Visual Displays, Reading Rulers and Overlays

A4 Colour Overlays, Full size coloured overlays can be preferable to the smaller, more convenient Reading Rulers in a number of cases. For example where factors of age or disability cause coordination problems, or when both hands are engaged while text and other representations are being followed.

The Duo Reading Ruler is a narrow (app. 1cm) strip for highlighting single lines of text. Broad (app. 2.5cms) strip for scanning ahead in a paragraph and for studying diagrams, tables, columns of figures etc. Text marker (a solid line on the edge of the broad strip) for tracking down a paragraph.
