Adaptive Viewpoint Timing for 3D Navigation Intent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation methods in 3D spaces require active user interaction, which is not suitable for lean-back scenarios like watching 3D content, often resulting in unwanted activation of navigation points when users simply view them without intending to navigate.
Innovation Solution
A method that detects the current viewpoint rotation angle and determines its agreement with navigation points, using a timing mechanism with adaptive delay and duration based on the degree of agreement and a viewpoint rotation model, to accurately predict user intent and prevent unintended navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a timing mechanism is used to activate navigation points after a fixed delay, then navigation can be initiated, but unwanted activations occur when users simply view content without intent to navigate
Solution Approach 1:
The patent applies dynamics by making the timing mechanism adaptive rather than fixed. The delay and activation period parameters are dynamically adjusted based on the degree of agreement between the current viewpoint rotation angle and the navigation point direction, allowing the system to respond differently to intentional vs. incidental viewing
Solution Approach 2:
The patent changes parameters by modifying the delay and activation period values based on the agreement degree. When agreement is high (intentional viewing), the delay is reduced or activation enabled; when agreement is low (incidental viewing), the delay is increased or activation prevented, thus resolving the contradiction between enabling navigation and preventing unwanted activations
2Speed
If the timing mechanism delay is reduced for faster navigation response, then navigation speed improves, but false activations increase when users accidentally look at navigation points
Solution Approach 1:
The patent dynamically changes the delay parameter based on the degree of agreement between viewpoint rotation and navigation point direction. High agreement triggers shorter delays for fast response, while low agreement maintains longer delays to prevent false activations, thus resolving the speed-reliability contradiction
3Reliability
If the timing mechanism activation period is extended to ensure user intent, then false activations are prevented, but navigation responsiveness decreases
Solution Approach 1:
The patent dynamically adjusts the activation period parameter based on the degree of agreement. When agreement is high, the activation period is shortened for quick execution; when agreement is low, the period is extended to ensure intent verification, thus resolving the reliability-time loss contradiction
