1. A method of activating a trigger mechanism at a data capture device having a touch display, and a data capture module, the method comprising: providing, on the touch display, a first region associated with a first application and an input region; receiving, at the data capture device, an input comprising at least a touch sensor input from the touch display; identifying, based on the input, an obtained input pattern comprising at least one of a spatial pattern, a temporal pattern, a touch size pattern and a hard-tap pattern, said hard-tap pattern based on a combination of the touch sensor input and a sensor input other than the touch sensor input; in a first mode of operation of the data capture device, when the identifying is successful, activating the trigger mechanism to initiate a data capture at the data capture module; and in a second mode of operation of the data capture device: when the identifying is unsuccessful, activating the trigger mechanism to initiate the data capture at the data capture module, and when the identifying is successful, changing the mode of operation of the data capture device from the second mode to the first mode.
