System and method of measuring line height, font size and international automatic font

摘要

"INTERNATIONAL AUTOMATIC LINE HEIGHT, SIZE AND SOURCE MEASUREMENT METHOD AND METHOD". A system and method for automatically determining font characteristics suitable for different presentation media and readability parameters in any language is described. One method includes determining source characteristics by receiving data including a source identifier and a language identifier, producing a type representative line in the identified language and with the identified source, measuring characteristics of the type representative line. , and the normalization of measurements in a plurality of sources and a plurality of languages. In one embodiment, an international translator is used to receive data including the source identifier and the language identifier, and the received data may include text in a language. Normalization refers to portion widths of the text called a "black river", which is used to identify graphed measured characteristics to determine an average gray tone perpendicular to a reading direction. The medium gray tone allows comparisons with the pluralities of sources and languages. A system and method determine an optimal font size for readability. One method determines font characteristics by determining a character density for the font and multiplying the character density by a sharper focusable area of the display medium. The method further includes varying the character density by a range in a number of clusters per fix to determine a maximum font size and a minimum font size. In one embodiment, character density is a ratio of a number of groupings per eme at the source to a number of visible groupings at a predetermined foveal angle. The predetermined foveal angle may be a field of view for the sharpest focus of an eye or a reader-specific foveal angle that reflects the reader's visual acuity, taking into account macular degeneration, impaired vision, sharpness of vision, vision. in tunnel, eye disease, myopia, hyperopia, dyslexia and astigmatism. A computer-readable system, method and medium automatically determines a suitable line height for different presentation media and different readability parameters in any language. One embodiment is directed to a method for determining a line height for a text stream, and includes determining a value representing a number of groupings per eme in the text stream and scaling the base value line height by means of. an exponential function. Another embodiment is directed to a computer system with a data structure configured to hold a plurality of elements defining source characteristics and a module attached to the data structure, the module dynamically adjusts the line height as visualization changes by using font characteristics and applying an exponential function to an average width of a grouping with font characteristics.
