Designers trying to build intuitive interaction need to identify screen elements that (potentially) distract users from reaching their goals. The analysis of cursor movements has been proposed as a scalable and low-cost approach to analyze user distraction. Previous research, however, was mainly focused on finding gaze-analogous variables in cursor tracking data, e.g. cursor dwell times as an analogy to gaze fixations. We propose an approach that uses the shape of the cursor trajectories as an alternative means to estimate and locate user distraction. We present a study that shows the feasibility of the approach and we outline further work needed to use cursor trajectories as a means to automatically measure and identify distracting screen elements.

Mixing Languages? Image Schema Inspired Designs for Rural Africa

Diana Löffler, Klara Lindner & Jörn Hurtienne


The concept of image-schematic metaphors, basic subconscious structures of the human mind, has been used by many researchers for conveying abstract information in user interfaces. Since they can be conveniently derived from the users’ language, an open question is how metaphors differ between languages and, consequently, how to design for multilingual user groups. We explored this issue while designing capacity building tools for the estimation of energy consumption in rural Africa. We found that the majority of image-schematic metaphors are equivalent in Swahili and English and that metaphors deviating in one language complemented rather than contradicted the other metaphors.
