WEIGHT CHECKING METHOD AND APPARATUS

摘要

A compact data entry system comprises functional zones (2) uniformly divided over an input surface and switches (6) organized in functional groups. Each functional group of switches (6) is associated with a functional zone (2). A functional zone (2) is activated when at least one of its associated functional groups is activated. The system further comprises a processing device (3). The processing device (3) detects the activation of said switches (6) and further detects the activation of a functional group of switches (6) after the member switches (6) of said functional group are activated. When activation of a functional group of switches (6) is detected, the processing device (3) activates a function corresponding to the activated functional group.
