Impact of Various Assistance and Operation Types on the Usability of Mobile User Interface Creation

LOCATION: Auditorium 1, TEL, Ernst-Reuter-Platz 7, 20th floor

Date/Time: 20.04.2015, 13:15-14:00

SPEAKER: Matthias Heicke (TU Berlin)


Assistance methods, like automated input correction, are already an important part of today’s software environment. Especially in the mobile context they can be beneficial for a wide variety of users. To research the influence of assistance, a prototype with two input types (Spinning-wheel and Drag’n’Drop) and three levels of assistance (no, little and full) was implemented and surveyed in a user experiment. The results showed a strong influence of the input types as well as of the levels of assistance. While the users preferred full-assistance in active usage they stated to prefer little-assistance at the end of the experiment. The levels of assistance had a larger effect on the less user-friendly input type (Spinning-wheel).
