Hi,
as we do have some confusion regarding Airscan, Airbars, Airtouch here some information about it:
We do talk about an Airscan and an Airtouch. The Airtouch is what some people know as Airbars, but oficially we call it Airtrouch.
The Airtouch is actualla a pair of two infrared LED Bars wich are pointing to each other as a Lightcurtain. They have a 3mm pixel pitch and will give us an information about the position where the curtain is “blocked”. So actually we do get 3 vaues out of them.
No.1: Left position
No.2: Right position
No.3: Distance between right and left position (Delta)
With the Airbars you can only track one dimension. So there is only a left to right, no up and down position. In the end you can do a lot of things with it like scaling, moving, rotating a layer. But they are always limited to one dimension. The setup is pretty easy. You have a controller box wich connects to the Widget Designer via USB. Into that controller box you plug the sender and reciever bar with a DIN cable. On the sender you will find a red and a green LED. As soon as the pair is setup right the LED will go from red to green. Thats all for setup. The rest is node programming in Widget Designer.
A good example of th Airtouch work is here: http://www.youtube.com/watch?v=JdKCiGN9n70
The Airscan is a bit more complex. It is a infrared laser scanner wich will scan the area in a 180° range. The scannig will only take place in one dimension, a bit like a lightcurtain again. But we do get much more information from the Airscan. We will see two points with an individual ID. Each point will have a x and y position. And we can get the Delta in between these points. So with the Airscan we can do a multitouch as well as a left right and up down position.
The Airscan connects to the Widget Designer with a Network Cable and needs to get an IP Adress in the same range as the Widget Designer. Then you will find a tool in the Widget Designer to configure the Airscan. There you can do a lot of settings, mainly to make a definition of the virtual touch screen size. So the angle and distance of the scanned area can be changed here.
As we do get much more information from the Airscan you can do a lot of things with it in the Widget Designer. Due to that the programming and setup is much more complex. And you need to adjust the Airscan settings on every venue as it depends on the distance and height from the mounted Airscan to your screen.
And here you will find a good example of the Airscan: http://www.youtube.com/watch?v=u_qB5jQTrSU
