The graphical user interface (GUI) has become the prime means for interacting with
computing systems. It leverages human perceptual and motor capabilities for elementary …

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 …

How do people interact with computers? This fundamental question was asked by Card,
Moran, and Newell in 1983 with a proposition to frame it as a question about human …

Users may face challenges while designing graphical user interfaces, due to a lack of
relevant experience and guidance. This paper aims to investigate the issues users face …

We present TangibleGrid, a novel device that allows blind users to understand and design
the layout of a web page with real-time tangible feedback. We conducted semi-structured …

Establishing the best layout configuration for software-generated interfaces and control
panels is a complex problem when they include many controls and indicators. Several …

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 …

We present a novel simulation model of point-and-click behaviour that is applicable both
when a target is stationary or moving. To enable more realistic simulation than existing …

Desktop notifications should be noticeable but are also subject to a number of design
choices, eg concerning their size, placement, or opacity. It is currently unknown, however …

In domains where users are exposed to large variations in visuo-spatial features among
designs, they often spend excess time searching for common elements (features) on an …
