1/ Why do people make so many errors in touchscreen typing, and how do people fix them?

Comments
🔹Slips - motor execution deviates from the intended outcome;
🔹Lapses - memory failures;
🔹Mistakes - incorrect or partial knowledge.
Typoist captures them all!
Typoist extends the computational rationality framework ( https://crtypist.github.io ) for touchscreen typing. It simulates eye & finger movements and predicts how users detect & correct errors.
🚀It makes it possible to evaluate designs before undertaking an empirical study.
🚀It affords new methods of data augmentation in conditions where empirical data may be hard to collect.
🚀It opens the door to a new way of theorizing about errors in HCI.
