Interactive Tabletops and Surfaces: 2010 ACM Conference, Nov. 7-10, Saarbrucken, Germany. Wish I could go!

If you are new to this blog, you should know that I'm passionate about interactive tables and surfaces of all sizes!   Although this technology has been around for a while, it is a new concept to most people.  The researchers and practitioners involved in the upcoming 2010 Interactive Tabletops and Surfaces Conference have been an important influence in the way people think about interacting with technology, and have made significant contributions to this emerging field over the past several years.   It hasn't been an easy road, given that most of us have minds brainwashed through years of forced keyboard-and-mouse interaction and traditional WIMP (Windows, Icons, Menus, Pointers) interfaces.

I first learned about the first Interactive Tabletops conference, held in 2006, in early 2007.  At the time, I was working on projects for my HCI and Ubiquitous Computing classes, trying to learn everything I could about natural user interaction, large touch-screen displays, tabletop computing, and multi-touch.   I was inspired by the interesting work going on in this field.  This was before the first iPhone was introduced, before Microsoft's multi-touch Surface was unveiled, and three years before Apple broke out with the iPad.

Many of the people involved with the 2010 Interactive Tabletops and Surfaces Conference are (or have been) affiliated with the NUI group.  NUI stands for Natural User Interface, or Natural User Interaction - the NUI group is "a global research community focused on the open discovery of natural user interfaces."  I joined the NUI-group in 2007 when I was looking for more information about the nuts and bolts of multi-touch programming and systems, and have been encourage to see how things have evolved since then.

Members of another group, sparkon, are also participating in the Interactive Tabletops and Surfaces conference.  Sparkon is an on-line community that includes people involved with  interactive technologies, including tabletop and surface computing. "On sparkon, you'll find projects demonstrating the latest interactive techniques, applications, software frameworks, case studies, and blog articles relating to creative and emergent technology."  (I'm also a member of Sparkon.)


Here's the information from the conference website:

ACM Interactive Tabletops and Surfaces, Saarbrücken, Germany:  7-10 November, 2010
"ITS 2010 is a premier venue for presenting research in the design and use of new and emerging tabletop and interactive surface technologies. As a young community, we embrace the growth of the discipline in a wide variety of areas, including innovations in ITS hardware, software, interaction design, and studies expanding our understanding of design considerations of ITS technologies and of their applications in modern society. ITS 2010 will bring together top researchers and practitioners who are interested in both the technical and human aspects of interactive tabletop and surface technologies. It is our hope that we will be able to achieve increased synergy of approaches between the disciplines engaged in the research in the area of interactive tabletops and surfaces, Design, HCI, UbiComp, Psychology, MobileHCI and other related fields. More directly, we intend to encourage immediate interdisciplinary collaboration on future research topics. Young scholars and Ph.D. students are especially encouraged to submit papers and participate in the doctoral colloquium."

The Post-WIMP Explorers' Club: Update of the Updates, Morning of 12/31/09

What is the Post WIMP Explorers Club?  
I came up with the name of this semi-fictional club as a way to organize my thoughts (and blog posts) regarding the development of a new metaphor for post-WIMP applications and technologies, related specifically to natural user interfaces, natural user interaction design, and off-the-desktop user experience.  


Update, morning of 12/31/09:
Josh Blake, author of the blog "Deconstructing the NUI", posted Metaphors and OCGM  this morning.  It fleshes out post-WIMP concepts, addressing metaphors & interfaces.  The premise is that NUI metaphors will be less complex than GUI (WIMP) metaphors.    My feeling is that on the surface, this will hold true, especially for consumers/users and people creating light-weight applications and software widgets.  


Underneath the surface,  where designers and developers brains spend more time than users & consumers, things might be more complex.  Why? The technology to support the required wizardry is more complex.  With convergence, the creation of new technologies, applications, communication systems, and even electronic entertainment, is  now dependent upon the work and thinking of people from a wider range of disciplines.  Each discipline brings to the table a set of terms rooted in theory, and even research practices.

Update,  late afternoon, 12/30/09:

Richard Monson-Haefels response to Ron George's "Part 2".  The concept of OCGM might be growing on him now... OCGM: George's Razor : "If Ron George can explain how OCGM encompasses Affordances and Feedback than I'll be convinced that OCGM works for NUI. Otherwise, I think OCGM is a great start that would benefit from an added "A" and "F"." -Richard   

• OCGM relates to Occam's Razor.  It is helpful to read a bit about it if you are are interested in the post WIMP conversations. (The link is to an an article from "How Stuff Works", via Richard Monson-Haefel.)

