Solution Overview

Problem

Existing techniques for compensating for motion in electronic devices while in motion are cumbersome and inefficient, often requiring complex user interfaces and multiple key presses, wasting user time and device energy, particularly in battery-operated devices.

Innovation Solution

Implementing methods and interfaces that detect user head movement to dynamically adjust the display content position and state, reducing the need for manual inputs and conserving power.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing motion compensation techniques are used, then motion compensation is achieved, but user interface complexity and operation time increase

Engineering Contradiction:

Improvemotion compensation operationVSAvoidtime for motion compensation

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system automatically detects head movement and triggers motion compensation without requiring user initiation. The head-mounted device self-monitors motion and autonomously activates the compensation process, eliminating the need for manual interface interaction while maintaining effective motion compensation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical interaction (key presses, interface navigation) with automated sensor-based detection. Accelerometers and gyroscopes detect head movement, substituting the mechanical user interface system with an automated sensing and response system that compensates for motion without user involvement.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If existing motion compensation techniques are used, then motion compensation is achieved, but device energy consumption increases

Engineering Contradiction:

Improvemotion compensation reliabilityVSAvoiddevice energy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system uses periodic sampling of accelerometer and gyroscope data at optimized intervals to detect head movement. Rather than continuous processing, the system periodically checks for motion events and triggers compensation only when needed, reducing overall energy consumption while maintaining reliable motion compensation functionality.

Inventive Principle:

Principle #19Periodic action

3Ease of operation

If automated head movement detection is implemented, then operation simplicity improves, but device complexity increases

Engineering Contradiction:

Improveinterface simplicityVSAvoiddetection system complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent leverages existing multi-functional components in head-mounted devices, specifically accelerometers and gyroscopes that serve both navigation/orientation functions and motion compensation detection. By utilizing these existing sensors for dual purposes, the system achieves automated detection without adding dedicated complex hardware, thus improving ease of operation while minimizing increases in device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
