Dual-Sided AR Display for Brain-Computer Intent Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brain-controlled interfaces and augmented reality devices primarily allow users to express their thoughts or intents only to themselves, lacking effective bi-directional communication with observers.
Innovation Solution
A user interface device with a dual-sided display that projects user intents on one side and corresponding content on the other, utilizing sensors, processing units, and databases to translate and display user thoughts or intents in real-time, enabling simultaneous communication with both the user and an observer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-sided display is used in augmented reality devices, then the device complexity is reduced, but the communication capability between user and observer is limited
Solution Approach 1:
The display is segmented into two distinct sides: a first side displaying content for the user and a second side displaying content for the observer. This segmentation allows the device to serve multiple communication functions simultaneously while maintaining a relatively simple overall structure.
Solution Approach 2:
The display structure transitions from a single-sided (one-dimensional) configuration to a dual-sided (two-dimensional) configuration, enabling content to be presented in different spatial orientations for different users without significantly increasing device complexity.
2Adaptability or versatility
If user intent is displayed only to the user, then the processing requirements are reduced, but the expression capability to observers is insufficient
Solution Approach 1:
The processing system is segmented into separate processing paths: first processing circuitry handles user-side content while second processing circuitry handles observer-side content. This segmentation distributes processing requirements rather than concentrating them in a single complex processor.
Solution Approach 2:
The processing system is designed with multi-functionality to handle different types of content (text, images, videos) and different display requirements for both user and observer simultaneously, making it adaptable to various communication scenarios.
3Adaptability or versatility
If asymmetric content is displayed on both sides of the interface, then the communication effectiveness is improved, but the manufacturing complexity increases
Solution Approach 1:
Different display regions (first side and second side) are assigned different qualities and functions: the first side displays user-specific content while the second side displays observer-specific content. This local differentiation enables effective asymmetric communication while using standard manufacturing techniques for each region.

AI summary
A method and system of a user interface device with dual-sided display which may include a system using a brain computer interface with an Augmented Reality (AR) headset. The user's intent is sent to the system, which processes, analyzes and maps the user's intent. An output corresponding to the user's intent is projected using the user interface device. This output is displayed on the user's side of the display. An image corresponding to the output is displayed on the observer's side of the display.
