Abstract

Korištenje virtualne tipkovnice pri interakciji s mobilnim napravama sa zaslonom osjetljivim na dodir još uvijek je najrašireniji način unosa teksta. Unos teksta na virtualnim tipkovnicama međutim pokazuje nedostatke u pogledu br- zine unosa teksta i iznosa pogrešaka. Jedna od mogućih tehnika za otklanjanje navedenih nedostataka zasniva se na promjeni dodjele znakova na tipkama tipkovnice standardnog QWERTY razmještaja. U radu je oblikovana tipkovnica s Colemak razmještajem znakova koja je prilagođena unosu hrvatskog teksta, tako da je raspored znakova usklađen s učestalošću pojave bigrama u hrvatskome jeziku. Uspoređena je njezina upotrebljivost usporedbom sa standardnom tip- kovnicom QWERTY na istoj mobilnoj napravi. Vrednovanje je provedeno za različite stavove korisnika i veličine zaslona mobilnih naprava. Prilikom vrednovanja koristi se primjereni standardni skup fraza za eksperimente unosa teksta. Radu su priloženi izvorni programski kodovi i dokumentacija provedenog vred- novanja. Usporedba QWERTY i Colemak tipkovnice su temeljini na usporedbi brzine pisanja i točnosti pisanja različitih fraza.

Abstract (english)

Using a virtual keyboard when interacting with mobile devices with touchscreen is still the most widespread way of text input. Text input on virtual keyboards however, shows shortcomings in terms of text input and error rates. One of the possible techniques for removing these shortcomings is to change the character assignment on the keyboard keys of the standard QWERTY layout. In this work, a keyboard with Colemak character set is adjusted, which is adapted to the input of the Croatian text, so that the arrangement of characters is in accordance with the frequency of the phenomenon of bigrams in the Croatian language. Its usability is compared by comparing it with the standard QWERTY type on the same mobile device. Evaluation was performed for different user views and screen sizes of mobile devices. When evaluating, an appropriate standard phrase set for text input experiments is used. The original program codes and documentation of the conducted evaluation were attached to the paper. Comparison of the QWERTY and Colemak keyboards is based on a comparison of the speed of writing and the accuracy of writing different phrases.
