Pointing in Virtual Reality
Description
Data from a study where participants pointed at one of 27 targets in the space in front of them. This version contains calibration poses, participant information, end the final pose for each pointing trial. The full dataset with all movement within each trial is available at https://github.com/TorSalve/pointing-data-ATHCC.
