navigation is done via connectors that can have filtering conditions which help make specific graph sections
either visible or hidden during a normal operation.
1.4.2.2 Connectors & adjacency
A connector is a link between two nodes. A node may have embedded conditions that will be evaluated prior
to navigating to the next node. When the condition evaluation is “false” the node is not suitable for
navigation, and won’t be accessible on the workflow session. The syntax of the conditions is defined in the
Conditions, evaluation, & navigation section of this guide.
1.4.2.3 Graph / workflow entry point
The first node in a graph is defined by the Home button node in the EC Workflow Designer. When a user
presses the Embedded Capture button, the first displayed screen is built by evaluating all the nodes that are
created under it.
1.4.2.4 Graph / workflow final node / exit condition
A graph navigation termination/exit point will occur once the workflow does not have more nodes to
navigate after evaluating its conditions and adjacencies. Once the workflow navigation is terminated, HP EC
will return the control to the home screen menu of the device.
Given a node of the graph, each navigation step will evaluate the following nodes availability and conditions.
The end point situation (termination) will occur once there are no nodes or no valid nodes to navigate
(conditions = false). Also, it will terminate the user interaction on the control panel once there are only
“scheduled” nodes to be executed in background.
1.4.3 Node types
1.4.3.1 Home screen button (+icon)
The Home screen button node is the entry point for HP Embedded Capture at the device control panel. The
administrator will define the following visible information: title, description, and icon image.
1.4.3.2 Menu Option
A menu option is a filter which allows the administrator to define menus and submenus during the workflow.
Having multiple menu levels guides the user across complex structures, and/or enables extended filters. A
menu option displays during navigation on the control panel, and a set of multiple nodes and/or menu
options are represented as a list menu requiring the use to select the next step.
1.4.3.3 Dialog screen
A Dialog screen is typically used to display information on the control panel. Screen content is flexible, and is
defined by the administrator. It can contain session macros and dynamic data such as processes results
(number of scanned pages, number of sent files, scanned documents file type, etc…).
1.4.3.4 Form screen / Forms
A Form screen is intended to capture user information in real time. The user will be prompted to enter
information in predefined fields. Form screens may be built by multiple fields and multiple types (string,
number, etc…) including masks defined with regular expressions.
1.4.3.5 Process
Digitally sending documents to any destination is enabled at the Process level. A Process node allows
defining the process type and its parameters by using static information or session information through
