Mental rotation is the capacity to predict the orientation of an object or the layout of a scene after a change in viewpoint. Previous studies have shown that the cognitive cost of mental rotations is reduced when the viewpoint change results from the observer’s motion rather than the object or spatial layout’s rotation. The classical interpretation for these findings involves the use of automa...

The purpose of this research is to demonstrate the influence that a water dome has on a person. The following approach was used for this study: ( I ) A water display was used as a projection screen; ( 2 ) The illusion of being under water was created; and (3) Experiments with water domes of various sizes were carried out. Water display is a head mounted type water membrane. When the display is ...

Miniaturization in projection technology makes it possible to integrate projectors into mobile devices like tablets, PDAs, or mobile phones. This offers new capabilities for input and output, which are seen as promising possibilities to overcome the limited screen size of mobile devices. However, it is still unclear, how projection will be used in combination with the traditional mobile device’...

This study investigated how display parameters influence humans’ ability to control simulated egorotations from optic flow. The literature on visual turn perception reports contradictory data, which might be partly due to the different display devices used in these studies. In this study, we aimed at disentangling the influence of display devices, screen curvature, and field of view (FOV) on th...

In Virtual Reality, considerable systematic spatial orientation problems frequently occur that do not happen in comparable real-world situations. This study investigated possible origins of these problems by examining the influence of visual field of view (FOV) and type of display device (head-mounted display (HMD) vs. projection screens) on basic human spatial orientation behavior. In Experime...
