Project Progress Summary


Progress
   


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.

Highlights
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.

Links:










Bug Metric

Total Bug Count:

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

Highlights
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.

Links










Work Stress Metric

Work Stress metric mid.png
Please refer to our work stress calculation here.

Highlights
The work stress metric is primarily used as an indicator for the project manager to track and manage the workload of the members. Thus, in the instance where a member's stress percentage is 10% higher than that of the average, the project manager will then consult the member to further understand the situation and see if the workload of the member is indeed overloaded or the member is just being inefficient. Ulitmately, it is still up to the project manager's discretion to follow up on any action plan as follows.

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 shifted important parameters such as token and app ID to a HTTP connection header instead.


  • Perfomance
  1. Gzip - To reduce long period of dependency for a stable connnection, it is critical to ensure that the file size of the required API is kept to a minimum. Comparing the data size between a Gzip file and a text String, Gzip file is calculated to be approximately 10 times smaller. This means that much less time is needed to retrieve the required data. This is critical for us as many users might always constantly be on the move and stable connection might be 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, with many pictures associated to each of the place).
  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 asynchronous and to create a queuing system (5 threads at a time) to download these 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, enabling similar looks for versions all the way back to Android version 1.6, which the standard 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 there is limited resources available pertaining to SherlockActionBar library. Being new to Android development, the learning curve for this library is considerably 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 Maps for Android), the application will download a specific map area pertaining to the user’s itinerary. The maptiles (of .png file format) will then be zipped up so that it can be used to render the map, thus allowing users to view the touring area on the offline map with zooming features. This specificity is done through a customized algorithm to determine the right boundaries and zoom levels for the map for both the travelogue and place offline map. 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
   


  • 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

TESTING METHODOLOGY

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

Reflections

Learning Outcomes
   


Team Reflection

Member Reflection
Zijun mid.jpg

I have learnt to better manage my time by prioritizing my work accordingly. As the Quality Assurance Manager and Assistant Designer, I realized that it is very difficult to develop a native android app without any frameworks as there is a need to cater to different screen sizes for the phones. Sometimes it might look okay on my phone but looks different in another phone. I hope that through this project, I am able to learn things to give a better user experiences for users.

Yukai mid.jpg

I set out to learn hard skills such as technical coding and soft skills such as project management skills, which I believe is still an ongoing process.

However, the learning outcomes since acceptance have been much more overwhelming than I’ve expected. Being the lead developer for offline maps has really tested my patience and perseverance due to the need to meet project requirements and deadlines. I’ve also gained more experience working in an agile development where we have to constantly gauge and prioritize the importance of certain functions, either due to client requirements or insights from user testing.

Melissa mid.jpg

As a designer, it was indeed challenging as it was my first being exposed to Android Coding. Editing the XML layout code was quite different as compared to editing on a CSS template. Furthermore, I have to take consideration to different layouts and densities. Therefore , I have earnt the virtue of being patient and to continue to play around with the layout values to ensure that the outlook of the application appears correctly in different models. Communication is also key amongst the team to ensure the quality of the application is there.

Singlim mid.jpg

During acceptance, I have set out the goal of learning how to develop an android application. I believe I have managed to grasp certain aspects of it and am definitely still looking to improve. In terms of mobile app development, performance and usability of the application is critical. However, this is a challenge as there are many different phone models and versions out there. Some may work, some may not. Therefore, it is always a challenge to make the application available to as many phone models as possible. I have also enjoyed the opportunity of learning from one another. As the project progresses, each of us has forged our strength in different areas. Working with An has also widened my knowledge on many other technical know how such as performance testing etc. As a lead business analyst, I have explored available travel apps and design a survey questionnaire prior the start of the project to decide on interesting features that users would want in a travel app. At the same time, touching up on design prototyping and diagrams to clarify with sponsor and supervisor.

Siew mid.jpg

Through this project, I was hoping to learn how to better manage a team using the agile framework, where workload is fairly allocated throughout the team as well as a good management of change requests throughout the application. Currently, through the logs as well as meetings that we have, I learnt how to manage changes from the client’s, supervisor’s as well as user’s feedback and to prioritize what changes should be implemented. I hope to continue to learn how to better allocate the correct amount of manpower for each functions, and how to communicate better with the other stakeholders involved in our application.
