Mid Term Slides

Project Progress Summary


Currently, Viaxeiros in in their Iteration 9 on 26 February 2013, and in the midst of meeting the upcoming milestone, which is the Midterms presentation, at 26 February 2013.

Currently, since the Acceptance Presentation which is at 5 November 2013, The following main features have been completed:

  1. Native pages for travelogue and places
  2. Download of travelogue for offline usage
  3. Camera functions in the application
  4. Online and offline map display
  5. Improvement of performance and memory issues

Based on the current status of the project, our team has decided to focus only on one of the additional functions proposed in the Acceptance Presentation, which is the Augmented Reality.

Project Highlights
Iterations Descriptions / Highlights
2 Major Delay in Offline map

Prior to the actual start of the coding phase, it has been decided that the offline map feature is going to take much more time than that of other functions as many of us are unknown to any available map technology, let alone one catered to offline usage. Thus, we have planned to start this function early, hoping to overcome the steeper learning curve earlier in the project. Our worries turn out to be correct, where our research in Iteration 1 shows that offline map is much more complex than what we assumed to be. Judging from this, we have made an appropriate change in our schedule, thus assigning a longer time for the creating of the offline map.

4 Increasing Scope to be done

During Iteration 4, in one of the client's meeting, we have come to a conclusion with our sponsor that there should be a change in the requirements of the application. In view of the need to provide a more holistic feel of the application and to cater more wholesomely for the offline purposes, the clients and us decided to include the viewing of travelogues, places as well as the listing of travelogues to be native pages. This has in turn result in a major change in the schedule as some of the functions such as the search will be pushed to the later part of the schedule.

In addition, our group has also discussed among ourselves and feel that one of the additional functions might have to be dropped as there is a high chance that this change in requirement will increase the time needed to complete this requirement.

7 Change in focus for additional functionality

After the discussion with our clients, we feel that focusing on the Augmented Reality might suit the business model of the company better than that of the smart itinerary. This is because the smart itinerary creates a more "gamey" feel, which might contradict in the overall experience of the application. In addition, the smart itinerary might prove to be more troublesome for users as users can only accept the entire travelogue and are unable to edit much of it. Augmented Reality, in the other hand, provides users with an alternate view of the same data, which allows users to explore their surrounding in a more interesting manner. Thus, with these considerations in mind, our team has decided to focus our research on the implementation of augmented reality in the upcoming iterations.

Project Metrics

Schedule Metric

The following shows the summary of our schedule metric thus far:

Schedule metric mid.png
Please refer to our Schedule metric calculation here.

In general, there is a delay in Iteration 3. This is due to having examinations during that period of time. Thus, despite the relatively less functions during that period of time, there is a slight delay in completing the schedule. Due to this, we have decided to increase the time period for the next iteration and also to allocate more tasks to be done then.


Bug Metric

Total Bug Count:

Bug metric mid.png
Please refer to our bug metric calculation here.

There is a spike in bug metrics during iteration 5 due to the coding sessions in iteration 4 as well as after our first user testing. In order to reduce the bug points, we have stopped coding out functions and focus instead on solving the current bugs that we have. Similarly for iteration 7, in order to solve the bugs found, more time has been allocated in iteration 8 to solve the bugs.

Technical Complexity
  • Security
  1. HTTP Request Response Header - User token, application ID and parameters required to retrieve specific APIs were previously appended to a URL. To prevent user information from being compromised, we have then shifted important parameters like token and app ID to a HTTP connection header instead.

  • Perfomance
  1. Gzip - To reduce long period of dependency on a stable connnection, it is critical to ensure that the file size of the required API is kept to the minimum. Comparing the data size between a Gzip file and a text String, Gzip file is calculated to be approximately 10 times smaller. This is critical for us where users are always on the move and stable connection is hard to get. At the same time, the data we require from QIITO is known to be relatively huge (A travelogue can contain 100s of places).
  2. Lazy Loading - The idea of lazing loading is to reduce the required time needed to load and display a page. This is especially crucial when our application is required to retrieve and display a large number of images. What we have done is to make the downloading of images asyncronous and to create a queueing system (5 threads at a time) to download the images. Once an image is downloaded, it will be cached in the phone's memory and will be displayed on the page.

  • SherlockActionBar/ Fragments
  1. SherlockActionBar library allows us to create "ICS looking" apps, that look the same all the way back to Android version 1.6, which the Android sdk does not offer. The features of the library include Actionbar, tabs, overflow, split action bar, viewpager etc. Now, we are able to create multiple interfaces within a single activity across all Android OS versions. This allows a better manipulation of functions when users navigate through the application. For example, the navigation between a web view and a native view with differing interface will only require two different fragments, instead of creating a new activity. In addition, due to the flexibility of fragments, each of them can be recycled and used in other activities within the application, reducing the need for repeated codes. The complexity lies on the fact that resources pertaining to SherlockActionBar library could be limited at times and as a new Android developer, the learning curve is steep.

  • Offline Map
  1. Whilst overseas, users may have difficulty obtaining data connectivity to have access to the full functionalities of Google Maps. With the implementation of OSMDroid (Open Street Map Droid), the application will cache a specific map area pertaining to the user’s itinerary. This allows users to view the touring area on the offline map, complete with zooming features and search function of that particular area. Being an open-sourced package increases the difficulty of implementation, due to lack of proper documentation to explore customized functions. There are also certain restriction of its usage due to it being free, thus algorithms for download are required to be stricter.

  • Deployment Version - v2.1
  • Development Environment - Deployed in Android Google Play Store
  • Database - Used the phone's internal database, SQLite, Qiito Database (via API)
  • Coding Language - Java and XML

Our participants for UT2 consist of Existing and new Qiito App Users. For existing users, we asked our friends from UT1 to test on our App to see if our App has improved from UT1. We also target new users by inviting our fellow SMU friends from different schools to try out our App.

We conducted our Usability Testing 2 in a SR. Firstly, our team will brief them what our App is for. If the participants have Android phones, we will ask them to download our app from GooglePlay. If they have no Android phones, we will pass them our phones to test on. Like UT1, we gave our participants a sheet of instructions consisting a set of scenario-based tasks. We would then sit beside them and observe how they interact with our application. We should not guide them unless they are confused or don't know how to proceed. Our team would also note down the areas which are confusing.

After they have done with the tasks, we will then ask them to fill up an Online Feedback Form
