In what ways does user experience design improve printed educational materials?

We report on a series of four studies that investigated how user experience design (UXD) can improve printed educational materials (PEMs). We examined the perceived usability of an existing PEM for breast cancer screening and observed the usability problems associated with it (Study 1). We then compared a breast cancer screening PEM created by user experience designers with two other breast cancer screening PEMS, finding that the PEM based on UXD had higher perceived usability, and lower mentions of usability problems, than the other two PEMs (Study 2).

Longitudinal analysis of sustained performance on gamified cognitive assessment tasks.

Serious games aim to provide cognitive assessments that are more enjoyable and easier to self-administer, potentially leading to more frequent assessments. We carried out two studies examining the relationship between game-playing enjoyment, game difficulty, and cognitive (game) performance. In the first study, 16 participants played three serious games once a week over four weeks as part of an undergraduate course, but with relatively minor motivation in terms of course credits.

Comparing immersiveness and perceptibility of spherical and curved displays.

Curved displays are believed to create a feeling of immersiveness similar to virtual reality. However systematic studies are needed to demonstrate that this is, in fact, true and under what conditions. In an experimental study 24 participants compared five different displays (concave, convex, hemisphere, sphere and a flat display) in terms of their immersiveness and perceptibility, and they also rated their overall preferences.

Developing and testing a human-based gesture vocabulary for tabletop systems.

Objective: The goal was to study the natural and intuitive use of surface gestures for the development of a tabletop system. Furthermore, the effect of expertise on choice of gestures was examined.

Background: It is still not well understood what kinds of gestures novice users choose when they interact with gesture recognition systems.
