Virtual Object Interaction Scripts for Haptic Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Game developers face the challenge of managing interactions between wearable or non-wearable haptic devices and virtual worlds within game engines, as existing engines lack direct support for such devices, requiring substantial coding to handle device interactions and haptic feedback.
Innovation Solution
The implementation of virtual object interaction scripts that receive collider data from game engines to manage interactions between virtual characters and objects, allowing for complex interactions like picking up or dropping objects, and providing haptic feedback without additional coding, by determining object interactivity and controlling haptic responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If game developers manually code interactions between haptic devices and virtual worlds, then haptic feedback functionality is achieved, but development complexity and time consumption increase significantly
Solution Approach 1:
The patent introduces an interaction script as an intermediary layer between the game engine and haptic devices. This script automatically manages device interactions, collision detection, and haptic feedback generation, eliminating the need for developers to write complex custom code while maintaining full haptic functionality.
Solution Approach 2:
The interaction script enables the system to automatically handle haptic device integration without requiring manual coding by developers. The script self-manages collision detection, interaction determination, and feedback generation, making the system self-sufficient for haptic device support.
2Measurement precision
If comprehensive collision detection and interaction management are implemented, then interaction accuracy improves, but computational overhead increases
Solution Approach 1:
The interaction script implements selective collision detection by determining whether virtual objects are interactable before performing full interaction analysis. This partial action approach maintains high detection accuracy for relevant objects while reducing unnecessary computational overhead for non-interactable objects.
3Ease of manufacture
If a software layer is added to manage device interactions, then ease of development improves, but system architecture complexity increases
Solution Approach 1:
The interaction script serves multiple functions simultaneously: it manages collision detection, determines object interactability, controls virtual hand interactions, and generates haptic feedback commands. This multi-functionality consolidates what would otherwise require multiple separate software components into a single versatile module.
Data Source
AI summary
A method includes receiving first data from a game engine, the first data associated with a virtual interaction between a virtual hand and a virtual object in a virtual world, determining if the virtual object is interactable based on the first data, determining if the virtual hand is touching the virtual object in the virtual world based on the first data, and when it is determined that the virtual object is interactable and the virtual hand is touching the virtual object, outputting second data describing a relationship between the virtual hand and the virtual object based on the first data.
