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!)

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
Xan Tium, XBLOG 360 11/10/10

Marcan is Hector Martin Cantero, the author of the Abort, Retry, Hack? blog.

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

libTISCH, a multi-touch development framework with multi-touch widgets and more!

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:

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/

Emerging Interactive Multimedia, New Models of HCI for Museum Exhibits (Course offered by Ideum's Jim Spadaccini, plus info about the MT55 multi-touch table)

Jim Spadaccini, the director and founder of Ideum, will be teaching a course on exhibit development through the University of Victoria, "Emerging Exhibits: Exploring New Models of Human Computer Interaction (HCI).  The excerpt from the course description provides a glimpse of how emerging technologies are beginning to change the museum experience:


"Computer-based interactive exhibits are undergoing a major transformation. The lone, single-user kiosk is now being replaced by multitouch tables and walls, motion-capture spaces, networked installations, and RFID-based exhibits. Advances in augmented reality, voice recognition, eye tracking, and other technologies promise even more radical change for exhibits in the near future."


I've been following Jim's journey with Ideum, a multimedia design firm that collaborates with museums and related non-profits, for many years, and I am impressed with the work of this company.  In addition to his work at Ideum,  Jim serves as the Principal Investigator of a National-Science Foundation sponsored open-source exhibit software project, Open Exhibits, which provides a free software development kit that supports the creation of multi-touch and multi-user software applications for museums and educational settings.


I'm happy to put in a plug for Ideum's latest product, the MT55 Platform Multi-Touch Table. It incorporates a range of features that I'm sure will meet the needs of museum visitors.  In my opinion, this table would be a fantastic resource for all types of libraries, including those in K-12 settings.

The MT55 Platform Multitouch Table from Ideum on Vimeo.  (Note: This video features music by Moby, the track "Sevastopol" on his current album, Destroyed. The music was used with the artists' permission. Learn more at: moby.com") - Ideum

"The thinnest, largest, most powerful multitouch table available.The MT55 Platform multitouch table houses a powerful computer and a 55-inch interactive LCD display that responds to 32 touch-points, inside a rugged aluminum body."

"The bright 55″ 1920×1080 HD display has a 5,000,000:1 contrast ratio. A wide 178-degree viewing angle accommodates multiple users around the table. The optical multitouch system supports 32 simultaneous touch points for collaborative interaction. The system is multitouch-enabled from start-up, and runs Windows 7 64-bit professional edition."


"The integrated computer is packed with power. It contains an Intel® Hyper-Threaded DualCore i5® which runs at 2.66 GHz, 8GB of RAM, and a 128 GB solid-state drive (upgradeable to an i7®)."


"The table comes complete with WIFI, Bluetooth, and Ethernet connectivity. It also has multiple HDMI outputs that allow you to easily mirror the table's display, extend the desktop, or connect to and display from another computer or HDMI device."

"Convenient, but secure ports: CAT5, HDMI, and USB 2.0 are available on both the side on bottom the table."

"The MT55 Platform includes blue LED under-lights to illuminate the area beneath the interactive surface (custom LED colors are available). Every MT table includes a sophisticated internal cooling cell to maintain operating conditions that exceed the optimum environmental specifications for the internal components."

"The interactive surface of the MT55 Platform protected by a sheet of hardened, crystal clear, low-iron 5mm tempered glass surface...As an option, we offer Sevasa HapticGlas®, produced exclusively for Ideum. Micro-etched HapticGlas® provides tactile feedback, reduces fingerprints, increases scratch resistance, and directs user focus." -Ideum

Multi-touch and Flash: Links to resources, revisiting Jeff Han's TED 2006 presentation

Despite the increase in interest in systems that support multi-touch, multi-user multimedia interaction, there is a need for creative, tech-savvy types to develop innovative applications. Why? This technology has the potential to make a powerful impact on how people learn, communicate, solve "big picture" problems, and do their various jobs.

CNN's Magic Wall was one of the first applications to gain the attention of the masses, as it was used as an interactive map during the US presidential election process. Touch-screen interaction gained even more notice after the recent SNL parody by Fred Amisen.

If you think about it, the multi-touch applications you see on the news aren't much different than what you'd get from a "single-touch" program.

Fancy, yes. Truly innovative, no.

Just imagine a 3D multi-touch, multi-user, multimedia version of Google Search. I did. I put my sketches in my idea book and hurt my brain thinking about how it could be coded.

