<div class="paragraph"><p><span class="blue"><em>Version 1.0, March 2016</em></span></p></div>
<div class="paragraph"><p>Welcome as a user of <em>Subsurface</em>, advanced dive logging software with
extensive infrastructure to describe, organize, interpret and print scuba
and free dives. <em>Subsurface</em> offers many advantages over other similar
software solutions, including compatibility with Windows, Mac-OS/X, Linux (many
distributions) and Android (iOS under development). In addition, <em>Subsurface</em> is
open-source software that allows downloading dive
information from most dive computers.</p></div>
<div class="sect1">
<h2 id="_introducing_subsurface_mobile">1. Introducing Subsurface-mobile</h2>
<div class="sectionbody">
<div class="paragraph"><p><em>Subsurface-mobile</em> is an extension of <em>Subsurface</em> on laptop and
tabletop computers. It runs on Android smartphone and tablet devices and is a
tool for viewing or sharing dive information at dive sites where a larger
computer is not useful. <em>Subsurface-mobile</em> also allows
the gathering of GPS locations where dives are performed.</p></div>
<div class="paragraph"><p>A version of <em>Subsurface-mobile</em> for iOS is under development but not yet
ready for testing.</p></div>
<div class="paragraph"><p>While <em>Subsurface-mobile</em> allows one to enter and save dive information
using an Android device, users of <em>Subsurface-mobile</em> typically use the
mobile app as an extension of the laptop/desktop version of <em>Subsurface</em>.
This allows the storage of dive logs on the Internet and which
can be shared by the Android version as well as the desktop version.
While the desktop version of <em>Subsurface</em> shows much more detailed information
for each dive, the mobile version allows one to have a more accessible dive log
on a dive trip, useful for proving dive experience to dive shops or to review
previous dives.</p></div>
<div class="paragraph"><p><em>Subsurface-mobile</em> allows one to:</p></div>
<div class="ulist"><ul>
<li>
<p>
Download existing dive log information from the Internet.
</p>
</li>
<li>
<p>
View this information on an Android device.
</p>
</li>
<li>
<p>
Edit many of the dive log data fields, e.g. divemaster, buddy,
equipment or notes about a dive.
</p>
</li>
<li>
<p>
Create and add new dive records to one’s dive log.
</p>
</li>
<li>
<p>
Store the updated dive log on the Internet.
</p>
</li>
<li>
<p>
Record, store and apply GPS positions of dives.
</p>
</li>
<li>
<p>
View the localities of recorded GPS positions and of dives
on a map.
</p>
</li>
</ul></div>
<div class="paragraph"><p>These items are discussed in greater detail in the following text.
What <em>Subsurface-mobile</em> does not support (at this time) is downloading
dive data directly from a dive computer. That still has to happen with
<em>Subsurface</em> on a desktop or laptop computer. We are investigating ways
to support downloading from a subset of the supported dive computers on
Android devices, but this is not yet ready for testing.</p></div>
</div>

