At the beginning of last week, I had the pleasure of participating in a workshop hosted by the Innovative Learning Center on Digital Storytelling. The workshop was led by two great facilitators from the Center for Digital Storytelling based in Berkeley, California. Daniel Weinshenker, the Director of the Denver Office, and Jessica McCoy, an instructor based at the Berkeley office, did a wonderful job leading the workshop. If you're unfamiliar with Digital Storytelling, take a look at the Center's website. Jessica is also involved with an organization called Stories for Change. Both websites host several amazing examples of digital stories.

Just read a nice article on New Scientist about work by Microsoft and Mitsubishi on a novel approach to handling the occlusion problem and the "fat finger" problem of current multi-touch interfaces. There's also a video of a prototype of the LucidTouch device.

The current prototype device uses a camera on a boom focused on the hands on the back of the device. An overlay shadow is superimposed over the image showing the location of the hands without occluding the display. Active finger touch points are shown and a very intuitive method for showing the hand-off of selected items between fingers is also used. It's a nice glimpse of what's ahead in the multi-touch arena.

In preparing for a class on PowerPoint 2007, I ran across a little tutorial on YouTube outlining how to embed a YouTube video in a PowerPoint 2007 presentation. Unfortunately, the audio in the tutorial is really poor, so I thought I'd list the steps here and create a Captivate animation for it as well.

To embed a YouTube video in PowerPoint 2007 follow these simple steps:

1. First turn on the Developer Tab on the Ribbon by clicking on the Microsoft logo at the top left of the window and selecting PowerPoint Options all the way at the bottom of the menu. Next put a check next to the unchecked item to show the Developer Tab
2. Go to YouTube and select a video to embed
3. Copy the URL
4. On the Developer menu choose "More Controls"
5. Select Shockwave Flash Object
6. Click and drag on the PowerPoint slide to add the Flash object
7. Right Click the object placeholder and select properties
8. Set the Movie property to the URL you copied
9. In the URL delete "watch?" and change the "=" sign to a ⁄
10. Adjust the options for Looping or AutoPlay if desired

Make sure to test the presentation and keep in mind that the video is streaming from YouTube, so an Internet connection is required at the time of presentation.

In an earlier post, I wrote about Microsoft's Surface technology and work done at NYU on multi-touch display technology. Peter Hutterer at the University of South Australia's Wearable Computer Lab has just demoed a new version of his MPX, Multi-Pointer X Server under Linux. There's an article on his blog and a video of his multi-touch extension of MPX under Ubuntu. Here are the hardware details. Now I just need to get my hands on a compatible touch screen and try this out

Wired ran an article in the latest issue about a new website that takes the idea of user created video to the next level with a focus on experimental methodology in the sciences. The Journal of Visualized Experiments offers howtos on hardcore experimental methods. These methods have been bound up in tacit knowledge which is extremely difficult to extract from the brains of seasoned researchers. Now with a little work and a community of inquiry spirit, these bits of specialized expertise can be easily accessed as needed. This kind of site really brings to the fore the fact that video has reached the level that desktop publishing reached in the last decade. What's next you might ask? Desktop fabrication. Work has already begun on DIY open source rapid prototypers.

In preparing for our recent Faculty Symposium on Digital Trends: The Mobile Classroom, I took a video lecture that I had in AVI (Xvid encoded) format and converted it into several formats to play on portable devices to demo in the presentation. Getting the video on my iPod Video and Playstation Portable was straightforward and familiar. But the phone was new and even though I knew it could be done, it took some experimentation and an inexpensive hardware purchase.

Microsoft recently hit the news circuit with an announcement of a new class of devices that feature touchscreen interfaces that allow for multiple simultaneous touchpoints. The project is called Microsoft Surface. Here's the ZDNet story on it. And here's a nice video of the system.

I have been following the development of multi-touch display technology for a few years. I ran into the technology at SIGGRAPH a few years ago and each year have seen major advances. The project was based at NYU and was recently spun off into a private company called Perceptive Pixel. The NYU software ran on Linux (I seem to remember).

I wonder if they will be able to get their systems to consumers at a reasonable price sooner than Microsoft. Either way, I'm really looking forward to getting my hands on one of these things.

So, I know some of my readers have used my original DVD ripping and encoding guide to get setup with the right software. But some of the recommendations are stale. At the very least I wanted to recommend a product to take the place of DVD Decrypter which has been abandoned by its creators under legal threats from the MPAA and their minions.

I have been using an inexpensive tool from Slysoft to help with copying DVDs. AnyDVD is a lightweight driver that removes CSS, Macrovision, and Region Codes from DVDs making them directly accessible for conversion using any encoding utility such as Nero Recode 2, 1ClickDVDCopy, and others. For $30 it is well worth the price. The application is updated frequently to keep up with new encryption/copy protection schemes used by movie studios who want to tell you where and when you can watch a DVD you have purchased. Highly recommended.
