Head-Mounted Display Switching for Safe Movable Platform Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ensuring the safety of movable platforms when interacting with head-mounted devices, particularly when displayed content changes, is challenging due to the difficulty in maintaining control and awareness of the platform's environment.
Innovation Solution
A control method for movable platforms that involves displaying images captured by both the head-mounted device and the platform on the device's display, with safety operation instructions generated when switching between these images to enable corresponding safety operations, such as maintaining position or returning, thereby enhancing user safety and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display device switches to display the first image (captured by head-mounted device) to provide user awareness of surroundings, then user safety and environmental understanding are improved, but the movable platform may lose control or collide with obstacles
Solution Approach 1:
The system performs preliminary actions by automatically executing safety operations (position holding, returning, or stopping) before the user can react to the environment change. When the display switches to the first image, the system proactively triggers safety protocols to prevent potential collisions, ensuring the platform maintains safe operations during the transition to user-awareness mode.
Solution Approach 2:
The system implements feedback by continuously monitoring display content changes and automatically responding with appropriate safety operations. The control method detects when the display switches between first and second images, and triggers corresponding safety operations based on this feedback, creating a closed-loop safety mechanism that adapts to real-time viewing needs.
2Ease of operation
If the display device displays the second image (captured by movable platform) to maintain platform control, then operational control is improved, but user awareness of surrounding environment deteriorates
Solution Approach 1:
The system dynamically switches between displaying the first image (for environmental awareness) and the second image (for platform control) based on operational needs. The display content is not static but adapts in real-time, allowing users to toggle between user-awareness mode and control-mode viewing, with each mode triggering appropriate safety operations.
Solution Approach 2:
The system uses the display device as an intermediary that mediates between the need for environmental awareness and the need for platform control. By switching display content between first and second images, the intermediary (display) allows users to access either environmental information or control information as needed, with the control system acting as another intermediary that translates display state changes into appropriate safety operations.
3Reliability
If the display device displays the first image to enhance user safety awareness, then user protection is improved, but platform operation stability deteriorates
Solution Approach 1:
The system executes preliminary safety operations (position holding, returning, or stopping) automatically when the display switches to the first image, stabilizing the platform before the user fully engages with the environmental view. This preliminary stabilization prevents operation instability while maintaining user protection benefits.
Solution Approach 2:
The system uses feedback from display state changes to automatically adjust platform operations. When the display shows the first image, the system receives feedback that user awareness is prioritized, and responds by executing stability-preserving safety operations, thereby maintaining operational stability even during user-protection mode.

AI summary
A method for controlling a movable platform includes: displaying a first image and/or a second image on a display device of a head-mounted device, where the first image is captured by a first photographing device on the head-mounted device and the second image is captured by a second photographing device on the movable platform; when switching from displaying the second image to displaying the first image on the display device, sending a safety operation instruction to the movable platform to make the movable platform perform a corresponding safety operation. This disclosure ensures the safety of the movable platform during interactions between the head-mounted device and the movable platform, particularly when the content displayed by the head-mounted device changes. The disclosure also provides a terminal device and a head-mounted device.
