This paper proposes the first user-independent inter-keystroke timing attacks on PINs. Our
attack method is based on an inter-keystroke timing dictionary built from a human cognitive …

The availability of software applications has contributed to the increase in user demand,
which has increased the complexity of these applications. This contributed to the adoption of …

Computational modeling has long been one of the traditional pillars of cognitive science.
Unfortunately, the computer models of cognition being developed today have not kept up …

We start by reviewing several logging tools. We then report improvements to a keystroke
logger we have developed for the Mac and PC, Recording User Input (RUI). These …

As software systems evolve, new interface features such as keyboard shortcuts and toolbars
are introduced. While it is common to regression test the new features for functional …

Time is a widely accepted means for evaluation of procedures used in the management and
control of complex, dynamic systems, such as airliners. Time provides a common unit of …

Designers often struggle to create interfaces that are optimal for both younger and older
adults, as they may interact differently with the same interface. Human-performance models …

Many devices are designed to allow skilled users to complete routine tasks quickly, often
within a specified amount of time. Predictive human performance modeling has long been …

As the complexity of human-machine systems grows rapidly, there is an increasing need for
human factors theories and computational methods that can quantitatively model and …

Individual differences in the strategies that control sequential behavior were investigated in
an experiment in which participants memorized sentences and then wrote them by hand, in …