Jeff Han, the man behind Perceptive Pixel and CNN's magic wall, had much more up his sleeve when he demonstrated his work at TED 2006. Even if you've previously seen this video, it is worth looking at again. (I've provided a link to the transcript below.)



Transcript of Jeff Han's TED 2006 Presentation

This video presentation had a transformational effect on me as I watched for the first time. Jeff Han brought to life ideas that were similar to my own as a beginning computer student thinking about collaborative educational games and multimedia applications that could be played on interactive whiteboards.

Here are some selected quotes from the video:

"I really really think this is gonna change- really change the way we interact with the machines from this point on."

"Again, the interface just disappears here. There's no manual. This is exactly what you kind of expect, especially if you haven't interacted with a computer before."

"Now, when you have initiatives like the hundred dollar laptop, I kind of cringe at the idea that we're gonna introduce a whole new generation of people to computing with kind of this standard mouse-and-windows pointer interface. This is something that I think is really the way we should be interacting with the machines from this point on. (applause)"

"Now this is going to be really important as we start getting to things like data visualization. For instance, I think we all really enjoyed Hans Rosling's talk, and he really emphasized the fact that I've been thinking about for a long time too, we have all this great data, but for some reason, it's just sitting there. We're not really accessing it. And one of the reasons why I think that is, is because of things like graphics- will be helped by things like graphics and visualization and inference tools. But I also think a big part of it is gonna be- starting to be able to have better interfaces, to be able to drill down into this kind of data, while still thinking about the big picture here."

So now what?

A recent post by "Alex", on the AFlex World blog discusses a few solutions. Alex had a chance to meet with Harry van der Veen and Pradeep George from the NUI Group, and Georg Kaindl, a multi-touch interaction designer from the Technical University of Vienna. The focus of the discussion was to come up with ideas to encourage Adobe/Flash designers and developers to learn more about multi-touch technology and interaction, and take steps to create innovative applications.

I especially like the following quote from the post:

"...A quick quote from our conversations: “When our children will walk up to a display, they will touch it and expect to do something.”

As a techie and a school psychologist, I see an immediate need for innovative applications. I know that there is a built-in market in the schools, at least for low-cost applications. Despite economic constraints, many school districts continue to invest in interactive whiteboards (IWB's). They are cropping up in preschool and K-12 settings, and teachers are searching for more than what's currently available.

Interactive, collaborative applications are needed in fields such as health care, patient education, finance & economics, urban planning, civil engineering, travel & tourism, museums & exhibitions, special events, entertainment, and more.

Smart Technologies, the company behind SmartBoards, has a new interactive multi-touch, multi-user table designed for K-6 education, the Smart Table. Hewlett Packard has several versions of the TouchSmart PC, which can support at least duo-touch, if not multi-touch, multi-user applications. There are numerous all-in-one large screen displays on the market that support multi-touch and multi-user interaction.

Quotes from Harry van der Veen, of Multitouch NL:

"In 10 years from now when a child walks up to a screen he expects it to be a multi-touch screen with which he can interact with by using gestures."

"...multi-touch screens will be as common as for children is the internet nowadays, as common as mobile phones are for us."


Here is a quote from a conversation I had with Spencer, who blogs at TeacherLED.

"It was interesting this week as I was in a classroom with a teacher who I've not worked with before... he had 2 students using the whiteboard who kept touching it together by mistake. The teacher, exasperated, said to himself, "Why can't they make these things to accept 2 touches without going crazy!"

Proof of the demand! I think you are right when teachers spot the limitations and then see the technology on visits to museums, that might stimulate demand."

Spencer creates cool interactive mini-applications, mostly for math, using Flash, that teachers (and students) love to use on interactive whiteboards. (He's interested in multi-touch, too.)


So what are we waiting for?!

Preview: Update on Touch & Multitouch Technologies, Websites, and Touch-Interactive Multimedia Apps

It is about time for an update about touch/gesture- interactive technologies.

I've been researching the latest in "touch" screens and new developments in interactive multi-media content.  In just one year, a multitude of websites have been transformed from static to interactive. 

Although the initial objective for some of these websites was to optimize the interface and navigation for people accessing websites via touch-screen cell phones,  some are ideal for use on touch-enabled slates, the iPad, and even larger touch screen displays and surfaces.   

Convergence seems to be the buzz word of the day.   Interactive TV.  Game sets with Internet access.  Movies on your cell phone.  Touch screen Coke machines displaying movie trailers.  What's happening now, and what is next?

