Triggering on hadronic tau decays is essential for a wide variety of analyses
of interesting physics processes at ATLAS. The ATLAS tau trigger combines
information from the tracking detectors and calorimeters to identify the
signature of hadronically decaying tau leptons. In Run 2 operation expected to
start in 2015, the trigger strategies will become more important than ever
before. In this paper, the tau trigger performance during Run 1 is summarized
and also an overview of the developments of Run 2 tau trigger strategy is
presented.Comment: LHCP Conference 201
