Remote Driving Display Layout for Peripheral Speed Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote driving systems face challenges in allowing operators to intuitively sense vehicle speed, especially during turns, as liquid crystal displays for Gaussian blobs can be distracting and disrupt the central visual field, leading to a diminished sense of speed.
Innovation Solution
A remote operation device with an image acquiring section and dual display portions, where objects move from the central visual field region to peripheral regions, preventing them from entering the central visual field and maintaining a clear view of surroundings, even during turns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If liquid crystal displays displaying Gaussian blobs are used to show vehicle speed, then the driver can intuitively recognize vehicle speed, but the central visual field may be obstructed when the operator turns the vehicle or shifts sightline
Solution Approach 1:
The patent applies dimensional change by moving the speed indication objects from the central visual field region to the peripheral visual field region (upper or lower sides) of the display. This spatial repositioning in another dimension (peripheral vs central field) allows speed information to be displayed without obstructing the operator's central view of the vehicle surroundings, resolving the contradiction between speed recognition and visual field obstruction.
2Measurement precision
If separate liquid crystal displays for Gaussian blobs are added, then vehicle speed can be displayed, but the device complexity increases
Solution Approach 1:
The patent merges the speed indication function with the existing surround view display by utilizing the same display device. Instead of adding separate liquid crystal displays for Gaussian blobs, the invention combines multiple functions (surround view visualization and speed indication) into a single integrated display system, thereby reducing device complexity while maintaining speed recognition capability.
3Loss of information
If objects are displayed in the central visual field region, then speed information is visible, but the operator's ability to see surroundings deteriorates
Solution Approach 1:
The patent segments the display area into distinct functional regions: the central visual field region is dedicated to displaying the surround view image for situational awareness, while the peripheral visual field regions (upper and lower sides) are allocated for displaying speed indication objects. This spatial segmentation allows both speed information and surroundings visibility to be maintained simultaneously without interference.

AI summary
A remote operation device that drives a vehicle by remote operation exterior to the vehicle, including: an image acquiring section that acquires an image surroundings of the vehicle from the vehicle; a first display portion that displays the image of the surroundings; and second display portions that are provided at peripheral visual field regions, which are other than a central visual field region of the first display portion, at at least one of an upper side or a lower side of the first display portion, and that display objects that move from the central visual field region side toward transverse direction end portions.
