System and Method for the Inference of Activities of Daily Living and Instrumental Activities of Daily Living Automatically
First Claim
1. A method to automatically derive answers to the questions of two clinical functional assessment instruments activities of daily living (ADLs), and all but one of the instrumental activities of daily living (IADLs) relying on sensors targeting the side-effects of the activities, said method comprising:
- date and time stamping sensor firings; and
setting a set of rules method where the spatio-temporal relationships of sensor firings are examined and analyzed to infer the occurrence of activities of interest, wherein said rules include at least one of the following;
a rule to automatically bathing/showering,a rule to automatically detect dressing,a rule to automatically detect toileting events,a rule to automatically detect the ability to ambulate (get out of bed/chair),a rule to automatically detect problems in controlling bladder and/or bowels,a rule to automatically detect the ability to feed oneself,a rule to automatically detect the ability to get to places outside of walking distance,a rule to automatically detect the ability to shop for groceries,a rule to automatically detect the ability to prepare meals, anda rule to automatically detect the ability to do house work.

Abstract
A method and related system to, among other things, automatically infer answers to all of the ADL questions and the first four questions of the IADL in the home. The inference methods detect the relevant activities unobtrusively, continuously, accurately, objectively, quantifiably and without relying on the patient'"'"'s own memory (which may be fading due to aging or an existing health condition, such as Traumatic Brain Injury (TBI)) or on a caregiver'"'"'s subjective report. The methods rely on the judicious placement of a number of sensors in the subject'"'"'s place of residence, including motion detection sensors in every room, the decomposition of each relevant activity into the sub-tasks involved, identification of additional sensors required to detect the relevant sub-tasks and spatial-temporal conditions between the signals of sensors to formulate the rules that will detect the occurrence of the specific activities of interest.
