Gavin Lew (User Centric), Leslie McFarlin (User Centric), and Thomas Green (User Centric) will give a presentation on text-entry user experience on the iPhone at the 52nd Annual Meeting of the Human Factors and Ergonomics Society (HFES). Sixty volunteers participated in a within groups study aimed at evaluating the text entry system on the iPhone. All participants completed multiple structured text entry tasks on the iPhone's soft keyboard and two hard-key mobile phone keypads - QWERTY and numeric. Time to message completion and the number of errors per message were collected to identify potential differences in performance between the devices.
