Microsoft showed off its proof-of-concept technology application at the Consumer Electronics Show in Las Vegas for 2009. Towards the end of the pre-keynote show, Microsoft demonstrated a concept that involved objects, the Microsoft Surface Computing table, a tablet, digital e-ink display, and a Windows Mobile phone where users can display things from their devices or objects to the table. While that concept had been shown off before, Microsoft made a quick reference to possibly using e-paper technology to display information from your phone.

Electronic paper, which uses electronic ink technology, can be found on popular e-book readers, such as the Amazon Kindle. The concept is that the flexible electronic paper–less than 1 mm thick–can be used as a display for your phone. This means that users can see on an 8.5″ X 11″ paper of what would normally be shown on a 2.8″ display on their phone, like the Touch Pro.

The paper and ink technology used by Microsoft Research Lab as part of the pre-keynote on Wednesday evening was in color, unlike current commercial applications that are in black and white.

The concept would be interesting considering Microsoft’s push for cloud based computing, social networks, and collaboration. Also, since e-ink technology uses little power as like paper it is not backlit, the display wouldn’t be constrained by heavy batteries. Its flexible nature means you can roll it up in a bag, take it with you, and “project” your ideas onto a larger medium to share with others.

Unfortunately, Microsoft’s CES presentation didn’t focus much on Windows Mobile. More details of the CES can be found here at pocketnow. Stay tuned for coverage of the latest product announcements on mobile technology.
