Hardware Section Intro...

[Taha]

The Natural User Interface and its influence on multi-touch gestural
interface design has brought about key significant changes in
computing hardware design, more specifically the creation of a “true”
multi-touch hardware system (i.e. support for more than two inputs).
The aim of NUI Group is to provide a platform where hardware and
software knowledge can be exchanged freely; and through this free
exchange of knowledge and information, there has been an increase in,
development on the hardware side of things.
On the hardware frontier NUI Group aims to be an informational
resource hub for others interested in prototyping and or constructing,
a low cost high resolution open source multi-input hardware system.
Through the community research efforts there have been improvements to
already existing multi-touch systems as well as the creation of new
techniques that allow for the development of not only multi-touch
hardware systems but also multi-modal devices.
At the moment there are five major techniques being employed by the
community that allow for the creation of a stable multi-touch hardware
systems; they are Jeff Han’s pioneering Frustrated Total Internal
Reflection (FTIR) approach, Rear Diffused Illumination (Rear DI) such
as Microsoft’s Surface Table, Laser Light Plan (LLP) pioneered in the
community by Alex Popovich also seen in Microsoft’s LaserTouch
prototype, LED-Light Plane (LED-LP) developed within the community by
Nima Motamedi and finally Diffused Surface Illumination (DSI)
developed within the community by Tim Roth.
These five of the major techniques being utilized by the community all
work on the principal of Computer Vision, where inputs are
extrapolated in real time by analysing a video feed/s through single
or multiple cameras. The use of computer vision to obtain and
extrapolate input data makes these techniques not only cost effective
and high resolution, but also makes them very scalable ranging in size
from 15inches up to or greater than 20 feet.

Hi Taha,

Many thanks for the introduction section. Where do you think it goes in the book? Since it tells about table techniques in general (and does not mention other hw related thing, i. e camera, projector etc), I'm not sure whether I should just put it right at the beginning of Hardware chapter.

For current status of the chapters and latest PDF file, please see http://wiki.nuigroup.com/Multitouch_handbook

Many thanks.

I haven't uploaded my recent work for the chapter(s)- I plan to do this around lunchtime, since I'll be with my dad this morning. 

 

Gorkem- I revised my work to address the items you outlined in a previous message.

I would put this in the begining of the hardware chapter then each of
the subchapters would be like FTIR, DI, LLP... etc i didnt really see
fit mentioning cameras or projectors since cameras are obvious when i
refering to computer vision, and for projectors or LCDs they should be
standard knowledge for IDC. what are your thoughts?

sorry this would go in the begining of the multitouch section As for
the hardware section i'll finish that off asap and put it up hereh

[Gorkem Cetin]

Ok, I fully agree with that.. I'm a bit of mobile, so will check later
today / tomorrow where it could really fit in multitouch section.

Many thanks.

Hi guys,
So the multitouch technologies section and the hardware section are
separate? Seth and I were talking yesterday and we were thinking they
should really be merged - first the hardware section which discusses
the various parts of the setups, followed by the descriptions/sections
about the technologies themselves - FTIR, LLP, DSI, DI. In order for
the reader to understand where the parts section is coming from,
Taha's intro would have to be at the beginning.

Does that make sense? What do you think?

Hmm well in the hardware part you will probably be mentioning certain
MT setups and vice versa so I guess make a call which one you want to
have the reader already have read, assuming they are reading
chronological.
