A linear slide rule is used to decode symbolic data and preferably comprises a plurality of slidably mounted, inter-changeable data fascia plates 3, 4. The data fascia plates 3, 4 may contain symbolic data series, such as I Ching trigrams transcribed from data sources such as circular disks. The data may be embossed, cut or drilled on or into the data fascia plates 3, 4, which may be fabricated from a variety of materials such as plastic, wood or metal. The information contained in the data fascia plates 3, 4 is preferably decoded using a sliding cursor 5 divided into a grid comprising a specific pattern of opaque and transparent grid squares. The data that can be observed through the transparent grid squares of the cursor 5 may be tabulated into groups of data to form computer pixels, which may then be used to generate pictorial information. Mechanical, electrical, pneumatic or computing devices may be used to automate the decoding process. |
