Abstract : The conventional two-dimensional display is only satisfactory for presenting two-variable information. It is desirable to get more variables into a two-dimensional display. Coding the target spots provides a way of doing this. Coding may be done by varying the target spots in color, brightness, size, intermittence, and shape. These may be used in combination. To assess the utility of these codes will require much fundamental research on discriminability, scaling and learning. A display of many targets, each complexly coded, may make a single display completely incomprehensible. Therefore, the problem of interpretability must be studied in the final phase of the work on coding. (Author)
