Abstract
A portable input apparatus permits an elevator destination call to be generated remotely from an associated elevator installation with respect to time and location. The input apparatus can be formed as, for example, a wristwatch having a user interface including a first display for visually indicating data, a first keyboard for the manual input of data or travel commands and an audio unit for the acoustic input of data or travel commands and for the generation of audio information to the elevator user. A destination floor identification, such as the English word "twenty-seven", can be an acoustic command destination call entered into the input apparatus and indicated on the first display as "27" whereby in the proximity of the elevator installation, the destination call is automatically communicated to an elevator control of the elevator installation. The elevator control then communicates to the portable input apparatus the identity of the elevator car that has been assigned to serve the call.
