Adapting an interface requires taking into account both the positive and negative effects that
changes may have on the user. A carelessly picked adaptation may impose high costs to the …

In the relatively recent past, the analysis of keystroke dynamics for biometric recognition
purposes has intrigued researchers, since practical evidences have shown differences in …

We present PizzaText, a circular keyboard layout technique for text entry in virtual reality
(VR) environments that uses the dual thumbsticks of a hand-held game controller. Text entry …

There have been significant advances in simulation models predicting human behavior
across various interactive tasks. One issue remains, however: identifying the parameter …

Traditionally, touchscreen typing has been studied in terms of motor performance. However,
recent research has exposed a decisive role of visual attention being shared between the …

Aalto Interface Metrics (AIM) pools several empirically validated models and metrics of user
perception and attention into an easy-to-use online service for the evaluation of graphical …

This essay addresses a foundational topic in applied sciences with interest in design: how
do theories inform design? Previous work has attributed theory-use to abduction and …

Video games have long been heralded as powerful learning tools. Yet half a century since
the term “serious games” was coined (Abt, 1970), the evidence on whether and when games …

Ability-based optimization is a computational approach for improving interface designs for
users with sensorimotor and cognitive impairments. Designs are created by an optimizer …

We present a computational model of visual search on graphical layouts. It assumes that the
visual system is maximising expected utility when choosing where to fixate next. Three utility …
