Wearable AR Grip Segmentation for Intuitive Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality (AR) devices lack effective methods for user interaction and control through gesture recognition, particularly in wearable forms, limiting their functionality in controlling connected electronic devices.
Innovation Solution
An AR device identifies a grip position and rotation of an object held by a user using image analysis and sensors, dividing the object into sections for different operations, and provides a virtual guide to facilitate user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If gesture recognition is implemented in wearable AR devices, then user interaction capability is improved, but device complexity increases
Solution Approach 1:
The object is divided into multiple sections along its length, with each section corresponding to a specific grip position. When the user grips a particular section, the AR device performs a predetermined operation. This segmentation approach enables complex interaction capabilities through simple spatial division, avoiding the need for complex gesture recognition algorithms while maintaining versatility in user interaction.
2Measurement precision
If the object is divided into multiple sections for different operations, then control precision is improved, but device complexity increases
Solution Approach 1:
Different sections of the object are assigned different functional qualities, where each section corresponds to a specific operation. The system identifies which section is being gripped and executes the corresponding predetermined operation. This local quality assignment enables precise control differentiation without requiring complex measurement systems, as the distinction is made through simple spatial positioning rather than complex sensing.
3Ease of operation
If a virtual guide is provided to users, then ease of operation is improved, but device complexity increases
Solution Approach 1:
A virtual guide is introduced as an intermediary element that visually indicates which section of the object should be gripped to perform a desired operation. The virtual guide overlays information on the user's field of view, providing intuitive instructions without requiring complex user interfaces or control systems. This mediator approach simplifies operation while theAR device itself maintains relatively simple hardware architecture.

AI summary
A method for operating an augmented reality (AR) device includes identifying a first object from an image of the first object obtained through a camera, identifying a grip position at which a user grips the first object, and performing an operation based on the grip position.
