Building a High-Resolution Multitouch Wall (Part 1)

For the latest installments see: Building a High-Resolution Multitouch Wall (Part 2), Building a High-Resolution Multitouch Wall (Part 3) , Building a High-Resolution Multitouch Wall (Part 4) and Building a High-Resolution Multitouch Wall (Part 5).

We’ve just begun work on our most ambitious installation to date: a 7′ round, high-resoultion, multitouch wall. The exhibit is being built for a major North American aquarium and it will be installed in early summer 2011. We are building out a rig to hold two short-throw HD projectors and four cameras.  A powerful custom-built  PC will be used for tracking and powering the projectors.

Here are some photos of us getting started. Paul Lacey, Chris Steinmetz and I will post updates as we continue to build out the exhibit over the next few months.

Monster Sized PC

A huge aluminum case (25.24″ x 8.66″ x 24.92) is needed to house the EVGA Classified EATX System board.

Here are the rest of the specs for the system:

Intel Core i7 Extreme Edition 975 3.33 GHz
nVidia Quadro FX 5800 4GB GDDR3
12GB Corsair Dominator DDR3
2x 300GB 10,000 RPM WD Velociraptor Hard Disk Drives (RAID 1)
920Watt Enermax 85+ Power Supply
3 PCIE Firewire Cards (cameras)
Windows 7 Pro 64bit

We’ll post an update as we begin to build out the projector rig.

Introducing Open Exhibits

open exhibits dashboard designOn September 21st, I announced that we received funding for Open Exhibits from the National Science Foundation.  It is great to be able to announce today, just two months later, that Open Exhibits core software and a new community site are now available at OpenExhibits.org.

We are, by just about any measure, off to a very fast start.  While Open Exhibits is a three-year exhibit software initiative, we know how hard it is to develop a community of practice and we understand that it takes time. Quickly releasing software and developing a site that allows our community to take root is the first step.

On the Open Exhibis site, you’ll find Open Exhibits Core software, which includes support for multitouch gestures within Adobe Flash and Flex. Along with the core, the first open source templates and modules are also available. These templates and modules will allow developers to easily create interactive exhibits. All of this software is free for museums, nonprofits, universities, students, and other educational organizations. (Commercial users of GestureWorks can also use the templates and modules and are encouraged to contribute.)

The Open Exhibits site allows for software downloads and uploads and there is a community blog that any member can contribute to. In addition, the site has personal profiles, tutorials, support, and documentation. New features will be rolled out over the next few weeks.

I would be remiss if I didn’t mention the fantastic team at Ideum that helped put all this together. Chad Person is the Open Exhibits project manager and helped design and oversee the site. Danillo Stern-Sapad is the main site developer (we built the site in Drupal). Erin Rose is a content developer and social media outreach specialist and helped with the tutorials and blog. James “Glass” Cartwright was the CSS master for the site, while James Kassemi helped with database and Javascript implementation. Open Exhibits software developers Matt Valverde and Paul Lacey put together all of the modules and templates. They also worked with Chris Gerber to put Open Exhibits Core together, implementing the new module and gesture support, as well as an extensive set of documentation.

We encourage you to check out Open Exhibits and join us. We are just getting started.

Apple, Not Flash, Might Be In Trouble

As the so-called Apple vs. Adobe war continues, the consensus that Apple is winning out and that Adobe (Flash in particular) is in trouble has begun to crumble. A recent New York Times article, Will Apple’s Culture Hurt the iPhone?, raised some very interesting questions about Apple and the long-term prospects for its closed development environment. They (and we here at Ideum) are wondering:

Can Apple, which insists on tight control of its devices, win in an intensely competitive market against rivals that are openly licensing their software to scores of companies?

Back to the Future
If history is any judge, the long-term prospects might not be so great for Apple facing such intense and wide-spread competition. As the Times article also mentioned . . .

“In the early 1980s, the Macintosh faced an onslaught of competition from an army of PC makers whose products ran Microsoft software. The fight did not end well for Apple.”

I agree. I’ve been an Apple user and enthusiast since the 1980s. Not even counting my family’s Apple II, I’ve owned a dozen Macintosh computers since the release of the Mac Plus back in the 1980s. I’ve seen a lot of highs and lows in the 25 years that I’ve followed Apple.

