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
	User Interface	AltText [0]	AltText [1]	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)

Operator 2's data ('2') is now stored in AltText[0] and Operator 1's data ('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 task's set.xml Webpage dialog in Taskmaster Web.
