FEATURE DESCRIPTION
2.1
Gesture Definition
A hand gesture is the movement of the hand to express
an idea or meaning. The GestIC technology accurately
allows sensing of a user’s free space hand motion for
contact free position tracking, as well as three-dimen-
sional (3D) gesture recognition based on classified
movement patterns.

COLIBRI SUITE
The Colibri Suite combines data acquisition, digital
signal processing and interpretation.
The Colibri Suite functional features are illustrated in
signal processing and interpretation.
The Colibri Suite functional features are illustrated in

Position Tracking
The Colibri Suite’s Position Tracking feature provides
three-dimensional hand position over time and area.
The absolute position data is provided according to the
defined origin of the Cartesian coordinate system (x, y,
z). Position Tracking data is continuously acquired in
parallel to Gesture Recognition. With a position rate of
up to 200 positions/sec., a maximum spatial resolution
of 150 dpi is achieved.

Gesture Recognition
The Colibri Suite’s gesture recognition model detects
and classifies hand movement patterns performed
inside the sensing area.
Using advanced stochastic classification based on
Hidden Markov Model (HMM), industry best gesture
recognition rate is being achieved. In addition, there
are some gestures derived from the combination of
Gesture Recognition and spatial information.
The Colibri Suite includes a set of predefined hand
gestures which contains flick, circular and symbol
gestures as the ones outlined below:
• Flick gestures
A flick gesture is a unidirectional gesture in a quick
flicking motion. An example may be a hand movement
from West to East within the sensing area, from South
to North, etc.
• Circular gestures
A circular gesture is a round-shaped hand movement
defined by direction (clockwise/counterclockwise)
without any specific start position of the user’s hand.
Two types of circular gestures are distinguished by
GestIC technology:

Discrete Circles
Discrete Circles are recognized after performing a
hand movement inside the sensing area. The
recognition result (direction: clockwise/
counterclockwise) is provided after the hand movement
stops or the hand exits the detection area. The Discrete
Circles are typically used as dedicated application
control commands.

AirWheel
An AirWheel is the recognition of continuously-
performed circles inside the sensing area and provides
information about the rotational movement in real time.
It starts after at least one quadrant of a circle is
recognized and provides continuously counter
information which increments/decrements according to
the movement’s direction (clockwise/
counterclockwise). The AirWheel can be adjusted for
convenient usage in various applications (e.g., volume
control, sensitivity adjustment or light dimming).
• Sensor Touch Gestures
A Sensor Touch is a multi-zone gesture that reports up
to five concurrently-performed touches on the system’s
electrodes.
The Sensor Touch provides information about Touch

Touch
The Sensor Touch indicates an event during which a
GestIC electrode is touched. This allows distinction
between short and long touches.
