Our project will look at the usability of the Tracker Capture app in DHIS2. We will focus on fulfilling the requirements stated by the users, but also look into other possible usability improvements.


Group members

Summary of requirements

  • Visualize the previous data from the database dynamically
  • Further improve usability of the app

Technologies

We foresee developing the existing web application and therefore using the following web technologies: HTML5, CSS, Javascript, Hibernate, PostgreSQL, Spring, Maven, JSON. Although this may be subject to change as the project develops.

Milestones

Milestone 1: 8th November: Finish project planning; Document features and architecture on Wiki

Milestone 2: 22nd (Delayed: 23rd) November: Initial, low-fidelity HTML prototype

Milestone 3: 4th December: Final product

Final delivery: 11th December

Presentation: 17th December

Progress

Meetings

  • Nov. 6th: We decided on a schedule for weekly meetings on tuesdays from 10:15 - 12:00. Communication channels established by exchanging emails and connecting on facebook for IM communication. Initial vision and plan developed.
  • Nov. 10th: Cancelled due to group members being sick.
  • Nov. 17th: Sum up of current progress, and collective work session.
  • Nov. 23rd: Finished the static HTML prototype
  • Nov. 24th: Mapping way forward on Webapp
  • Nov. 25th: CANCELED
  • Dec. 1st:
  • Dec. 3rd:
  • Dec. 4th: Project installation
  • Dec. 8th: Frontend development: JS Exploration
  • Dec. 9th: Frontend development: Implementation and testing
  • Dec. 10th: Frontend development: UX upgrades

Division of Workload

  • Emil: Low-fidelity prototypes, UX dev, displaying previous data values on HTML side of things
  • Mwiza: Responsible for retrieving previous data values on the javascript side of things
  • Nico: Setup postgres-database & hibernate connection, responsible for additional usability changes

Changes to The Tracker Capture App

Main Task - Displaying Previous Data Values

The main task in our assignment was to show users of the Tracker Capture App data entry the data values of previous events. In our final solution (as seen above in the screenshots-section), you can see that we have added more columns to the data-entry table to the left of the input field. These corresponds to earlier event's data values. During the development, we had to make a choice about what events we would include as the previous "events", since it was not specified in the assignment. Out options were to either list previous events from within the same program stage (for instance ANC-Visit 2-4)

In addition to the main task of this assignment, which was implementing the ability to view data entries for previous events when entering data, we have made some additional changes to the Tracker Capture App that we believe could enchance the user experience.

Changing Event-ordering Within a Stage from Right to Left to Left to Right

In the default Tracker Capture App, when creating a new event in a stage, new events are added to the left of the previous one. We found this confusing, as events within stages would come in reverse chronological order when read from left to right. This contrasts with the order stages are found in a program, and also how we have added the previous values of events to the left of the data-fields. By simply changing the order, we feel the layout for a program with it's stages and events is more intuitive.

Changes to the Buttons

In the existing app, input data is validated as soon as it was entered in (for instance, writing a non-number in a number field would give feedback on incorrect input). This left the "Validate"-button without much function, so we decided to remove it to reduce clutter and confusion.

We also changed the color of the "Complete" button to a color we felt was more suited for the action of completing a form.

Learning Outcomes

Suggested improvements to Tracker Capture App

  • Data validation:using html, for example in the section Stage.programStageDataElements it would be better to validate value Weight and CD4 count i.e not allow negative inputs.
  • Standard names for controls, for example the "weight" label appears as "weight" in one instance and as "Infant weight" in another, although it refers to the same thing.
