Hey! Thank you for adding this page here, happy to explain everything.
We created it a while ago as a proof of concept - basically the idea was to apply the conductive grid to every page of the book. As we would know xyEnter and xyLeave of the finger, we could corelate this data to an actual content of the book. There would have to be some 'pairing' device though, we have tested few approaches, but not sure about this one. If someone would like to develop it further please feel free to message me at patryk.adas@gmail.com@JakeWesorick
The video you mention is post-produced to show the behavior - the fact that you don't need to actively use any external devices to actually save the content, as people usually take *pictures* of the text. We have envisioned it as 'swiping' the book, sort of.
