Motion-Based Input System for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic devices burden users with bulky physical or virtual keyboards, which interfere with the visual experience and efficiency of data input, particularly for alphanumerical or character information.
Innovation Solution
An electronic device with a touch-sensitive interface that tracks the movement of a user's finger or stylus to input data by scrolling through options displayed as a scroll wheel, allowing efficient data entry without the need for physical keyboards, and combining this with speech recognition to enhance accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a physical or virtual keyboard is used for data input, then data input functionality is achieved, but the user interface becomes bulky and visual enjoyment is interfered with
Solution Approach 1:
The patent removes the traditional keyboard component entirely from the user interface. Instead of using physical or virtual keyboards, the system extracts the data input function and implements it through motion tracking of a pointing device, eliminating the visual clutter and bulkiness associated with keyboards while maintaining data input capability
Solution Approach 2:
The patent replaces the mechanical keyboard system with a motion-based input system. The controller tracks the movement of a pointing device (mouse, touchpad, or other motion-sensitive device) and translates these movements into data input actions, substituting the mechanical key-press system with a motion-tracking system that requires no physical keyboard
2Ease of operation
If a virtual touch screen keyboard is used, then data input is enabled, but the display screen is occupied and visual experience is reduced
Solution Approach 1:
The patent removes the virtual keyboard overlay from the display screen. Instead of displaying virtual keys that occupy screen real estate, the system extracts the input function and implements it through invisible motion tracking, allowing the full display screen to remain available for visual content while maintaining data input capability
Solution Approach 2:
The patent introduces motion tracking technology as an intermediary between the user and the data input system. The controller monitors the movement of a pointing device and uses this motion data to control data input without requiring visual display of keyboard elements, thus mediating between user input needs and screen space availability
3Productivity
If traditional keyboard input is used, then data entry is possible, but input efficiency and accuracy are limited
Solution Approach 1:
The patent implements a feedback mechanism where the controller continuously monitors the movement of the pointing device and provides real-time control adjustments. The system tracks motion patterns, velocity, and direction to dynamically control data input, providing feedback loops that improve both the speed and accuracy of data entry compared to static keyboard input
Solution Approach 2:
The patent introduces dynamic motion tracking to replace static keyboard input. The system captures the dynamic characteristics of pointing device movement (speed, direction, acceleration) and translates these dynamic parameters into data input control, enabling more efficient and accurate input by leveraging the natural dynamics of human motion rather than discrete key presses
Data Source
AI summary
A method for efficient data input may include displaying a user interface, detecting a plurality of positions of an object, and, controlling a display screen to display a data content, in response to a plurality of movements of the object. If the controller determines the object moved substantially in a first direction, the display screen modifies the data content based on a group of data choices. If the controller determines the object moved substantially in a second direction, the controller stores, into a memory, the data content currently being displayed on the display screen.
