3. quality of the environment, computed from average lighting, humidity and temperature; 4. Body Mass Index (BMI) value.
The evaluation of items at the state level can depend on specific input from caregivers.

Functionalities Items in this class include disabilities in the following aspects of the person's health state:

1. *balance* and *gait*, initially evaluated through the Tinetti-POMA (Tinetti et al. 2002) medical scale; indicators are represented by i) assessment of related pathologies, ii) drug intake and iii) indicators representing a few aspects of the scale that can be captured by the wearable sensor and evaluated through ad-hoc feature aggregation: standing, sitting, laying, turning and walking; 2. *nutrition*, initially evaluated by means of the Mini Nutritional Assessment (Guigoz et al. 1994) test; the indicator is the Body Mass Index (BMI),
stored every hour; 3. *vision*, initially evaluated through specific tests; indicators are the average
