Exit and Entry Location Indicators for Side View Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles, users may lose sight of objects when they depart from the display range of side view image display devices, leading to inadequate safety conditions due to discrepancies between displayed and actual views.
Innovation Solution
An information-presenting device with an imaging unit, display unit, object-recognition unit, exit location indicator, and entry location indicator is implemented, which captures side views, displays images, recognizes moving objects, and indicates their predicted entry and exit locations to prevent loss of sight during object movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If side view images are displayed on a display device, then users can monitor objects in the side view, but users may lose sight of objects when they depart from the display range
Solution Approach 1:
The system performs preliminary action by displaying exit location indicators before objects actually leave the display range. The object recognition unit detects objects and calculates their trajectories, then the display control unit shows indicators at predicted exit positions in advance, allowing users to maintain awareness of objects before they completely depart from view.
Solution Approach 2:
The patent introduces intermediary elements (exit location indicators and entry location indicators) that mediate between the display device and the user. These indicators serve as intermediate information carriers that bridge the gap when objects move in and out of the display range, helping users maintain continuous awareness without needing to directly see the objects themselves.
2Area of stationary object
If the display range is expanded to cover more area, then users can see more objects, but the display device complexity increases
Solution Approach 1:
The patent applies dimensionality change by adding temporal information to the spatial display. Instead of merely expanding the spatial display range, the system uses the time dimension by showing exit location indicators that predict future positions and entry location indicators that show where objects will appear. This transforms a spatial problem into a spatio-temporal solution.
Solution Approach 2:
The system creates simplified copies or representations of object information through indicators rather than displaying the actual objects themselves. The exit location indicators and entry location indicators are simplified visual cues that convey essential information about object positions and movements without requiring the full complexity of displaying and tracking actual objects across an expanded display range.

AI summary
An information-presenting device includes an imaging unit, a display unit, an object-recognition unit, an exit location indicator unit and an entry location indicator unit. The imaging unit captures an image of a side view from a host vehicle. The display unit displays an image captured by the imaging unit or a image generated based on the captured image. The object-recognition unit recognizes an object lateral to the host vehicle moving relative to the host vehicle. The exit location indicator unit displays an exit location indicator at or near a location where the object is last displayed in the display unit when the object departs from a display range of the display unit. The entry location indicator unit displays an entry location indicator in a window through which an occupant views outside of the vehicle or in a peripheral region of the window. The entry location indicator indicates a location where the object is predicted to appear.
