Spatial Gesture Remote Control for TV Function Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote controls for image apparatuses, such as TVs, become cumbersome due to the increasing number of keys required for multi-functionality, making it inconvenient for users to input commands without physical key manipulation.
Innovation Solution
A method and system that allow user commands to be executed through spatial movement of a user input device, such as a remote control, where the direction and distance of movement determine the function to be performed, eliminating the need for key manipulation, and enabling functions like channel changes, volume control, and mode selection through directional gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of keys on the remote control is increased to provide more functions, then the functionality of the remote control is improved, but the size and complexity of the remote control increases
Solution Approach 1:
A single key on the remote control is designed to perform multiple functions through combination operations. When two keys are pressed simultaneously, they execute a first function; when three keys are pressed simultaneously, they execute a second function. This allows one physical key to provide multiple functionalities, reducing the need for additional keys while maintaining versatility.
Solution Approach 2:
Multiple key press operations are merged into a single functional unit. The remote control combines the pressing actions of multiple keys into one coordinated input mechanism, where the combination of key presses triggers different functions. This merging approach allows complex operations to be executed through unified input patterns rather than requiring separate dedicated keys for each function.

3Productivity
If a user presses a key for a long time to execute a reiteratively operable function, then the function execution speed is improved, but the ease of operation deteriorates
Solution Approach 1:
The remote control dynamically changes its response based on the duration of key pressing. When a key is pressed for a short duration, it executes a first function; when the same key is pressed for a longer duration, it executes a second function. This dynamic response allows the system to adapt to different user intentions based on press duration, providing both quick single-actions and accelerated repetitive operations without requiring excessive holding time.
Solution Approach 2:
The system changes the operational parameter of key press duration to differentiate between functions. By monitoring how long a key is held down, the remote control transitions between different operational modes. This parameter-based differentiation allows the same physical key to trigger different functions based on temporal characteristics, improving both execution speed and ease of operation.
