Example of two-pass data entry

In this example, Operator 1 can be a person or a recognition engine. If you use a recognition engine for the initial data entry, it runs as a background process so there is no user interface shown.

Table 1. Example of two-pass data entry
Person or recognition engine User Interface AltText [0] AltText [1] AltText [2] Task settings in set.xml file
Operator 1

(initial data entry)

1 1     Show other alt texts is set to -1. (hide alt text)

Blind confirm index is set to -1. (do not compare)

Propagate ToAltText ("1")

ClearAlt Text("0")

    1

(Moved from AltText [0]

   
Operator 2

(initial state)

    1   Show other alt texts is set to -1. (hide alt text)

Blind confirm index is set to 1. (compare)

Operator 2

(after data entry)

2 2 1   Show other alt texts is set to -1. (hide alt text)

Blind confirm index is set to 1. (compare)

The data for Operator 2 data ('2') is now stored in AltText[0] and the data for Operator 1 ('1') is in AltText[1]. In this case, the compare fails, and the operator must enter the same value twice to override the initial value.
Important: You specify the Show other alt texts value and the Blind confirm index value in the set.xml Webpage dialog for the task in Datacap Web Client.
