“ ... there are no simple 'right' answers for most web design questions (at least not for the important ones). What works is good, integrated design that fills a need--carefully thought out, well executed, and tested. ”

-- Steve Krug, Don't Make Me Think, p. 136

Valk, Mary Ann (1990): Comparing Touchscreen to Speech Input in the Control of a Simple Batch Process. In: D., Woods, and E., Roth, (eds.) Proceedings of the Human Factors Society 34th Annual Meeting 1990, Santa Monica, USA. pp. 419-423.

“Thirty subjects used a process control simulation to make six batches of ice cream each, using touchscreen input three times and speech input three times. Touchscreen and speech inputs were statistically compared for time to task completion, process control related errors, wrong input mode errors, input-device-related errors, total errors, and opinions about preferences and feelings of control. A touchscreen is the recommended operator input device for control of simple batch processes, based on the results of this experiment.”
