Irradiation Control Device for Continuous Alert Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing alert and guidance systems face challenges in ensuring immediate attention and understanding, particularly for drivers of bicycles or two-wheeled vehicles, and pedestrians, due to non-display times in visible-light animations, which can delay reaction times.
Innovation Solution
An irradiation control device and method that employs a configuration of first and second irradiation elements, where the second element is activated when the first is extinguished, ensuring continuous visibility of the intended message or direction, preventing delays in understanding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If visible-light animation is used to convey alert or guidance information, then the meaning is easily conveyed and visibility is improved, but non-display time causes delay in understanding by the target person
Solution Approach 1:
The patent applies the continuity principle by ensuring that the alert information display has no black screens or non-display periods. The display continuously shows alert information through persistent rendering of graphical elements on the head-mounted display, eliminating gaps in information delivery to the user's field of view.
Solution Approach 2:
The patent implements preliminary action by performing depth adjustment of the display content in advance. The processor adjusts the depth of the graphical alert information based on the distance between the user and the hazard before the user potentially encounters it, ensuring the information is optimally positioned in the augmented reality field of view ahead of time.
2Ease of operation
If animation with blinking, lighting in turn, or sliding is used, then attention is attracted and visibility is improved, but the non-display time delays the understanding of content
Solution Approach 1:
The patent eliminates non-display time by continuously rendering alert graphical elements in the user's field of view. The display maintains persistent visibility of hazard information through continuous graphical representation, ensuring no interruptions in information delivery while still using animation effects for attention attraction.
Solution Approach 2:
The patent uses dynamic graphical elements and animations on the head-mounted display to attract attention. The alert information is displayed with dynamic visual characteristics that move or change appearance to capture the user's attention, while maintaining continuous display to avoid delays in understanding.
3Adaptability or versatility
If visible-light animation has non-display time, then the animation effect is achieved, but the guidance may be overlooked by pedestrians or drivers
Solution Approach 1:
The patent ensures continuous display of alert information to eliminate gaps where guidance might be overlooked. The system continuously renders graphical alert elements in the user's field of view without black screens or non-display periods, maintaining constant visibility to ensure reliable recognition of hazard warnings and guidance information.
Solution Approach 2:
The system performs depth adjustment and positioning of alert information in advance based on the user's distance from hazards. By pre-positioning the graphical alert elements at appropriate depths in the augmented reality field of view, the system ensures the guidance information is reliably visible and cannot be overlooked before the user encounters the actual hazard.

AI summary
An irradiation control device is a device configured to control irradiation of light indicating a predetermined intention to a surrounding person, and includes an irradiation control unit configured to perform control to irradiate a first irradiation element, and a second irradiation element, which is irradiated when the first irradiation element is extinguished, and indicates an intention of the irradiation. As a result, light can be irradiated such that the attention of a target person is easily attracted and a delay in understanding by the target person is easily avoided.
