Hand Gesture Control for Electronic Appliances via Image Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for electronic appliances, such as television sets, require users to manually operate buttons, which can be inconvenient, especially when the remote controller is not present or when manipulating multiple keys for data broadcasting and EPG functions.
Innovation Solution
An electronic appliance equipped with a video camera, mirror image converter, image adjuster, and controller that adjusts the size and position of the user's image on the display to align with control buttons, allowing for intuitive operation without the need for a physical remote controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a video camera photographs the user's hand to enable remote control operation, then the need for a physical remote controller is eliminated, but the user's hand image does not properly align with the control button position and size on the display
Solution Approach 1:
The system dynamically adjusts the size and position of the user's hand image on the display based on real-time detection of the control button's position and size. The image processing unit resizes and repositions the hand image to match the control button parameters, ensuring proper alignment during operation.
Solution Approach 2:
The system detects the control button's position and size on the display, then uses this information to adjust the hand image accordingly. This feedback loop ensures that the hand image remains properly aligned with the control button, resolving the alignment issue between the photographed hand and the displayed button.
2Measurement precision
If the hand image size is adjusted to match the control button size, then proper alignment is achieved, but the user's position relative to the camera becomes critical
Solution Approach 1:
The system continuously adapts to changes in user position by detecting the control button parameters and adjusting the hand image size and position in real-time. This dynamic adjustment allows users to operate from various positions without requiring precise alignment, as the system compensates for position variations.
Solution Approach 2:
The system changes the parameters of the hand image (size, position, orientation) based on the detected control button parameters and user position. By adjusting these parameters dynamically, the system maintains proper alignment regardless of the user's position relative to the camera.
3Adaptability or versatility
If multiple keys must be pushed for data broadcasting and EPG functions, then comprehensive control is achieved, but the operation becomes troublesome and complex
Solution Approach 1:
The system automatically detects the user's hand gestures and movements to determine which control function is intended, eliminating the need for the user to manually press multiple keys. The hand operation recognition system interprets the user's intentions and executes the appropriate control commands, reducing operational complexity.
Solution Approach 2:
The system replaces the mechanical remote control with a video-based hand gesture recognition system. Instead of requiring physical key presses, the system captures and analyzes hand movements through the video camera, translating gestures into control commands for data broadcasting and EPG functions.

AI summary
An electronic appliance has a video camera for picking up an image of a user of the electronic appliance. The user's image is displayed on a display of the electronic appliance. To adjust the size of the user's image on the display, a measurement zone having a first area is defined on the display. The user holds his or her hand so that the hand is displayed on the measurement zone. A control information determination unit or a CPU generates information indicative of the ratio of the area of the hand in the measurement zone to the area of the measurement zone. According to the generated information, the CPU controls an image adjuster that optimizes the size and position of the user's image on the display.
