  1. Engaging participants for collaborative sensing of human mobilityHelena Rodrigues, Maria JoãoNicolau, Rui José and Adriano MoreiraCentro Algoritmi, Universidade do Minho, Portugal 1st International Workshop on Ubiquitous Mobile Instrumentation, 8 September, 2012

  2. Outline • The problem • The Epi application • Preliminary results • Discussion

  3. The problem • How to collect data for human mobility analysis • Where do people spend more time during the day? • Which are the most frequent routes used by people? • It is possible to suggest alternative and more sustainable paths for daily trips • Which could be the best decisions concerning new computing infrastructures deployments? • Large data sets • Extended periods of time

  4. The Epi application • Explore people as sensors • Laptop vs mobile phone • Social application • Text messages sharing between users • Collects information about nearby APs • Privacy policy • Preserves normal spatio-temporal behaviour of users • Text messages sharing as a service reward • Non-personalised advertisements through social services (in July and October 2010) to attract users

  5. Preliminary results Web site: unique visitors per day Web site: number of downloads per day Application: number of active users per week. Collected data: number of records uploaded per week

  6. Discussion • Users are more active close to advertisement periods • Scalable solution for advertisement and distribution? • Improve users’ awareness about the value of the data collected collaboratively • Which should be the main characteristics of a mobile sensing application? • Open access/publication to/of the data • How to ensure privacy, trust and integrity?
