Peripheral Visual Field Attention Device Using Frequency-Dependent Blinking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional attention attracting devices, such as signal lamps, struggle to effectively draw attention when a viewer's line of sight deviates, and their use is limited to situations detectable by sensors, making them less versatile for attracting attention from all directions.
Innovation Solution
An attention attracting device with a light source set to frequencies that appear on in the central visual field and blink in the peripheral visual field, using a combination of on and off states with specific pulse times to enhance visibility and attract attention without the need for sensor-based operations, integrated into mobile bodies like vehicles as headlights or brake lights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a light source is used to present information to a viewer, then information can be transmitted visually, but attention cannot be effectively attracted when the viewer's visual line deviates from the light source
Solution Approach 1:
The light source performs periodic blinking actions at a specific frequency (3-15 Hz) to attract attention in the peripheral visual field. This periodic on-off action creates a visually detectable pattern that draws the viewer's attention even when their visual line is not directly focused on the light source, thereby resolving the contradiction between information transmission and attention attracting capability.
2Reliability
If sensor-based detection is used to trigger attention attracting functions, then attention can be attracted in detected situations, but the use range is limited to predetermined statuses
Solution Approach 1:
The invention extracts the sensor-based triggering mechanism and replaces it with a frequency-based light source operation that functions independently of sensor detection. The light source operates at a specific frequency range (3-15 Hz) that naturally attracts attention in the peripheral visual field, eliminating the need for sensors and expanding the use range to all directions and situations, not just predetermined detected statuses.
3Adaptability or versatility
If a light source blinks at high frequency, then attention can be attracted more effectively, but the light source may appear continuously on in the central visual field
Solution Approach 1:
The invention changes the frequency parameter of the light source to a specific range (3-15 Hz) that creates a perceptual difference between the central and peripheral visual fields. At this frequency, the light appears to blink in the peripheral visual field while appearing continuously on in the central visual field, effectively resolving the contradiction between attention attracting effectiveness and visual field perception accuracy.

AI summary
An attention attracting device that effectively attracts attention and has improved versatility over a conventional technology, a mobile body including this attention attracting device, and a method for controlling the attention attracting device are provided. A predetermined area including a gazing point of a viewer is set as a central visual field at a time of the viewer directing a visual line, and an area other than the central visual field is set as a peripheral visual field. The attention attracting device includes a light source set to such a frequency F [Hz] that the light source is seen to be turned on in a case in which the light source is present in the central visual field and is seen to be blinking in a case in which the light source is present in the peripheral visual field. The mobile body includes the attention attracting device as a lamp body of a vehicle and emits light from the light source to the outside.
