The AirScan is a laser scanner device that measures distances in two dimensions. Thus, it allows for optical and contactless detection of objects or persons or just their hands. It can be used for any touch-less interaction with a display or a projected touch surface. In Widget Designer, our interactivity software, the AirScan is available as an optional input device and can be setup using the AirScanManager. It is possible to read up to 24 input points and use them for various applications within Widget Designer or Pandoras Box.

Measurement Principle and Restrictions

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 not be further away then 10m or 30ft. Longer distances (up to 65m or 200ft) can be set up, but will lead to a less accurate readout. The AirScan measures every 0.36 degrees if anything has crossed the scan area and transmits its data via TCP over network to Widget Designer for further data processing.

Please note the following restrictions to ensure correct usage and measurement readout:

- 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.

- Physical contact with the front cover of the sensor is to be avoided. Note that even a slight movement of the sensor affects the measurement values.

- If the AirScan is (partly) mounted into a wall or exhibition stand, make sure that the sensor (to be exact, the glass window) is not covered and the entire interactivity area is free.

- If a protective housing is provided for the sensor, the detection must not occur through additional window material (plastic, glass, etc.).

- Vapors, smoke, dust and all particles visible in the air could affect the measurement values.

- Glass and highly reflective materials such as mirrors could falsify the measurement value.

- Avoid large temperature fluctuations.

Drivers

When using the AirScan unit (AirScan Legacy), users can use the 'Auto Discovery' feature. This helps the user select from present devices and apply the respective IP Address.

It also helps to find AirScan Legacy instances that are configured to be in a different network (segment) that could otherwise not even be connected.

This way users also have the option to change the IP Address of the respective device to be in the scope of the production network (address range) so that the device can communicate with Widget Designer.

Precondition for autodiscovering AirScan units (AirScan Legacy) needs WinPcap or Npcap installed. If this precondition is not met, the Auto Discovery icon displays an exclamation mark and gives the following message: "Setting network details is disabled because the machine is missing WinPcap. Install WinPcap and restart the application in order to use this feature."
