Interested in the OpenNI Initiative? OpenKinect? To learn more, read Josh Blake's Interview of Tamir Berliner of PrimeSense




Josh Blake, Deconstructing the NUI, 12/9/10



Josh Blake recently interviewed Tamir Berliner, one of the founders of PrimeSense.  If you haven't heard, Microsoft's Kinect was based on work by PrimeSense, and licensed their technology. PrimeSense provides consumer electronics with natural user interaction capabilities. The good news is that the company recently released open-sourced middleware for natural interaction and depth-camera drivers. It will be interesting to see how this will play in the near future!




In the interview, Tamir discussed a number of topics related to postWIMP technologies.  He also announced the newly created  OpenNI, "an industry-led, not-for-profit organization formed to certify compatibility and interoperability of Natural Interaction (NI) devices, applications, and middleware."   It is good to see this level of support for the cause!


Here is a quote from the interview that I especially liked:

"I believe that till today the devices we’ve been using, made us learn greatly lot about them before we could use them and gain their value. I’m pretty sure everyone who is reading this has got at least 3 remotes sitting on his living room table, and at least once a week needs to help someone use their computer/media center/phone/etc. It’s time for that to change and it’s up to us, the technologists to make this revolution happen, it’s time for the devices to take the step of understanding what we want and making sure we get that, even without asking if it’s a trivial task as opening a door when we approach, closing the lights when we leave the room, even making sure we have hot water to shower with when we return from work or wake up in the morning, depends on what we normally do." -Tamir

Here are a couple of videos from the OpenNI website that demonstrate OpenNI-compliant applications:

FYI: 
Josh Blake is the author of the Deconstructing the NUI blog. Over the past couple of years, he's explored natural user interfaces and interactions through his work on applications designed for Microsoft Surface and Win7 with Windows Presentation Foundation.
About a month ago, Josh organized OpenKinect, an on-line community to support collaboration among people interested in exploring ways to use Kinect with PCs and other devices.  An example of this effort is the open source code, libfreenect, which includes drivers and libraries for Windows, Linux, and OS X.

HACKED KINECT MULTITOUCH using libFreenect and libTISCH (via Florian Echtler)

MULTI-TOUCH WITH HACKED KINECT
Here is NUI-Group member Florian Echtler's  proof-of-concept HD video of using a hacked Kinect camera for multitouch-like interaction.  The application was built on Ubuntu Linux written using libfreenect, by marcan42  and Florian's creation, libTISCH.



Florian decided to use picture-browsing interaction to demonstrate proof-of concept, so "everybody can focus on more interesting things :-)"


(I have SO many ideas for this!  I'll throw a few out there in an upcoming post....maybe someone can run with them!)

Hacked Kinect taught to work as multitouch interface
Paul Miller, engadget, 11/11/10


FOR THE TECH-CURIOUS:
TISCH stands for Tangible Interactive Surfaces for Collaboration between Humans, and is a cross-platform, cross device multi-touch development framework.  You can download the source package for Windows, MacOS X, and Linux from the TISCH Sourceforge website. The Ubantu Lucid/Karmac version has "superquick installation via PPA" - the instructions can be found on the TISCH Sourceforge website.


LibFreenect- Open Source PC Drivers for Kinect

For your convenience, I've reposted something I wrote about libTISCH back in 2009:

For techies (and the tech-curious) who like technologies that support collaboration and multi-touch interaction,  this is great news!

Florian Echtler announced the first stable releas of libTISCH, a multi-touch development framwork, which can be found on Sourceforge.  TISCH stands for Tangible Interaction Surfaces for Collaboration between Humans.  libTISCH, a C++ software framework, is included in this project.  It provides a means for creating GUIs based on multi-touch and/or tangible input devices.

Here is how it works:

Architecture Layers



































Here is information from libTISCH announcement:

Highlights of this release are, among others, the following features:

- ready-to-use multitouch widgets based on OpenGL
- reconfigurable, hardware-independent gesture recognition engine
- support for widely used (move, scale, rotate..), pre-defined gestures
 as well as custom-defined gestures

- hardware drivers for FTIR, DI, Wiimote, DiamondTouch..
- TUIO converters: source and sink

- cross-platform: Linux, MacOS X, Windows (32 and 64 bit)
- cross-language: C++ with bindings for C#, Java, Python

libTISCH has a lot to offer for the multitouch developer. For example, 
the textured widgets enable rapid development of applications for many
kinds of multi-touch or tangible interfaces. The separate gesture
recognition engine allows the translation of a wide range of highly
configurable gestures into pre-defined or custom events which are then
acted on by the widgets. While the lower layers of libTISCH provide
functionality similar to tbeta, touche etc. (you can interface existing
TUIO-based software with libTISCH in both directions), it goes far
beyond.

More information about the library and underlying architecture can be found on http://tisch.sf.net/ and in the Sourceforge wiki at
http://sourceforge.net/apps/mediawiki/tisch/

I especially like the concept of the MeTaTop: "A Multi-Sensory Table Top System for Medical Procedures" that is linked from Florian's website.
