Wearable Ring Mouse with Optical Sensing for Keyboard Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mouse devices are large and inconvenient for carrying, requiring frequent hand movement between the mouse and keyboard, which can lead to discomfort and increased risk of Carpal Tunnel Syndrome.
Innovation Solution
A wireless ring mouse device worn on the finger, featuring a compact annular structure with integrated optical and click sensors, pressure sensors, and a circuit system for detecting finger movements and clicks, allowing seamless integration with keyboard use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a regular mouse device is used, then mouse functionality is achieved, but the device size is large and inconvenient for carrying
Solution Approach 1:
The patent segments the traditional mouse device into a wearable ring structure that fits on the finger, separating the mouse functionality from the conventional handheld form factor. The ring structure allows the optical sensor and other components to be distributed around the finger, enabling mouse operations without requiring a large handheld device.
Solution Approach 2:
The patent transitions from a two-dimensional handheld mouse to a three-dimensional wearable ring structure that wraps around the finger. This dimensional change allows the device to be worn on the body rather than held in the hand, significantly reducing the space required for carrying and storage.
2Ease of operation
If a regular mouse device is used, then mouse operations can be performed, but frequent hand movement between mouse and keyboard is required
Solution Approach 1:
The wearable ring mouse allows the user's finger to naturally rest on the keyboard while performing mouse operations, eliminating the need to reach out to a separate mouse device. The finger wearing the ring can simultaneously type and perform mouse clicks, allowing the hand to serve both functions without movement between devices.
3Ease of operation
If a regular mouse device is used, then standard mouse functions are provided, but the risk of developing Carpal Tunnel Syndrome increases
Solution Approach 1:
The wearable ring mouse enables dynamic and flexible finger movements that are more natural and ergonomic compared to the fixed wrist position required by traditional mice. The finger can move independently and naturally while wearing the ring, reducing strain on the wrist and forearm muscles that leads to Carpal Tunnel Syndrome.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient, portable, and ergonomic mouse operation, reducing the risk of Carpal Tunnel Syndrome by allowing simultaneous typing and mouse functions without hand movement, and providing space-saving benefits for laptops.
Implementation Method 1
The sensing module has an optical sensor that emits a sensing light to a reference surface for detecting the movements of the finger relative to the reference surface