UPDATE 12/30/09  -- This post is part of a discussion between several different bloggers, and was written before Ron George wrote his latest post, Welcome to the OCGM Generation!  Part 2, which I recommend that you read now, or within the same time frame, as this post.   Since I'm not ready to write "Part 2" of this post, I tweaked what I had and added some links to a handful of my previous posts that touch on this and related topics.  The links can be found at the bottom of this post.




START HERE FOR THE "ORIGINAL" POST FROM  12/29 & 12/20/09:


Background
About a year ago I responded to a conversation between Johnathan Brill, Josh Blake, and Richard Monson-Haefel discussing "post-WIMP" conceptualization regarding natural user interfaces and interaction, otherwise known as NUI.  The focus of the discussion was on Johnathan's post, "New Multi-touch Interface Conventions". At the time, we were reading Dan Saffer's book, Designing Gestural Interfaces, and contemplating new ways that technology can support human interaction and activities in a more natural, enjoyable, and intuitive manner.  

A few days later, I shared some of the concepts from the discussion on a post on this blog, "Why "new" ways of interaction?".  The post includes video of Johnathan Brill discussing PATA, a post-WIMP analogue to assist with multi-touch/gesture based application development, which he describes as follows:
Places
"Lighting, focus, and depth, simplified searching and effecting hyperlinked content."
Animation "Using animation to subtly demonstrate what applications do and how to use them is a better solution than using icons. Animations makes apps easier to learn."
Things "Back in the days of floppy disks, objects helped us organize our content. This limitation was forced by arcane technology, but it did have one huge advantage. We used our spatial memory to help us navigate content. Things will help us organize content and manipulate controllers across a growing variety of devices."
Auras "Auras will help us track what we are tracking and when an interaction has been successful."
(For reference, I've copied some of my responses to the first discussion, which can be found near the end of this post)


A year later....
What has changed?   Everything post-WIMP has been covered like a blanket by the NUI-word.  "NUI" now functions as a generic term for anything that is not exactly WIMP.  There is a sense of urgency now to figure out how best to conceptualize post-WIMP interfaces and interactions.  Newer, affordable technologies enable us to interact with friends and family while we are on-the go. Netbooks, e-Readers, SmartPhones, large touch screen displays, interactive HDTV, and new devices with multi-modal I/O's abound.  Our grandparents are on Facebook and twitter from their iPhones.  Our world no longer requires us to be slaves to the WIMP mentality.


So what is the problem?
The technology has moved along so fast that application designers and developers have not had a chance to catch up. (The iPhone is an exception.)  The downturn in the economy has made it difficult for many to take the leap from traditional software or web development and gain new skill sets.  On top of it all, most of us over the age of 15 have been brainwashed from years of working within the constraints of WIMP. It doesn't matter if we are users, consumers, students, designers, or developers.


Even the folks least likely to have difficulty expanding into the post-WIMP world have had some difficulty.  If you've had training in HCI (Human-Computer Interaction), you were inadvertently brainwashed with the best. The bulk of the theory and research you contemplated was launched at a time when WIMP was king, even as the Web expanded. Many of the of the principles held dear to traditional HCI folks have been shattered, and no-one has come up with a "theory of everything" that will cover all of the human actions and interactions that are supported or guided by new technologies.


The problem, in part, is that letting go of WIMP is hard to do, as illustrated by the following post from the Ars Technica website:  Light Touch:  A Design Firm Grapples with Microsoft Surface  (Matthew Braga, 6/29/09) "Ditching the mouse and keyboard means a whole lot more than just doing without two common peripherals.  As those who have worked with Microsoft Surface have found out, you have to jettison decades of GUI baggage and start with a whole new mindset...In actuality, few multi-touch gestures are really anything like what we experience in the physical world. There is no situation in which we pull on the corners of an image to increase its size, or swipe in a direction to reveal more content. So, in the context of real-world interaction, these types of gestures are far from natural...gestures should not only feel natural, but logical; the purpose that gestures like these serve, after all, is to replace GUI elements to the end of making interaction a more organic process."   (Be sure to read the comments.)

