Connecting the Dots: Simple Text Input in Immersive Environments
Scott Frees, Rami H. Khouri, G. Drew Kessler · 2006
We present a novel text input interface for immersive virtual environments called CTD, or "Connect the Dots". The CTD interface is a small virtual panel containing a grid of dots the user can connect to form alphanumeric characters using a hand held stylus. Coupled with a physical paddle or desk for force feedback, the CTD provides an intuitive text input interface similar to using a pen and paper.
