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 within the detection

area until a certain timer value is reached, the Presence gesture is detected. The timer value is configurable. The

Presence gesture is typically used for lighting up backlights as if the hand is in the detection area and does not move;

a second timer is started.

Presence and Hold gestures are triggered upon a time-out in a defined Status flag. If a Status flag is active during a

certain amount of time, after its last rising edge, the corresponding gesture is triggered.
