This paper evaluates MarkAirs, an interaction technique that uses fiducial markers to perform mid-air interactions. MarkAirs offers several advantages: the proposed technique does not require any tracking external hardware other than the front camera of a mobile device; it is robust even when the markers are partially occluded; and it enables precise 2D manipulations (translation, rotation and scaling). An evaluation study points to the feasibility and precision of the proposed technique and the perceived usability and subjective workload impressions of the participants.
