Face Recognition View Mode Control for Portable Terminals

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing portable terminals automatically change screen orientation based solely on gravity direction, leading to user inconvenience when the user's eyes are not aligned with the screen orientation, requiring manual settings and adjustments.

Innovation Solution

A method and apparatus that utilize face recognition to detect the user's eye orientation and automatically change the screen view mode to align with the user's gaze, incorporating a camera module to capture images, determine eye orientation, and control the display accordingly, while considering both gravity direction and user orientation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automatic rotation function is turned off to enter horizontal view mode, then user can maintain horizontal view, but user must manually turn on automatic rotation, wait for view change, then turn off again

Engineering Contradiction:

Improveview mode switching convenienceVSAvoidtime for manual rotation adjustment

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs self-service by automatically detecting user eye orientation through camera-based face recognition and autonomously adjusting the view mode to match the user's natural gaze direction, eliminating the need for manual rotation switching by the user

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements feedback by continuously monitoring the user's eye orientation via camera capture and face recognition, then using this information to automatically adjust the display orientation to align with the user's gaze, creating a closed-loop adaptive system

Inventive Principle:

Principle #23Feedback

2Extent of automation

If screen rotation is based only on gravity direction, then automatic rotation function works simply, but user eyes may not align with screen orientation causing inconvenience

Engineering Contradiction:

Improveautomatic rotation capabilityVSAvoiduser viewing comfort

Core Design Contradiction:

Extent of automationVSEase of operation

Solution Approach 1:

The system transitions from one-dimensional gravity-based rotation detection to a two-dimensional approach by incorporating camera-based face recognition to detect eye orientation, adding a new dimension of user-centric orientation detection that complements the gravity sensor data

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The camera module serves multiple functions: it captures images for face recognition to determine eye orientation, and this same captured image data is processed to infer user gaze direction, making the single camera component multi-functional for both automatic rotation and viewing comfort optimization

Inventive Principle:

Principle #6Universality (Multi-functionality)
