Pierce, Jeffrey S., Audia, Steve, Burnette, Tommy, Christiansen, Kevin, Cosgrove, Dennis, Conway, Matthew, Hinckley, Ken, Monkaitis, Kristen, Patten, James, Shochet, Joe, Staack, David, Stearns, Brian, Sturgill, Chris, Williams, George and Pausch, Randy (1997): Alice: Easy to Use Interactive 3D Graphics. In: Robertson, George G. and Schmandt, Chris (eds.) Proceedings of the 10th annual ACM symposium on User interface software and technology October 14 - 17, 1997, Banff, Alberta, Canada. pp. 77-78.

Alice is a rapid prototyping system used to create three dimensional graphics simulations like those seen in virtual reality applications. Alice uses an interpreted language called Python as its scripting language to implement user actions. This interactive development environment allows users to explore many more design options than is possible in a compiled language environment. The alpha version of Alice for Windows 95 is available for free over the internet, with the beta release scheduled for August.

Viega, John, Conway, Matthew, Williams, George and Pausch, Randy (1996): 3D Magic Lenses. In: Kurlander, David, Brown, Marc and Rao, Ramana (eds.) Proceedings of the 9th annual ACM symposium on User interface software and technology November 06 - 08, 1996, Seattle, Washington, United States. pp. 51-58.

This work extends the metaphor of a see-through interface embodied in Magic Lenses to 3D environments. We present two new see-through visualization techniques: flat lenses in 3D and volumetric lenses. We discuss implementation concerns for platforms that have programmer accessible hardware clipping planes and show several examples of each visualization technique. We also examine composition of multiple lenses in 3D environments, which strengthens the flat lens metaphor, but may have no meaningful semantics in the case of volumetric lenses.

Leggett, John, Williams, George, Usnick, Mark and Longnecker, Mike (1991): Dynamic Identity Verification via Keystroke Characteristics. In International Journal of Man-Machine Studies, 35 (6) pp. 859-870.

The implementation of safeguards for computer security is based on the ability to verify the identity of authorized computer systems users accurately. The most common form of identify verification in use today is the password, but passwords have many poor traits as an access control mechanism. To overcome the many disadvantages of simple password protection, we are proposing the use of the physiological characteristics of keyboard input as a method for verifying user identity. After an overview of the problem and summary of previous efforts, a research study is described which was conducted to determine the possibility of using keystroke characteristics as a means of dynamic identity verification. Unlike static identity verification systems in use today, a verifier based on dynamic keystroke characteristics allows continuous identity verification in real-time throughout the work session. Study results indicate significant promise in the temporal personnel identification problem.
