The Colibri Suite includes a set of predefined hand gestures which contains Flick, Circular and Symbol

gestures as the ones outlined below:

Flick Gestures

Figure 4-2. 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

Figure 4-3. Circle 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:

AirWheel

–

An AirWheel is the recognition of continuously-performed rotations inside the sensing area

and provides information about the rotational movement in real time. It 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).

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.

Hold and Presence Gestures

Hold/Presence gestures are recognized through the detection of a hand within a configurable detection

area. After the hand is detected as being present in this area, a timer will be started. If the hand stays
