Head-Mounted Display Heading Control for Marine Vessels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for controlling the heading of marine vessels lack efficient and intuitive methods for operators to adjust the vessel's direction, particularly in real-time, using wearable technology that integrates with the vessel's control systems.
Innovation Solution
A control system that includes a head-mounted display (HMD) with a sensor system to detect the operator's facing direction and a vessel control unit that adjusts the marine vessel's heading based on the operator's selection, allowing for precise control of propulsion devices and gimbal-mounted accessories.

Engineering Contradiction Analysis
1Productivity
If traditional manual control methods are used for adjusting vessel heading, then the control system is simple and reliable, but the operational efficiency is low and the control complexity is high
Solution Approach 1:
The patent replaces traditional mechanical control interfaces (steering wheels, levers) with a head-mounted display that uses sensor systems to detect operator head movements and facial expressions. This substitution of mechanical systems with sensor-based detection enables more efficient control while reducing the physical complexity of the control interface.
Solution Approach 2:
The system automatically detects the operator's facing direction and control inputs through sensors that monitor head position and facial expressions. The control unit processes these sensor signals and automatically adjusts the vessel heading without requiring manual manipulation of control devices, enabling the system to serve itself through automated detection and response.
2Ease of operation
If head-mounted display with sensor system is implemented for automatic heading control, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The head-mounted display acts as an intermediary device between the operator and the vessel control system. It contains sensor systems that detect head movements and facial expressions, then transmits these signals to the control unit which processes them and generates appropriate control commands. This intermediary structure simplifies the operator's interaction while managing the complexity within the electronic system rather than the mechanical interface.
Solution Approach 2:
The head-mounted display performs multiple functions: it detects facing direction, monitors head movements, captures facial expressions, and transmits control signals. By consolidating these multiple control functions into a single wearable device, the system improves ease of operation while containing the complexity within a unified multi-functional unit rather than requiring multiple separate control devices.
Data Source
AI summary
A control system of a marine vessel includes a vessel control unit that controls the rotational position of at least one rotatable device on the marine vessel, and a head-mounted display in data communication with the vessel control unit. The head-mounted display has a sensor system that detects a facing direction and a display positioned in the operator's field of view that displays an indicator of the facing direction. The head-mounted display also includes an interface element that allows the operator to select the facing direction. The control system operates such that the vessel control unit adjusts the rotational position of the rotatable device based on the facing direction.
