Quantifying Aversion to Costly Typing Errors in Expert Mobile Text Entry

Explore a 20-minute conference talk from the ACM CHI Conference on Human Factors in Computing Systems that delves into the impact of typing errors on expert mobile text entry speed. Learn how users adjust their typing pace to minimize costly mistakes, and discover a new model that estimates the effects of risk aversion on typing speed. Gain insights into why current mathematical models may overestimate maximum errorless expert typing speeds by not accounting for these behavioral adjustments. Understand the implications of this research for the design and optimization of physical and soft keyboards for mobile devices.
