Michael Haller Discusses Multi-touch, Interactive Surfaces, and Emerging Technologies for Learning

I came across an excellent overview of interactive display technologies that hold promise for education. The link below is a research article written by Michael Haller for BECTA, formally known as the British Educational Communications and Technology Agency.

Emerging Technologies for Learning: Interactive Displays and Next Generation Interfaces(pdf)
Becta Research Report (2008) Michael Haller Volume 3 (2008)

"Multi-touch and interactive surfaces are becoming more interesting, because they allow a natural and intuitive interaction with the computer system.

These more intuitive and natural interfaces could help students to be more actively involved in working together with content and could also help improve whole-class teaching activities. As these technologies develop, the barrier of having to learn and work with traditional computer interfaces may diminish.

It is still unclear how fast these interfaces will become part of our daily life and how long it will take for them to be used in every classroom. However, we strongly believe that the more intuitive the interface is, the faster it will be accepted and used. There is a huge potential in these devices, because they allow us to use digital technologies in a more human way." -Michael Haller

Michael Haller works at the department of Digital Media of the Upper Austria University of Applied Sciences (Hagenberg, Austria), where he is the head of the Media Interaction Lab.

Michael co-organized the Interaction Tomorrow course at SIGGRAPH 2007, along with Chia Shen, of the Mitsubishi Electric Research Laboratories (MERL). Lecturers included Gerald Morrison, of Smart Technologies, Bruce H. Thomas, of the University oof Southern Australia, and Andy Wilson, of Microsoft Research. The course materials from Interaction Tomorrow are available on-line, and include videos, slides, and course notes.

Below is an excerpt from the discription of the Interaction Tomorrow SIGGRAPH 2007 course:

"Conventional metaphors and underlying interface infrastructure for single-user desktop systems have been traditionally geared towards single mouse and keyboard-based WIMP interface design, while people usually meet around a table, facing each other. A table/wall setting provides a large interactive visual surface for groups to interact together. It encourages collaboration, coordination, as well as simultaneous and parallel problem solving among multiple people.

In this course, we will describe particular challenges and solutions for the design of direct-touch tabletop and interactive wall environments. The participants will learn how to design a non-traditional user interface for large horizontal and vertical displays. Topics include physical setups (e.g. output displays), tracking, sensing, input devices, output displays, pen-based interfaces, direct multi-touch interactions, tangible UI, interaction techniques, application domains, current commercial systems, and future research."

It is worth taking the time to look over Haller's other publications. Here is a few that would be good to read:

Comment:
I became a fan of NextWindow touch-screen displays in early 2007 when I worked on a couple of touch-screen projects in my HCI and Ubicomp classes at UNC-Charlotte.

I've been using my HP TouchSmart PC at work with students with disabilities. I'm experimenting with the NUI Suite SnowFlake on my TouchSmart, and found that interacting with the Particles application delighted students with severe autism. The activities provided opportunities to establish joint attention. I also noticed an increase in the number of vocalizations and/or verbalizations among the students. Of course, this was NOT a scientific study.

Definition of Joint Attention from UConn:

"Joint Attention is the process of sharing one’s experience of observing an object or event, by following gaze or pointing gestures. It is critical for social development, language acquisition, cognitive development…"

Establishing joint attention is an important step in the development of social interaction skills among young people who have autism spectrum disorders.

Surface Flight Tracker Video from fboweb labs / flightwise.com, with background music by Art of Noise for your NUI pleasure.

This flight-tracker application for the Surface, looks fun to use. As I watched the video, I realized that it wasn't the application itself that I liked. It was the music that accompanied the video. The choice of music was from the 80's synth-pop band, Art of Noise

Since I'm a music lover, the music got me thinking.

Wouldn't it be great if productivity/work-related applications like Flight Tracker could be developed to provide a means for incorporating a sound-track?

Several thoughts and ideas flashed into my mind:

• Surface and related natural user interface/interaction (NUI) applications have the potential to transform routine, ho-hum work tasks into activities that are a bit more pleasant. Since people often listen to music while they work, it stands to reason that NUI productivity applications should incorporate a music component, at least as an option.
  

