VR Display Event Notification in Peripheral Sectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual reality systems, events occurring outside the user's viewing area are not effectively notified, requiring the user to turn their head away from the primary view to observe these events, which can be less interesting or important.
Innovation Solution
A method that identifies a current viewed sector and determines a sub-portion of it to display content indicative of events happening in non-viewed sectors, using manual selection, predefined rules, image attributes, or trained models like convolutional neural networks to automatically detect and overlay notifications within the user's field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the user turns their head to view events in non-viewed sectors, then they can observe events outside the primary view, but they lose focus on the currently viewed content and experience disruption
Solution Approach 1:
The patent introduces an intermediary notification element that mediates between the event in the non-viewed sector and the user's current view. Instead of requiring direct viewing of the event, the system displays a notification containing event information within the current viewing area, allowing users to remain focused on their primary content while still accessing information about peripheral events.
Solution Approach 2:
The patent adds a new dimensional layer to the VR display by overlaying notification elements within the existing three-dimensional virtual space. These notifications appear as additional visual information layers that coexist with the primary viewed content, enabling event information presentation without requiring spatial repositioning or head movement.
2Loss of information
If the system displays notifications in the viewed sector, then events in non-viewed sectors are notified without head movement, but the notification may obstruct important content in the viewed sector
Solution Approach 1:
The patent applies local quality by making the notification display adaptive to the local characteristics of the viewed sector. The system analyzes the visual content and identifies regions with lower information density or importance, then places notifications in those specific local areas. This ensures that notifications are displayed in locations least likely to obstruct important content, preserving the quality of the primary viewing experience.
Solution Approach 2:
The notification placement is dynamic rather than static. The system continuously monitors the viewed sector for changes in content importance and adjusts notification positions accordingly. If important content appears in an area previously designated for notifications, the system relocates the notification to maintain optimal viewing experience while still delivering event information.
Data Source
AI summary
A method comprises providing video data representing at least part of virtual space to a user for viewing, identifying a current viewed sector of the virtual space based on user position, determining a sub-portion of said viewing sector, identifying an event occurring in a non-viewed sector of the virtual space, and displaying content indicative of the event in the sub-portion of said current viewing sector. The displaying step may comprise displaying a graphical notification of the event in the sub-portion, or in alternative embodiments, displaying video data showing the event in the sub-portion.