<div class="sect1">
<h2 id="_installing_em_subsurface_mobile_em_on_an_android_device">2. Installing <em>Subsurface-mobile</em> on an Android device</h2>
<div class="sectionbody">
<div class="paragraph"><p>Find <em>Subsurface-mobile</em> in the <em>Google
Play Store</em>. Search for <em>Subsurface-mobile</em> and install it.</p></div>
</div>
</div>
<div class="sect1">
<h2 id="_using_em_subsurface_mobile_em_for_the_first_time">3. Using <em>Subsurface-mobile</em> for the first time</h2>
<div class="sectionbody">
<div class="paragraph"><p>Upon starting <em>Subsurface-mobile</em> for the first time, a Subsurface
splash screen is shown while the program loads. On some devices this
may take several seconds. After loading, the <em>Cloud Credentials screen</em> appears
(see image below).</p></div>
<div class="imageblock" style="text-align:center;">
<div class="content">
<img src="mobile-images/landingscreen.jpg" alt="FIGURE: Mobile landing screen" />
</div>
</div>
<div class="paragraph"><p>Since <em>Subsurface</em> is largely dependent on a dive log saved on the Internet,
provide a user-ID and password for access to the <em>Subsurface Cloud</em>. These
credentials are obtained by opening the desktop version of <em>Subsurface</em> and
by clicking <em>File → Preferences → Network</em>, explained in detail in the
user manual for the <em>Subsurface</em> desktop version. Once the account has
been created and verified using the desktop version one can use <em>Subsurface-mobile</em>.</p></div>
<div class="paragraph"><p>When entering a password, it is possible to check
a checkbox that enables the text of the password to be shown. Checking the
check box labelled "Remember" allows <em>Susburface-mobile</em> to keep the
credentials for subsequent logins (see image above).
Having entered the credentials, tap the disk icon at the bottom of the screen.
<em>Subsurface-mobile</em> attempts to download the existing dive log from the_Subsurface_ cloud
server. Appropriate messages are shown onscreen. Finally
a list of dives are shown.</p></div>
</div>
</div>
<div class="sect1">
<h2 id="_local_copy_of_the_dive_log_and_synchronisation_with_internet">4. Local copy of the dive log and synchronisation with Internet</h2>
<div class="sectionbody">
<div class="paragraph"><p>Once the dive
list has been downloaded from the Internet, <em>Subsurface-mobile</em> keeps a local
copy on the mobile device. This means that, if there is no Internet connection
at a dive site, one can still access the local copy and view and manipulate
dive information. If there is Internet connectivity, <em>Subsurface-mobile</em> accesses
the Internet-based dive log to verify that the local copy is still the
same as the Internet-stored copy. If not, the local copy and the copy on
the server are synchronised.</p></div>
</div>
</div>
<div class="sect1">
<h2 id="_a_few_remarks_about_the_user_interface">5. A Few Remarks About The User Interface</h2>
<div class="sectionbody">
<div class="paragraph"><p>At the bottom of many Subsurface-mobile screens is a round button that provides for
several actions and which allows the selection of the main affirmative action
(see image above and image below).
On Android devices, use the Android Back
button for "cancel", "discard" or "back" actions. For example, when
editing dive information, tapping the action button saves the changes, the
Android back button can be used to cancel the edit without saving changes.</p></div>
<div class="imageblock" style="text-align:center;">
<div class="content">
<img src="mobile-images/actionbutton.jpg" alt="FIGURE: Action Button" />
</div>
</div>
<div class="paragraph"><p>Instead of the more traditional "hamburger" menu button in the top left or
right corner of the screen to open menus, <em>Subsurface-mobile</em> uses a
different user interaction philosophy based on the Kirigami framework
developed by the Plasma developers. To open the main menu one has
three options:</p></div>
<div class="ulist"><ul>
<li>
<p>
Tap on the right-arrow symbol in the lower left corner of the screen
(easy to reach for hand held devices)
</p>
</li>
<li>
<p>
Swipe towards the right across the left edge of the screen
</p>
</li>
<li>
<p>
Drag the action button visible on most screens with the main action to
the right
</p>
</li>
</ul></div>
<div class="imageblock" style="text-align:center;">
<div class="content">
<img src="mobile-images/menu.jpg" alt="FIGURE: Dive management subpanel" />
</div>
</div>
<div class="paragraph"><p>The images above indicate some of the important features of the menu system.
On the left is the main menu that is activated as described above. In the middle is
the menu that opens if one taps the <em>GPS</em> option on the main menu. On the right is
the menu that opens if one taps the <em>Manage Dives</em> option on the main menu.</p></div>
<div class="paragraph"><p>Similarly, the context menu (currently only available on the dive details screen) can be
opened one of these three ways:</p></div>
<div class="ulist"><ul>
<li>
<p>
Tap on the left-arrow symbol in the lower right corner of the screen
</p>
</li>
<li>
<p>
Swipe to the left across the right edge of the screen
</p>
</li>
<li>
<p>
Drag the action button to the left
</p>
</li>
</ul></div>
</div>
</div>
<div class="sect1">
<h2 id="_viewing_the_dive_list">6. Viewing the Dive List</h2>
<div class="sectionbody">
<div class="paragraph"><p>Most of the actions of <em>Subsurface-mobile</em> center around the dives on the
dive list. While the dive list is loading from the cloud,
a message appears at the bottom of the screen, indicating that the cloud is
being accessed (see image on left, below). Once the list is loaded one can scroll up and down.
Tapping a dive on the list brings up a display of <em>Details View</em> for that dive (see image on right below).
This includes the dive profile as well as additional information and notes.</p></div>
<div class="imageblock" style="text-align:center;">
<div class="content">
<img src="mobile-images/divelist.jpg" alt="FIGURE: Dive list screen" />
</div>
</div>
<div class="paragraph"><p>One can view other dives by swiping the <em>Details view</em> to the right (for the
previous dive) or to the left (following dive).</p></div>
</div>
</div>
<div class="sect1">
<h2 id="_editing_dive_details">7. Editing dive details.</h2>
<div class="sectionbody">
<div class="paragraph"><p>At the bottom of the dive details screen the <em>Action Button</em> contains a pencil (image on right, above).
Tapping the button brings up a panel with edit boxes that allows one to
change the existing dive information, e.g. adding text to the dive notes
or changing the names or values of some of the information (see image below).
It may be necessary to scroll the window to access all the information.
At the bottom of the edit screen is a <em>Save</em> action button. Tap this to save
the new information. Having saved the data, the dive list screen is
updated and shown. To cancel any edits, tap the Android Back Button.</p></div>
<div class="imageblock" style="text-align:center;">
<div class="content">

