Advanced Tracking Calibration- Expression Units

The Expressions tab from the Advanced Tracking Configuration dialog only affects the ULSee tracker values.
We are considering in adding extra tracking configuration options for the other trackers too.

The Expression Units are used to fine tune the tracking based on your appearance and/or preferences. For
example, if you want your avatar to keep his eyes half closed, here’s where you can adjust the values to get
that result.

All expression units have a disable option so you can choose if you want the avatar to completely ignore
certain actions (for example pursed lips).

The Expression units tab has four subtabs: General, Eyes, Mouth and Retargeting.

Tracker Input Range shows the minimum and maximum values for different expressions. Min white bar
means minimum value and has a certain action linked with it (e.g. closed mouth), Max white bar represents
the maximum value and has the opposite action from the Max white bar linked to it (e.g. open mouth), and
the black bar is the actual value that the tracker outputs based on the user’s actions.
To adjust the interval just pull the sliders.

The facial expressions that have a LEFT and Right attribute can be linked together,
setting identical ranges for both of them by clicking Link to counterpart to toggle it on/off.

Jaw Drop – Specifies the interval between closed and opened mouth. When the black bar is over the “Min”
white bar both the avatar’s mouth and your mouth should be closed and when the black bar is over the Max
white bar, the mouths of both you and the avatar should be open.

Pursed Lips – Sets the interval for pursed lips. When the black bar is over the Min white bar both you and
the avatar should not have pursed lips and when the black bar is over the Max white bar, both you and the
avatar should have pursed lips.

Pursed Lips Left/Right – Sets the interval for pursed lips direction. Min white bar corresponds to pursed
lips towards the right and Max white bar corresponds to pursed lips towards the left. Pursed lips front (like a
kiss) is automatically set as 66% of the pursed lips left/right interval.

Opened Pursed Lips Left/Right – Sets the interval for open mouth pursed lips direction. Min white bar
corresponds to open mouth pursed lips towards the right and Min white bar corresponds to open mouth
pursed lips towards the left. Open mouth pursed lips front (like a kiss) is automatically set as 66% of the
open mouth pursed lips left/right interval.

Corner Depressor – Sets the interval for the mouth corners direction (happy>up and sad>down). If the
black bar is closer to the Min white bar then the avatar will smile while if the black bar is closer to the Max
white bar, the avatar’s mouth corners will give him a sad expression.

Lip Stretch Left – Sets the interval for the min and max positions of the left mouth corner. When you are
smiling, the value read by the tracker (the black bar) should be closer to the Max white bar (depending on
how big the smile is, it might even go further to the right than the Max white bar specifies). When your mouth
is in neutral position, the value read by the tracker (the black bar) should be either over the Min white bar or
as close to it as possible.

Lip Stretch Right – Sets the interval for the min and max positions of the right mouth corner. When you are
smiling, the value read by the tracker (the white bar) should be closer to the Max white bar (depending on
how big the smile is, it might even go further to the right than the Max white bar specifies). When your mouth
is in neutral position, the value read by the tracker (the white bar) should be either over the Min white bar or
as close to it as possible.

Upper Lip Raiser – Sets the interval for the min and max values for raising the upper lip. When in default
position, the value read by the tracker (the black bar) should be either on top of the Min white bar, or to the
left of the Min white bar. When the upper lip is risen, the value read by the tracker (the black bar) should be
closer to the Max white bar (if not on top of it, or more to the right, depending on how much your upper lip is
risen).

Lower Lip Drop – Sets the interval for the min and max values for lowering the lower lip. When in default
position, the value read by the tracker (the black bar) should be either on top of the Min white bar, or to the
left of the Min white bar. When the lower lip is pulled down and the teeth are showing, the value read by the
tracker (the black bar) should be closer to the Max white bar (if not on top of it, or more to the right,
depending on how much your lower lip is pulled down).

Nose Up/Down – Sets the interval for the min and max values for raising and lowering the nose. When in
neutral position, the value read by the tracker (the black bar) should be positioned in the middle between the
Min white bar and the Max white bar. The Min white bar represents the value for which the nose will be
completely lowered and the Max white bar represents the value for which the nose will be completely risen.

Eyebrow Left Interior – Sets the interval for the min and max values for raising and lowering the left interior
eyebrow. When you look angry (therefore the left interior eyebrow is at its lowest point), the tracker read
value (the black bar) should be the same as for the Min white bar (so the black bar should be either on top of
the Min white bar, or to the left of it). When have a surprised expression (therefore the left interior eyebrow is
at its highest point), the tracker read value (the black bar) should be the same as the one for the Max white
bar (the black bar should be either on top of the Max white bar or a bit to the right of it).

Eyebrow Right Interior – Sets the interval for the min and max values for raising and lowering the right
interior eyebrow. When you look angry (therefore the right interior eyebrow is at its lowest point), the tracker
read value (the black bar) should be the same as for the Min white bar (so the black bar should be either on
top of the Min white bar, or to the left of it). When you have a surprised expression (therefore the right interior
eyebrow is at its highest point), the tracker read value (the black bar) should be the same as the one for the
Max white bar (the black bar should be either on top of the Max white bar or a bit to the right of it).

Eyebrow Left Exterior – Sets the interval for the min and max values for raising and lowering the left
exterior eyebrow. When you look angry (therefore the left exterior eyebrow is at its lowest point), the tracker
read value (the black bar) should be the same as for the Min white bar (so the black bar should be either on
top of the Min white bar, or to the left of it). When you have a surprised expression (therefore the left exterior
eyebrow is at its highest point), the tracker read value (the black bar) should be the same as the one for the
Max white bar (the black bar should be either on top of the Max white bar or a bit to the right of it).

Eyebrow Right Exterior – Sets the interval for the min and max values for raising and lowering the right
exterior eyebrow. When you look angry (therefore the right exterior eyebrow is at its lowest point), the tracker
read value (the black bar) should be the same as for the Min white bar (so the black bar should be either on
top of the Min white bar, or to the left of it). When you have a surprised expression (therefore the right
exterior eyebrow is at its highest point), the tracker read value (the black bar) should be the same as the one
for the Max white bar (the black bar should be either on top of the Max white bar or a bit to the right of it).

Eye Left Pos Left/Right – Sets the positioning interval for the left eye iris. When you are looking directly at
the screen, the tracker read value (the black bar) should be in the middle of the interval determined by the
Min and Max white bars. When you are looking to the left, the black bar should be either on top of the Min
white bar, or a bit to the left of it. When you are looking to the right, the black bar should be either on top of
the Max white bar or a bit to the right of it.

Eye Right Pos Left/Right – Sets the positioning interval for the right eye iris. When you are looking directly
at the screen, the tracker read value (the black bar) should be in the middle of the interval determined by the
Min and Max white bars. When you are looking to the left, the black bar should be either on top of the Min
white bar, or a bit to the left of it. When you are looking to the right, the black bar should be either on top of
the Max white bar or a bit to the right of it.

Eye Left Pos Up/Down – Sets the positioning interval for the left eye iris. When you are looking directly at
the screen, the tracker read value (the black bar) should be in the middle of the interval determined by the
Min and Max white bars. When you are looking up, the black bar should be either on top of the Min white bar,
or a bit to the left of it. When you are looking down, the black bar should be either on top of the Max white
bar or a bit to the right of it.
