Description

New display technology in educational settings In learning tasks, visual attention is often considered as important mediator for processes of knowledge acquisition. For example, the spatial separation of semantically related information may impede attention, which in turn may affect learning. In this project we address this important issue by manipulating the attentional demands of various learning conditions. One way of doing so is to attract attention of learners to different parts of complex mechanical devices by manipulating the presentation speed of the animation. Another way to foster attentional processes is to make use of a so-called autostereoscopic display technology, which enables the simultaneous presentation of two related visualizations in an integrated way. Here the learner does not have to split the attention between two separate displays but instead just has to slightly move his head when he wants to switch between the two presentations.
