Project

Improving usability in the Tracker Capture app

About the project

Improve the Tracker Capture app in DHIS2 by adding a data view of previous records in the MNCH / PNC programme. Previous records should only be shown for ANC visit 2-4+, as no records are available at first visit. Other improvements that may be implemented include showing the difference in data (when applicable), and give visual feedback to the user if the entered data contains errors or suspicious values. I.e if the patient have lost weight since the last visit, the difference should be shown with a warning message.

Requirements

• Ability to check old data on same site
  • Add a new column with previous records
  • The records shown should be default show the previous visit
  • No column for previous visits should be shown on ANC 1st visit
• (Optional) View differences in data from last visit
  • Show the difference where applicable
  • Validation in input compared to previous records
  • Use a drop-down menu to change which visit to show previous records from

Time schedule

Milestone 1: 8th November:

• Create wiki page

Milestone 2: 22th November:

• Development environment ready
  • Demo server up and running at http://dhis.mrbjoern.com

Milestone 3: 6th December:

• Learn basic Angular (early in sprint)
  • A basic understanding of Angular is required by all team members before the group can start implementing new features.
• Implement new features in app
  • Primary focus on implementing a new column showing data from previous visit
  • Implementing input validation can be done slightly in parallel with main task
• Test application - The app should be tested to verify that:
  • The new features works as expected

  • The new features does not introduce new defects to the Tracker Capture app
• Write essay
  • Requirements for essay, TBA

Final delivery: 11th December:

• Working app to be delivered
• Deliver essay

Known issues

• There have been some issues with the new column in Firefox 41.0.2 on Ubuntu 14.04. Changes done to the source code were not refreshed in the browser. Possible fixes might be to refresh with CTRL + F5, or clearing the browser cache.
• There was a big difference with how each browser handled the HTML code recieved from the local server. In the rows where the user is supposed to only be able to type in numbers as inputs, Chromium handles it by not allowing the user to type in numeral expressions. This includes number but also signs such as +,- and e. Firefox doesn't handle it in any way like Chromium does so DHIS2 ends up outputting an error should the user type in anything but a number.