Besides using history as a guide, my recent move from an iPhone to an Android phone has further convinced me that Apple will likely be a niche player in a market that they now dominate. My HTC EVO with Android 2.2 does most of the things my iPhone did and it does many things better. It also runs Flash.  (Yes, I can actually see the entire Internet now and am glad to have the option.) Apparently, my Android phone purchase was part of a larger trend as Android has now passed both BlackBerry and iOS in recent purchases.

Development: iPhone vs. Android
Our recent experience in developing our first iPhone App and Android “tests” with Flash have further reinforced my belief that even with Apple’s huge lead, in the long-term, it may be in trouble.  The iPhone development environment was challenging. Although ultimately workable (check out our Space Weather Media Viewer app), it was a frustrating process with many seemingly unnecessary bureaucratic hoops that we had to jump through.  And the majority of our frustrations with iOS have to do with publishing.

iPhone development required an official iPhone Development Certificate, iTunes software to connect to, and other restrictions. We had a ten day wait until our application was released in the Apple iTunes store. We needed to make a simple text change to our icon, and are currently in our second ten-day waiting period (and counting) just to make that one change. The application is, by the way, free and public domain, but still the store is the only way (short of jailbreaking) to distribute it.

When we did some test authoring using Flash on the Android platform, we could try out the application by emailing it or installing it via USB. There weren’t development certificates or other restrictions to deal with. We could author in Flash, make some adjustments in the Android SDK, and we were good to go. While we haven’t put anything into the Android market place yet, we’ve heard that the process is simpler (although the grass is always greener). But judging simply by the nature of the authoring environment, it seems that there are alternatives for distribution that simply aren’t available when authoring for iOS.

Going Forward
Many arguments against Flash have to do largely with performance. This is not a real issue on my HTC EVO; Flash performs reasonably well. Perfect, no, but again I’m glad to have it. Battery use is another issue, but lots of activities (wireless, screen brightness, playing audo, etc.) can contribute to reduced battery life.

As mobile processors continue to improve and Adobe (slowly, painfully slowly) improves Flash performance, I think we’ll see more choices for authoring for smart phones and tablets. And Flash will have a role to play; its developer base is just too vast and it’s too versatile a tool for it not to be a major player. Many people thought Flash video was dead back in the mid-2000s when it faced competition from Apple QuickTime, RealMedia, and WindowsMedia. Remember how that turned out?

Certainly HTML 5 could be an authoring solution in the future, but right now there are plenty of questions surrounding it. The W3C themselves said it was “Not Ready for Production Yet.” Also, it may be that in the future you’ll author HTML5 using Adobe Flash.

Going forward, I have a hard time seeing how iOS can continue to dominate. As I mentioned earlier, it is not so much about iOS authoring, but rather how things are published. A byzantine publishing platform that requires Steve’s way (iTunes) or the Highway, coupled with a tightly controlled and proprietary hardware platform, is hardly a progressive model.

If this model didn’t work for Apple back in the 80s, why should it now?

Simple Mobile: Using QR Codes with a Multitouch Table Exhibit

This week we put together a quick test using QR Codes to extend a multitouch exhibit that we developed last year. QR Codes are an easy way to incorporate a mobile exhibit component that allows visitors to view and share more information about exhibit objects or media items. Any user with a smartphone can use a barcode scanning app to scan a QR code, which can then navigate to websites, source materials, teacher guides, commenting; basically, the possibilities are endless. Users can also choose to share the link with friends via social networking sites or email.

We reworked the EM Spectrum multitouch, multiuser exhibit that we developed with Adventure Science Center last year to include QR codes with links to Wikipedia entries for each area of the spectrum. Check out the video below to see the updated EM spectrum exhibit.

This experiment has proved useful enough that we’ve decided to add a QR Code generator to our Open Exhibits software modules. You’ll be able try these for yourself when the redesigned Open Exhibits site launches and the software is released on November 15th!  Open Exhibits core multitouch and multiuser software is free for educational use. All Open Exhibits modules are free for any user and they also work with the commercially available GestureWorks software framework.
