In this paper, we present PathSync, a novel, distal and multi-user mid-air gestural technique based on the principle of rhythmic path mimicry; by replicating the movement of a screen-represented pattern with their hand, users can intuitively interact with digital objects quickly, and with a high level of accuracy. We present three studies that each contribute (1) improvements to how correlation is calculated in path-mimicry techniques necessary for touchless interaction, (2) a validation of its efficiency in comparison to existing techniques, and (3) a demonstration of its intuitiveness and multi-user capacity 'in the wild'. Our studies consequently demonstrate PathSync's potential as an immediately legitimate alternative to existing techniques, with key advantages for public display and multi-user applications.
