Research interests

Computational sensing and user interface systems for preventive medicine, persuasive user interfaces for motivating behavior change, experimental ubiquitous computing, living laboratories, perceptually-based interactive environments for home and educational settings, dynamic scene understanding, context-based computer vision, artificial intelligence.

I am exploring how ideas from the fields of pattern recognition, machine learning, computer vision, and artificial intelligence can be integrated to develop algorithms that recognize the types of human activities that are common in everyday spaces such as educational environments, workplaces, and especially homes.  I am particularly interested in how robust algorithms can be developed that use statistical integration of contextual information when large training sets are not available. 

My group is exploring how computational sensing and AI techniques -- integrated with architectural principles and effective interface design -- can be used to create new types of living environments, learning environments, and entertainment spaces. A special focus is new algorithms that use ubiquitous sensing to recognize activities of daily living in order to determine when and how to provide preventive healthcare education in the home. As part of this work, we are developing context-aware algorithms and tools that both measure and motivate behavior change in real environments such as homes and public spaces. This work draws on ideas from computer science, behavioral science, social psychology, learning, and preventive medicine. We are creating computer systems that motivate healthy behavior over long time periods using both personal, handheld computing devices and next-generation ubiquitous computing environments.

Selected projects

	Portable In-Home Data Collection How can we easily instrument homes for doing research on ubiquitous computing and health technologies? We are building tools for in-home monitoring and developing datasets that can be used as a shared community resource. Essentially, we are creating a portable version a live-in multi-modal sensing system.
	User-Driven Pattern Recognition Most pattern recognition algorithms that detect activity and context from in-home or wearable sensors assume the recognition system is a black box. However, we have reason to believe this will not work in practice, and we are conducting research on how one might create inference algorithms where end-users play a key role in sensor installation, sensor maintenance, algorithm training, and error correction.
	Operant Conditioning for Motivating Behavior Change See: Mobile Health Project
	The PlaceLab How can ubiquitous computing technologies be created and evaluated that work for extended periods of time? How an persuasive interfaces designed to motivate behavior change in the home be studied in context? My research group, in collaboration with our partner TIAX, has developed the PlaceLab - an apartment-scale shared research facility in a residential condominium building in Cambridge where new technologies and design concepts can be tested and evaluated in the context of everyday living.
	MITes (portable sensors) The House_n group has developed a kit of wireless portable sensors that can be easily deployed in homes and offices for studying behavior and creating and evaluating novel context-sensitive human-computer interface systems. The sensors have been extensively tested (some in the PlaceLab), and they are being adopted by research groups other than House_n. They include sensors for measuring object motion, acceleration, current flow, heart rate, ultra-violet light, indoor position, and more.
	Computational perception and persuasive user interface design (multiple projects) Can computers with computational sensing motivate behavior change? In my lab we are working on several projects on using mobile and ubiquitous computers to both to measure and to motivate behavior change. This NIH, Robert Wood Johnson Foundation, and NSF-supported work is investigating the potential of computational perception for "just-in-time" information presentation and learning. We are studying intersection between new UI design strategies, computational tools for studying behavior change, computational learning algorithms for context-recognition and planning, and behavioral and social psychology.  A special focus is on the evaluation of the algorithms and devices we create in real environments. Much of the work deals with measuring and motivating physical activity and healthy eating.
	Context-aware experience sampling tools (multiple projects) How can we design tools for researchers in a variety of different fields that help them study people in real contexts? We are developing novel tools for mobile computing devices that can gather data for both computational and public health studies in actual home settings. These tools use variations on a technique we call context-aware experience sampling.
	Ubiquitous computing (multiple projects) In the House_n lab we have created a home-like pervasive computing environment with sensing systems and ubiquitous display and laser pointer interaction. We are investigating the implications of ubiquitous computing and computation sensing for motivating behavior change, particularly preventive health applications. I am particularly interested in the symbiotic relationship between architectural design, computational sensing design, AI, and user interface design. How will fusing ideas from these fields enable new devices and spaces that impact our lives in meaningful ways in the future?
	Recognizing multi-agent action (circa 1999) The goal of this research was to develop algorithms that integrate contextual domain knowledge and computer vision feature detection in order to interpret and describe events in sequences of video. In particular, the algorithms must handle scenes with multiple people interacting with each other. To demonstrate how this can be done, I designed a system that automatically labels actions and states in a football play such as "passing" "blocking" and "R34 run play" using probabilistic models.
	The KidsRoom (circa 1997) The KidsRoom was an interactive, narrative playspace for children. It was one of the first interactive environments to handle multiple people interacting with each other.  The actions of the children, who were in a real bedroom overlooked by several video cameras, were interpreted by computer vision tracking and action recognition algorithms. The story was used to establish context for the sensing algorithms enabling recognition of action, and recognition of action was used to create a new type of compelling interactive experience. A commercialized version of the system developed by NearLife for the British Millennium Dome won an interactive media design award from Id Magazine.
	Real-time tracking (circa 1997) This work, developed with Jim Davis, extended the idea of context-sensitive tracking to a real-time domain and was used extensively in the KidsRoom   Multiple objects are tracked in real-time from an overhead view.
	Context-based tracking (circa 1994) This work explored the use of contextual information for tracking tracking of multiple, interacting objects simultaneously.  The task was to automatically track football players in high-cam video of a football play. The low-resolution, colliding, blob-like players pose a problem for most conventional tracking algorithms, but knowledge about the rules of football and likely events in time can be used to resolve some tracking ambiguities.
	Large-occlusion stereo vision (circa 1993) Real stereo scenes with people typically contain large occluded regions. This work developed a computational stereo algorithm that is unaffected by the presence of large occlusion regions, permitting more accurate recovery of occlusion boundaries.