</div>
<div class="sect1">
<h2 id="_adding_a_new_dive_to_the_dive_list">8. Adding a new dive to the dive list</h2>
<div class="sectionbody">
<div class="paragraph"><p>It is also possible to add an additional dive to the existing dive list. On the
main menu tap <em>Manage dives → Add dive manually</em>. This opens a screen that is
identical to the editing screen discussed above. When a dive is added manually, one
cannot directly add a dive profile from a dive computer. However, if one does not use a
dive computer, the duration, depth and several other bits of information about
the new dive can be entered. The <em>Action button</em> at the bottom of the screen
contains a disk symbol. Tap this to save the new dive. To cancel any edits, tap the Android Back Button.
The left-hand image below shows a screenshot of a dive being created and the right-hand image shows
the same dive in <em>Details View</em>.</p></div>

<div class="sect1">
<h2 id="_deleting_a_dive">9. Deleting a dive</h2>
<div class="sectionbody">
<div class="paragraph"><p>The <em>details view</em> of a dive has a context menu on the right-hand side that can be activated as described above
(e.g. by tapping the arrow icon at the bottom right of the screen or by dragging the <em>Action Button</em> to the left).
The context menu has a single item: "Delete dive". If this option is tapped, the dive shown in the <em>Details View</em>
is deleted. One has a brief opportunity to undo the delete by tapping the <em>undo</em> message that appears at the bottom of
the screen. If the <em>undo</em> message is not tapped, the dive is deleted.</p></div>

</div>
<div class="sect1">
<h2 id="_dive_log_management">10. Dive log management</h2>
<div class="sectionbody">
<div class="paragraph"><p>A central part of <em>Subsurface-mobile</em> is the ability to store the dive
log using the <em>Subsurface</em> cloud storage.
This provides security against loss or damage to the dive information caintained in a local copy of
the dive log and allows the desktop version of <em>Subsurface</em> to
access changes made using the mobile device. This ability is accessed
throug the main menu (by dragging the Action Button to the right, or
alternatively tap the right angle button at the bottom left of the screen).
Tap the option <em>Manage dives</em>, enabling a number of options:</p></div>
<div class="sect2">
<h3 id="_add_new_dive_manually">10.1. Add new dive manually</h3>
<div class="paragraph"><p>This is described above under the section dealing with the dive list.</p></div>

</div>
</div>
<div class="sect1">
<h2 id="_recording_dive_locations_using_gps">11. Recording dive locations using GPS.</h2>
<div class="sectionbody">
<div class="paragraph"><p>The fact that most smartphones have GPS facilities allows one to record
the locations of dives. One can take the smartphone on the dive boat
during a dive and locations will be automatically recorded at regular intervals.
These locations can then be applied to dives in the dive list. Here is how it’s done:</p></div>
<div class="sect2">
<h3 id="_setting_up_the_gps">11.1. Setting up the GPS</h3>
<div class="paragraph"><p>Open the main menu and tap <em>GPS → Preferences</em>. Now specify the way
in which GPS data need to be automatically collected (image on right, below). One can specify that
data are collected at regular intervals, e.g. every 10 minutes, or at regular
distances, e.g. after the boat has moved more than 200m, or a combination of
both of the above approaches. Provide the appropriate information and
tap the <em>Save</em> action button. The program is now ready to collect GPS positions.</p></div>

<div class="paragraph"><p>Assuming that all the dives have been entered into the dive log or have
been downloaded from the <em>Subsurface</em> cloud, one can apply the GPS positions to
these dives. GPS positions can therefore only be applied to dives in the dive list.
From the GPS subpanel, tap <em>Apply GPS fixes</em>. The dive list contains the start
and end times of each dive. Now, <em>Subsurface-mobile</em> applies the first
GPS position that falls within the dive period of each dive. This results
in a GPS position for each dive that is saved as part of the dive list.</p></div>
