Abstract
We collected inertial sensor data on (i) a smart ring that was attached to the handle of an electric vehicle charging cable (representing an IMU embedded into the handle) and (ii) a smartwatch worn by the user on the same arm that he used to handle the charging cable. The data contains the unhook gestures and the plug-in gestures as users (n=20) unhooked a charging cable from a replica charging station and plugged it in to a replica vehicle, as would be done to charge an electric vehicle at a charging station. Both the charging station and vehicle fixtures were fitted with magnetic contact switches connected to Raspberry Pis which collected the timestamps whenever the charging cable was inserted into them; this list of timestamps is provided as a CSV file to retrieve the gesture data from the user files. Note that the 'Cable unstowed from charger' labelled timestamps are for the unhook gestures and the 'Car plugged in' labelled timestamps are for the plug-in gesture; the other labelled timestamps are for the returning of the cable back to the charging station
