Mobile Terminal Tilt Control for Intuitive Marine Vessel Maneuvering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for remotely operating marine vessels using mobile terminals lack intuitive operability, making it difficult for users to maneuver the vessels effectively.
Innovation Solution
A mobile terminal detects its tilt from a neutral posture and transmits commands to generate propulsive forces corresponding to specific propulsion directions based on the detected tilt, allowing users to intuitively control the marine vessel's direction and force through tilting and touch operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional operation screens with buttons and controls are used for remote marine vessel operation, then the system structure is simple and easy to manufacture, but the operability and intuitiveness are poor
Solution Approach 1:
The patent replaces traditional mechanical control interfaces (buttons, switches, operation screens) with a mobile terminal that utilizes inertial sensors (accelerometers, gyroscopes) to detect physical tilting movements. This substitution transforms the control mechanism from manual button-pressing to intuitive physical gesture recognition, significantly improving operability while the modular software-based implementation keeps system complexity manageable
Solution Approach 2:
The patent changes the control parameter from discrete button selections to continuous tilt angle measurements. By detecting the tilt angle of the mobile terminal in multiple directions (pitch, roll, yaw) and mapping these continuous parameters to propulsion force magnitude and direction, the system achieves more natural and intuitive control compared to traditional discrete control interfaces
2Measurement precision
If complex operation interfaces are implemented to improve control precision, then the control accuracy improves, but the ease of operation deteriorates
Solution Approach 1:
The system utilizes the mobile terminal's built-in inertial sensors (accelerometers, gyroscopes) that are already present in the device for control purposes. By leveraging these existing sensors, the system achieves precise tilt detection without requiring additional specialized equipment, thereby maintaining ease of operation while improving control precision through accurate gesture recognition

AI summary
In an information processing method for remotely controlling a marine vessel using a mobile terminal, the mobile terminal detects that the mobile terminal is tilted from a neutral posture. Then, in response to detecting that the mobile terminal is tilted from the neutral posture, the mobile terminal transmits, to the marine vessel, a command for generating a propulsive force corresponding to at least one of a plurality of propulsion directions including a propulsion direction for translating the marine vessel in the front-rear direction, a propulsion direction for translating the marine vessel in the left-right direction, and a propulsion direction for turning the marine vessel in the left-right direction.
