Qualitative Motion Representation in Egocentric and Allocentric Frames of Reference
1999In qualitative motion representation, frames of reference play an important role as well in measuring of the motion data as in representation and application of algorithms. This paper discusses motion representation in egocentric and allocentric frames of reference and begins with some general considerations on motion representation through qualitative

Egocentric and allocentric frames of reference (FoR) can both be used in navigation aids, but each has benefits and drawbacks. Incorporating both FoR could be beneficial for offsetting the drawbacks of each viewpoint, but research on the timesharing ability of these FoR is lacking.

AbstractRepresentations of space in mind are crucial for navigation, facilitating processes such as remembering landmark locations, understanding spatial relationships between objects, and integrating routes. A significant problem, however, is the lack of consensus on how these representations are encoded and stored in memory.

We report two experiments on the relationship between allocentric/egocentric frames of reference and categorical/coordinate spatial relations. Jager and Postma (2003) suggest two theoretical possibilities about their relationship: categorical judgements are better when combined with an allocentric reference frame and coordinate judgements with an ...

There is evidence that early deprivation of vision prompts the use of body-based, egocentric spatial representations in congenitally blind individuals, whereas previous visual experience favors the use of object-based, allocentric representations (e.g. Pasqualotto A, Spiller MJ, Jansari AS, Proulx MJ.

Human EEG Correlates of Spatial Navigation within Egocentric and Allocentric Reference Frames
2010We investigated the impact of path complexity on brain dynamics of subjects who preferentially use an egocentric (Turners) or an allocentric (Nonturners) reference frame during spatial navigation. Participants indicated a return bearing direction ('point-to-origin') following visual presentation of virtual tunnel passages, varying with respect to the ...

The EEG Correlates of the Allocentric and the Egocentric Spatial Reference Frames Processing
2009In the paper we describe current results of our ongoing research, concerning the navigation in the virtual tunnel task and its EEG correlates. We searched for the features in the EEG signal to discriminate the employment of the allocentric and the egocentric reference frames.

Different strategies in spatial navigation during passages through computer-simulated tunnels were investigated by means of EEG source reconstruction. The tunnels consisted of straight and curved segments and provided only visual flow, but no landmark, information.

Neural correlates of spatial navigation within egocentric and allocentric frames of reference
2023Human activity takes place in space and people need a mental representation of what is “actual” in the physical world to effectively navigate it. The cognitive map is the term we use to describe these representations. Mentally comparing the distances between a reference and a target location is a process that requires the recall of that information off

Spatial memory: the role of egocentric and allocentric frames of reference
2011A fundamental requirement of everyday life is that of encoding and remembering successfully the locations of objects, landmarks or buildings in space. This function is achieved by structuring spatial information in systems of coordinates. There are many ways to classify spatial reference systems (Paillard, 1991), but a useful one, for the purposes of ...
