Akari Nakano developed a passenger visualization enhancement for the tier4/autoware_launch repository, focusing on improving how passenger data is displayed within the RViz environment. By introducing a new YAML-based configuration file, Akari enabled more readable and useful visualization of passenger-related information, which supports quicker diagnostics and better operator situational awareness. The work leveraged ROS and RViz configuration skills, emphasizing a configuration-driven approach that simplifies future tuning and maintenance of visualization settings. Although no major bugs were addressed during this period, the feature delivered a targeted improvement to the Autoware visualization pipeline, demonstrating depth in both technical implementation and usability considerations.
