Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If iris cameras and infrared sources are integrated into the virtual reality device, then authentication security and convenience are improved, but device complexity increases
Solution Approach 1:
The patent combines the iris acquisition function with the virtual reality device by integrating iris cameras and infrared sources into the existing headset structure. The iris camera is positioned to capture iris images through the display screen, while the infrared source illuminates the iris simultaneously, merging authentication functionality with the VR device's existing optical path without requiring separate standalone equipment.
Solution Approach 2:
The display screen and observing lenses of the virtual reality device serve dual purposes: they function as primary display components for VR content while simultaneously acting as optical pathways for iris image acquisition. The observing lenses both focus VR images for the user and transmit iris images to the iris camera, eliminating the need for dedicated authentication hardware and reducing overall device complexity.
2Ease of operation
If the iris camera is positioned to acquire iris images through the display screen, then user convenience is improved, but measurement precision may deteriorate due to potential interference with the display screen and line of sight
Solution Approach 1:
The patent positions the infrared source and iris camera at specific locations on one side of the optical central axis, creating a localized authentication subsystem that does not interfere with the central display area. The infrared source is placed to illuminate the iris through the display screen without blocking the user's view of VR content, while the iris camera is positioned to capture reflected infrared light from the iris through the observing lens without obstructing the primary line of sight.
Solution Approach 2:
The display screen and observing lenses act as intermediary optical elements that transmit both VR display light and iris acquisition light. The observing lens serves as a mediator that focuses both the VR image for the user's eye and the iris image to the iris camera simultaneously, enabling dual functionality without direct interference between the authentication components and the display path.

AI summary
A virtual reality device with iris acquisition function, includes a housing having an accommodating space, an observing lens embedded in the housing, a display screen accommodated in the housing and arranged opposite to the observing lens, and at least one iris camera accommodated in the housing. The virtual reality device further includes at least one infrared source accommodated in the housing, the infrared source is arranged on a focal plane of the observing lens and light emitted from the infrared source passes through the observing lens to an iris of a human eye. The iris camera is configured to acquire an iris image of a human eye through the observing lens and the iris camera is arranged at a position which will not interfere a line of sight of the human eye on the infrared source and the display screen.