• To support a user-centered music platform for NUI applications, the application could incorporate a "smart" music library within the system, with the capability of integrating music libraries and playlists from user's mobile devices, as well as the web, effortlessly.(Of course, there are privacy/security and firewall issues to address, but that is another story.)
  

• Users could have a choice of listening to their own music playlists (including a shuffle option, selecting from a variety of presets, or go for something like the iTunes genius effect, listening to music generated from an algorithm that takes into account music preferences and user interaction with the productivity application over time.
  

• Since many Surface/NUI applications are designed to support collaborative work and interaction between two or more people, the music situation could get a bit complicated, since people have differing tastes. If co-workers disagreed about the music selection, the program would automatically default to generic elevator music, or silence.
  

• NUI applications might even pave the way for a new genre of music. This concept isn't too far-fetched. Think of all the music we've come to love over the years that was composed for movies and even video games!
  

If you know of anyone that is working on this concept, or would like to collaborate with me sometime in the future on this concept, please let me know. I'm slowly working on an interactive timeline prototype, and I have some ideas about adding a music/sound track component.

Connecting: Exploration of the Future of Interaction Design and User Experience - Good for promoting CSEd!

I've been looking for a relatively short video about human-computer interaction and related fields to include in a presentation I'm planning for high school students. The presentation is my small part to promote Computer Science in Education Week (CSEd). 

One of the goals of CSEd Week is to spread the word that computer science education is much more than learning how to program one. Technical and computational thinking skills are important to develop, but young people also need to know what sort of things they can do with these skills as they become adults in our technological society. As stated on the CSEd website, "Computing professionals work on creative teams to develop cutting-edge products and solutions that save lives, solve health problems, improve the environment, and keep us connected."  

Coincidentally, I was pleasantly surprised by a tweet I received today that linked to Connecting, a well-produced 18-minute video about interaction and user experience design. This video would be great to share with high school students.


Connecting (Full Film) from Bassett & Partners on Vimeo.

The video features a number of well-spoken, creative professionals who are passionate about their work, people, and the future.  Although the video is a bit techno-centric, it depicts people who live and breathe technology in a favorable light.  It also inspires some degree of thought and reflection on the part of the viewer.

Although much of what is discussed in Connecting is futuristic, the seeds were planted years ago.  If you are new to the HCI/UX/ID/UCD world, it might help to read
Mark Weiser's 1991 article, The Computer for the 21st Century, published in Scientific American in 1991, before viewing the video.  

After viewing the video, I encourage you to take the time to read some of the comments on the Vimeo website.  Also read  Marc Rettig's comments, posted on the IxDA website:  "A film about interaction design: what it says about us".  

Near the end of the video, there is a discussion about where we might be headed, as interconnected, technically enhanced, augmented humans.  Hopefully we will not create, and then be assimilated into a Borg-like collective, or live out our days in a Matrix-like disembodied state.

In the wrong hands, what might happen?

Is resistance futile?!

FYI: Connecting was produced by Microsoft, Windows Phone Design Studio: Mike Kruzeniski (now at Twitter), Kat Holmes, and Albert Shum, and featured interviews with the following people:

Matt Jones, BERG London
Raphael Grignani, Method
Liz Danzico, School of Visual Arts, New York
Blaise Aguera y Arcas, Architect of Bing Mobile and Bing Maps
Helen Walters,  Writer, Editor, Researcher at Doblin/Monitor
Younghee Jung, Research Leader, Nokia
Massimo Banzi, Co-Founder, Arduino
Jennifer Bove, Co-Founder, Managing Director, Kicker Studio
Robert Murdock, Principal, Method (Artefact)
Jonas Lowgren, Professor of IxD, Malmo University, Sweden
Eric Rodenbeck, CEO, Founder, Creative Director, Stamen Design
Robert Fabricant, VP of Creative, Frog Design
Andrei Herasimchuck, Twitter 

The video was first screened in Seattle, Washington, last April, with a panel discussion that included Rob Girling and Gavin Kelly, of Artefact, Bill Buxton, of Microsoft, and Scott Nazarian, of Frog Design.

