Research Area

Almost all the talks given in this conference are closely related to mobility and locations.

• AI: A group of people, doing research about human activity recognition, have moved from AAAI to this conference, as the quality of AAAI has dropped down in recent years. In contrast to other attendees, they are more technical persons, who love to use data mining and machine learning algorithms, such as Markov model and topic model etc.
• CHI: Over one third of researchers are with CHI background. I think they are more conceptual persons, who pay more attentions to the computer human interaction in a ubiquitous environment.
• Ubiquitous Multimedia: This is a relatively novel research direction, which focuses on social media and multimedia sharing in a ubiquitous environment.
• Others: location-based service, Web privacy and security, context-aware computing, etc.
