While pilot studies help to identify potential interesting research directions, the additional requirements in AR/MR make it challenging to conduct quick and dirty pilot studies efficiently with Optical See-Through Head-Mounted Displays (OST HMDs, OHMDs). To overcome these challenges, including the inability to observe and record in-context user interactions, increased task load, and difficulties with in-context data analysis and discussion, we introduce PilotAR (https://github.com/Synteraction-Lab/PilotAR), a tool designed iteratively to enhance AR/MR pilot studies, allowing live first-person and third-person views, multi-modal annotations, flexible wizarding interfaces, and multi-experimenter support.
