To design an easy-to-use interface, pay attention to what users do, not what they say. Self-reported claims are unreliable, as are user speculations about future behavior.

MacKenzie, I. Scott, Chen, Javier and Oniszczak, Aleks (2006): Unipad: single stroke text entry with language-based acceleration. In: Proceedings of the Fourth Nordic Conference on Human-Computer Interaction 2006. pp. 78-85.

A stylus-based text entry technique called Unipad is presented. Unipad combines single-stroke text input with language-based acceleration techniques, including word completion, suffix completion, and frequent word prompting. In a study with ten participants, entry rates averaged 11.6 wpm with 0.90% errors after two hours of practice. In follow-on sessions to establish the expert potential, four users entered "the quick brown fox" phrase repeatedly for four blocks of 15 minutes each. Average rates on the last block ranged from 17.1 to 35.1 wpm, with peak rates reaching 48 wpm.

Oniszczak, Aleks and MacKenzie, I. Scott (2004): A comparison of two input methods for keypads on mobile devices. In: Proceedings of the Third Nordic Conference on Human-Computer Interaction October 23-27, 2004, Tampere, Finland. pp. 101-104.

Two mobile device text entry methods were evaluated. The well-known Multitap method was compared to our RollPad method on a new device utilizing a tactile touchpad in place of a keypad. RollPad was well liked by participants. KSPC (keystrokes per character) was significantly lower: 1.42 compared to 2.13 with Multitap. However, no significant difference was found in error rates or entry speed, with speed measured at about 7.3 wpm for both methods.

MacKenzie, I. Scott and Oniszczak, Aleks (1998): A Comparison of Three Selection Techniques for Touchpads. In: Karat, Clare-Marie, Lund, Arnold, Coutaz, JoŽlle and Karat, John (eds.) Proceedings of the ACM CHI 98 Human Factors in Computing Systems Conference April 18-23, 1998, Los Angeles, California. pp. 336-343.

Three methods of implementing the select operation on touchpads were compared. Two conventional methods -- using a physical button and using "lift-and-tap" -- were compared with a new method using finger pressure with tactile feedback. The latter employs a pressure-sensing touchpad with a built-in relay. The relay is energized by a signal from the device driver when the finger pressure on the pad surface exceeds a programmable threshold, and this creates both aural and tactile feedback. The pressure data are also used to signal the action of a button press to the application. In an empirical test with 12 participants, the tactile condition was 20% faster than lift-and-tap and 46% faster than using a button for selection. The result was similar on the ISO-recommended measure known as throughput. Error rates were higher with the tactile condition, however. These we attribute to limitations in the prototype, such as the use of a capacitive-sensing touchpad and poor mechanical design. In a questionnaire, participants indicated a preference for the tactile condition over the button and lift-and-tap conditions.
