<div>Hello Folks,</div><div><br></div><div>Perhaps the solution is to have a property of the learning object that allows you to select the type of navigation you require for your project.</div><div><br></div><div>Projects that use only non-connector pages, or projects that only use connector pages in the same manner that the TOC is used i.e. as a link to other pages but without any intention of setting up a specific route, or routes, through a project will require the standard linear navigation.</div>
<div><br></div><div>Projects that use connector pages to set up specific routes through a project need a historic back button. Since the back button is historic, it follows that if there is a next button it should traverse you forward through the history if you have previously been pressing the back button. However there are only a few connector pages. The standard Xerte pages lack any capability to provide connections so once you reach one of these pages, as a result of following a connection, the only way to leave the page will be to use the navigation buttons. Which is why there needs to be at the point where the next button runs out of history it must revert to offering a linear next move. </div>
<div><br></div><div>Consider again the MCQ connector page example</div><div>Each of the answer options can link to a sequence of none connector pages, i.e. If the connector page is P1 then <br>option 1 may go to P2 which leads to P3 to P4 and P5 is a redirector page to P10<br>
option 2 may go to P6 which leads to P7 to P8 and P9 is a redirector page to P10
</div><div><br></div><div>P2 through P4 and P6 through P8 are not connector pages.</div><div><br></div><div>The user is on P1, they select option 2 and the connection takes them to P6. The user is now on a non-connector page so the only way forward is the linear next to p7 then to p8. If the user now clicks the back button they go back historically to p7, then back again historically to p6. The next button will historically take them to P7 and then to P8, at which point there is no further history to inform the next button, so it reverts to a linear next taking the user to P9.</div>
<div><br></div><div>If the user instead chooses option 1 they follow the route P2, P3, P4, P5. P5 is a redirector connector which disables the navigation, preventing what otherwise would have been a linear next button giving access to P6. P5 provides a connection to P10.</div>
<div><br></div><div>In summary IMHO</div><ol><li>Non-connector projects and projects that do not use connectors to set up specific routes through a project need the linear navigation.</li><li>Connector projects that set up specific alternative routes through a project, or part of a project, must have historic back buttons. Preferably they will also have historic forward buttons which default to a linear next when there is no history to inform the next action. However it should be OK though possibly occasionally confusing to provide only a linear next as the connector pages tend to be used with navigation disabled and the navigation is used when you reach non-connector pages.</li>
<li>This may be best provided by use of a navigation option on the learning object as both connector and non-connector projects will want to use the project option that does not provide a project menu.</li></ol><div>Kind regards</div>

The idea of providing a linear element to the next button, only when the user has no legitimate historic next value, is really to accommodate the difference between Xerte and a web page.

</div><div><div><p class="MsoNormal" style="margin-left:72.0pt"> </p><div><p class="MsoNormal" style="margin-left:72.0pt">Hi folks,</p></div><div><p class="MsoNormal" style="margin-left:72.0pt"> </p></div><div><p class="MsoNormal" style="margin-left:72.0pt">
I'm sorry that it has taken me a while to respond to this thread, I have been otherwise engaged for most of yesterday and today and before I could respond adequately I needed to check a few things.</p></div><div><p class="MsoNormal" style="margin-left:72.0pt">
</p></div><div><p class="MsoNormal" style="margin-left:72.0pt">The standard Xerte project has to date been treated as if you are reading a book. No history just turn to the previous or next page relative to the one you are currently viewing. When you use the TOC you are just opening the book at a new page. Back and Next are then relative to that new page.<br>
<br>The Connector pages introduced a different paradigm for the project. This paradigm required a historical back button. As an example consider a multiple choice connector page. Each of the answer options can link to a sequence of none connector pages, i.e. If the connector page is P1 then <br>
option 1 may go to P2 which leads to P3 to P4 and P5 is a redirector page to P10<br>option 2 may go to P6 which leads to P7 to P8 and P9 is a redirector page to P10<br><br>The historical back is needed to ensure that if you traverse backward from P8 to P7 to P6 that the next backward action does not take you to P5 but to P1.<br>
<br>This inevitably clashes with the book paradigm when you use the TOC which is what Julian found. It will inevitably feel a little strange to Xerte users who are used to the book paradigm. However it does mirror the way a back button works in a web browser, so in a sense it will be what will be expected by anyone opening a Xerte project for the first time.<br>
<br>However browser users will be confused by the Xerte next button, as browsers that offer a next button base their next on the browser history. Such browsers (IE, Opera) appear to operate by building a history and maintaining a pointer as the history is navigated. Whenever a link is followed (rather than a back or next button) the "next" half of the history is deleted, so that on page exit the current page is added as the most recent page in the history.</p>
</div><div><p class="MsoNormal" style="margin-left:72.0pt"> </p></div><div><p class="MsoNormal" style="margin-left:72.0pt">If there are to be on offer in Xerte a choice between the original navigation or historic navigation then the historic navigation would be improved if it also was reflected in the operation of the next button.</p>
</div><div><p class="MsoNormal" style="margin-left:72.0pt"> </p></div><div><p class="MsoNormal" style="margin-left:72.0pt">I have performed some tests in opera to figure out what is going on and have attached a pdf file to explain everything. The pdf file opens with a worked example of how a historic navigation that accommodated a back and next button would operate. The last page identifies the rules that would be required in Xerte to implement such a navigation in the xerte navigation.</p>
</div><div><p class="MsoNormal" style="margin-left:72.0pt"> </p></div><div><p class="MsoNormal" style="margin-left:72.0pt">I hope this helps. The example can take a little effort to get your head around, but the actions that need to happen with respect to each button are, I think pretty straight forward to implement for someone who knows there way around the appropriate Xerte flash file.</p>

<p class="MsoNormal" style="margin-left:252.0pt"><span style="color:#1f497d">I think it's fine the way it is now with back being history back and next being next numeric page but if you've found inconsistencies with the history back perhaps it would be better to revert back to what it's always been. Not sure about author control wouldn't that lead to confusion where sometimes it's history and sometimes it's linear?</span></p>

What do you think: we made the back button in the interface go back in history, rather than back in pages: this seems to work well in some situations, but whilst testing, I have hit back several times and not gone where I expected to, and can’t go forward: do you think we should have it so that the developer can chose which way it works?</p>
<p class="MsoNormal" style="margin-left:252.0pt"> </p><p class="MsoNormal" style="margin-left:252.0pt">So, for a linear interface, it works as it did before, going back and forth on page numbers; if it’s a menu driven piece, it goes back in history?</p>
<p class="MsoNormal" style="margin-left:252.0pt"> </p><p class="MsoNormal" style="margin-left:252.0pt">I think the problem I found in terms of inconsistencies is that forward always takes you next, rather than forward in history when back goes back in history rather than pages (read that again carefully).</p>
<p class="MsoNormal" style="margin-left:252.0pt"> </p><p class="MsoNormal" style="margin-left:252.0pt">Next can’t be forward, as it’s the main way of getting to the next, unvisited page.</p><p class="MsoNormal" style="margin-left:252.0pt">
</p><p class="MsoNormal" style="margin-left:252.0pt">This should do what the user expects because it grates when you don’t go where you wanted.</p><p class="MsoNormal" style="margin-left:252.0pt"> </p><p style="margin-left:252.0pt">
