abstract ;;Quote: studies of transcription typing have identified 34 phenomenons concerning interkey time, typing units, typing errors, eye movements, etc.
abstract+;;Quote: the Queuing network-model human process (QN-MPH) can model 32 transcription typing phenomena
6:3 ;;Quote: typing is slower than reading and faster than choice reaction time
6:3+;;Quote: skilled typing requires natural text and look ahead; stopping span is one or two characters; skill and comprehension are independent
6:3+;;Quote: a concurrent task does not affect typing performance for highly skilled typists
6:7 ;;Quote: 70% of typing errors are detected without reference to the text; pause after omission errors
6:7+;;Quote: substitution errors involve adjacent keys; intrusion errors from short interkey time; transposition errors mostly cross-hand
6:8 ;;Quote: skilled typists tap faster and have a larger eye-hand span; interkey time decreases by a power law
6:8+;;Quote: transcription typing has a 4 character saccade time and a 400ms fixture duration
