We developed Tiramisu, a mobile transit information service, during a project investigating how social-mobile computing might support the co-design of public services by the citizens that use these services. Released publically in 2011, this service allows transit riders to co-produce a real-time arrival information service by sharing location traces from their smart phones. The service is used by thousands of commuters each month, and over the last several years it has become an unexpected platform for research in the real world. Our team has used the service to probe on user contribution; we analyzed logs to assess the impact of new features; data mining to discover information that both helps transit planners and has aided is in envisioning many new smart services. In this talk I will share the story of Tiramisu’s design, how it has become a research platform, and lessoned learned from trying to keep a deployed research prototype running.
This lecture is open to the PolyU community only. Because of limited seats, priorities will be given to staff, students and alumni of SD when registrations for this lecture exceed its capacity.
