Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
201 words
A focal scanning aid comprising: a set of first, second and third mats, each of said mats being of sufficient size to cover at least a portion of a printed page, each of said mats being of substantially rectangular shape and having a substantially black matte surface thereon; first, second and third rectangular apertures respectively in said first, second and third mats, said first, second and third apertures each having substantially the same width which is sufficient to expose a full column width of printed material; said first aperture in said first mat being of such height that an unskilled reader can scan three lines of printed material exposed therethrough in a single scan pass, said second aperture in said second mat having a greater height so that a more skilled reader can scan six lines of printed material exposed therethrough in a single pass, and said third aperture in said third mat being of greater height than said second aperture and being of such height that only a reader of near maximum reading skills can scan printed material exposed therethrough in a single scan pass so that said focal scanning aid progressively trains readers to scan larger quantities of material.
