Longitude

My group project in a User Interface Design and Evaluation class focused on the comparative evaluation of two mobile location sharing systems–Google Latitude and a research prototype Android app called Longitude. The main points of consideration were privacy, social pressures, and context-specific etiquette with friends, family, and workplace. The ultimate goal of this study was to prepare the two applications for a formal usability test.
The first task was to analyze the existing test scripts and user scenarios. From this analysis, we revised the scripts and began revising Longitude accordingly. We performed two rounds of pilot testing and continued an iterative revision process of the test scripts and location sharing app. Finally we presented usability-test-ready scripts and app along with a results analysis.
Our studies showed that people found the Longitude prototype more useful and more considerate of their privacy needs, which in turn caused them to feel that they would be more likely to use Longitude. Females were more interested in finding opportunities to meet up with people and both males and females over age 25 were more interested in meeting up with people they’ve been separated from as opposed to coordinating a pre-arranged meetup.
Our “client” was HCI PhD student Xinru Page. She created the project with guidance from Professor Alfred Kobsa and assistance from masters student Chung-yi Cho. My team members were Arjun Bhattacherjee, Jackie Doong, and Raminder Singh Goraya.
