Project Requirements & Methodology

Biosurveillance anaysts collected raw data (disease case counts and news articles) from multiple sources in order to monitor diseases globally. EpiEvident was a proof of concept application designed to improve the efficiency of the surveillance process by programmatically collecting the required standardized global disease case count data from different sources and visualizing it to support different analytical tasks.

Understanding User Needs

We interviewed 2 analysts and 3 stakeholders to identify our primary user, their goals and needs.

Identifying User Tasks

User Interface and Visualization Design

We explored several visualization options such as- Scatterplot View, Geo View & Matrix view. However, through multiple discussions with visualization and design experts, we decided to proceed with a combination of matrix view and a line chart.

Website Redesign

Georgia Tech Cable Network is a direct broadcast satellite system offering a customized channel line-up for the Georgia Tech campus community. GTCN supplies entertaining and educational television programs, offers video production services and plays movies chosen by GT students. Through GTCN’s Cinema Select voting system, students can pick their top choices from a series of available movies. The movies with the most votes are the ones selected to play on GTCN.

As a student web developer at Information Technology Group at Georgia Tech, I worked with GTCN to design and develop their “Movies” subsite using Microsoft Sharepoint 2010, HTML5/CSS3 and external plugins.

Users

While the consumers of the GTCN website are Georgia Tech students residing on campus, the site is maintained by the GTCN dept. This influenced the design decisions as the site needed to be responsive and easy to interact for the students on various devices, screen sizes and browsers but also being easy to maintain and update for the GTCN dept and student employees while being consistent with Georgia Tech brand guidelines.

Design Process

To improve the current design, I interviewed the GTCN webmaster and the student employees to understand the common issues and frustrations they faced. Google Analytics was then used to understand site visit and site flow trend which resulted in addition of the “Matinee” section on the movies landing page. The information was then used to rapidly prototype ideas using Powerpoint and the site was developed on Sharepoint using HTML5 and CSS3.
