The screen with the title “Join group” is shown
twice in the diagram. The reason for this is that
when no groups exist a message is viewed in the
screen stating: “No groups in list. Add new from
the menu!” Since no groups exist, the possibility
to join a group by clicking OK should not
be present and the OK button is therefore not
shown in this case. The same screen will appear
if the user chooses “Delete group” from the
menu when the group list is empty. When there
are groups in the list, the other screen is shown
with the group list and the possibility to join one
of the groups.
In later versions, additional fields and screens
will be part of the system. Since private communication
is supported, the setup screen will
have an additional field for choosing between
private and public mode. Joining and editing
of groups will be similar for private and public
communication, but the adding of new groups or
contacts will be different. The reason for this is
that the JXTA proxy does not currently support
searching of groups or contacts. In ITS 1.0,

group list, and when joining the group it is
checked whether the group already exists or not.
Future versions should change this functionality
to a search procedure where the user can choose
to search for a group or contact with the exact
same name as the entered name, or to get a
search result of groups or contacts with similar
names.
In private mode the user will get a list of online
contacts after joining a group, and the menu will
include options for editing the contact list in
addition to most of the existing options. There
will also be a screen where received messages
are printed and the user gets the possibility of
answering the message. Figure 29 illustrates the
screen flow for a future version of ITS. Some of
the screens from the previous screen flow are
left out, since there are no changes.
6 Usage Scenarios
This section illustrates the usage of the ITS with
only three scenarios, although ITS has many
more useful scenarios for travelers.
