The PlaceLab is a unique live-in
The PlaceLab was first introduced in a a CHI 2005 paper. This dataset is freely available for academic researchers to use in their own work given that this website (http://architecture.mit.edu/house_n/data/PlaceLab/PlaceLab.htm) is cited whenever the dataset is used, as well this academic overview article:

LNCS 3968, K. P. Fishkin, B. Schiele, P. Nixon, and A. Quigley, Eds. Berlin Heidelberg: Springer-Verlag, 2006, pp. 349-365. [Abstract] [PDF]
Researchers using the datasets should also indicate which of the public datasets they are using. The PLIA1 dataset is now a legacy dataset, because significant changes have since been made to the way that various data streams are shored, largely to facilitate better data sharing and visualization. The PLIA1 dataset does not work with the HandLense visualizer tool. The PLIA2 dataset uses current formats and works with the Handlense visualizer tool. We recommend that researchers interested in PlaceLab data use the PLIA2 dataset. We are leaving PLIA1 online because some work has already been published by groups outside of MIT that used it. These two datasets are test datasets to help researchers. There is a third dataset that has been released, PLCouple1, consiting of 100 hours of annotated data from a couple who lived in the PlaceLab.
A video of the PlaceLab is also available online and provides some general information as well as shots of the interior of the facility. The citation for the video is:

We have a new video that shows the sensor ubiquity and short latency times. It is in submission, but for an early preview, contact [intille at mit dot edu].
Some of the sensors in the PlaceLab are MITes. If data are used from them, please reference them using this publication:

Fishkin, B. Schiele, P. Nixon, and A. Quigley, Eds. Berlin Heidelberg: Springer-Verlag, 2006, pp. 117-134. [Abstract] [PDF]
In the PLCouple1 dataset, two additional sensors are included. The infrared MITes were developed as part of this work at MERL. If data are used from them, please reference them using this publication:

Munguia-Tapia, "Toward Scalable Activity Recognition for Sensor Networks," in Proceedings of The Second International Workshop in Location and Context-Awareness (LoCA '06), vol. 3987 / 2006, M. Hazas, J. Krumm, and T. Strang, Eds. Dublin, Ireland: Springer Berlin / Heidelberg, 2006, pp. 168-185.
The RFID tagging is provided using the Intel RFID glove. If data are used from them, please reference them using this publication:

As much as our resources allow, we are operating the PlaceLab as a shared research facility. In that spirit, we are trying to make some of the data from our experiments using the PlaceLab available to other researchers interested in designing novel technologies and devices for the home. The datasets may be of particular interest to researchers in pattern recognition, since annotated multi-modal sensor datasets from real homes are challenging to obtain at this time. We have a new project that will support creation of similar types of datasets using our portable in-home sensors. Stay tuned.
PLIA1 (PlaceLab Intensive Activity 1): The first test dataset we posted (and that is described in the PERVASIVE paper), is archived for those who still wish to use it. [Overview, description of data, and data]
PLIA2 (PlaceLab Intensive Activity 2): We have recently made extensive improvements to the PlaceLab infrastructure, including changing some of the formats in which data are saved to make data management and data sharing easier. These changes are reflected in the PLIA2 dataset. Researchers new to the PlaceLab should start with this test set and ignore the PLIA1 data. This dataset works with a visualization and annotation tool we have developed for PlaceLab data, called Handlense.

Due to subject privacy issues, it is not possible for us to release all the audio and video that was also collected for htis dataset. We also have not released transcrips from all subject interviews at this time. This dataset includes readings from the Intel RFID bracelet. Annotation is costly and we have only about 100 hours of the dataset annotated at this time. More may be annotated in the future. If you can help with that effort, please let us know. [Data]
We have collected other datasets from the PlaceLab and will continue to do so. We hope to make as many of those public as our resources allow. With the caveat that data that we share must be properly anonymized, we are interested in having as many other researchers benefit from the facility as possible.
If you review any of these datasets and you are interested in possibly using other datasets or working with MIT House_n researchers to conduct an original study in the PlaceLab (perhaps adding/testing new capabilities), then contact Stephen Intille ([lastname]@mit.edu). Further, contact Stephen if you have comments and suggestions on these test datasets, such as information that should be added to the documentation to make PlaceLab data easier to use, or if you have any resources you could volunteer (e.g., disk space) to make data sharing of larger datasets easier.
