Presenting waypoint navigation on a visual display is not suited for all situations. The present experiments investigate if it is feasible to present the navigation information on a tactile display. Important design issue of the display is how direction and distance information must be coded. Important usability issues are the resolution of the display and(More)
The introduction of virtual reality technology in the field of human perception and behaviour research has spawned many new research initiatives. The paper outlines the motivations of researchers in this field to start using virtual environments for their studies by presenting two such studies conducted in our laboratory. First, we discuss how we are(More)
OBJECTIVE We investigated the effectiveness of a tactile torso display as a countermeasure to spatial disorientation (SD) and compared inside-out and outside-in codings. BACKGROUND SD is a serious threat to military as well as civilian pilots and aircraft. Considerable effort has been put into SD countermeasures such as training programs and advanced(More)
The literature often suggests that proprioceptive and especially vestibular cues are required for navigation and spatial orientation tasks involving rotations of the observer. To test this notion, we conducted a set of experiments in virtual environments in which only visual cues were provided. Participants had to execute turns, reproduce distances, or(More)
This paper describes two aspects of the application of tactile information presentation in the cockpit. The first half of the paper discusses why the tactile channel might be used instead of, or in addition to, the more common visual and auditory channels. It lists several categories of information used in cockpits and explores their appropriateness for(More)
Virtual reality is used as a novel tool for behavioral experiments on humans. Two e n vironments, Hexatown and Virtual T ubingen, are presented. Experiments on cognitive maps carried out in the Hexa-town environment are reported in this paper. Results indicate that subjects are able to acquire connguration knowledge of the virtual town even in the absence(More)
This paper describes an application of VRML-based multimedia to the domain of spatial cognition experiments. Typically, such experiments involve human subjects that are presented with graphi-cal stimuli in a laboratory setup. Larger numbers of subjects and stimuli give more weight to the outcomes of the experiment, but in practice the number of subjects is(More)
