Solution Overview

Problem

Conventional high-precision ray cursor interaction methods are incompatible with follow-the-head interfaces in extended reality (XR) environments, leading to inaccurate operation and low interaction efficiency.

Innovation Solution

Implementing interactive controls with corresponding control hot areas that allow for fault-tolerant interaction by enlarging the detection area beyond the control itself, using visual or invisible hot areas, and employing multimodal input methods to accurately determine user intentions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional high-precision ray cursor interaction method is used, then measurement precision is improved, but ease of operation deteriorates and compatibility with follow-the-head interface is lost

Engineering Contradiction:
Improveinteraction accuracyVSAvoidoperation difficulty
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The interaction system is segmented into multiple independent interactive controls, each with its own detection area. This allows the system to process selections from multiple controls simultaneously, improving both precision and ease of operation by distributing the interaction burden across separate, manageable elements rather than requiring precise single-point targeting

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from traditional 2D screen-space ray cursor interaction to 3D spatial interaction with volumetric detection areas. By adding the third dimension (depth/spatial extent) to the detection area, the system accommodates head-following interfaces while maintaining selection precision through multi-dimensional spatial relationships

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Measurement precision

If conventional ray cursor interaction is used, then precision is improved, but productivity deteriorates due to low interaction efficiency

Engineering Contradiction:
Improveselection precisionVSAvoidinteraction efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The system performs preliminary detection by continuously monitoring selection information across multiple interactive controls before final confirmation is needed. This preliminary action allows the system to pre-process and prepare interaction states, reducing the time required for final interaction execution and improving overall efficiency

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms that provide users with information about their current selection state across multiple controls. This feedback enables users to make faster, more informed decisions about which control to activate, improving interaction efficiency while maintaining precision through confirmed selections

Inventive Principle:
Principle #23Feedback
