Blind FLM: An Enhanced Keystroke-Level Model for Visually Impaired Smartphone Interaction

The Keystroke-Level Model (KLM) is a predictive model used to numerically predict how long it takes an expert user to accomplish a task. KLM has been successfully used to model conventional interactions, however, it does not thoroughly render smartphone touch interactions or accessible interfaces (e.g. screen readers). On the other hand, the Fingerstroke-level Model (FLM) extends KLM to describe and assess mobile-based game applications, which marks it as a candidate model for predicting smartphone touch interactions.
