Abstract

The disclosure relates to a machine tool device, in particular a handheld machine tool device, comprising at least one control and/or regulating unit and at least one drive unit sensor unit for detecting at least one drive unit parameter that can be processed at least in order to control and/or regulate a drive unit of a machine tool and/or in order to output information to an operator of the control and/or regulating unit. According to the disclosure, the machine tool device comprises at least one operator sensor unit in order to detect at least one operator-specific parameter that can be processed at least in order to control and/or regulate the drive unit and/or in order to output information to an operator of the control and/or regulating unit.