Description of the "Connecting" video, from Bassett & Partners' Vimeo site:

"The 18 minute "Connecting" documentary is an exploration of the future of Interaction Design and User Experience from some of the industry's thought leaders. As the role of software is catapulting forward, Interaction Design is seen to be not only increasing in importance dramatically, but also expected to play a leading role in shaping the coming "Internet of things." Ultimately, when the digital and physical worlds become one, humans along with technology are potentially on the path to becoming a "super organism" capable of influencing and enabling a broad spectrum of new behaviors in the world." -Bassett & Partners

Selected Quotes:

Liz Danzico:
"It's understanding that ecosystem, where the human in the center, and understanding that network of things, and how they all work together, rather than of your device or thing being in the center."

Younghee Jung:
"... you can not necessarily foresee the consequences when people adopt what you designed..to see something completely different from what you created. .it is like throwing a stone in the water, and you don't know what it will cause."

Blaise Aguera y Arcas:
"....these are all augmentations of abilities as humans. And when the augmentation really works, then that extension of yourself feels natural, and beautiful and does what you want, and doesn't get in the way....The use of voice, and the use of natural gestures... you are removing the extraneous, you are removing the artificial."

Massimo Banzi:
"...Something that can do it's own thing, disappearing in the background, is correct"  (nod to Weiser)

Jennifer Bove:
"...it is really important to look at what the consequences are of putting these products into the world when we think about things like the phone...the way it has changed our behavior, it can be enabling, and also disrupting...for these things to change our lives for the better, or enable for them to let us do things we couldn't do before.. they have to feel natural, and feels like a conversation." 

Robert Murdock:
"How you actually design and enact a living system in UX is something that is quite challenging...you have to think about patterns of desired outcomes and behaviors you want to achieve, instead of moving a user through one flow in an experience."

Jonas Lowgren: 
"...back in the day.. it was one user, one task, one computer,  its all gone now, its is much more like you are setting the stage, really,  for other people to perform, but you can never tell them what to do."

Eric Rodenbeck:
"....the map is like a living thing, that is being made up of everything we got. The idea that it is different in the morning than what it was in the evening, is a really good idea to stay connected to the idea that the world is changing."

Helen Walters:
"What we need is for designers to be embedded in the topics that are really, really important right now, so there can be a better synergy between design, and business design, and social change design, and entrepreneurship."

Andrei Herasimchuck
"That is where the future lies with us. There will be software in everything..You can take all of those (digital) pieces, and you can design all kind of things around it. People are now actually entering their lives and what is going around them, into a digital format, and so we will start do things with that in the future, and I think it will be exciting."

Robert Fabricant:
"The network is sampling the world, and knowing what is cropping up where, being able to match and find patterns...and anticipate outbreaks of diseases. ..  We are trying  now to collect from the periphery a much richer set of what is going on the world so we can learn as a society and optimize and evolve the right systems and services".

Look, touch, listen, and play: Seth Sandler's Interactive Audio Touch Table Video; NUI Group and Google's Summer of Code

Seth Sandler's most recent video of the Audio Touch interactive table provides a good demonstration of how multi-touch on a table can work with music.



Seth is a member of the NUI group (Natural User Interface). He is finishing a Bachelors degree in Interdisciplinary Computing and the Arts, with an emphasis on Music, at the University of California, San Diego. His research and development work centers around multi-touch, multi-user musical interfaces.

Here is an update about the NUI group:

"Natural User Interface or ~ NUI Group is an interactive media group researching and creating open source machine sensing techniques to benefit artistic and educational applications."

"We offer a collaborative environment for developers that are interested in learning and sharing new HCI (Human Computer Interaction) methods and concepts. This may include topics such as: voice/handwriting/gesture recognition, touch computing, computer vision, and information visualization."

The NUI group has been selected for mentoring organization for Google's Summer of Code, for those of you who are interested in working on open-source code for multi-touch systems. The student application process begins Monday, March 24th, 2008, and ends Monday, March 31st, 2008.

