Object Control Mapping for Intuitive AR Gesture Commands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for controlling objects in augmented or virtual reality environments lack flexibility and user convenience, as they require precise object specification and uniform control methods that do not adapt to the characteristics of various objects, limiting effective control of diverse objects in real-world settings.
Innovation Solution
A method and system that allow users to control objects by specifying a control vector in a real-world coordinate system, mapping it to a control coordinate point in an object reference coordinate system defined by the object's characteristics, enabling intuitive gesture-based control of various objects without the need for precise object specification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional techniques use uniform control methods for all objects, then the control system is simple, but the adaptability to different object characteristics is poor
Solution Approach 1:
The patent applies local quality by defining object-specific reference coordinate systems tailored to each object's characteristics. Each object has its own coordinate system configuration that matches its physical properties and control requirements, allowing the control system to adapt locally to different object types while maintaining a unified overall framework.
Solution Approach 2:
The system changes parameters by dynamically adjusting the reference coordinate system parameters based on the target object's characteristics. When the target object changes, the system reconfigures the coordinate system parameters (origin position, axis directions, scale factors) to match the new object's properties, enabling adaptive control without redesigning the entire system.
2Ease of operation
If conventional techniques require precise object specification, then the control accuracy is high, but the ease of operation deteriorates
Solution Approach 1:
The patent introduces a reference coordinate system as an intermediary between the user's gesture and the object control. The coordinate system acts as a mediator that automatically maps the gesture's spatial information to the target object's control parameters, eliminating the need for users to precisely specify objects while maintaining accurate control through the coordinate transformation process.
Solution Approach 2:
The system replaces the mechanical interaction of precisely pointing and specifying objects with a gesture-based approach. Instead of requiring users to mechanically interact with or precisely indicate object locations, the system captures the gesture's spatial trajectory and uses coordinate system transformation to automatically identify and control the target object.
3Adaptability or versatility
If conventional techniques use predetermined target objects, then the system complexity is low, but the flexibility of control is poor
Solution Approach 1:
The patent implements universality by creating a unified control framework that can handle multiple types of objects with different characteristics through a single gesture-based interface. The reference coordinate system approach provides a universal method that adapts to various object types (lights, appliances, furniture, etc.), allowing one system to serve multiple functions without requiring separate control mechanisms for each object type.

AI summary
According to one aspect of the invention, there is provided a method for assisting object control, comprising the steps of: specifying, in a real-world coordinate system, a control vector corresponding to a gesture or manipulation performed by a user; determining an object indicated by the control vector as a target object to be controlled by the gesture or manipulation performed by the user; performing mapping for specifying a control coordinate point corresponding to a magnitude or direction of the control vector in a target object reference coordinate system defined on the basis of a characteristic of the target object; and determining a control command to be applied to the target object, with reference to the control coordinate point specified by the mapping.
