Summary: 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.
