Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality technologies limit user interaction capabilities, particularly in selecting multiple objects and adapting interaction modes based on object classification and context, which hinders efficient goal achievement and safety in dynamic environments.
Innovation Solution
The implementation of an augmented reality cursor system that allows for multi-object selection, modal switching based on object classification and context, and enhanced interaction modes, using gestures such as eye movement and voice input to facilitate interaction and maintain selected states across object movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional augmented reality interaction methods are used, then the system is simple to implement, but user interaction capabilities are limited and efficiency is reduced
Solution Approach 1:
The interaction system is segmented into multiple cursor modes (selection cursor, information cursor, manipulation cursor) that can be independently activated based on context. Each cursor mode handles specific interaction tasks, allowing the system to maintain simplicity for basic interactions while providing advanced capabilities when needed.
Solution Approach 2:
The cursor system dynamically switches between different modes based on object classification, user gestures, and environmental context. This dynamic adaptation allows the system to optimize interaction efficiency for each specific situation without requiring a completely complex fixed system.
2Adaptability or versatility
If multiple objects need to be selected and interaction modes adapt based on context, then user capabilities are enhanced, but the system becomes more complex
Solution Approach 1:
The cursor system serves multiple functions through a single unified mechanism. The same cursor can perform selection, information display, and manipulation tasks by switching modes, eliminating the need for separate specialized tools for each function and reducing overall system complexity.
Solution Approach 2:
The system changes cursor parameters (mode, appearance, behavior) based on contextual parameters (object type, user gesture, environmental factors). This parameter-based adaptation allows versatile interaction without requiring fundamentally different systems for each scenario.
3Productivity
If the cursor maintains selected states across object movements, then multi-object selection efficiency is improved, but processing requirements increase
Solution Approach 1:
The system creates lightweight visual copies (markers) of selected objects rather than maintaining complex state information for each object. These markers serve as sufficient representations of the selected state, reducing processing requirements while maintaining selection efficiency.
4Reliability
If context-aware interaction tools are provided, then user safety and efficiency are improved, but system complexity increases
Solution Approach 1:
The system provides continuous contextual feedback to users through the cursor (information about objects, available actions, selected states). This feedback mechanism enhances user awareness and safety without requiring complex additional systems, as the cursor itself serves as the feedback channel.

AI summary
An augmented reality device enables selection and interaction with multiple objects viewed in an augmented reality scene. A cursor is positioned proximate to a first object in response to a first gesture. A selected state of the first object is determined in response to a second gesture. A visual indication of the selected state of the first object is displayed by the augmented reality device. A second position for the cursor, proximate to a second object, is determined. A visual indication of the first object's selected state remains displayed after the cursor is moved to be proximate to the second object.
