Time Intervals between Keystrokes, Records, and Fields in Data Entry with Skilled Operators
TLDR
This article provides generalized keying rate information in terms of the time between keystrokes, theTime between records and fields, and the burst rates for multiple keystroke in a typical data entry application.Abstract:
Designers of systems which provide for data entry from a keyboard are usually concerned about the rate and manner that keyed data will enter the system. This article provides generalized keying rate information in terms of the time between keystrokes, the time between records and fields, and the burst rates for multiple keystrokes. The time interval data is presented in the form of cumulative relative frequency distribution curves. The analyses are based on more than one million keystrokes of data that were collected with fifteen keypunch operators on an IBM 3741 data entry system in a typical data entry application.read more

Response time and display rate in human performance with computers
TL;DR: Experimental results indicate that frequent users prefer response times of less than a second for most tasks, and that productwlty does increase as response time decreases, however, error rates increase with too short or too long a response time.

Evaluation of Alternative Alphanumeric Keying Logics
TL;DR: Four keying logics for the entry of alphanumeric characters were evaluated and a keying logic that used 36 individual keys for each alphabetic and numeric character was significantly superior to other logics that used push-button telephone-type keyboards.
