Data Types and Functionality

Shown here is table of core functions, the sensors/devices that the ORCATECH platform uses to measure these functions continuously, and the conventional assessments that are typically used to get a snapshot of the function.

Core Functions & ‘Digital’ Measures

Physical Activity: Total daily activity, number of room transitions, walking speed, daily steps, time out of home

Sleep/Nighttime Behavior: Time of awakening, time in bed, wake after sleep onset, times up at night, sleep latency

Physiologic Health: Daily BMI, pulse

Indoor Environment: Air quality, temperature, CO2, noise, light

Medication Adherence: Percent of doses missed in a week relative to prescribed schedule

Socialization: Time out of home, time alone or with spouse, online computer activity (email, social network sites), number of calls, number of texts

Cognitive Function: Time to complete online tasks (e.g., weekly health form), mouse movements, prospective memory for medication, AM weighing protocol

Mobility: Driving time, distance driving, hard braking, hard accelerations, frequent locations out of home

Health & Life Events: Weekly online self-reports, customized queries or standard scales

Care Partner Engagement: Time alone, time with patient
