Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current mobile terminals and head-mounted displays (HMDs) lack effective methods for securely unlocking and managing content, particularly when the device is in a locked state or detached from the user, which can lead to privacy concerns and inconvenience in accessing or re-accessing locked content.

Innovation Solution

A mobile terminal system that uses a head-mounted display (HMD) connected via a mobile terminal, employing sensors to detect specific gestures or eye movements to unlock and manage content, allowing users to view or re-lock content securely based on the device's state and user interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the HMD is locked when detached from the user, then user privacy is protected, but user convenience is reduced when re-accessing content

Engineering Contradiction:

Improveprivacy protectionVSAvoidcontent re-access convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary locking of content when the HMD is detached from the user's head. This preliminary action ensures privacy protection is automatically activated without requiring user intervention, while the system remembers the locked state for seamless re-access upon re-attachment.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If authentication is required every time the HMD is re-attached, then security is maintained, but user experience is degraded

Engineering Contradiction:

ImprovesecurityVSAvoidauthentication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary authentication by detecting the user's head attachment to the HMD. When the HMD senses the user's head position, it automatically authenticates and unlocks content without requiring manual password entry, thereby maintaining security while eliminating authentication time loss.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the HMD automatically unlocks upon re-attachment, then user convenience is improved, but security is compromised

Engineering Contradiction:

Improvere-access convenienceVSAvoidsecurity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary detection of the user's head attachment to the HMD before unlocking content. The detection mechanism verifies biometric characteristics (head shape, position, movement patterns) to authenticate the user, ensuring security is maintained while enabling automatic convenient re-access.

Inventive Principle:

Principle #10Preliminary action

AI summary

Disclosed are a mobile terminal(100) capable of controlling a head mounted display (HMD) and a controlling method thereof. The mobile terminal(100) includes: a sensor(140); a communication unit(110) capable of communicating with a head mounted display(200) configured to display a virtual reality screen; and a controller(180) capable of: controlling the head mounted display(200) to display the virtual reality screen including first content; and when a preset gesture input corresponding to a user's head or pupil movement is detected via the sensor(140) or a sensor(240) of the head mounted display(200), controlling the head mounted display(200) to display locked second content on the virtual reality screen while a worn state of the head mounted display(200) is maintained.