Now that the Surface is taking root in more places, and touch-screen all-in-one PC's and tablets are starting to multiply, more people are giving "NUI" some thought. Ron George, an interaction and product designer with experience working with Microsoft's Surface team has contributed to the post-WIMP discussion and spent some time sharing ideas with Josh Blake, a .NET, SharePoint, and Microsoft Surface Consultant for InfoStrat and author of Deconstructing the NUI blog. The outcome of this discussion was Ron George's December 28th blog post, "OCGM (pronounced Occam['s Razor] is the replacement for WIMP", and Josh Blake's post, "WIMP is to GUI as OCGM (Occam) is to NUI".   (Be sure to read the comments for both of these posts!)


OCGM (as conceptualized by Ron George)


Objects "are the core of the experience. They can have a direct correlation with something physical, or they can just be objects in the interface."


Containers "will be the “grouping” of the objects. This can manifest itself in whatever the system sees fit to better organize or instruct the user on interactions. They do not have to be, nor should they be, windows. They can be any sort of method of presentation or relationship gathering as seen fit."


Gestures "I went into detail about the differences in Gestures and Manipulations in a previous post [check it out for a refresher]. Gestures are actions performed by the user that initiate a function after its completion and recognition by the system. This is an indirect action on the system because it needs to be completed before the system will react to it."


Manipulations "are the direct influences on an object or a container by the user. These are immediate and responsive. They are generally intuitive and mimic the physical world in some manner. The results are expected and should be non-destructive. These are easily performed and accidental activations should be expected and frequent."

To illustrate a point regarding the validity of the OCGM analogy proposed by Ron George, Josh Blake shares the following video of a presentation from REMIX 2009, in which August de los Reyes, the Principle Director of User Experience for Surface Computing at Microsoft, briefly discusses the TOCA (Touch, Objects, Containers, and Actions) concept, suggested to replace the WIMP concept:

The video wouldn't embed, so go to the following link:


Predicting the Past: A Vision for Microsoft Surface
"Natural User Interface (NUI) is here. New systems of interaction require new approaches to design. Microsoft Surface stands at the forefront of this product space. This presentation looks at one of the richest sources for inventing the future: the past. By analyzing preceding inflection points in user interface, we can derive some patterns that point to the brave NUI world." 

The concepts outlined in the presentation are similar to Microsoft's Vision for 2019


Richard Monson-Haefel added his thoughts about the discussion about OCGM in his recent blog post, "What is NUI's WIMP?"  Richard disagrees with the OCGM concept, as he feels it doesn't encompass some important interactions, such as speech/direct voice input.   He'd probably agree that NUI is NOT WIMP 2.0.


Post-NUI, Activity Theory, and Off-the-Desktop Interaction Design:
As I was reading the recent posts and discussions regarding NUI/OCGM, I also contemplated some of what I've been reading over my holiday break, "Acting With Technology:  Activity Theory and Interaction Design", written by Victor Kaptelinin and Bonnie A. Nardi.   Victor Kaptelinin is the co-editor of "Beyond the Desktop Metaphor: Designing Integrated Digital Work Environments" (MIT Press, 2007), and has an interest in computer-supported cooperative work.  Bonnie Nardi brings to the IT world her background in anthropology, and is the co-author of "Information Ecologies:  Using Technology with the Heart" (MIT Press, 1999). The authors know what they are talking about. 


It is important to note that activity theory-based interaction design is viewed as a "post-cognitivistic", and informed by some of what I studied in psychology, education, and social science years ago. Within the field of activity theory are some important differences, which I'll save for a future post. 


Below are some concepts taken from the book. I am still mulling them over through the prism of NUI, post-WIMP, PATA, TOCA, OCGM, etc.  That's why there will be at "Part II", with specific examples.


"Means and ends, the extent to which the technology facilitates and constrains attaining user's goals and the impact of the technology on provoking or resolving conflicts between different goals


Social and physical aspects of the environment - integration of target technology with requirements, tools, resources, and social rules of the environment
Learning, cognition, and articulation,  internal vs external components of activity and support of their mutual transformations with target technology


Development -Developmental transformation of the above components as a whole" 
"Taken together, these sections cover various aspects of the way the target technology supports, or is intended to support, human actions".  (page 270)


I especially like the activity checklist included in the appendix of the book, as well as the concept of tool mediation. "The Activity Checklist is intended to be used at early phases of system design or for evaluating existing systems.  Accordingly, there are two slightly different versions of the Checklist, the "evaluation version" and the "design version".  Both versions are implemented as organized sets of items covering the contextual factors that can potentially influence the use of computer technology in real-life settings.  It is assumed that the Checklist can help to identify the most important issues, for instance, potential trouble spots that designers can address". (page 269)


"The Checklist covers a large space.  It is intended to be used first by examining the whole space for areas of interest, then focusing on the identified areas of interest in as much depth as possible...there is a heavy emphasis on the principle of tool mediation"  (page 270).


