Interfacing technologies
Respective significance of Fitaly, Tegic T9, Octave methods of keyboards vis-à-vis traditional QWERTY layout based keyboards / keypads, in the context of mobile handheld devices:
§Fitaly
•Merit / Significance:
Speeds up input of text, letters selected as per likely occurrence frequencies and ensuring minimization of inter-letter travel distance (to no more than 2 positions), supports 220 ANSI/ISO Latin- 1 character set, supports accents, available in on-screen as well as mechanical forms
•Demerit:
Specific to English language‟s estimated usage patterns, needs to be practiced for a while before use, needs to learn „sliding‟ for accents‟ use etc.
§Tegic T9:
•Merit / Significance:
Requires lesser number of keystrokes for textual input due to support for predictive text by combining use of dictionary and linguistic rules‟ embedding, resolution of word-ambiguity is supported through prompts, available in on-screen as well as mechanical forms
•Demerit:
Requires sizeable software support and computing resources (instruction cycles and memory)
§Octave:
•Merit / Significance:
Commands available to support multiple language dictionaries, available in on-screen as well as mechanical forms although second form is more popular, gesture-based iconic support for certain insertions, word-recognition supported by dictionary, ability to resolve stroke-ambiguity with the help of dictionary
•Demerit:
Requires sizeable software support and computing resources (instruction cycles and memory)
