Hi All
I would argue that a data entry screen and its associated text boxes 
etc. are input methods, hence the alternative name of input forms.

The workstation operator inputting the data actually aquires the data 
from external sources such as customers either verbally or from 
written/printed documents.

Another example might be the supermarket checkout. Aquiring the data 
would be the process of a customer collecting the required items from 
the shelves and the checkout operator inputs the data from the barcode 
labels using a scanner or the keyboard.
