VR Controller Tactile Feedback Region Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional VR systems provide tactile feedback to the entire VR interactive controller, resulting in high energy consumption, as they fail to simulate the precise tactile sensations of interacting with virtual objects, leading to an incomplete immersive experience.
Innovation Solution
A method and apparatus that determine the specific region of contact between the user and the VR interactive controller, generating targeted tactile feedback based on the simulated object's properties, reducing the need for widespread tactile feedback and thus lowering energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tactile feedback is provided on the entire VR interactive controller, then the user experiences comprehensive tactile feedback, but energy consumption increases
Solution Approach 1:
The patent segments the tactile feedback system by dividing the controller surface into multiple independent feedback regions. Each region can be independently activated based on contact detection, allowing selective activation of only the regions where the user is actually touching the controller rather than activating the entire controller surface.
Solution Approach 2:
The patent implements local quality by providing different tactile feedback characteristics to different regions of the controller based on local contact conditions. The system detects contact at specific locations and activates feedback mechanisms only in those local regions, matching the tactile feedback properties to the specific interaction point rather than applying uniform feedback across the entire controller.
2Reliability
If tactile feedback is provided on the entire VR interactive controller, then comprehensive tactile coverage is achieved, but the system complexity increases
Solution Approach 1:
The controller is divided into multiple independent feedback regions with individual contact sensors and actuators. This segmentation allows the system to manage complexity by treating each region as an independent unit that can be controlled separately, reducing the overall system complexity compared to a unified feedback system covering the entire controller.
Solution Approach 2:
Each feedback region operates autonomously by detecting contact locally and generating feedback independently without requiring centralized control for each region. This self-service capability reduces system complexity by eliminating the need for complex coordination mechanisms across the entire controller surface.

AI summary
The present application provides a tactile feedback apparatus, comprising: a contact determining module, configured to determine, on a virtual reality (VR) interactive controller, a region where contact between a user and the VR interactive controller occurs; and a tactile feedback module, configured to generate, according to relevant information of an object simulated by the VR interactive controller, at least a first contact feedback in the region where the contact occurs. The present application also provides a VR interactive system. The technical solutions provided by embodiments of the present application are used to cause that it is unnecessary to provide a tactile feedback to a user on the entire VR interactive controller, thereby greatly reducing energy consumption needed for generating a tactile feedback.
