Based on data from SiteMeter, there are a number of my readers who are searching for information about touch screen interaction design and multi-touch systems. A great resource for anyone interested in these topics is Bill Buxton's website, "Multi-Touch Systems that I have Known and Loved".
Bill provides a good overview of the various flavors of multi-touch interaction and interfaces, along with a an annotated chronology of multi-touch and related technologies, starting before 1982. The chronology includes some interesting pictures.
Bill Buxton works for Microsoft Research. The following information is from his bio:
"Bill Buxton is a designer and a researcher concerned with human aspects of technology. His work reflects a particular interest in the use of technology to support creative activities such as design, film making and music. Buxton's research specialties include technologies, techniques and theories of input to computers, technology mediated human-human collaboration, and ubiquitous computing."

About Displays: Content Interface- Touch Interaction on a Panasonic Display
Here is a video-clip of a demo from Content Interface using a large touch-enabled Panasonic display.
About Displays
From time-to-time I will share information about displays under the heading "About Displays"
Why? When I set out to learn more about display hardware and related technologies that support interactive multimedia applications, I quickly discovered that things are changing - fast. Some of the technology is complex.
I will post a list of research articles and related information soon. I know that my list is missing some pieces, as it is difficult to keep up with important changes. For this reason, I'm asking my readers to help me out by posting a comment about display-related information to share with others when you come across something interesting and useful.
Here is an example of something worth sharing:
Dolby Acquires BrightSide
"The DR37-P is a spectacular breakthrough in display technology. It uses an array of individually modulated LED backlights to provide 10 times the brightness and 100 times the contrast of existing television and computer monitors. The Extreme Dynamic Range display delivers more vibrant images, enabling you to see information onscreen in vivid detail."
"In an HDR-enabled display, the backlight consists of an array of ultrahigh-brightness white or tricolor light-emitting diodes (LEDs). Each LED can be controlled individually—faster than video refresh rates. The lower-resolution LED image is then projected through a standard LCD panel, which displays a high-resolution version of the image, resulting in a vibrant display."
A display with HDR technology might be something to consider for use with people with visual impairments, which are more commen among the elderly.
Links to whitepapers, screen shots, and interactive demos are welcome!

Mobile Projection from a Cell Phone or PDA!
Microvision and other companies have developed projector that enable cell phones and PDA's to display pictures and videos. With the PicoP, the images work on flat as well as curved surfaces. It looks like it would be a great visual communication and collaboration tool.
The PicoP
If you have had the opportunity to use a mobile projector, please let me know!

Visual Learning Lab Supports Effective Teaching and Learning
It seems that the UK is often on the cutting edge of using multimedia technology in education.
Here is a quote from the Visual Learning Lab website, at the University of Nottingham about ways the Humanities department is using visual learning technologies:
‘Showing Seeing Centre’ & ‘Visual Analysis Lab’
"Archaeology and Classics are both highly visual disciplines. In order to further develop the use of visual in teaching and learning, the VLL supports the creation of two new facilities, the Showing Seeing Centre and the Visual Analysis Lab."
"The Showing Seeing Centre will provide a context for students to work with visual resources using 3D-enabled computers for access to virtual reconstructions of archaeological sites and ancient civilizations, e.g. in gaming environments. Students will also have access to a range of equipment for digitzing and analysing visual material and for producing presentations and portfolio material. The equipment provided by the VLL consists of a wall-mounted LCD-screen, 4 high-spec laptops, a
high-spec A4-scanner, colour laser printer and a Playstation."
"The Visual Analysis Lab will provide facilities for teaching and learning in relation to the identification of archaeological remains (such as plant materials, animal bones and ceramics). The equipment provided by the VLL consists of two high- quality microscopes linked to digital cameras, a laptop and a data projector."
A 2007 report (pdf) from the University of Nottingham's Visual Learning Lab reviews of how visual learning technology will be used by departments such as pharmacy, veterinary medicine, medical sciences, modern language and cultures, biosciences, humanities, fildm and telvision studies, learning sciences, and computer sciences.

FutureLab, of the UK, hosted a debate of the educational merits of interactive whiteboards, one of the technologies used to support visual and interactive multimedia teaching and learning. With the rush to adopt this technology for primary and secondary students, the participants pointed out that in order for teaching and learning to be effective, appropriate teacher training must take place.
If you have been following the Interactive Multimedia Technology or the Tech Psych blogs, you know that I'd like to see something like Microsoft's Surface in classrooms. Touch screen displays, such as the NextWindow Human Touch, appear to be more effective if they aren't dependent on a projector.

HP TouchSmart PC - an interactive touch screen for the home- and classroom?
I think this PC has possibilities for use in libraries, school media centers, and in classrooms.
This is a short video clip about the HP TouchSmart PC, a medium-sized touch-screen display that runs on Window's Vista. From what I understand, it uses technology from NextWindow.
If you use TouchSmart PC or something similar, or if you develop applications for the TouchSmart or other interactive touch applications, let me know what you think!
