Mouse, as a human-computer interaction device with very high frequency in daily life, is less used in ships, mainly because the ship sailing in the rivers, lakes and seas will be bumpy, especially when encountering bad weather, the bumps are very serious. The mouse, unlike trackball, cannot be fixed on the operating table and cannot be fixed and stored when it is bumpy. In order to further improve the crew's experience in the use process, this paper introduces a mouse device that can be used and stored on the ship. This paper describes in detail the design concept and process of the mouse device through the track recognition technology, photoelectric sensing processing technology, storage box fixation technology, etc., and environmental adaptability technology.
In order to further improve the versatility and serialization of the expansion keypad for ships, this paper details the design and implementation of a universal expansion keypad based on GD32, a microcontroller developed by a Chinese company, through hardware design, software design, universalization design and standardization design. The extended keypad designed in this paper can be applied to the current mainstream ship display consoles to further improve the versatility of the extended keypad. When different types of ships use customised extension keypads, only minor changes to the generic extension keypad are required to realise the corresponding functions, which greatly reduces the time and effort required for redesign and improves the versatility of the extension keypad.

In order to further improve the comfort of the lighting environment in crew cabins, this paper details the design and implementation of a ship's light environment control system. The ship light environment control system consists of a dimming lamp, a lighting sub-controller and a light environment control platform. The ship light environment control system is used to realize the internal lighting of the ship's cabins. Through the application of LED light sources, regionalized lighting technology and centralized control technology, the purpose of improving the cabin lighting environment, enhancing the functionality and comfort of lighting, and upgrading the level of lighting information is achieved. The ship light environment control system not only provides lighting for the interior of the cabin, but also has a corresponding human-machine interface for remote control and management of the dimming lamps.
