MODERN GREEK LAGUAGE FREQUENCY COUNTS FOR TEXT ENTRY DEVICES
Journal Title: TEHNOMUS - Year 2011, Vol 18, Issue 1
Abstract
In this paper we present and analyze tabulated case-sensitive single letter, digram and trigram frequency counts from a 450 Kword modern Greek corpus. Special characters, such as space, comma, paragraph change and full stop, used for text input, are also included. Data analysis revealed moderate correlation between English and Greek frequency counts, justifying a different approach when studying Greek keyboards. A keystroke-level model using the digram frequency data and applying Fitts’ law was employed to predict entry speed rates for Qwerty, Fitaly, and Telephone virtual keyboards, both in English and Greek layouts. The results of this paper could be used when designing new software or hardware keyboard layouts and in order to improve their efficiency and text entry speed.
