Start Session

The start session menu provides three ways to enter a session.

Create/Join       Ctrl + G

Create/Join determines whether the client needs to create or join a session. This is the default behavior of the client and also linked to the button.

Create Session       Ctrl+ I

Create session only attempts to create a session. If the session exists, the client will not join the session and sends an error message that the session already exists. This menu item is also linked to the button.

Join Session       Ctrl + J

Join session assumes a session is in progress. If the session is not available the client will display a 'session doesn't exist' error message. Join is also available by clicking the button.

Replay

The replay menu provides a variety of ways to view recorded data. They include: distributed replay, local replay and local replay with a control GUI. The following sections describe the different modes and provides a pocedure for setting up and running a replay from each mode. To learn more about recording see the Record menu item under the Meeting menu.

Distributed Replay       Ctrl + D

Distributed replay provides a way to distribute locally recorded data. The distributed replay session is dependent on a Habanero server to provide the necessary link between the clients. The server can run locally or remotely since the client initiating the session uploads the recorded data to the server and the server distributes the data to the other clients. Once the replay session starts other clients can join but will only see the data relative to the point where they joined the replay session.

Creating a distributed replay involves: running a Habanero server, setting up the replay, notifying the target audience to join the 'replay session' and starting the replay. Use the distributed replay window to select the replay data set, choose the replay speed, define the session name, and the server and port number of the system hosting session.

Local Replay GUI       Ctrl + U

Local replay with a graphical user interface (GUI) provides an addition set of controls to manipulate the recorded data during a replay. The GUI provides start, stop, pause, jump to a mark (if available) and speed adjustment during the replay. It provides time line information, displays a list of the applications that were active during the recording and displays a color-coded list of people who were involved in the session. Each event appears as a color-coded box or circle along the time line. These symbols identify when an event occurred and the color code corresponds to the person who initiated the event.

The Mark List

If marks were created in the replay data set they will appear in this pull-down list. The marks are generated by separate utility, Replay.MakeMarks, and allow you to move through a replay at ten event increments. When you select a mark from the list, Habanero will jump to that point in the replay. The list of marks appear as:

Save/Delete/Duplicate

Save/Delete/Duplicate is available from both the Session Defintion (off-line) and Meeting(on-line) menus. It performs operations on the session definitions. Session definition are session template files that get saved to the habanero.rsc/templates directory unless otherwise defined in the habanero.rsc/user.props file. The default name for each new session defintion file reflects the name of the session and can be modified by editing the name field.

Creating a session definition is easy. It can be accomplished on-line during a session or off-line when the client is in advanced features mode. The templates are created from the information available from the session toolbar. During a session, the client takes a snapshot of the session and saves that information. Off-line the information is defined by the user to create custom sessions. Templates can include: session information(perisitent, anonymous), a participant list, an active tool list and security options.

Saving a session definition is as easy as clicking the button, pressing CTRL + S on the keyboard or by selecting the option from Session Defintion (off-line) and Meeting(on-line) menu. Next, click Save.

To delete or duplicate a session defintion, first select it from the session list, open the session defintion operations window and select delete or duplicate option.

Advanced/Basic Features

The advanced and basic modes define the client's grapicial user interface off-line. The basic features mode is the default setting and provides a simple interface to create or join a session. The advanced features mode is used to create session definitions.
