VR Headset Hybrid Interface Tangible Device Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality systems lack effective tools to enhance user interactions beyond natural gestures, limiting immersion and feedback, as existing haptic systems require specific devices and have limited performance in simulating real-world sensations.
Innovation Solution
A virtual reality data-processing device worn on the head that renders a virtual interaction interface superimposed on tangible devices, tracks user interactions, and provides tactile feedback, allowing hybrid interactions that combine virtual and physical elements, enabling enhanced immersion and data display capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If haptic feedback systems are used to provide tactile sensation in virtual reality, then user immersion is improved, but device complexity and requirement for specific equipment increases
Solution Approach 1:
The patent introduces a tangible device as an intermediary between the virtual interaction interface and the user. This tangible device provides tactile feedback without requiring complex haptic mechanisms in the VR headset itself. The tangible device acts as a mediator that translates virtual interactions into physical sensations, resolving the contradiction by externalizing the haptic feedback function to a simpler, separate component.
Solution Approach 2:
The patent creates a tangible copy or representation of the virtual interaction interface on a physical device. This copy provides tactile feedback that mirrors the virtual interactions, allowing users to feel physical sensations corresponding to virtual actions without requiring the VR system itself to generate complex haptic effects. The tangible device serves as a simplified physical counterpart to the virtual interface.
2Productivity
If virtual interaction interface is displayed on small physical device screen, then portability is maintained, but data display capability is limited
Solution Approach 1:
The patent projects the virtual interaction interface from the two-dimensional physical device screen into the three-dimensional virtual space. This projection allows the interface to be displayed at a much larger effective area in the user's field of view while the physical device remains small and portable. The virtual projection exploits the third dimension (depth) to overcome the display surface limitation of the physical device.
Solution Approach 2:
The patent merges the physical device's display capabilities with the virtual reality system's projection capabilities. The physical device provides a compact form factor and basic display function, while the VR system adds a large virtual projection layer. This combination allows the system to achieve both portability (from the small physical device) and large data display capability (from the virtual projection).

AI summary
A virtual reality data-processing device, intended to be worn on the head of a user is disclosed. The device renders, in a field of view of the data-processing device, a virtual interaction interface, at least one part of the virtual interaction interface being rendered superimposed on a tangible device, when the tangible device is located in the field of view of the data-processing device, track at least one body part of the user likely to interact via the virtual interaction interface, detect at least one user interaction on a virtual element of the virtual interaction interface, when the at least one body part of the user is close to or in contact with the tangible device. The development also relates to a system and a method for processing virtual reality data.
