Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional headset vision systems either provide a full virtual reality view or a limited augmented reality view, failing to offer a flexible solution that allows users to seamlessly switch between both types of experiences and control the system without physical input.
Innovation Solution
A headset vision system featuring a reconfigurable mirror device and a non-transitory computer-readable storage medium that determines the mirror arrangement, enabling both augmented and virtual reality displays, and allowing user control through inputs received without touch interaction, such as voice or motion commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional virtual reality system covers the entire field of view, then the user experiences complete virtual immersion, but the system cannot provide augmented reality functionality
Solution Approach 1:
The mirror device is made dynamically reconfigurable between different configurations. The mirror can be positioned in a first configuration for augmented reality mode and a second configuration for virtual reality mode, allowing the system to adapt its functionality based on user needs without requiring multiple separate systems.
Solution Approach 2:
The headset vision system is designed to perform multiple functions through a single reconfigurable mirror device. The same optical path and display components are used for both augmented reality and virtual reality modes, eliminating the need for separate systems and reducing overall device complexity while maintaining versatility.
2Area of stationary object
If a traditional augmented reality system provides limited field of view, then the device complexity is reduced, but the system cannot cover the entire field of view
Solution Approach 1:
The mirror device dynamically adjusts its position to change the optical path. In augmented reality mode, the mirror is positioned to allow partial field of view coverage, while in virtual reality mode, the mirror is repositioned to direct the entire display output to the user's eyes, achieving complete field of view coverage when needed.
Solution Approach 2:
The field of view coverage is segmented and controlled by the reconfigurable mirror. The mirror segments the optical path differently depending on the mode: in AR mode, it allows direct viewing of the environment with limited display coverage, while in VR mode, it segments the path to direct all display output to the user, achieving full field of view coverage.
3Ease of operation
If the system requires touch input for control, then the ease of operation is simplified, but the system cannot provide hands-free control capability
Solution Approach 1:
The mechanical touch input system is replaced with an optical eye-tracking system. Cameras detect the user's eye movements and pupil position to determine control inputs, substituting the need for physical touch interaction with a non-contact optical detection method that enables hands-free operation.
Solution Approach 2:
The eye-tracking camera system acts as an intermediary between the user and the system controls. Instead of direct touch interaction, the camera captures eye movement data, processes it to determine user intent, and translates it into system commands, providing a natural hands-free control interface.

AI summary
A headset vision system includes a non-transitory computer-readable storage medium having instructions stored thereon that, upon execution by a processor, cause the processor to determine an arrangement of a mirror device, provide a display on a screen of a display device based on the arrangement of the mirror device, and receive inputs from a user of the headset vision system such that the user is able to control the headset vision system absent the user providing a touch input.
