Head-Mounted Display for Drone Operator Visual Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of unmanned aircraft face difficulties in distinguishing their own aircraft from multiple aircraft within their visual field, leading to potential collisions or loss of control, especially when aircraft are moving at high speeds.
Innovation Solution
A head-mounted display device that superimposes virtual images onto the user's visual field, providing support information such as markers, moving directions, and indication images to help identify and control the user's own aircraft, while also displaying information about other aircraft in the vicinity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the pilot views multiple unmanned aircrafts in the visual field to monitor and control them, then the pilot can acquire information about the aircrafts, but the pilot loses sight of the own aircraft and cannot distinguish which aircraft is the own aircraft
Solution Approach 1:
The patent applies color changes by displaying the own aircraft with a distinct marker image that has a different color or visual characteristic from other aircraft. This allows the pilot to quickly identify the own aircraft among multiple aircraft in the visual field without losing sight of it, resolving the contradiction between monitoring multiple aircraft and maintaining own aircraft identification.
Solution Approach 2:
The patent introduces an intermediary element (marker image) that is superimposed on the own aircraft in the head-mounted display. This marker acts as a visual mediator that highlights the own aircraft, enabling the pilot to maintain awareness of the own aircraft while monitoring multiple aircraft, thus preventing loss of own aircraft identification.
2Productivity
If the pilot takes eyes off the own aircraft to confirm aerially photographed images or operate remote control device, then the pilot can perform monitoring and control operations, but the pilot cannot see which aircraft is the own aircraft when searching for it
Solution Approach 1:
The patent applies preliminary action by pre-positioning the marker image on the own aircraft before the pilot needs to search for it. The marker is continuously displayed in the head-mounted display, so when the pilot returns their视线 from checking images or operating controls, the own aircraft is already identified through the marker, preventing collision risks and improving operational efficiency.
3Speed
If multiple aircrafts are moving at high speed in the air, then the aircrafts can cover distance quickly, but the pilot easily loses sight of the own aircraft
Solution Approach 1:
The patent uses color changes through the marker image that is displayed in the head-mounted display. The marker provides a consistent visual identifier on the own aircraft regardless of the aircraft's speed or position, allowing the pilot to maintain visual tracking and identification even when aircraft are moving at high speeds across the visual field.

AI summary
A transmission-type head-mounted display device includes an image display, a control section configured to control the image display section, a position detecting section, a visual-field detecting section configured to detect a visual field of the user, and a wireless communication section configured to perform wireless communication with an external apparatus. The control section includes a state-information acquiring section configured to acquire, via the wireless communication section, state information including a position of an own aircraft, which is a mobile body set as an operation target object of the user, and a support-information creating section configured to create, on the basis of a relation between the position and the visual field of the user and the position of the own aircraft, a support image including support information for operation of the own aircraft and cause the image display section to display the support image as the virtual image.
