Abstract
Stimulation elicited by a real world field of view is directly connected with the colour information reaching the cornea and the position where this information is received within the retina: different spectral power distribution of light determine different responses. Evaluation of stimulation provided by a given field of view can be performed in a quick but accurate way by measuring spectral irradiance with a spectroradiometer and apply to incoming data an efficiency curve weighting. However, this can be insufficient for an accurate understanding of the origin of a stimulation: the proposed method allow an overall evaluation of the field of view based on basic spectral and luminance measures and a script that processes gathered luminous information. The final aim of this approach and calculation model is to provide further information about the direction of light reaching the retina, providing a qualitative evaluation of the field of view, allowing to know how much stimulation is due to a specific type of surface or is coming from a certain area within the visual field. This approach can have many practical implications, allowing technicians and designers to modify visual fields in order to properly shape the features, of stimulation throughout the day, hence following a field of view-based dynamic design.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
