This paper explores the impact of rest duration on recovery from cognitively demanding tasks, focusing on pen input features as an indicator of load and recovery. We designed a user experiment involving a cognitively loading task with three levels of difficulty, followed by a controlled rest period, and then a fixed difficulty task. The participants answered the tasks by writing alphabet letters on a tablet monitor. Subjective ratings validated the increasing difficulty of the first task (Friedman ANOVA pp
