Display Control via Eye Blink Frequency Detection

Solution Overview

Problem

Conventional LCD televisions lack intelligence to automatically adjust settings such as volume and brightness based on user engagement, leading to a suboptimal user experience due to low levels of automation in response to user presence and activity.

Innovation Solution

A display controlling method and device that uses an image sensor to detect user presence and calculate eye blink frequency, allowing for intelligent control of the display by executing predetermined operations based on pre-defined rules related to the eye blink frequency, such as adjusting volume, brightness, or channel switching.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If conventional televisions are used without image sensors and eye blink detection, then the device complexity is low, but the extent of automation is insufficient

Engineering Contradiction:

Improveautomatic display controlVSAvoidsystem structure

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The television system automatically detects user presence and eye blink frequency through the image sensor, and autonomously adjusts display parameters (brightness, contrast, volume) without requiring manual user input. The system serves itself by using captured images to calculate eye blink frequency and execute predetermined operations based on the calculated frequency, enabling automatic adaptation to user state.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical control (physical buttons, remote control operations) with an automated optical detection system. The image sensor captures images of the user's eyes, and the processing module automatically calculates eye blink frequency and translates it into display control operations, substituting the mechanical interaction system with an optical-electrical automatic control system.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If manual control of display settings is used, then the device complexity is low, but the ease of operation is reduced when automatic adjustment is needed

Engineering Contradiction:

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The image sensor serves multiple functions: it detects user presence, captures eye images for blink frequency calculation, and provides the basis for automatic display parameter adjustment. By making the image sensor a multi-functional component that handles both user detection and eye behavior analysis, the system achieves intelligent control without proportionally increasing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent replaces manual mechanical control (physical buttons, remote control operations) with an automated optical detection system. The image sensor captures images of the user's eyes, and the processing module automatically calculates eye blink frequency and translates it into display control operations, substituting the mechanical interaction system with an optical-electrical automatic control system.
