Head-Mounted Display Interior Overlay for In-Vehicle VR Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of head-mounted display devices in motor vehicles, such as VR or AR glasses, face safety concerns when immersed in virtual reality as they cannot monitor the vehicle's interior, leading to potential unpleasant interactions with unfamiliar drivers or passengers without visual or auditory cues.
Innovation Solution
A method that integrates a control device to overlay images or video feeds of the vehicle's interior onto the display, allowing users to maintain awareness of their surroundings while immersed in virtual reality, triggered by speech detection or approaching destinations, ensuring safety and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If headphones are used for sound output in virtual reality, then immersive audio experience is improved, but user awareness of vehicle interior and driver interactions deteriorates
Solution Approach 1:
The audio output is segmented into two channels: immersive audio through headphones for entertainment content, and ambient audio through speakers for vehicle interior sounds. This segmentation allows simultaneous immersive experience and awareness of surroundings.
Solution Approach 2:
A control device acts as an intermediary between the sensor device and display device, processing sensor signals and coordinating the output of multiple devices to achieve both immersion and awareness.
2Reliability
If head-mounted display device is worn for virtual reality entertainment, then entertainment immersion is improved, but overview of vehicle interior situation deteriorates
Solution Approach 1:
Visual information is segmented into two streams: virtual reality content through the head-mounted display device and real vehicle interior images through the display device. This allows simultaneous immersion and awareness.
Solution Approach 2:
The solution adds a new dimension by overlaying or alternating between virtual reality content and real vehicle interior images, creating a multi-layered visual experience that provides both immersion and situational awareness.
3Ease of operation
If driver touches user on shoulder to get attention, then communication is achieved, but user comfort and safety deteriorates due to unexpected contact
Solution Approach 1:
The system performs preliminary action by displaying vehicle interior images and providing audio feedback before the driver physically contacts the user, allowing the user to anticipate and prepare for the interaction.
Solution Approach 2:
The system provides feedback to the user through the display device and speakers about driver actions and vehicle interior conditions, enabling the user to respond appropriately before physical contact occurs.

AI summary
The invention relates to a method for operating a head-mounted display apparatus (14) in a motor vehicle (10) interior. A control device (12) receives a sensor signal from a sensor device (18), wherein the received sensor signal describes (S1) at least one image of the current interior situation of the motor vehicle (10). The sensor device (18) generates a superimposition signal (S2) which describes a superimposition of the at least one image of the current interior situation (S4) while the predefined output content is being output, and transmits the generated superimposition signal to a display element of the display apparatus (14, S3) and thereby causes the display apparatus (14) to superimpose (S4) the at least one image of the current interior situation while the predefined output content is being output.
