TuioKinect, by Martin Kaltenbrunner: "A simple TUIO hand gesture tracker for Kinect"

More Kinect from Martin Kaltenbrunner:


Martin Kaltenbrunner's description of TuioKinect:
"TuioKinect tracks simple hand gestures using the Kinect controller and sends control data based on the TUIO protocol. This allows the rapid creation of gesture enabled applications with any platform or environment that supports TUIO tuio.org/​ You can download the application from: code.google.com/​p/​tuiokinect/​ Music: Jabon Jabon by El Club de los Astronautas (Institut Fatima)"


I've played around with Tuio and OpenFrameworks, but it has been a while.  I can't wait until I have time to dig into this with a Kinect. I think this has great potential for supporting learning and communication among students with special needs.

Xbox Kinect Interactive Puppet Prototype, from Theo Watson and Emily Gobeille (design.io) & Update on Funky Forest

I came across the following video on a post on the  Creative Applications blog about the Theo Watson and Emily Gobeille's  recent work with OpenFrameworks, Kinect, and an interactive puppet prototoype:

Interactive Puppet Prototype with Xbox Kinect from Theo Watson on Vimeo.

I'm not surprised that Theo Watson and Emily (design.io) decided to experiment with the XBox Kinect. I can't wait to see what they will create for Kinect in the future, based on their previous work --   A couple of years ago I wrote a post about their enchanting interactive installation, "Funky Forest":  OpenFrameworks & Interactive Multimedia:  Funky Forest Installation for CinKid. 


You can see from the video of their Funky Forest installation (2007 CinKid) that they create engaging interactive applications:

Funky Forest - Interactive Ecosystem from Theo Watson on Vimeo.
(Information from Theo Watson's Vimeo site)
"Funky Forest is a wild and crazy ecosystem where children manage the resources to influence the environment around them. By using their bodies or pillow "rocks" and "logs", water flowing from the digital stream on the floor can be dammed and diverted to the forest to make different parts grow. If a tree does not receive enough water it withers away but by pressing their bodies into the forest children create new trees based on their shape and character. As children explore and play they discover that the environment is inhabited by a variety of sonic life forms and creatures who appear and disappear depending on the health of the forest. As the seasons change the creatures also go through a metamorphosis."

"Kinect sound machines become prettier and easier with each development! The Kinect SoundWall is a drum beat music machine controlled by gestures and voice commands. This video by vertigosoftware displays this digital music machine at work and how through various gesture and voice commands, users can create awesome beats to dance to. In the video, the user gestures to to certain blocks in the screen in order to create a beat there or render the beats void. Through various voice commands, the beat can start, increase tempo, stop etc. Through the proper integration of both voice and gesture commands, the Kinect SoundWall sets the standard for a great and efficient sound machine of the Kinect!"

Here's Martin's description of the Therenect:

"The Therenect is a virtual Theremin for the Kinect controller. It defines two virtual antenna points, which allow controlling the pitch and volume of a simple oscillator. The distance to these points can be controlled by freely moving the hand in three dimensions or by reshaping the hand, which allows gestures that are quite similar to playing an actual Theremin."

Tech Product Placement & Embedded Advertising: Cisco Telepresence, Surface, Kinect, Windows 7 Phone, Apple, Apple iAd - Videos, Links - plus legal & ethical concerns

I was watching a DVR'd episode of NCIS tonight with my husband and noticed Cisco Telepresence video conferencing system was a player in the story line,  as well as a Cisco Cius touch-screen tablet.   It seems that on TV, laptops, desktops, and old-fashioned cell phones are history.    "Emerging" technologies are woven into the story lines of more television episodes,  including CSI, NCIS, Bones, Grey's Anatomy, and others.

The original intention of this post was to discuss the concept of emerging technologies and product placement/embedded advertising on television programs and movies, and share a few interesting examples related to his topic.  I quickly realized that there is much more to this story. Why?  More people access video and interactive multimedia content when they are on-the-go using laptops, smart phones, iPads, and similar tablets.   New televisions, such as Sony Internet TV, are internet-enabled, and many people already access the web content on their televisions through devices such as game consoles or Apple TV.

It is a marketer's dream. 

Unfortunately, we might not be ways to "opt-out" of all of the indirect (and direct) advertising that will come our way as we access video and related content across multiple platforms.   It won't be as easy as blocking pop-up ads or fast-forwarding the DVR!  

Below are some examples of ways some emerging technologies are "placed" in television/film, grouped by company.  In the "Apple" section, I've included video of Steve Jobs introducing iAds. Near the end of this post, I've included links that relate to ethical legal and ethical issues regarding product placement and embedded advertising.   

Food for thought.   I'm still digesting what I've found!

Xerox Patent Filing Make Product Placement Addressable
The Media Buyer, 1/12/10
"The patent describes the system (via GoRumors) as having the ability to alter content within a program based on the viewer. For example, if a character on a show mentions Macy’s, that content could be shown to general viewers. But that small portion of the broadcast could be “marked,” and the content could be changed so that the character instead says the name of sporting goods store Modell’s. That portion of the broadcast would be served to viewers who are into sports. Similarly, if the storefront was shown during the program, general audiences would see the Macy’s store, while sports fans would see the Modell’s store."

