The AirScan is a touch-less hardware interface that is available as an optional input device for Widget Designer and can be used for any touch-less interactions with a display or a projected touch surface. It is based on a rotation IR Laser field that allows to read two point multi-touch input gestures and use them for various applications within Widget Designer.

The AirScan unit can be mounted above, below or on the side of a screen and its recommended distance to the input screen area should be not further away then 10m or 30ft. Longer distances can be set up, but will lead to a less accurate readout. The AirScan measures every 0.36 degrees if anything has crossed the screen area and transmits its data via TCP over network to Widget Designer for further data processing.

Due to its IR laser technology, the AirScan device itself should not be exposed to direct sunlight or direct tungsten lighting as this would distort the correct readout of the sensed data.

AirScan Tool Setup in Widget Designer

airscan_setup_introOpen the AirScan tool from the Tools menu. In the AirScan setup tool you set up and connect to the IP address of the unit. Once connected you will see a yellow outline of the laser field. The input screen rectangle needs to be placed between a minimum and maximum range. All setup parameter related to the AirScan values are set in millimeters.

Once you got your touch data into the system you can map the first point to the local mouse and use one or more additional multi-touch points with a Multitouch Panel or an XY Panel.

The AirScan Tool is divided into several sections:

General Settings,
Input Point Processing,
Calibration,
Multipoint Mode
Mouse Control and the
Point Read-out.
