Investigating Small Device Users' Input Errors under Standing & Walking Conditions - RIAM Technical Report
Tianyi Chen, Yeliz Yeşilada, Simon Harper · 2009
This report presents a user study that investigates small device users' typing and pointing errors under standing and walking conditions. The aim of the study is to find out whether typing and pointing errors identified with small device users under sitting condition still exist when the users are mobile, and whether the error rates will increase in magnitude. The study is designed based on a field study of real world small device users, so that the settings and tasks are close to real-life scenarios. Results of the study show that small device users have more typing and pointing errors when they are walking, and the magnitude of error rates are close to, in some cases higher than, that of motor-impaired desktop users.
