When orienting attention, inhibition mechanisms prevent the return of attention to previously examined stimuli. This inhibition of the return of attention (IOR) has been shown to be associated additively with location- and object-based representations. That is, when static objects are attended, IOR is associated with both the object and the location cued, and hence IOR is larger than when only ...

Location-based services, navigation applications, emergency services, management of equipment in the field, and other locationdependent services need geographic location information about a Target (such as a user, resource or other entity). There is a need to securely gather and transfer location information for location services, while at the same time protecting the privacy of the individuals...

Within the cultural heritage community, it is increasingly common to distinguish the tasks of identification and addressing the object by using a location-independent Persistent Identifier (PI) such as a URN (Sollins et al., 1994), a DOI (DOI, 2010), or a Handle (Handle, 2010) linked to a URL describing the object location in an institutional repository or a digital long-term preservation syste...

We propose a method for tracking an object from a video sequence of moving background through the use of the proximate distribution densities of the local regions. The discriminating features of the object are extracted from a small neighborhood of the local region containing the tracked object. The object’s location probability is estimated in a Bayesian framework with the prior being the appr...

Locating mobile objects in a worldwide system requires a scalable location service. An object can be a telephone or a notebook computer, but also a software or data object, such as a file or an electronic document. Our service strictly separates an object’s name from the addresses where it can be contacted. This is done by introducing a location-independent object handle. An object’s name is bo...

Location-based services, navigation applications, emergency services, management of equipment in the field, and other location-dependent services need geographic location information about a target (user, resource or other entity). There is a need to securely gather and transfer location information for location services, protecting the privacy of the individuals involved. This document describ...

Object-location memory is particularly fragile and specifically impaired in Alzheimer's disease (AD) patients. Electroencephalogram (EEG) was utilized to objectively measure memory impairment for memory formation correlates of EEG oscillatory activities. We aimed to construct an object-location memory paradigm and explore EEG signs of it. Two groups of 20 probable mild AD patients and 19 health...

The crux of vision is to identify objects and determine their locations in the environment. Although initial visual representations are necessarily retinotopic (eye centered), interaction with the real world requires spatiotopic (absolute) location information. We asked whether higher level human visual cortex-important for stable object recognition and action-contains information about retinot...
