Project: VirusTracker

VirusTracker is a desktop app for generating statistics for Covid-19, optimized for use via a Command Line Interface (CLI) while still having the benefits of a Graphical User Interface (GUI). The GUI is created with JavaFX. It is written in Java, and has about 10 kLoC.

Given below are my contributions to the project.

  • New Feature: Added functionality to generate locations that an infected person has been to.
    • What it does: It displays all the locations an infected person has been to within 2 weeks of the current date. (Pull requests #132 , #152 , #278)
    • Justification: This enables users to view the locations that might require additional quarantine measures.
  • New Feature: Added functionality to generate people that an infected person has been in contact with.
    • What it does: It displays all the people that visited a location on the same day infected person had been to that same location. An infected person’s visits are only tracked for 2 weeks prior the current date. (Pull requests #134, #152, #278)
    • Justification: This enables users to view the people who might need to be tested or issued stay home notices.
  • Feature Modification: Updated the GUI to accommodate list of people, list of locations and list of visits.
    • What it does: It displays all 3 lists on the same screen side by side. (Pull requests #111 , #208 , #280)
    • Justification: The original AddressBook only had GUI for a list of people. However, our program required it to be able to handle 3 lists as we needed to keep track of people, locations and visits. Furthermore, there are several commands that require references to more than one list. Hence, I displayed all 3 lists on the same screen.

  • Project management and Team Tasks:
    • Contributed to v1.1 - v1.4 (4 releases) on GitHub.
    • Re-designed the AddressBook GUI to better fit VirusTracker.
      • We realised that the dark theme of AddressBook was not a suitable aesthetic for VirusTracker. We decided that it should look more clinical to fit the medical context VirusTracker will be used in. Hence, I came up with mock-ups of a new GUI design using the mock-up software Figma to allow the team to figure out the direction of our aesthetic. Thereafter, I implemented it within VirusTracker itself. (Pull request #208)
    • Designed the VirusTracker banner and cleaned up the logo
      • The logo was originally of a very low resolution so I recreated the entire logo in Photoshop to create clean edges. Bezier curves were also used to prevent loss of resolution when scaling the image.
  • Documentation:
    • User Guide:
      • Added documentation for the features generateLocations and generatePeople. (Pull requests #165 , #292)
    • Developer Guide:
      • Added implementation details of the generateLocations and generatePeople features. (Pull request #165)
      • Added use cases for the generateLocations and generatePeople features. (Pull request #165)
      • Added design details for the updated GUI. (Pull requests #194 , #292)
      • Added sections to provide a preface, explain how to use the guide and explain notations used within the guide. (Pull request #309)
      • Fix broken links in the table of contents. (Pull request #317)
  • Review Contributions:
    • PRs reviewed (with non-trivial review comments): #133 , #138
