You will observed a ball floating in a black sky through a halo.

Visual-Visual Instruction Sequence 2/7

Step 1: Straighten Head

If the halo is red you must reorient your head:

Look straight ahead then slowly tilt your head on your

shoulders. This will make the halo turn progressively from red to

green:

When the halo pops to bright green, hold this position.

Step 2: Acquire the Target Orientation

Once your head is aligned with your body (i.e. when the halo is

bright green), a set of parallel bars will appear at the end of the

tunnel, representing the target orientation.

Memorise the target orientation.

Note: Your hand must remain in the neutral position on your lap

throughout the target presentation. Please do not align your hand

to the target orientation during target presentation or during the

memory delay period.

Step 3: Tilt the Head

If the halo turns red, you must tilt you head to a new orientation.

The arrow tells you which way to rotate the head.

turns bright green and hold this position.

Step 4: Align to Remembered Target

With the left hand use the VR Headset Remote to align the

virtual tool to the memorised target.

Note: Press and hold RIGHT and LEFT on the VR Headset

Remote to rotate the virtual tool clockwise and counter-

clockwise, respectively.

Press the Select Button on the VR Headset Remote to

validate your response once you think that the virtual tool is

aligned with the memorised target.

Step 5: Check Response

In some of the trials a line of balls will be projected from your

hand towards the targets, allowing you to verify whether or not

you correctly aligned your hand. On other trials you will see

only a single spherical projectile without any indication as to

whether your hand was correctly aligned to the memorised

target orientation.

A green sphere appears briefly if the task sequence is

completed correctly, regardless of the accuracy of the hand's

alignment to the target.
