AR Display Controller Automatic Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality display devices require user input to switch between operation modes, which is inconvenient and may not adapt well to varying environmental conditions, affecting image quality.
Innovation Solution
A controller that automatically switches between first and second augmented reality operation modes based on environmental parameters such as brightness, number of virtual objects, complexity, size, and distance, without the need for user input, using a sensor and processor to compare these parameters with predefined thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If automatic switching between augmented reality operation modes is implemented, then adaptability to environmental conditions is improved, but device complexity increases
Solution Approach 1:
The display device automatically monitors environmental conditions through sensors and switches between augmented reality operation modes without user input. The controller autonomously determines the optimal mode based on detected parameters such as brightness, motion, or location, enabling the system to serve itself in adapting to environmental changes.
Solution Approach 2:
The controller is designed to handle multiple functions: it manages display content generation, processes sensor inputs, determines optimal operation modes, and controls switching between modes. This multi-functional approach consolidates complexity into a single control unit rather than requiring separate systems for each function.
2Ease of operation
If switching between operation modes is performed automatically, then ease of operation is improved, but reliability may deteriorate due to automated decision-making
Solution Approach 1:
The controller continuously receives feedback from sensors monitoring environmental conditions and adjusts the operation mode accordingly. This closed-loop feedback mechanism ensures that automated switching decisions are based on real-time data, improving reliability by making switching contingent on actual environmental states rather than arbitrary changes.
Solution Approach 2:
The system pre-determines switching criteria and thresholds for different operation modes before actual switching occurs. By establishing predetermined conditions for mode transitions, the system ensures that automated switching follows reliable, pre-planned logic rather than ad-hoc decisions, enhancing consistency and trustworthiness.

AI summary
The present invention relates to a controller for use in a display device. The controller is configured to cause the display device to switch between a first augmented reality operation mode and a second augmented reality operation mode. The controller comprises a sensor adapted to receive an input signal indicative of at least one parameter of an environment captured by a display device sensor of the display device including a field of view of a user, a processor adapted to compare each of the at least one parameter with a corresponding predefined threshold value, and a processor unit adapted to cause the display device to switch between the first and second augmented reality operation modes based on the result of the comparison.