I welcome input from my readers in the form of links to websites, university labs with grad students and professors who are obsessed with emerging interactive technologies, proof-of-concept video clips, video clips of related technologies that are new-to-market, etc.   

I will add video clips to the following playlist:

My Post-Wimp Explorer's Club YouTube Playlist 

FYI: I'm also in the middle of writing a series of posts about 3D television technologies for the Innovative Interactivity blog, and welcome input from my readers about this topic.

How to Build a 20" Multiitouch Screen in Three Weeks (Ben Unsworth - Globalcore)

How to Build a 20' Multitouch Screen in 3 Weeks from Ben Unsworth on Vimeo.


Globacore
Globacore used four 72" Blue Ocean Low Gain Screens 16:9 to create their twenty-foot multi-touch wall, which I think was also used for the "holographic" screen in the first video. The tracker and base flash API from the NUI-group were used in this system.
I wasn't sure if I'd heard about Blue Ocean screens.  Much to my surprise, the company behind Blue Ocean is Nippura, located in Japan.  Nippura has another office in Charlotte, N.C.
For years,  Nippura's core business has been focused on creating "the world's largest acrylic panels, tunnels, cylinders and spheres for the professional aquarium industry", but is also focused on screen systems as well.

US Nippura/Blue Ocean Projection Screens
Blue Ocean screens were use in the second videos of this post.  Below is some information the screens from the company's website:
"Blue Ocean® Projection Screens are the first ever to cast the screen into a hi-tolerance viewing plane centered between two ultra-clear panels of cell-cast acrylic, the same type of material used in hi-optic fighter jet canopies and the world’s largest aquariums. Blue Ocean® Projection Screens also offer something never before found in screens: self-rigidity.  The thickness of each screen can be fabricated so that it maintains its form without external frames or tension systems. Frameless high definition projected images without borders amplify the infinite depth viewing experience.  Because of its durability, outdoor applications of entertainment around the garden and pool are also possible. Normal wear and tear scratching has no long-term effect on the screens’ performance, and a ten year old screen, simply re-polished, will literally look and perform exactly as it did the day it left the factory."

STANTUM and GUNZE USA
Stantum has partnered with Gunze USA, a manufacturer of resistive touch-panels, to co-design and deliver multi-touch products.  "Gunze USA will provide these custom multi-touch modules to the North American market for use in industrial, automotive, defense, aerospace, medical, kiosk/point-of-sales, and other professional applications. Unlike capacitive multi-touch, Stantum’s technology is particularly well suited to these professional markets, thanks to its:

• immunity to EMI issues, via easy coexistence with Wi-Fi or Bluetooth antennas around the screen;
• stylus input and high precision, enabling handwriting recognition; and
• ability to work flawlessly with gloves."

According to the press release, Stantum's multi-touch technologies provide advantages such as handling 10 or more touches at a time, finger and stylus input, finger-pressure consumption, and native Windows 7 support, with no need for a driver. Developers can order the "beta" version of the Slate PC, based on the Dell Inspiron Mini netbook platform, from the Stantum website.

New multi-touch "Gravitoy" application from NUI; Multi-touch Space Invaders from Barcelona; "Open source" touch-less multi-touch SDK on CodePlex

NUI (Natural User Interface) recently unveiled Gravitoy, a multi-touch physics application that offers two modes of interaction. Below is a picture of children engaged in collaborative play on an interactive table running Gravitoy in the Sandbox mode. The children can draw objects that interact using principles of physics. (Photos are from NUI co-founder Harry van der Veen's blog)



Below are table-shots of the Sandbox mode:



See the triangle?

The second mode of Gravitoy is "Stacks". Two players play a game of stacking objects of various sizes. The difficulty level can be adjusted by changing gravity options.



This would make science lab engaging for students!

In addition, NUI developed a 3d model viewer application, which looks like it would be fun for budding architects and designers.

Visit the NUI website to learn more about the company and NUI's partners.

Take a look at Multi-touch Space Invaders from Multi-touch Barcelona. It looks like a fun game to play during a rainy recess:

Touchless Multi-touch...
I recently learned of another "open-source" touch-less "multi-touch" resource. The Touchless SDK was developed for a college project by a Columbia University student, Mike Wasserman.
You will need Visual Studio 2008, the code, and a webcam to get started. From what I can tell, the code will work with in the XNA development environment.

The Touchless SDK website has links to a video demonstration, demo code, FAQs, and more. The discussion list has a lot of good information.

Mike Wasserman is now working at Microsoft Labs.
