New publication: Location sharing services as sensors for analyzing airports’ traffic

Location sharing services can be seen as “social sensors” that provide data revealing real world interactions. In this paper, we examine the case of foursquare check-ins at airports and we show that these data can be indicative of the passengers’ traffic, while their number is hundreds of times lower than the number of actual traffic observations.

Materials from "Designing Human-Centred Pervasive Systems" - Summer School in cooperation with BEST (University of Patras Chapter)

BEST Patras Summer Course 2014 took place in Patras, Greece on 13-23th of July. Together with the students running the local BEST chapter, we organised this summer course involving 24 students from all over Europe. The purpose was to provide an introduction to Ubiquitous Computing and teach the students the process of converting an idea for a mobile app, to a design that can be tested with real participants.

Here you can find attached all the lecture and interactive session slides from the course. The topics are as follows:

New publication: Non-verbal Audio and Tactile Mobile Navigation - A comparative evaluation of two novel prototypes

As typical turn by turn systems fail in several aspects to provide an engaging experience to pedestrians in urban environments, we investigate the potential of alternative interaction methods for navigation. We present a two-phase experiment, involving both audio and tactile navigation and discuss the collected evaluation data. Our findings show a positive reception of implicit navigation from our users.

New publication: This is How We Roll: Cultural Traits in Check-in Behaviour

We describe our analysis of three months worth of collected human-physical environment interactions (foursquare check-in) data for two European cities: a medium-sized city in the Mediterranean and a larger city in North West Europe. Our analysis shows that though the data generated by the citizens is scarce (i.e. on average less than 15 users checked in at any time during the day), nevertheless they can closely reflect a city’s dynamics. The paper also discusses the strong suggestion of emergent cultural traits from the data and its use to power new pervasive applications based on human-physical interaction.
