In our current society which is characterized by mobility, individuality and comfort requirements, there is a need for real-time information and services that make people’s life easier. In Public Transportation (PT), such data is crucial for enhancing the travelling experience. Lately, the number of smartphone applications for trip planning, mobile ticketing and validation has grown considerably, but they do not take into account the user’s affective state or his Quality of Experience (QoE). Emotion, that is fundamental to the human experience influencing rational decision making, is rarely taken into account.
Thus, in this work we present a new solution to find and understand patterns of user satisfaction based on the collection of affective and context information with and without direct user input. The current growth of ubiquitous systems allows the use of everyday devices, specially smartphones, wireless sensors and wearable computers to smoothly collect multi-modal sensorial data during trips. While the user input serves as a solid validation of the information received. A PT mobile service then uses these preference profiles to suggest more comfortable routes according to the user likings through a smartphone application. This adds a new domain of personal preferences to the usual duration, cost and number of changes in the transportation choosing criteria.
In this work we present a mobile sensing platform based on the mobile application responsible for collection trip data and user input, and its communication with the reasoning system in the cloud - the Cloud2Bubble (C2B) framework.
