can be found in table 8.13 on page 160.
default Standard filtering without prediction or smoothing.
Flystick Recommended setting for use with a Flystick (responsive filter-
ing, designed for fast to slow motions).
HMD-1 Recommended setting for tracking of a HMD without hybrid track-
ing (down-tuned filtering with prediction, designed for fast mo-
tions).
medium prediction Filter with prediction of tracking data (less responsive filtering,
designed for slow to medium motion).
reference target Filter with smoothing for tracking of stable reference positions
(strong non-responsive filter, designed for occasionally moving
objects).
smoothing (delayed) Filter with strong smoothing and high averaging (responsive filter-
ing with high latencies, designed for recording of tracking data).
Presets hybrid tracking Description
hybrid custom Customizable preset. A detailed description can be found in table
8.13 on page 160.
hybrid default Standard filtering for hybrid targets without prediction or smooth-
ing (designed for e.g. Hybrid Motion Capture).
hybrid HMD medium prediction Filter for hybrid targets with prediction of tracking data. (designed
for e.g. HMDs)

It is also possible to customize the tracking behaviour to the requirements of the applica-
tion using the following tunable settings:
Settings Description Usage
Strength Sets the strength of the filter. Low
values lead to faster reaction but
higher jitter. High values result in
smoother output but slower reac-
tion. Note: Not available for hybrid
tracking. A higher strength may be
ideal for tracking seating
bucks
Prediction Predicts output for the specified
time into the future (ms) in order to
compensate tracking and rendering
latency. Note: Too high positive val-
ues can increase jitter and reduce
precision. Negative values can be
used for smoothing the output at the
cost of higher latency. A negative prediction may
be ideal for recording data
and offline analysis.
Mode optical
tracking Specifies the elementary behavior
of the filter.
Several options are
available:
for optical tracking only
’ Adaptive fast ’ Automatically adapts to the ob-
served motion. Moving targets that
change between fast and
slow motions, such as
Flysticks.
