Contextual inquiry with patients and healthcare practitioners
This was the first phase of the project. We aimed at understanding the limitation and benefits of the current system, observe the environment and also understand patients’ needs and requirements.

An interaction with patients

A few examples of design sessions

Moving from Requirements to Design
Two participatory design sessions were conducted at the health centre. Eight participants were divided into two groups, each with four participants in which the researcher acted as the facilitator for each group. Using this approach we observed that patients need a mobile phone-based system that minimise professional language barrier and support their participation in their healthcare.

Few Examples from our PD sessions

The System Overview

The figure below gives a system overview in its initial stages. The architecture comprises a mobile application interface to the server, running an apache web server and storing health records on MySQL database. Furthermore, it also interacts with a web server that is maintained by the hospital. The web server supports read access to a patient’s health records. Patients are authenticated via Personal Identification Number (PIN) to the web service to retrieve their health records.

System Evaluation

System evaluation was conducted both in the laboratory settings and field study. Laboratory evaluation sessions included computational performance evaluation, Heuristic Evaluation, user experience evaluation and focus group evaluation.

Field Study
The next phase of the project is to deploy the system at the health centre. This will enable the investigator to evaluate how users think about the system, interact and integrate the system within the settings they will ultimately be used in.
