Issues and themes

Evaluating mirror behavior when the vehicle door is opened and closed.

It is seen in Plexlogger

By attaching an acceleration sensor to the door mirror and measuring displacement at the instant the door is closed based on the video, it is possible to ascertain the magnitude of the shock imposed on the mirror when the door is closed and the extent of the resulting movement.
