Display Laser During Hit - Interacoustics EyeSeeCam Instructions For Use Manual

The canal orientation can be selected from the Settings menu by selecting 3D Model. If the model is
enabled you can view it from any direction. You can also choose to have the model moving or static.

The canals are shaded with red to indicate activation and blue to indicate inhibition of the involved canals.
Figure 4.4.2-3 for a right lateral impulse, the right canal is activated and thereby shaded red and the left canal is
inhibited and thereby shaded blue.

Display laser during HIT

Before starting a test you can decide if you want to use an external target you place on the wall or if you
want to use the lights from the laser to project fixation targets for the patient to look at before and
between the impulses.
In the Settings tab there is a menu item to Display Laser during HIT. Here you can opt to have the laser
lights off or on during head movement. Some people will opt to use the center laser light as the target for
the patient to focus on at the onset of the impulse. If you choose to use a method for generating impulses
where the patient is rotated 45 degrees and gazing straight ahead, the availability of these laser dots will
eliminate the need for you to move the target on the wall. For Suppression Head Impulses (SHIMP) the
light will always be on.
