Abstract

Tastatura QWERTY, u slučaju virtualnih tastatura, ima nedostatke koji potječu još od doba pisaćih mašina. No, unatoč tome i dalje je najkorištenija virtualna tastatura na mobilnim napravama, te je prihvaćena kao standardna od većine ljudi.
U ovom radu istražene su metode optimizacije virtualnih tastatura kao i postojeće izvedbe virtualnih tastatura, čiji je razmještaj tipki dobiven koristeći jednu ili više metoda optimizacije.
Algoritam Metropolis, te pripadajuća tastatura ATOMIK, prihvaćen je kao najefikasniji parametar optimizacije za dobivanje optimalnog razmještaja tipki virtualne tastature s ciljem što bržeg unosa teksta.
Na osnovu spomenutog algoritma, izvedena je vlastita virtualna tastatura CBoard (Custom Keyboard) za operativni sustav Android. Ista je eksperimentalno vrednovana u odnosu na uobičajene atribute upotrebljivosti, te je rezultat eksperimentalnog vrednovanja uspoređen s rezultatom dobivenim prediktivnim vrednovanjem.
Nadalje, istražene su ideje za dodatnu optimizaciju sa svrhom postizanja lakšeg učenja nove tastature.

Abstract (english)

QWERTY keyboard as virtual keyboard, has downsides that date from the time of mechanical typewriters. Despite that, it is still the most used virtual keyboard on mobile devices and it is accepted as standard by most of the people.
In this paper, available methods for optimisation of virtual keyboards have been researched, as well as existing virtual keyboards whose key layouts have been obtained through one or more optimisation methods.
Metropolis algorithm, and related ATOMIK keyboard, has been accepted as the best optimisation method for obtaining optimal key layout with goal of maximising speed of text input.
Using the Metropolis algorithm, custom Cboard (Custom Keyboard) has been developed for operating system Android. CBoard was then experimentally tested for usability in regards of usual usability attributes. The results were compared to predictive results of keyboard performance.
Furthermore, additional ideas for keyboard optimisation have been researched with goal of facilitating learning of the new keyboard layout.
