Study on standard visual acuity curves for better seeing in lighting design

Ideal seeing conditions; the study of the human visual system as a basis for prescribing lighting.

In the Illuminating Engineering Society's pamphlet on the lighting of factories, entitled 'Making Work Lighter,' I it is stated: 'Every-day experience is the only proof we need that much better lighting is necessary for seeing very small than very large objects, and scientific investigation has taught us just how much better it needs to be.' The pamphlet goes on to describe the scope of good li...

Believing is seeing: using mindlessness (mindfully) to improve visual acuity.

These experiments show that vision can be improved by manipulating mind-sets. In Study 1, participants were primed with the mind-set that pilots have excellent vision. Vision improved for participants who experientially became pilots (by flying a realistic flight simulator) compared with control participants (who performed the same task in an ostensibly broken flight simulator). Participants in...

Seeing more is seeing better.

Programming for Artists: A Visual Language for Expressive Lighting Design

Programming is a process of formalizing and codifying knowledge, and, as a result, programming languages are designed for generalists trained in this process of formalization. Artists, whose training focuses on skill and tacit knowledge, are marginalized by existing tools. By designing visual languages that take advantage of an artist’s skills in visual perception and expression, we can allow t...

Resolution Acuity is better than Vernier Acuity

Our impressive sensitivity to vernier offsets as compared to resolution acuity has long inspired vision researchers to study the phenomena in great detail. In this study we use the test-pedestal framework to compare resolution and vernier acuity. In these experiments the test stimulus is the same for both tasks, only the pedestals differ. When thresholds are expressed in common units of test st...
