Located on the upper left are the buttons for establishing communication with the base station,
printout of test report and application preferences.

Panel with patient demographic information. More detailed patient information can be displayed, but
not altered.

This panel permits selection of the "Static tilt" or "Unilateral centrifugation" test mode. The
corresponding test sequence is selected and the measurement sequence is initiated. Relevant notes
can be entered and stored.

The upper right-hand area displays the real-time monitoring information on the luminous line, the
patient's button activity and the head sensor data. The left dial indicates the current angle of head
tilt, while the right dial indicates the angle of the luminous line. The deviation of the patient's SVV
estimate from the actual head tilt is visualized in the form of a slider. The displayed angle is
calculated as follows:
The polarity of the angles is defined from the point of view of the patient, i.e.:
Left (or Counterclockwise)
However the animation of the angle displays in the software application are configured according to
the clinical diagnostic tradition, i.e. inversely. Details on these conventions are included in the
Additional Information Manual.

The center of the screen displays the results chart for each measurement performed by the patient.
Results are plotted against the normal reference range. An optional display for the median value in
each tested position can be selected.

The individual test results (head tilt, SVV estimate) are entered in the table below the chart.

The status bar contains information on the current test sequence and on the battery capacity. The
help function, designated by the question mark in the lower right corner opens the PDF user manual.
