Solution Overview

Problem

Users of virtual reality (VR) technology face challenges in easily changing the field of view (FOV) to different view angles without physically moving their head or body.

Innovation Solution

A method for controlling a view angle in VR systems, where a host device provides visual content with a specific FOV and detects user gestures to display visual cues and adjust the FOV accordingly based on the detected gestures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the user moves head or body to change field of view, then the view angle changes to see different parts of VR world, but it becomes difficult for user when physical movement is restricted

Engineering Contradiction:

Improveease of changing view angleVSAvoidadaptability to physical movement restrictions

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent replaces the mechanical system of head/body movement with a gesture-based control system. Users perform hand gestures (pinch, swipe, rotate) in the air to control FOV changes, eliminating the need for physical head or body movement while maintaining full view angle adjustment capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces hand gestures as an intermediary between the user's intent to change view angle and the actual FOV adjustment. The gesture recognition system acts as a mediator that translates physical hand movements into virtual camera movements, allowing indirect control of the virtual environment.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If gesture recognition is added to control FOV, then ease of operation improves for users with movement restrictions, but device complexity increases

Engineering Contradiction:

Improveease of changing view angleVSAvoidcomplexity of gesture detection system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent leverages the existing camera and processor of the head-mounted display to perform gesture recognition, making the system multi-functional. The same hardware components used for displaying VR content are also utilized to detect and interpret hand gestures, avoiding the need for separate dedicated gesture sensing hardware.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses its own existing resources (cameras, processors, display) to enable gesture control functionality. The HMD's built-in cameras capture hand movements, the processor analyzes the gestures, and the display provides visual feedback, creating a self-contained gesture recognition system without external dependencies.

Inventive Principle:

Principle #25Self-service

AI summary

The embodiments of the disclosure provide a method for controlling a view angle, a host, and a computer readable storage medium. The method includes: providing a visual content, wherein the visual content has a field of view (FOV) corresponding to a first view angle; in response to determining that a preparation gesture is detected, displaying a visual cue in the visual content, wherein the visual cue indicates a first direction; and in response to determining that the preparation gesture has been changed to a first gesture corresponding to the first direction, adjusting the FOV to correspond to a second view angle based on the first direction.