NUI group's project ideas page outlines the requirements for the application, which includes a 7500 word project proposal. The project page has a long list of ideas to spark some thinking for potential Summer of Code applicants.

For those of you who aren't into coding, I encourage you to take a look at the NUI Groups project ideas page just to get an idea of th interesting ideas that are being explored. The page has a list of links to other good resources.

Share the word with anyone who might be interested in the NUI Group's projects for the Summer of Code. We need to get more people interested in STEM careers, and the project ideas outlined by the NUI group look enticing.

Interactive Displays and "Billboards" in Public Spaces; Pervasive Displays 2013

The 2013 International Symposium on Pervasive Displays (PerDis 2013), recently convened  in Mountain View, California.  Since I couldn't attend this conference, I was happy to learn from Albrecht Schmidt that the conference proceedings were recently uploaded to the ACM Digital library.  There are many exciting things going on in this interdisciplinary field!

Researchers involved with the Instant Places project, described in the video below, presented their work at PerDis 2013. The Instant Places project was part of PD-Net, a series of research efforts exploring the future of pervasive display networks in Europe. (See the "Related" section for additional references and links.)


Instant Places: Tools and Practices for Situated Publication in Display Networks

Below is information from the Instant Places video and website:
"The video describes a novel screen media system that explores new practices for individual publication and identity projection in public digital displays." 

"Instant Places has been developed by the Ubicomp group of the Information Systems Department, at the University of Minho, and has been funded within the scope of pd-net: Towards Future Pervasive Display Networks, by the European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement no. 244011."

Saul Greenberg was the keynote speaker at PerDis 2013.  His keynote, "Proxemic Interactions: Displays and Devices that Respond to Social Distance", highlights how far off-the-desktop our digital/physical lives have become, and how this has influenced recent research in human-computer interaction. Saul is a professor at the University of Calgary and leads research in Human Computer Interaction, Computer Supported Cooperative Work, and Ubiquitous Computing.

Although the video of Saul Greenberg's presentation below is not from PerDis 2013, it touches on the same topics and is worth taking an hour to watch.  In this video, Greenberg presents an overview of the history of human-computer interaction. He also offers up a discussion how an understanding social theory, perception of spatial relationships, and embodied interaction can be applied to the design of natural user interfaces and interactive systems.  Useful examples of interaction design explorations, within an ecological context, are provided later in the video.

My Backstory

Regular readers of this blog know that to subject interactive displays in public spaces holds my interest. When I was taking computer courses during the mid 2000s, I focused some of my energy on projects designed for large interactive displays, inspired by reading articles like "Physically Large Displays Improve Performance on Spatial Tasks" (Desney S. Tan, Darren Gergle, Peter Scupelli, and Randy Pausch) and "Dynamo: public interactive surface supporting the cooperative sharing and exchange of media" (Shahram Izadi, Harry Brignull, Tom Rodden, Yvonne Rogers, Mia Underwood).  

Jeff Han's 2006 TED talk was another inspiration. I remember my excitement as watched his demonstration of an interactive multi-touch touch screen the size of a drafting board, before the iPhone/iPad was born.  Another inspiration was Hans Rosling's TED Talk  about health statistics, with his animated interactive data visualizations presented on a huge screen.

The following year, I stumbled upon the  NUI-Group while searching for information about multi-touch displays, and was inspired by many of the early members of the group.  I also became acquainted with a world-wide network of people who share similar interests, such as Albrecht Schmidt and his team of researchers at the Unversity of Stuttgart. This busy group recently presented at PerDis 2013 and at CHI 2013 and are involved in a wider range of ongoing projects.

Sensory-Mind's Ring Wall, an interactive multi-touch wall you don't even have to touch!

Sensory-Minds is a small company in Germany that is focused on research and design in the field of Natural User Interfaces. If you visit the SENSORY-MINDS website, you'll find that it has been designed for touch interaction.

ring°wall from SENSORY-MINDS on Vimeo.

Information about the Ring Wall from Sensory-Mind's Vimeo site:

".....The two-piece ring°wall consists of a LED display and a multitouch information-wall and impresses by its size: a total surface of 425 square meters, which equals more than 6000 computer displays, is the biggest of its kind. An interactive World emerges out of 34 million pixels generated by 15 high definition projectors and is supported by 30 directional speakers.


