Dynamic Marker Animation for Driver Confidence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle systems fail to provide occupants with a sense of safety and attention when the vehicle is in automatic drive mode, leading to potential distraction and unease due to monotonous display of preceding markers, which do not change with varying safety levels.
Innovation Solution
An in-vehicle device with a display unit that shows animated markers with varying colors, shapes, and positions to indicate normal, alert, or failure states, reducing driver distraction by providing visual cues about the vehicle's status and direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display position and size of the preceding marker remain unchanged while the forward direction safety level is not changed, then the system maintains stable information display, but the occupant feels uneasy and cannot confirm that vehicle automatic drive is being operated normally
Solution Approach 1:
The patent applies the Dynamics principle by transforming the static preceding marker into a dynamic animated marker that periodically changes its display position around the vehicle-corresponding position. This animation provides visual feedback that the automatic drive system is actively operating, thereby improving occupant confidence without requiring complex additional hardware or system changes.
Solution Approach 2:
The patent implements Periodic action through the animated marker's periodic movement around the vehicle-corresponding position. This rhythmic visual pattern creates a recognizable signal for the occupant that the system is functioning normally, addressing the unease caused by static displays while maintaining simple system architecture.
2Ease of operation
If the display position and size of the preceding marker remain unchanged while the forward direction safety level is not changed, then the system maintains simple display control, but the monotonous display leads to the possibility that the occupant pays less attention to the vehicle automatic drive
Solution Approach 1:
The patent uses the Dynamics principle to create an animated marker that moves periodically around the vehicle-corresponding position. This dynamic visual element captures and maintains occupant attention more effectively than a static marker, improving ease of operation in terms of driver engagement without adding significant complexity to the display control mechanism.
3Reliability
If an animated marker with varying position is displayed to indicate normal operation, then the occupant gains a sense of safety and visual confirmation of system operation, but the display complexity increases
Solution Approach 1:
The patent applies Periodic action by implementing a marker that periodically changes its position around the vehicle-corresponding position. This periodic animation provides clear visual confirmation of system operation and enhances perceived reliability, while the regular pattern keeps the control logic relatively simple and predictable.

AI summary
An in-vehicle device includes: a drive assist unit configured to perform drive assist processing; a display unit configured to display an image in a display area with the image overlapped on a scene in a real space ahead of a vehicle; and a display control unit configured to control the display unit to display, in a normal state while the drive assist processing is performed, an image of a first marker (306) at a vehicle-corresponding position as a position in the display area corresponding to a position where the vehicle is estimated to be positioned in the real space in a predetermined time. The first marker (306) has a first color, the first marker (306) has a first shape that has a smooth outline and fluctuates, and a display position of the first marker (306) varies periodically from the vehicle-corresponding position.
