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 user operations 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, ensuring intuitive and accurate selection through visual or invisible hot areas that adapt to user behavior and device posture.

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:
Improvepointing accuracyVSAvoidoperation accuracy
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The interaction system is segmented into two distinct functional components: a visual indicator element (ray cursor) that provides precise directional feedback, and a target selection mechanism (hot area) that defines the actual interaction zone. This segmentation allows the visual indicator to maintain high precision while the hot area provides operational tolerance, resolving the contradiction between measurement precision and ease of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hot area acts as an intermediary between the user's gaze/pointer and the interactive control. Instead of requiring direct precise alignment between the ray cursor and the control, the hot area serves as a mediator that expands the acceptable interaction zone, making operation easier while maintaining the precision benefits of the ray cursor visual feedback.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If conventional ray cursor interaction is used, then pointing precision is improved, but interaction efficiency deteriorates

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

Solution Approach 1:

By separating the visual indication function (ray cursor) from the interaction detection function (hot area), the system allows users to benefit from precise visual feedback while simultaneously enjoying the efficiency gains from a larger, more forgiving interaction zone. This segmentation eliminates the need for painstakingly precise movements, thereby improving interaction efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hot area extends beyond the minimal necessary interaction zone, providing excessive coverage that accommodates natural variations in user pointing accuracy. This partial expansion of the interaction area allows users to complete interactions more quickly without requiring perfect precision, thus improving overall interaction efficiency.

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If follow-the-head interface is used, then adaptability to user behavior is improved, but compatibility with precise interaction methods deteriorates

Engineering Contradiction:
Improveadaptability to user behaviorVSAvoidoperation accuracy
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The hot area mechanism serves multiple functions: it maintains compatibility with follow-the-head interface dynamics, provides operational tolerance for improved ease of use, and preserves the ability to work with precise visual indicators. This multi-functionality resolves the contradiction by making the system adaptable to user behavior while maintaining operation accuracy.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The hot area can dynamically adjust its properties (such as size, shape, or position) based on user behavior patterns and context, allowing the system to adapt to different user behaviors while maintaining ease of operation. This dynamic adjustment capability enables compatibility with follow-the-head interface while preserving operational accuracy.

Inventive Principle:
Principle #15Dynamics
