Vehicle VR Control for Traffic Event Alerts and User Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of VR devices in vehicles are shielded from vehicle incidents, potentially shocking or surprising them due to disconnection from the vehicle environment, which compromises their immersive experience and safety.
Innovation Solution
A method and vehicle arrangement that utilize a communication link to transfer vehicle data to VR devices, enabling traffic situation-dependent control through control commands that alert users to unpredictable vehicle responses, using wireless technologies like Bluetooth or WLAN, and integrating vehicle sensors to classify events and generate notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the user wears a VR device that shields them from the vehicle environment, then the immersive experience is enhanced, but the user becomes disconnected from significant incidents in the vehicle and may be shocked or surprised
Solution Approach 1:
The patent introduces an intermediary system that mediates between the VR device and the vehicle environment. This system includes a communication link that receives vehicle data (acceleration, braking, collision signals) and a control unit that processes this data to generate control commands. The intermediary translates environmental information into forms suitable for VR display, allowing the user to remain immersed while staying aware of significant vehicle incidents through visual or auditory notifications within the VR interface
Solution Approach 2:
The patent implements a feedback loop where vehicle data is continuously monitored and fed back to the user through the VR device. The control unit receives vehicle data from the communication link, evaluates whether significant incidents are occurring, and sends control commands back to the VR device to display appropriate notifications. This closed-loop feedback system ensures the user remains informed about vehicle events while maintaining immersion
2Reliability
If the VR device displays continuous vehicle incident information, then the user's awareness is improved, but the immersive experience is compromised
Solution Approach 1:
The patent applies local quality by selectively displaying information only in specific contexts. The control unit evaluates vehicle data to determine when significant incidents are occurring and only generates control commands to display notifications during these specific events. During normal driving conditions, the VR device operates without interruptions, maintaining full immersion. The notification display is localized to specific VR interface elements rather than overwhelming the entire display
Solution Approach 2:
The patent uses partial action by providing information selectively rather than continuously. The control unit monitors all vehicle data but only triggers notifications for significant incidents that meet specific criteria. This partial information delivery is sufficient to ensure user safety and awareness while minimizing disruption to the immersive experience during normal operation
Data Source
AI summary
A method of controlling a VR device, in particular VR goggles, of a user in a vehicle interior of a vehicle via a communication link, includes vehicle data being received and evaluated, or receiving evaluated vehicle data via the communication link. At least one traffic event may be classified based on the evaluated vehicle data, to generate control commands for controlling the VR device, by way of which the user of the VR device may be alerted to a response of the vehicle to the traffic event, which may be unpredictable to the user. The examples further relate to a vehicle arrangement.
