Visual Light Zones

Visiting the red-light zones with Claudio

Received: 2 August 2005 Revised: 27 September 2005 Accepted: 28 September 2005 Introduction Shortly after Claudio’s permanent appointment at the LSE, he joined me in teaching the advanced MSc option ‘Interpretations of Information’. I had previously co-taught this course with Lucas Introna who had recently moved to Lancaster University. Both Lucas and Claudio shared a love of the work of Martin...

The visual light field.

Human observers are sensitive to the '(physical) light field' in the sense that they have expectations of how a given object would appear if it were introduced in the scene in front of them at some arbitrary location. Thus the 'visual light field' is defined even in the 'empty space' between objects. In that sense the light field is akin to visual space considered as a 'container'. The visual l...

Distinct Acute Zones for Visual Stimuli in Different Visual Tasks in Drosophila

The fruit fly Drosophila melanogaster has a sophisticated visual system and exhibits complex visual behaviors. Visual responses, vision processing and higher cognitive processes in Drosophila have been studied extensively. However, little is known about whether the retinal location of visual stimuli can affect fruit fly performance in various visual tasks. We tested the response of wild-type Be...

Modulation of fluorescent light: flicker rate and light source effects on visual performance and visual comfort

Projected light displays using visual feedback

A system of coordinated projectors and cameras enables the creation of projected light displays that are robust to environmental disturbances. This paper describes approaches for tackling both geometric and photometric aspects of the problem: (1) the projected image remains stable even when the system components (projector, camera or screen) are moved; (2) the display automatically removes shad...
