Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional VR tactile feedback using linear motors is used, then human-computer interaction is achieved, but user-to-user interaction sense is lacking
Solution Approach 1:
The patent segments the tactile feedback system into multiple independent actuating elements (first actuating element and second actuating element) that can be independently controlled to provide different tactile sensations corresponding to different interaction types, enabling both human-computer and user-to-user interaction scenarios
Solution Approach 2:
The patent changes the tactile feedback parameters by adjusting vibration frequency, amplitude, and pattern based on the type of interaction detected, transforming the single-mode linear motor feedback into multi-mode tactile feedback that adapts to different interaction contexts
2Adaptability or versatility
If single-mode vibration feedback is used, then device simplicity is maintained, but tactile feedback diversity is limited
Solution Approach 1:
The patent makes the VR handle universally applicable to multiple interaction scenarios by equipping it with both a first actuating element for human-computer interaction and a second actuating element for user-to-user interaction, allowing one device to perform multiple tactile feedback functions
Solution Approach 2:
The patent merges multiple tactile feedback capabilities into a single integrated VR handle system, combining different actuating elements and control mechanisms into one unified device that provides diverse tactile feedback without requiring separate devices for different interaction types

AI summary
In a method for virtual reality (VR) interaction, a plurality of virtual objects in a VR environment is displayed. The plurality of virtual objects includes at least a first virtual object controlled by a first user and a second virtual object controlled by a second user. In response to an interaction initiated by the first virtual object towards the second virtual object, haptic feedback is triggered through a VR device worn by the second user. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.
