Zusammenfassung: | In contrast with earlier research showing Lansdell numerals superior in legibility to conventional number shapes during brief exposure of single digits, the present study found that Lansdell numerals are read at least 15% more slowly than Mackworth or Elite numbers when groups of five symbols are scanned for a target digit, and are read 34% more slowly when the five digits in each group must be added. This lower readability indicates that Lansdell numerals should not be used in situations requiring interpretation of displayed numbers, i.e., should not be used for most display applications. |
