Some IoT system projects in our lab
Timed Up and Go @ Home
Ø Timed Up and Go (TUG) Testq 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

Can we do TUG @ home with more measurements?
Smartwatch TUG systemsØ A cloud-based Smartwatch TUG system
q Send reminders to the subjectsq 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

Raw Motion data
Smartwatch TUG System ArchitectureØ 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 Alexaq 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 & actuatorq Smartwatch, Raspberry Pi (with Camera, mic), motion sensors…
q Stepping motor, Light bulb, A/C
Ø Connectionq AWS IoT…
• You don’t need to use AWS IoT, but you need to connect your devices to other devices or cloud.
Ø Smartq AWS Machine learning
• Analyze the big data from the sensors, then make a smart decision
