Research project for Hanwha Ocean
Role: design Research, user Research, UX Design, UI design, design for AI, mobility design
Team: designer(myself) and 1 hardware enginner, and 1 software engineer
Context: a research project at ARI Lab
Duration: June 2023 ~ current
Background
Background
A system for safe driving of transporter vehicles in shipyards.
Problem:
Collision accidents (vehicle vs. vehicle, vehicle vs. obstacle)
Signal crossing human casualties
Goal: Prevent close call collision accidents and signal crossing incidents with human casualties using lidar and camera sensors.

1st User Interview
Why Do Accidents Happen?
High-altitude accidents - Not the current focus of the project.
Miscommunication due to reduced cognitive abilities at night - A crucial point.
Approaching a situation recklessly, believing that one is skilled, leading to a close call or collision.
2nd User Interview
Derived Insights:
Workflow: Meetings -> JSA (Job Safety Analysis) -> Load, Transport - Unload - Another Meeting
Moving more than 40 items a day, sometimes up to 20 items even on light days.
Drivers need to assess the size of the cargo, somewhat like taking a cow from a rural area with you. Block sizes are estimated by sight due to extensive experience.
Drivers can estimate block sizes visually or by intuition.
Signals: Drivers use both visual signals and radio signals. Radio signals are necessary when the driver cannot see a person.
Sound alarms raise concerns as they cannot receive radio signals, which poses a safety risk.

Insights on Driving Situations:
While driving, the driver looks at the rearview camera, signals, and rearview mirror. They seem to check the screen once when loading and unloading. It feels like they only check the screen when loading and unloading, as there are too many screens, making it challenging to view.
While driving, drivers must perceive multiple elements at once - the rearview mirror, signals, and the road ahead. It's overwhelming with so much to watch.
In the navigation system, there's a screen showing the yard's layout.
It would be helpful if the screen displayed the shapes of the blocks - triangles, squares, and various shapes. Even a pop-up introduction to these shapes at the beginning of navigation could help users get a sense of width and size. By looking at the silhouette and identifying protruding parts, one can recognize hazardous areas.
While signals and other technologies can help balance the weight, different shapes require careful attention to specific areas.

Interview Content: The following draft presents a design direction for a screen that indicates the distance to obstacles while driving a transporter to prevent collisions with obstacles. Imagine driving with this screen in the driver's seat and freely respond to the following four questions:
How well do you perceive where the obstacles are located?
Do you think this would be helpful while driving, and if so, which type of screen do you believe would be most helpful?
What other features do you think are necessary?
Are you willing to use this?
