Schematic representation of the definition and aggregation of the timing-related keystroke features. (a) Keystroke features were derived from timestamped keyboard interactions. (b) For each keystroke feature, five summary statistics (i.e. vectors) were calculated to aggregate all typing sessions per day. (c) The five vectors for each feature were then aggregated into 14 days by taking the median value.

PPL: Press-Press Latency; RRL: Release-Release Latency; FT: Flight Time; Pre-CS: Pre-Correction Slowing; Post-CS: Post-Correction Slowing; APP: After Punctuation Pause; HT: Hold Time; CD: Correction Duration.
