Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users face annoyance when repeatedly using a mouse or keyboard to scroll through large amounts of web content or digital documents, necessitating a method to operate page content without these input devices.

Innovation Solution

A display method and device that captures a user's facial features to determine their viewing angle and head motion, allowing page content to be scrolled or operated without the need for a mouse or keyboard, using a camera, image-processing, and page-content-scrolling elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users use mouse or keyboard to scroll page content, then page content can be operated, but user operation becomes annoying and tedious

Engineering Contradiction:

Improvepage content operationVSAvoiduser annoyance

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the mechanical input system (mouse and keyboard) with an optical detection system (camera) that captures facial features to determine viewing angle. This substitution eliminates the need for manual mechanical input, thereby reducing user annoyance while maintaining page content operation capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service operation by automatically detecting user viewing angle through camera capture and processing, then autonomously controlling page content scrolling without requiring active user input. The system serves itself by interpreting user gaze to execute operations.

Inventive Principle:

Principle #25Self-service

2Extent of automation

If camera and image-processing elements are added to capture facial features, then automatic page content operation is enabled, but device complexity increases

Engineering Contradiction:

Improveautomatic page content operationVSAvoidsystem structure

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The camera component serves multiple functions: it captures facial features for viewing angle determination, and can potentially capture other user states. This multi-functionality justifies the added complexity by providing automatic operation capability that eliminates the need for separate input devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The image-processing element acts as an intermediary between the camera and the page-content-scrolling element. It processes captured images to extract viewing angle information, which then controls the scrolling operation. This intermediary layer enables automatic operation while managing system complexity through modular design.

Inventive Principle:

Principle #24Intermediary (Mediator)
