CONTINUES COGNITIVE AND VITAL SIGNS MONITOR

Design Review

Problem Description

Elderly people who live alone face a unique set of problems Increased risk of falling and not being able

to call for help Deteriorating physical and cognitive state

due to lack of activity and stimulation Deteriorating sleep quality

Problem Description

Family members and caregivers often cannot address these issues due to various reasons It may be impossible to assign a caregiver

24/7 Physical distance Lack of information Lack of time

Proposed Solution

Continues Cognitive and Vital Signs Monitor will provide the elderly people’s family members and caregivers an up to date and comprehensive information on their well being

All the data will be available for viewing on a mobile interface and

Proposed Solution

An emergency detection system will identify falls and distress and notify a preconfigured list of caregivers that the user may need help automatically

Alert

Alert

Proposed Solution

Cognitive and vital signs monitor will keep track of the user’s sleep quality, physical activity levels and mental activity levels, and make this data available for family members and caregivers, thus enabling early diagnosis of various problems: Short or fragmented sleep Low levels of physical activity Low levels of cognitive stimulation

Proposed Solution

Caregivers will have the option to define additional alerts for: Wake up/sleep time Measurements rise above or drop below a

certain threshold Every reading will have an associated

GPS Coordinates to assist in locating disoriented users

Proposed Solution

Collected data: Drops detection (Accelerometer) Physical activity level and body position

(Accelerometer) Heart rate (Pulse Oximeter) Cognitive state and sleep time (EEG) GPS coordinates (Mobile phone GPS)

All the data but the GPS will be collected using a sensors belt and transmitted to the user’s mobile phone via Bluetooth

Competing Solutions

Distinguishing factors Fall detection, activity, cognitive and heart

rate measurements combined GPS readings for tracking a disoriented user Uses mobile phone for communication –

can be traveled with Does not require a designated call center

Users Characterization

Initial group of users: elderly people, their family members and caregivers

General group of users: people who are concerned with their well-being and personal safety

Financial Model

The users will need to purchase the sensors belt and a monthly subscription for the service
