Description

To analyse the human visual perception process by backward masking, thousands of TS's and MS's must be exposed even in an experiment. If a mechanical tachistoscope should be used, labors for making such stimuli, for changing them at each exposure and for arranging data of the S's reaction would be exceedingly great. In order to save the lavors, a computer-controlled visual masking system is designed. The computer generates the TS and MS, exposes them on the CRT and collects the S's reaction. A command language named OLM-1 is used to describe forms of TS's and MS's and other parameters of backward masking. Using this system one thousand TS's can be exposed within an hour or so.
