Tiivistelmä
Mobile phone technology is advancing rapidly. Text entry on mobile devices is essential as more and more people are using mobile phones for the purpose of writing text messages. The need to make mobile devices as easy to use and as efficient as possible is more acute than ever. New methods of interaction are proposed but the old ones still stay as long as they provide users with some comfort and benefit which others lack.

I conducted an experiment to compare the two well-known, and till recently, most widely used text entry methods for mobile phones, the multitap and T9. Sixteen participants in two groups, experienced and novice, transcribed phrases, and the speed and error rate were measured.

Statistically significant effects of text entry method, experience, and their interaction were found for text entry rate. T9 users were faster than multitap users and experienced users faster than novice. No statistically significant effects were found for error rate. In comparison to earlier dataon the performance of the multitap and T9, novice and experienced users of multitap and T9 performed better with overall 10.67 wpm vs 7.95 wpm for multitap group and 18.39 wpm vs 14.72 wpm for T9 group.
