FIELD: data input devices.
SUBSTANCE: device has base, at least one assembly, consisting of key and means for determination of operation of key, first means for determination of displacement of device elements relatively to one another, while the key is mounted with possible outside access to it, a platform is provided, mounted with possible displacement relatively to base, key is mounted with possible displacement of it together with platform relatively to base, first means for determination of device elements mutual displacement is mounted with possible recording of platform displacement relatively to base, and means for detecting key operation is made or positioned relatively to key in such a way, that it can record well operation in neutral position, and/or in case of platform displacement from neutral position.
EFFECT: higher efficiency.