LibFreenect- Open Source PC Drivers for Kinect

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

How It Works: Microsoft's Project Natal for the Xbox 360 video from Scientific American


Microsoft gathered a wealth of biometric data to recognize the range of human movement in order to develop an algorithm for the next generation of controller-less gaming. "Natal will consist of a depth sensor that uses infrared signals to create a digital 3-D model of a player's body as it moves, a video camera that can pick up fine details such as facial expressions, and a microphone that can identify and locate individual voices."


The technology behind Natal has the potential for a range of uses beyond gaming.

Leap Motion: My Dev Kit Arrived - Now What?! Thoughts About "NUI" Child-Computer-Tech-Interaction - and More

My Leap Motion developer kit arrived last week. I carefully unboxed the small device and tried out the demo apps that came with the SDK.  I'm doing more looking than leaping at this point.

I'd like to create a simple cause-and-effect music, art and movement application for my 2-year-old grandson, knowing that he'll be turning three near the end of this year.  It would be nice if my app could provide young children with enough scaffolding to support gameplay and learning over a few years of development.

Now that I'm a grandmother, I've spent some time thinking about what the evolution of NUI will mean for young children like my grandson.   Family and friends captured his first moments after birth with iPhones, and shared across the Internet.  Born into the iWorld, he knows how to use an iPad or smart phone to view his earlier digital self on YouTube, without ever touching a mouse or a physical keyboard.

The little guy is pretty creative in his method of interacting with technology, as I've informally documented on video.   He was seven months old when he first encountered my first iPad.  It was fingers-and-toes interaction from the start.  

In the first picture below,  he's playing with NodeBeat.  In the second picture, he's 27 months old, experimenting with hand and foot interaction, on a variety of apps.

My grandson is new to motion control applications, so I'm just beginning to learn what he likes,  and what he is capable of doing.  A couple of weeks ago, we played River Rush, from the Kinect Adventures game. He loved jumping up and down as he tried to hit the adventure pins. Most of the time, he kept jumping right out of the raft!  (I think next time we'll try Kinect Sesame Street TV, or revisit Kinectimals.)  


One of the steps I'm taking to prepare for my Leap Motion adventure is take a look at what people have done with it so far.  There are at least 12,000 developer kits released, so hopefully there will be some interesting apps to go along with the retail version of Leap Motion when it is released at Best Buy on May 19th of this year.

One app I really like is  Adam Somer's AirHarp, featured in the video clip below:


I also like the idea behing the following app, developed by undergraduate students:

Social Sign: Multi-User sign language gesture translator using the Leap Motion Controller (git.to/socialSign)
 
"Built at the PennApps Spring 2013 hackathon, Social Sign is a friendly tool for learning sign language! By using the Leap Motion device, the BadApples team implemented a rudimentary machine learning algorithm to track and identify American Sign Language from a user's hand gestures."

"Social Sign visualizes these hand gestures and broadcasts them in textual and visual representations to other signers in a signing room. In a standard chat room fashion, the interface permits written communication but with the benefit of enhanced learning in mind. It's all about learning a new way to communicate."-BadApples Team

There are a few NUI-focused tech companies that have experimented with Leap Motion. Today, I received a link to the following videoclip Joanna Taccone, of Intuilab, featuring their most recent work:
Gesture recognition with Leap Motion using IntuiFace Presentation

"Preview of our work with the Leap Motion controller. In the same spirit as our support for Microsoft Kinect, we have encoded true gesture support, not just mouse emulation, for the creation of interactive applications by non-programmers. The goal is to hide complexity from designers using our product, IntuiFace Presentation (IP). Through the use of IP's trigger/action syntax, designers simply select a gesture as a trigger - Swipe Left, Swipe Right, Point, etc. - and associate that gesture with an action like "turn the page" or "rotate the carousel". As you can see in this video, it works quite well. :-) We will offer Leap support as soon as it ships." -IntuiLab



Below is a demonstration of guys playing Drop Cord, a collaboration between Leap Motion and Double Fine.  From the video, you can tell that they had a blast!  

Here is an excerpt from the chatter:  "The thing is that everyone just looks cool..Yeah, I know, it doesn't matter what you are doing...it's got the right amount of speed-up-slow-down stutter-y stuff...it is like a blend of art and science.."

According to the website, Drop Chord is a "A music-driven score challenge game for the Leap Motion controller, coming soon for PC, Mac, & IOS from the creators of Kinect Party.."  

The following video is a demonstration of the use of Leap Motion to control an avatar and other interaction in Second Life:

Comment:
I've been an enthusiastic supporter of natural-user interfaces and interaction for years - back in 2007 I worked on touch-screen applications for large displays as a graduate student, and became an early member of the NUI group.  I'm also a school psychologist, and from my experience, I understand how NUI-based applications and technologies, such as interactive whiteboards and touch-tablets, such as the iPad can support the learning, communication, and leisure needs of students who have significant special needs.   It looks like Leap Motion and similar technologies have the potential to support a wide range of applications that target special populations, of all ages.
