Social Feedback Systems

For the past few years, we have been witnessing an explosion of services based on social ties between people, so-called social networking services. In particular, as of October 2012, Facebook, a prominent example of a social networking service, has more than one billion users. The users spend a significant fraction of their time on communicating and sharing content with their friends: other Facebook users they consider as social peers. In addition, Facebook can be used to reconnect with old friends or to organize events in the real world, to name just a few examples.

Looking at these possibilities offered by today's social networking services, we speculate that in the near future we will be using something we dubbed social feedback systems. To illustrate, let us observe that a social networking service essentially relies on maintaining and processing a digitized social network: a graph induced by the friend relation between the service users. The social network, combined with appropriate data mining algorithms, can be a foundation for a number of applications. Today, the combination is used, for instance, for recommending new friends and targeting advertisements. We envision, however, that in the future it can be employed to more directly influence the behavior of individuals and groups of people. More specifically, in our daily lives we will rely on social feedback systems: systems that combine (1) collecting social ties between people, (2) analyzing them, and (3) feeding the analytical results back to the society to activate particular individuals or groups.

Body Sensor Networks

To be effective, social feedback systems will have to meet the following two goals. First, they will have to seamlessly bridge our surrounding physical world with the digital world of the Internet. Since we operate in the physical world, lots of our social interactions are physical rather than just online. Consequently, a social feedback system, in addition to our online social interactions, will need to detect and collect interactions in the physical world. For example, the fact that we talked with a person for half an hour may be a good indication that the person should appear on our friend list. Second, any analyses and feedback such a system will provide will have to be timely. Since our interactions in the physical world are governed by time, any feedback we get is often relevant only during short time periods. For instance, information that a good friend we have not seen for a while is in the same shop as we is relevant only until we pass the counters.

A smart watch we use in our research For these reasons, social feedback systems will likely leverage novel technologies: body sensor networks. They are networks of tiny, wearable micro-computers that can communicate wirelessly and can sense various aspects of their host's environment. A well-known device of this type is an appropriately configured smartphone. Moreover, recently other “smart” gadgets are being announced, such as “smart” watches or glasses. Finally, a new class of smart devices has emerged and is gaining industrial interest – wireless sensor nodes – which are tinier and less obtrusive than anything before. It is thus not hard to imagine that in the future such nodes will be commonly embedded into apparel, everyday accessories, and surrounding physical objects. As such, they seem ideal for detecting real-world social interactions and providing appropriate feedback to the people wearing them.

Research Goals

Our project concentrates around the following question: How can we build social feedback systems using body sensor networks? To answer this question, we investigate novel technologies, algorithms, and their social relevance. I want to join...
