Development of the calibration tasks and associated procedures have used the ISO 26022 LCT, and ISO 17488 DRT to represent the primary task. While the calibration tasks described herein are intended to be applicable to other primary task implementations and dual task settings, care shall be taken to ensure that the conditions are sufficiently similar to those of ISO 26022 or ISO 17488 considering equipment and instructions to ensure a valid application of this document and its procedures.
There are various possibilities to realize a calibration task. In the following subclauses, three example alternatives are specified in detail. These alternatives include a system-paced secondary task (critical tracking task, CTT), a user-paced secondary task (surrogate reference task, SURT), and an auditory-vocal delayed digit recall task (n-back). Both the CTT and SURT alternatives represent visual-manual tasks that can be used in a dual task setting and are recommended as calibration tasks while using the LCT as the primary task. Whereas the n-back is a cognitive task that can be used in a dual task setting and is recommended as a calibration task while using the DRT as the primary task.
The participant controls the position of a vertically moving target bar with respect to a fiducial line (centreline) within a target area by manipulating up and down arrow keys. The arrow key control gives discrete commands to the target bar which moves it up and down. The up key moves the target bar up,and the down key moves it down.
The dynamics of the motion of the target bar are a first order instability. If the participant does nothing,the target bar moves (divergently) towards the edge of the display. The participant then has to make suitable corrective arrow key inputs to bring the target bar back towards the centre (the red dashed line in Eigure 1).ISO TS 14198 pdf free download.
