The SPHERE project has developed a multi-modal sensor platform for health and
behavior monitoring in residential environments. So far, the SPHERE platform
has been deployed for data collection in approximately 50 homes for duration up
to one year. This technical document describes the format and the expected
content of the SPHERE dataset(s) under preparation. It includes a list of some
data quality problems (both known to exist in the dataset(s) and potential
ones), their workarounds, and other information important to people working
with the SPHERE data, software, and hardware. This document does not aim to be
an exhaustive descriptor of the SPHERE dataset(s); it also does not aim to
discuss or validate the potential scientific uses of the SPHERE data
