摘要

The invention relates to a method for operating a lift system, comprising a call input device (1, 1'), at least one touchscreen (13) for inputting a call for a lift. The touchscreen (13) has at least one functional identifier (16, 16'). When a functional identifier (16, 16') is touched, at least one input signal is generated. The call input device (1, 1') converts into a special input mode for a time-aligned or location-aligned generation of several input signals.
