airscan_drawing_usage

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 AirScan Tool. 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

airscan_measurement-drawing2
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

It is not necessary to install a driver. The communication between the AirScan and Widget Designer works over Ethernet and all necessary components come with the installation of Widget Designer.

AirScan Connectors and LEDs

airscan_with-connected-cables

Rear View with scanning direction going up: connections and LED indicators from left to right

Connectors

M12 plug / Connector1

For special applications and not to be used.

M12 socket / Connector2

For special applications and not to be used.

M12 socket / Connector3

This is the 100MBit/s Ethernet socket to connect a network switch or a computer. Use the supplied Ethernet cable with the 4-pin D-coded connector for the AirScan and the RJ-45 connector for the switch or computer.

The interface is configured with the IP address labeled on your device and the subnet mask is 255.255.255.0. Both can be changed with the "AirScan IP Configurator" which is available in the Download-Center on our web site.

M16 plug / Connector4

This is the power plug. Connect the supplied power cable with the 14-pin M16 connector to the AirScan and the XLR male connector to the XLR female connector of the low voltage power supply. Then connect its power cord. Note that the device powers on automatically and that there is no dedicated power switch.
