Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing head-mounted display (HMD) systems do not provide an intuitive method for users to easily scroll through content, regardless of their head orientation.

Innovation Solution

A display control device and method that acquires the orientation of a display unit and a terminal using detecting units, allowing the display control unit to scroll content based on the orientation, enabling intuitive scrolling and selection of content and objects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If content is displayed at fixed HMD regardless of head orientation, then display stability is maintained, but user interaction efficiency deteriorates

Engineering Contradiction:

Improvecontent scrolling easeVSAvoiddisplay control complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The HMD system automatically detects head orientation using sensors and autonomously scrolls content based on detected orientation changes, eliminating the need for manual scrolling operations. The system serves itself by converting orientation detection data into automatic scrolling actions, making content navigation intuitive and effortless.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical scrolling operations with an automated sensor-based orientation detection and control system. Instead of requiring users to physically interact with scrolling mechanisms, the system uses sensors to detect head orientation and automatically adjusts content display accordingly, substituting mechanical user interaction with automated sensor-driven control.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If content scrolling is added based on orientation detection, then user interaction efficiency improves, but device complexity increases

Engineering Contradiction:

Improvecontent navigation speedVSAvoiddetection and control system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The HMD system integrates multiple functions into a unified orientation-based control mechanism. The same orientation detection system serves both for determining content scrolling direction and for overall display control, making the system versatile and efficient without requiring separate dedicated systems for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically changes display parameters (content position, scrolling speed, scrolling direction) based on detected head orientation parameters. By continuously monitoring orientation parameters and adjusting display parameters accordingly, the system achieves fast and intuitive content navigation while maintaining a relatively simple control architecture.

Inventive Principle:

Principle #35Parameter changes