Other Thoughts
What is missing from this picture is a Universal Design component, something that I think holds up across time and technologies.  Following the principles of Universal design doesn't mean dumbing down or relying on simplicity. It is a multi-faceted approach, and relies on conctructing flexibility in use, one of the key concepts of Universal Design. I'd like to see this concept embedded in the post-WIMP conceptualization somehow. 


Because of my background in education/psychology/ special education, I try to follow the principles of  Universal Design for Learning (UDL) when I work on technology project.  I've spent some time thinking about how the principles of UDL could be realized through new interaction/interface systems.   Although this approach focuses on the educational technology domain, it is important to consider, given that a good percentage of our population - potential users, clients, consumers - has a temporary or permanent disability of one kind or another.


Components of Universal Design for Learning:
Multiple Means of Representation
Provide options for perception
Provide options for language and symbols
Provide options for comprehension
Multiple Means of Action and Expression
Provide options for physical action
Provide options for expressive skills and fluency
Provide options for executive functions
Multiple Means of Engagement
Provide options for recruiting interest
Provide options for sustaining effort and persistence
Provide options for self-regulation
-Adapted from the UDL Guidelines/Educator Checklist, which breaks down the components into more specific details.


Note:  The concept of Universal Design for Learning shares historical roots with some of the work behind Activity Theory and Interaction Design. Obviously, there is still much to contemplate regarding OCGM and other permutations of post-WIMP concepts!   


Here are my comments to the discussion on Johnathan Brill's blog from January 2009:
Thoughts: I'm seeing a trend to "optimize" WIMP-type applications so they can be manipulated by gesture and touch. People who program kiosks, ATM's and POS touch screens are examples of what I'm talking about. Touch and hold, two-fingered touch, and double-tap are just a slight transformation of the WIMP world-view, and in my opinion, are still WIMP (wimpy!). The mouse interaction "pretenders" are fine for using legacy productivity applications, OK in the short run.

For example, I have an HP TouchSmart, but I don't use the touch screen as often as I'd hoped. Try using using Visual Studio to code something on a touch screen. There is so much more that can be done! I know from the touch-screen prototype/demos I've worked on in various classes that applications that support collaboration and decision-making are important, and not just for work.

What do people DO, really? First of all, we are social beings, most of us. Think of what we share and discuss with others, and think about what sort of interactions on a display might best correspond with this interaction. Here are some of the things I've been DOING recently that involved some sort of technology and communication/collaboration with others:



---Travel planning - I recently went on a cruise and with various family members, selected activities I wanted to do on the ship as well plan my shore excursions (a complicated process)


---Picture sharing- I came back from the cruise with lots of pictures that I uploaded on Flickr. Related to this process: Picture annotating, tagging, choosing/comparing & editing it would be SO cool if I could use two sliders to enhance my pictures just so!


---Talking on the phone and responding to e-mail with friends and family members about the pictures, and what they wanted to see on Flickr- "you know, the ones of the dogs in Jamaica"... of which I had about 68!


---Financial planning with my husband. (I took info-viz last semester, so I know the possibilities are there.)


---Using the touch-screen to check-in at my eye-doctor's office: This was a user-unfriendly experience. Such a nice little screen. I was provided with a WIMPY PowerPoint-like interface which was confusing to use- and time consuming!


---Shopping at the new Super Wal-Mart: I asked the greeter if there was a map, and he said, "Food is over there, and the rest of the stuff is that way." Flat panel displays were all over the store, but of course,they weren't interactive. I had no idea where anything was, and the few items I was looking at had no bar-code tags. There wasn't a clerk in sight.   Wal-Mart TV rolled on-and-on via the display above my head. If I could only harness the display and have the talking head answer my questions! I gave up on my shopping trip when I was in the facial lotion/potion section. Too many choices, and too much fine print to read.

---Shopping at the mall with my young-adult daughters... I'll have to hold my thoughts on that one for now!

Some suggestions:
I think the artist/designers, (even dancers,) who are interested in multi-touch and gesture interaction have some interesting things to consider. (I linked to some of my previous posts.)


Again:
I am still mulling things over through the prism of NUI, post-WIMP, PATA, TOCA, OCGM, etc.  So that is why there will be at "Part II".  With specific examples!

