Abstract
Teletext is difficult to read, partly because of the letter fonts employed. Present
fonts are contained in a matrix of 6 (horizontal) x 10 (vertical) elements. Research
on matrix characters of optimum legibility started in 1969 at IPO. Criteria
resulting from this research have now been used to design alphanumeric characters
in a matrix of 12 x 10 elements for future use in Teletext. Several versions of
each character were designed and their legibility tested in recognition experiments.
The legibility of the best new version for each letter was compared with and
shown to be greater than that of the presently used version.
