“…Consider a future device for individual use, which is a sort of mechanized private file and library.…A memex is a device in which an individual stores all his books, records, and communications, and which is mechanized so that it may be consulted with exceeding speed and flexibility.

It is an enlarged intimate supplement to his memory…"

Surprised by results?

Windows Phone 7 has very promising UX!

Google Nexus One disappointed me!I expected UX breakthrough from them…

iPhone did revolution in the past…But it isn’t a killer mobile UX now. S60 5th has good ideas (haptic), but default screen UX isn’t good.

What is Next?

I had a chance to talk with one of Burj Dubai architects, in San Diego in July 2009…about interfaces and interaction technologies
