Optical Remote Pointer Control via Imaging Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controllers with free cursor functions require acceleration and gyro sensors, increasing production costs and power consumption, and user customization is complicated through methods like numbered buttons, ID/password input, or biometric authentication.
Innovation Solution
An image display apparatus with an imaging unit, detecting unit, and control unit that captures images of the remote controller and user's face to detect the light emitting unit and movement, allowing for customizable button display and pointer control based on user recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If acceleration sensor and gyro sensor are built in remote controller to provide free cursor function, then free cursor function is achieved, but production costs and power consumption increase
Solution Approach 1:
The patent replaces the mechanical sensor-based detection system (acceleration sensor and gyro sensor) with an optical detection system using an imaging unit (camera) to capture images of the remote controller. The imaging unit detects the position and movement of the remote controller through image processing, eliminating the need for complex mechanical sensors and reducing production costs while maintaining the free cursor function.
2Adaptability or versatility
If numbered buttons or ID/password input method is used for user customization, then user identification is achieved, but operation complexity increases
Solution Approach 1:
The patent implements self-service user identification by using the imaging unit to automatically capture images of the user's face or the remote controller. The system automatically identifies the user and customizes the button display without requiring manual input of IDs, passwords, or selection of numbered buttons. This eliminates complex authentication operations while enabling user-specific customization.
Solution Approach 2:
The system performs preliminary user identification by capturing images before the user needs to operate the remote controller. The imaging unit continuously monitors and identifies the user in advance, so that when the user operates the remote controller, the personalized button display is already prepared and displayed, eliminating the need for on-demand authentication.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables cost-effective addition of functions to remote controllers by using image capture and recognition to control pointer movement and button display, simplifying user interaction without the need for complex sensors or authentication methods.
Implementation Method 1
an imaging unit for capturing an image in a direction in which the image display unit is displaying the still image or the moving image
Implementation Method 2
a detecting unit for detecting a light emitting unit of a remote controlling device included in the image captured by the imaging unit