More Multi-touch and Gesture-based Natural User Interfaces: Bamboo Wacom Tablet; Multi-touch PresTop Kiosk and Snowflake Suite software

Wacom Tablets Get Multi-Touch, Gestures
(Charlie Sorrel, Wired, 9/24/09)
"For the tech-curious, the new tablets have 512 pressure levels in the pen tip and the active area of the tablet is 5.8 x 3.6 inches, and all lose the in-pack mouse (for obvious reasons). The Touch and the Pen models are both $70, and the Pen & Touch is $100. Also, if you were thinking of buying Photoshop Elements 7 for the same price, get a tablet instead — Elements comes in the box."

I couldn't find any video clips of PresTop's multi-touch interaction. From what I can tell, PresTop multi-touch screens will be using SnowFlake Suite from Natural User Interface Technogies AB.

Without a single line of code, you can do quite a bit with Snowflake Suite

"This video covers how to make a rotatable and scalable image. The beauty about this is, that we have developed a Flash mouse input simulator, so that there is no need for multi-touch hardware in order to develop your applications. Simply simulate multiple mouse inputs for multi-touch.This project is still in alpha phase and a download will become available with the next release of Snowflake Suite 1.7 for the NextWindow platform and camera based multi-touch solutions."

DYI multi-touch...

If you follow this blog, you know I like to share what people are doing with multi-touch and related natural user interfaces/interaction. In this post, I'd like to share an article about two students who decided to build and market a multi-touch table- the article below explains the story in-depth, and video shows the nuts and bolts.


Enterprising roomates build multi-touch LCD, market their business to West Coast*
Walter Valencia, Collegiate Times 12/1/09

According to the above article, Aaron Bitler and Brady Simpson they were inspired by CNN's Magic Wall during the 2008 election.  Bitler and Simpson learned more about natural user interface/interaction during a presentation in a business class that featured a video about the Microsoft Surface table and natural user interface technologies.  They formed a company, 3M8,  to build and market mutli-touch display/tables.

Vision x32 from Aaron Bitler on Vimeo.

From what I can tell, it looks like Bitler and Simpson relied on the DYI information and support from the NUI-group website to carry out their ideas. Bitler and Simpson met with representatives of 22Miles, a company located in San Jose that provides interactive solutions, including multi-touch, for web, mobile, and touch screen implementations.

I'll post more about 22Miles in an upcoming post.

Until then, take a look at 22Miles' promo video, featuring a huge 3D interactive multi-touch heart:

More Multi-Touch from members of the NUI group!

It is always exciting to see what members of the NUI group are doing!

Here is a new video of a multi-touch creation by some of the members of the NUI group. Although this is a proof-of-concept example, it is fun to see how it is played out, using the little iPhone-like touch-pad widgets as a navigation tool for the large screen.


Read the "Multi-touch Goodness" article in Gizmodo of an interview with Christian Moore about this demo and his Lux open-source framework. (Christian is a colleague of Harry van der Veen, both members of the NUI group.)

Here is an excerpt from the interview:
"JD: Why Flash?
CM: Because it's fast to prototype in. However, the software is broken into several segments. One C++ application that tracks hands that talks to Flash... WPF... or another C++ app... and basically everything you can imagine. You can enable multitouch in any environment, like Cocoa."

High-resolution screen shots and additional information can be found on the nuiman website.

For my tech-minded readers:
I'm pretty sure that the C++ application that track hands and fingers in the video demo uses Touchlib, a library for creating multi-touch interaction. Touchlib can work with TUIO, a protocol for tabletop tangible user interfaces. Applications such as Flash and Processing support TUIO. For more information about TUIO, read "TUIO: A Protocol for Table-Top Tangible User Interfaces".
(Information from the NUI group website mentions that OpenCV, or Open Computer Vision Library, found on SourceForge, can support blog detection and tracking.)

The people behind TUIO are from the Reactable project, of the Music Technology Group at Pompeu Fabra University in Barcelona:

Here is my plug for the NUI group, once again!

"The NUI group, or Natural User Interface 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."


FYI
I came across the Harry van der Veen of the NUI group in early 2007 when I was working on touch-screen projects for my HCI and Ubicomp classes, and I'm inspired by all of the creativity I've seen coming from this group.

If you'd like to see more demos, visit the Natural User Interface website, a commercial out-growth of Harry and his colleague's work, where you can view a reel that includes a few touch-screen games. I love the vision statement on this site:

"Technology should enable us to interact with computers, in the same way we interact with the real world; in a way which is natural to us, namely through gestures, expressions, movements, and manipulations. Our vision is to change the way people interact with computers."

Interview: 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

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.
