One-Handed Interdigit-Coordinated Mobile Keyboard Input Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current text input technologies for mobile devices require finger repositioning, are not portable, and necessitate visual attention, making them inefficient and inconvenient for users who need to input specific textual content on-the-go.
Innovation Solution
A one-handed ergonomic user input device that detects natural finger movements without requiring finger repositioning, using a chassis designed to capture flexion, extension, adduction, and abduction movements, allowing for multiple keystrokes without lifting fingers off the device, and transmitting character codes wirelessly to electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional keyboards are used, then text input functionality is provided, but finger repositioning is required and visual attention is needed
Solution Approach 1:
The device segments text input into multiple simultaneous finger presses on a single key, eliminating the need for finger repositioning. Each key can be pressed by multiple fingers at different positions, and combinations of presses generate different characters, allowing all fingers to remain on the device throughout input.
Solution Approach 2:
The invention adds temporal and combinatorial dimensions to a single spatial location. Instead of moving fingers across space to different keys, multiple fingers press the same key at different times or in different combinations, creating a multi-dimensional input space that eliminates repositioning while maintaining text input capability.
2Productivity
If QWERTY keyboard is used, then character input is enabled, but training period is required and visual attention is needed
Solution Approach 1:
The device provides tactile feedback through the arrangement and texture of keys that guide finger placement and pressing patterns. The physical design of the key surface with varying textures and heights serves as a self-teaching mechanism, allowing users to learn through tactile exploration rather than memorizing key positions, thereby reducing training requirements.
3Ease of operation
If desk-based keyboards are used, then text input is provided, but portability is lost
Solution Approach 1:
The invention merges multiple keyboard functions into a single portable device that can be held in one hand. By combining the functions of multiple keys into a single physical location that responds to multiple finger presses, the device achieves full text input capability in a compact, portable form factor that weighs minimal amounts and can be easily carried.
4Weight of moving object
If one-handed operation is implemented, then portability is improved, but input complexity increases
Solution Approach 1:
The device design with textured key surfaces and tactile feedback patterns guides the user's fingers into correct positions and pressing patterns automatically. The physical structure of the keys provides natural stopping points and tactile cues that simplify the coordination task, making one-handed operation intuitive despite the sophisticated input capabilities.

AI summary
A single-hand interdigit-coordinated mobile keyboard input device has a chassis configured to conform to human fingers with a plurality of articulating finger frames connected adjacent to each other, a plurality of user input elements, a processing device, and a signal transmitter. The plurality of user input elements is connected around the chassis in order to capture flexion, extension, adduction, and abduction movements of the plurality of articulating finger frames. The processing device interprets signals received from the plurality of articulating finger frames into desired output communication elements such as text characters. The signal transmitter sends the interpreted output to a computing device.
