Route Guidance Display Positioning for Short-Distance Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices, such as head-up displays, struggle to effectively guide users through route changes by transitioning guidance display objects when the next guide site is unnecessarily close, leading to reduced attention capture and inappropriate display.
Innovation Solution
The display device adjusts the display position and configuration of guidance objects based on remaining distance and speed, transitioning through a target position offset ahead of the guide site when necessary, and increasing or decreasing the number of display elements to maintain attention and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the guidance display object transitions only to the guide position, then the display is simple and direct, but the user's attention is not sufficiently captured when the remaining distance is short
Solution Approach 1:
The system performs preliminary action by offsetting the target position ahead of the guide position when the remaining distance is short. This allows the guidance display object to transition to a position that anticipates the user's need for attention before the actual guide point is reached, ensuring the user notices the guidance in time to respond appropriately.
Solution Approach 2:
The system dynamically adjusts the transition behavior based on the remaining distance. When the remaining distance is long, the guidance object transitions directly to the guide position. When the remaining distance is short, the system dynamically changes the target position to an offset position ahead of the guide position, making the transition behavior adaptive to the situational context.
2Reliability
If the guidance display object transitions through a longer area, then user attention is better captured, but the positional transition becomes excessive and may confuse the user
Solution Approach 1:
The system changes the parameter of target position based on the remaining distance. By comparing the remaining distance with a threshold value, the system switches between two different target position parameters: the guide position itself when distance is sufficient, and an offset position ahead of the guide position when distance is short. This parameter change ensures appropriate transition length for each situation.
Solution Approach 2:
The system uses feedback from the remaining distance measurement to determine the appropriate transition behavior. The remaining distance serves as feedback that informs whether the guidance object should transition to the guide position directly or to an offset position, creating a closed-loop control system that adapts to the current state.

AI summary
A display device includes: a displayer that displays a guidance display object for guidance along a travel route; an obtainer that obtains, a remaining distance from a current position of the mobile body up to a guide position; and a controller that determines a display position of the guidance display object when it is to be displayed, and causes the displayer to display the guidance display object at the display position determined. The controller: changes the display position to cause the guidance display object to transition from the current position up to the guide position, when the remaining distance is at least a threshold value; and changes the display position to cause the guidance display object to transition from the current position up to a target position offset ahead of the guide position, when the remaining distance is less than the threshold value.
