Head Movement Television Control via Camera Motion Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing television accessibility features do not fully cater to the needs of individuals with disabilities, as they often rely on obtrusive eye-tracking technology and limited gesture customization, failing to provide effective control options that are user-friendly and non-disruptive.
Innovation Solution
A system that uses head movements to control television functions, recording and encoding user motions with a camera to assign motion identifiers to specific commands, allowing for customizable and discreet control through gestures such as head movements, without the need for invasive devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If eye tracking infrared devices are used for gesture control, then television control functionality is enabled, but the devices become obtrusive and close to user proximity
Solution Approach 1:
The patent extracts the control functionality from the obtrusive eye-tracking device and relocates it to the television set itself through integrated cameras. This removes the need for separate close-proximity devices while maintaining control capabilities, directly resolving the contradiction between functionality and obtrusiveness.
Solution Approach 2:
The patent introduces head movement detection as an intermediary between user intent and television control. Instead of directly tracking eyes with intrusive devices, the system captures head movements through integrated cameras and translates them into control commands, reducing obtrusiveness while preserving control functionality.
2Ease of operation
If predefined gestures are used for control, then gesture control is implemented, but customization options are minimal
Solution Approach 1:
The patent implements dynamic gesture recognition that adapts to individual users. The system learns and recognizes personalized head movement patterns, allowing each user to define their own gestures rather than being constrained by predefined options. This transforms the static gesture control into a dynamic, customizable system.
Solution Approach 2:
The patent changes the parameters of gesture control from fixed predefined gestures to variable user-defined movements. By capturing and analyzing individual head movement characteristics, the system allows users to customize control gestures according to their preferences and needs, significantly increasing adaptability.
3Measurement precision
If traditional remote control is used, then precise control is achieved, but spatial constraints and physical effort are required
Solution Approach 1:
The patent replaces the mechanical remote control system with an optical detection system. Instead of requiring physical manipulation of a remote device, the system uses integrated cameras to detect head movements and translate them into control signals, eliminating spatial constraints and reducing physical effort while maintaining control precision.
