Timed Up and Go @ Home

Ø Timed Up and Go (TUG) Test

q A test of mobility and fall risk in community-dwelling, frail older

adults[1]

q Widely used in hospital

Test before surgery
Predict Falls

q Only measure the total time by the doctors

1/28/20 6

Can we do TUG @ home with more measurements?

SLIDE 7

Smartwatch TUG systems

Ø A cloud-based Smartwatch TUG system

q Send reminders to the subjects q Automatically collect and analyze the motion data q Doctors can see the results in real time.

TUG test Result

Ø The analysis is on cloud with AWS Lambda

1/28/20 8

Raw Motion data

SLIDE 9

Smartwatch TUG System Architecture

Ø Cloud based IoT system

q Sensing

Smartwatch motion sensors

q Connection

Auto upload the sensor data to AWS S3
S3 triggers an event to AWS Lambda

q Smart

AWS Lambda does the smart analysis
Give the feedback to the doctors

Alexa Voice-Agent for mental health

Ø A smart voice-agent based Amazon Alexa

q An “App” in Alexa is called as a skill q Guided Breath exercise to help soothe the patients

Mindfulness is reported to be able to relief stress[1]

Mindfulness Skill Architecture

Ø Echo device as frontend (Sensor and actuator)

q Get patients’ feelings; help the patient relaxed.

Ø Alexa Skill platform (Middleware) Ø AWS Lambda (Analysis)

q Build a database for each patient (AWS DynamoDB)

Recap: IoT concepts

Ø Sensor & actuator

q Smartwatch, Raspberry Pi (with Camera, mic), motion sensors… q Stepping motor, Light bulb, A/C

Ø Connection

q AWS IoT…

You don’t need to use AWS IoT, but you need to connect your

devices to other devices or cloud.

Ø Smart

q AWS Machine learning

Analyze the big data from the sensors, then make a smart decision
