Augmented Reality




This session (details below) had some interesting ideas for technologies, even if the devices themselves were not yet perfected.

I thought the most intriguing device was a scrolling mobile web enabled PDA. Using this device the user could surf a to a web site (the example used was USA Today). The site however was not scaled to fit the PDA's tiny resolution and viewing area. Instead the site remained a more normal size (like 800 x 600) and by moving the PDA around on a flat surface (table) the user would scroll back and forth, up and down across the web page using the PDA like a window with a portion of the web site showing through. The web site maintained all its functionality (clicking links etc). It was an experience that I would equate with sitting at a table reading a newspaper through a magnifying glass. What you see through the glass as you move it around creates a similar experience as to what would be seen through the PDA as it is moved around across the virtual face of the web site.

Inside-Out Interaction: An Interaction Technique for Dealing With Large Interface Surfaces Such as Web Pages on Small-Screen Displays
An interaction technique for navigating large interface surfaces such as web pages, in which the user manipulates the physical display device rather than the virtual surface itself.

An Autostereoscopic Optical See-Through Display for Augmented Reality
A novel projection-based autostereoscopic optical see-through display that enables minimally intrusive augmented reality. A holographic optical element eliminates the need for the user to wear any equipment.

Wearable Scanning Laser Projector (WSLP) for Augmenting Shared Space
A novel wearable apparatus for augmented reality. The head-mounted projection system uses rapidly scanned lasers to display information directly onto any object using the object as a projection screen.
