| Abstract |
The major categories of variables included in the perception of the visual environment are identified and classified with respect to their relation in developing lighting criteria and standards: acceptance by the office user, visual task performance, non-visual environmental influences (temperature, noise, colour, psychological factors), visual process, sensory process, perceptual process, visibility, threshold visibility. The implications for standardisation are considered: Recommended light levels for commercial tasks should be based on laboratory studies of suprathreshold visibility. It is stressed that the setting of higher light levels for an infrequently encountered difficult task can lead to visibility losses for other more frequently encountered tasks. |
