to the touch signal.
