We are using the IR camera of the Kinect to make eye tracking at this price possible. You need a Kinect (and the USB adapter cable if it is the Xbox version), but they are available at craigslist and ebay below $ 100.
Both versions are supported. In case of the Kinect for Xbox version, the adaptor cable to convert to standard USB 2.0 has to be used to connect to the computer. The cable was included in the shipments of Kinect except certain bundles with Xbox. If it is missing, it can also be purchased e.g. at Amazon searching for "Xbox 360 Kinect AC Adapter/ Power Supply" currently for $ 7.79.
Currently Windows 7 / 8 are supported, but NUIA is designed platform independent to make it easy to port to Mac OS X / Android / Chrome OS / Linux etc. Our team has a strong Linux and Mac background - We definitely want to port and will decide where to start depending on the request for each OS.
Yes. Originally we wanted to add europe as free shipping area, but Kickstarter only offers to select the US as a separate free shipping area. Based on that, our production calculation is based on a bulk shipment to the US and shipping will happen from there. Help us making this the biggest german Kickstarter project ever and maybe Kickstarter will soon add more flexible shipping options.
Yes. The eyeCharm is a hardware clip-on and no changes are being made to the Kinect or the Kinect's firmware. The NUIA software is just directly to your PC. When you take the eyeCharm off, and plug the Kinect back to the Xbox, you can use it as before.
In addition to the C++ and C# binding and integration in .Net and Qt, the NUIA SDK comes with a generic C binding that can be used for Python as well as many other languages incl. Matlab, Java, Labview etc.
