Multiple Spotlights of Attentional Selection in Human Visual Cortex
Spatially directed attention strongly enhances visual perceptual processing. The metaphor of the "spotlight" has long been used to describe spatial attention; however, there has been considerable debate as to whether spatial attention must be unitary or may be split between discrete regions of space. This question was addressed here through functional MR imaging of human subjects as they perfor...

15 صفحه اولEmergence of visual objects involves multiple stages of spatial selection.
Attention may select objects or perceptual groups as fundamental units. Previous studies with event-related potentials (ERPs) have found that obligatory attention-spreading over spatial regions within stable objects is associated with intermediate feedforward visual processing, as reflected by the posterior N1 component of the ERP at a latency of 140-180 ms. The present study examined object-ba...

This paper exploits wearable computers unique oppor tunity to record and index the visual environment of the user from the rst person perspective We propose to use a hat mounted wearable camera to record what the user sees during the day with a wearable computer This camera can be used to make the computer more contex tually aware of the user and their actions Furthermore the camera can be used...
