Solution Overview
Problem
Existing methods for interacting with augmented and virtual reality environments are cumbersome, inefficient, and create a significant cognitive burden on users, often requiring multiple inputs and providing insufficient feedback, leading to errors and energy wastage, particularly in battery-operated devices.
Innovation Solution

Engineering Contradiction Analysis
1Productivity
If conventional input methods are used for interacting with virtual reality environments, then basic interaction functionality is achieved, but user efficiency deteriorates and cognitive burden increases
Solution Approach 1:
The system provides real-time visual feedback by displaying indicators at the boundary between virtual and physical spaces, showing users exactly where their inputs are being registered and what actions are available. This feedback loop reduces cognitive burden by making the interaction model transparent and intuitive, allowing users to understand system state without mental overhead.
Solution Approach 2:
The patent introduces an intermediary indicator element that mediates between the user's physical input and the virtual environment response. This indicator serves as a visual bridge, showing the connection between physical space interactions and virtual object manipulation, thereby simplifying the interaction model and improving user efficiency.
2Reliability
If multiple inputs are required to achieve desired outcomes, then precise control is achieved, but interaction time increases and energy consumption increases
Solution Approach 1:
The system performs preliminary actions by automatically detecting when a user intends to interact with a virtual object through physical space gestures, and pre-positioning the interaction state before explicit confirmation is needed. This reduces interaction time while maintaining control precision through the visual indicator that confirms system readiness.
Solution Approach 2:
The interaction system serves itself by automatically interpreting physical gestures and mapping them to appropriate virtual actions without requiring multiple explicit user commands. The visual indicator provides self-confirmation to the user, eliminating the need for redundant inputs and reducing overall interaction time.
3Reliability
If multiple inputs are required for virtual object manipulation, then accurate operation is achieved, but energy consumption increases in battery-operated devices
Solution Approach 1:
The system reduces energy consumption by implementing self-service interaction where a single physical gesture is automatically interpreted and executed as a complete interaction sequence. The visual indicator provides self-confirmation, eliminating the need for multiple input commands that would otherwise be required to ensure accurate operation, thereby reducing overall energy usage in battery-operated devices.
4Reliability
If conventional feedback mechanisms are used, then basic system response is achieved, but user understanding of input-output connection deteriorates
Solution Approach 1:
The patent enhances feedback by providing visual indicators at the boundary between physical and virtual spaces that show users exactly where their inputs are registered and what virtual actions are available. This maintains reliable system response while preventing information loss about the connection between user inputs and system responses, making the interaction model transparent and understandable.