Multitouch sensors basing on laser technology, convert the usage of the natural user interface into an experience. By direct touching, more than 80 users can simultaneously get informed about news and activities around the ringworld.


The interactive wall is not only a central information system, but also an innovative advertising tool and medium for public viewings."

Heiko Hoffman of Sensory-Minds recently joined the NUI-Group.  Here is a response to a question on the NUI-group forum about the way the system's sensors work:


"The sensor works like spinning radar gun, or like a wiper in a car, that means like a radar gun you get the distance to the object.  It’s not quiet difficult when you know the position of the sensor and the degree from the beam to get the X,Y position.  Yes, you don’t need to touch the surface but we arranged it that the radar beam is very close to the screen so it seems that you have to touch the surface.

At the moment the system (has) limitations because each sensor (gets) coordinates and this means that you got shadows.This is no problem because the people interact very fast. We are working on a system where the data from the sensors were put together and that would be the solution for this problem."


Note:

I'll be writing a few more posts updating the work of past and present NUI-group members as well as news from the commercial multi-touch & gesture community.  Be sure to check back soon, or subscribe to this blog!

In my first post, I discuss interactive technologies in education and the explosion in the number of interactive whiteboards making way in classrooms in the US and around the globe.   The motivation for this post came from last week's announcement of Smart Technologie's acquisition of NextWindow.  Not long after the announcement, I had a chance to speak with Al Monro, CEO of NextWindow, and Nancy Knowlton, CEO of Smart Technologies. I share some of their insights in my post:

SMART Technologies' acquisition of NextWindow: A "smart window" to the world

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.

A few links: GizmoWatch's 10 Interactive User Interfaces for the Future, CNN's Eatocracy, EVA 2010 and More!

Here's a quick link to a recent Gizmowatch post, Ten Interactive User Interfaces for the Future.  Bharat, the authro, reviews a variety of interfaces, input methods, and interaction techniques, such as Skinput, a water-based touch screen, a muscle-computer interface, air gestures, brain-computer systems, and even a mud-tub interface.


I was fortunate to see some of these interaction techniques and interfaces when I attended CHI 2010 this past April, and plan to share some of my photos and video clips from the conference on this blog soon.

Eatocracy is a new website within the CNN pages that provides news- and more- about all things related to food. The categories on the site include "main", "news", "bite", "sip", "make", "think", and "buzz".  The best part, in my opinion, is the heirloom recipe collection index, where people can upload and share family recipies and the stories behind them.

Here is the description of Eatocracy from the website:

Eatocracy  "is your online home for smart, passionate conversation and information about food news, politics, culture. We'll highlight regional and family recipes, dive into restaurants and food shopping, chat with celebrity and local chefs, and show you what's for dinner around the world tonight. Grab a place at the table and read with your mouth full."

Enjoy!

FYI

I'm in the process of sorting through and re-organizing my blogs, which have been around for over four years!  During this time, my blogs have attracted a growing number of readers. Because of this, I'd like to make things a bit user-centered.  So expect to see little changes here and there.  I promise I'll give my readers warnings in advance if I make any serious changes! 

If you are new to this blog, you should know that my blogs started out as on-line filing cabinets, open to the world.  Although there is a bit of overlap of material and some cross-posting between the blogs, they are arranged to serve as a paper-less way of keeping track of things that I've learned through my coursework, conference attendance, readings, and research. Since emerging technologies are high on my list of interests, I also use my blogs to share interesting things that cross my path.    

  

I changed the name of my World Is My Interface blog to The World Is My Interactive Interface.   "Off-the-desktop natural user interfaces, interaction, and user experience" are the main topics of the blog.  It sometimes includes information about ubiquitous computing and DOOH, otherwise known as Digital Out Of Home.

I plan to tinker with my TechPsych blog later on. It focuses on topics that are useful to psychologists, educators, special education teachers, speech and language therapists, health and wellness professionals, and parents.

Feel free to leave comments, as I welcome your input.
