I have recently been made aware of a Korean company called NaviSis, and what I see, I like. NaviSis specializes in "ultrasonic wave and infrared ray tablets and electronic pens".

They have several products which allow for some serious interaction for the user and their computer screen via electric pen. For example, the TabletMouse and Navinote allow a user to write or draw on a pad, and have it be translated directly into a computer. Items like the Laptop Pen and EZ-Canvas turn the screen into a drawing board. You can read more about the aforementioned products here.

Companies like NaviSis are showing that people are looking beyond the traditional mouse and keyboard to interface with their computer.
