VR Headset Displaying Multiple Videos in 3D Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video surveillance systems face limitations in displaying multiple videos simultaneously due to the restricted size of screen walls, which hampers operator efficiency and requires ergonomic compromises, while also consuming energy and generating noise.
Innovation Solution
A virtual reality headset system that allows for the display of multiple videos on a single screen using a virtual reality headset connected to a computer, enabling immersive viewing and interactive control through motion sensors and peripherals, with projection surfaces that can be arranged in various shapes to optimize video arrangement and user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of videos displayed on a video wall is increased, then the probability of detecting incidents improves, but the surface area and footprint of the system increase
Solution Approach 1:
The patent transitions from a two-dimensional video wall to a three-dimensional immersive display using VR headsets. Multiple videos are arranged in a 3D virtual space around the operator, allowing viewing of numerous video feeds simultaneously without increasing physical footprint, as the display occurs in virtual rather than physical space.
Solution Approach 2:
The patent creates virtual copies of video feeds that can be positioned and viewed from multiple angles in a 3D environment. These virtual video instances can be accessed and manipulated without requiring additional physical screens, allowing one physical display device to present multiple virtual video copies simultaneously.
2Productivity
If the video wall is made wider to display more videos, then more videos are visible, but the operator must move to view videos at opposite ends and external devices are located at varying distances
Solution Approach 1:
The patent arranges video feeds in a 360-degree circular or spherical arrangement around the operator's head in virtual space. The operator can view videos in all directions without physically moving, and all interaction devices remain at a consistent distance from the operator's hands, eliminating the ergonomic issues of wide video walls.
Solution Approach 2:
The patent implements dynamic video arrangement where video positions and orientations adjust automatically based on the operator's head movements and selections. Videos can be dynamically repositioned in the 3D space, and the system adapts to operator preferences, providing flexible access to all video feeds without physical movement.
3Productivity
If a video wall is used to display multiple videos, then simultaneous viewing is enabled, but energy consumption increases and noise and heat are generated
Solution Approach 1:
The patent merges multiple video feeds into a single physical display device (VR headset) that presents them in a virtual 3D environment. Instead of requiring multiple physical screens to display multiple videos simultaneously, one energy-efficient display device handles all video rendering in virtual space, significantly reducing power consumption while maintaining simultaneous viewing capability.
4Productivity
If the video wall surface area is increased to view more videos, then more videos can be displayed, but the footprint and cost of the system increase
Solution Approach 1:
The patent eliminates the need for large physical video wall surfaces by rendering multiple videos in a virtual 3D space within a compact VR headset. The system achieves high video display capacity without increasing physical volume, as the display expansion occurs in virtual rather than physical dimensions.

AI summary
This method of displaying images or videos on a mobile display (23) in a first frame, the method comprises: - the real-time acquisition of the position of the display (23) in the first frame, - the calculation of an arrangement of at least two images or videos on at least one projection surface defined in a second frame, and - the display on the display (23) of at least a part of the projection surface seen from an observation point along an observation direction in the second frame, the observation direction being determined in real time as a function of the position of the display (23) measured in the first frame.
