Abstract

The small touch screens of smartphones place new demands on text input methods. One popular method is to use different software that allows users to type words by swiping their finger across the screen.

Different implementations of algorithms for translating sweeping gestures into words were compared in this report. These were also compared with the market-leading solution SlideIT. With relatively simple means a combination of algorithms, whose performance is comparable to SlideIT, was successfully implemented.
