UAV Head-Mounted Direction Display for Intuitive Flight Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control methods for unmanned aerial vehicles (UAVs) primarily rely on accelerators of remote controllers, offering limited user experience and a single control method.
Innovation Solution
A control system that utilizes a handheld control device to obtain attitude information, determine control information, and send it to a head-mounted device to display a mark indicating the UAV's moving direction, enhancing user interaction and control intuitiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional accelerator-based remote controllers are used to control UAVs, then the control system is simple and easy to manufacture, but the user experience is poor and control intuitiveness is limited
Solution Approach 1:
The patent replaces traditional mechanical accelerator-based control with an attitude sensor-based control system that detects the orientation and posture of the handheld device. This substitution enables more intuitive control by leveraging the natural orientation of the device in space, transforming mechanical control into sensor-based spatial awareness control.
Solution Approach 2:
The patent introduces a head-mounted display as an intermediary between the controller and the UAV. This intermediary provides real-time visual feedback about the UAV's flight direction and position, enhancing the user's spatial awareness and control intuitiveness without requiring direct line-of-sight control.
2Adaptability or versatility
If a single control method using accelerators is used, then the control system is simple, but the user experience is poor and versatility is limited
Solution Approach 1:
The patent makes the handheld device serve multiple functions: it acts as both the control input device (through attitude sensing) and the display device (when worn on the head). This multi-functionality enhances versatility without requiring separate dedicated devices for control and display, thereby managing system complexity efficiently.
3Reliability
If no visual feedback is provided to the user, then the control system is simple, but the user cannot predict flight path and avoid collisions
Solution Approach 1:
The patent implements a feedback mechanism where the head-mounted display shows the UAV's flight direction and position in real-time. This visual feedback loop allows the user to continuously monitor the UAV's state and make informed control decisions, significantly improving flight safety and collision avoidance while managing system complexity through integrated sensor-display architecture.

AI summary
A control method for a movable object includes obtaining attitude information of a handheld control device; determining control information of the movable object according to the attitude information of the handheld control device; sending at least one of the attitude information or the control information of the movable object to a head-mounted device to cause the head-mounted device to display a mark on a display device of the head-mounted device, the mark indicating a moving direction of the movable object; and sending image information captured by a photographing device of the movable object to the head-mounted device to cause the display device of the head-mounted device to superimpose and display the image information and the mark.
