End of time video acquisition [s]: this is the time between the end of the test and the end
of video acquisition (i.e., a certain number of extra seconds are recorded after the end of
the test).
Acquisition Format: allows you to choose the format for saving videos, which can be in ASF
(more compact and compatible with Windows Media Player), AVI (also compatible with
other players but less efficient compression) MJPEG or H.264 (the more compressed and
efficient). Plus, depending on the webcam connected, it allows selection of different
sampling resolutions (from the lowest 320x240 up to fullHD 1920x1080).
Preview First Step: If enabled, the Gait Test required a visual confirmation, via a pop-up of
the starting foot (see chap. 4.3.1.6).
Preview Time [sec.]: After this number of seconds the preview window is closed
automatically.
4.4.1.5 SPRINT/GAIT TEST CONFIGURATION
The configurations of this test type include:
Direction of entry: allows you to indicate if the Running/Gait entry direction is from the
‘interface side’ (drum) or from the ‘opposite side’. If ‘automatic’ is chosen, OptoGait
automatically calculates the direction, considering the LED nearest the centre of the foot as
the beginning of the LEDs.
Test Timeout [ms]: this is the test end timeout in milliseconds; if during a test with ‘Timeout’
stop type no input or output signal is received from the measurement area by the OptoGait
device for a period longer than or equal to the time set here, the test is considered
completed.
External signal hold off [ms]: is the hold off time between two consecutive external signals.
Caution has to be applied for this value, because it may depend on the type of test being
carried out.
Step length calculation: allows you to choose whether to calculate step length as the
distance between the tips of two successive feet or as the distance between the heels of two
successive feet.
