Welcome
People Prototypes Privacy
Please let me introduce somepeople from my past
People
Differing interestsOne size doesn’t fit all
Human
Prototyping
Remember the people while developing the prototype
People centered design
– Touch• Gentle• Soft
– Sound• Music• Familiar voices
– Vision• falling• disorienting
Select your hardwarefor proof of concept first
– Sensors– Brain – Communications
Prototyping time has rapidly accelerated.It’s not unusual for a prototype to be created in several weeks.
Longer to mass production.
Sensors for movement and activity
• MEMS Accelerometers – position in1, 2, or 3 directions– Analog Devices ADXL362
• Gyro – rotation– Invensense ITG-3xxxx
• Magnetometer– Honeywell HMC5833L (3-axis digital compass IC)
• Pressure and Altitude – Measure small movements – Freescale MPL31152

Sensor Fusion
• Makes prototyping easier by bundling sensors in one IC or board
• Monitor movement as the individual sensors
Example: Invensense MPU-9150, Sparkfun $35Hillcrest Labs Freespace FSM-9 (state of the art)

Choose software for ease of development
–Modify easily–Modular, reusable code blocks– Arduino IDE– C– Python
Choice: Firmware or Operating System
• Do your need 3rd party developers?
• Do you need multiprocessing?
• If no, firmware should be fine (Arduino)
• If yes, OS like Android, Linux, QNX, TinyOS

Consider cases for useover a distance
Going beyond just a single user in their immediate environment
–Web or monitoring– Communicate with others in area– Android Wear
After proof of concept,iterate as needed
• Hardware– Cost– Power– Real estate
• Software– Best practices– API–Web applications
Privacy
ConsiderationProvide options
Be mindful when developing
• Camera – visual indicator on or off• Data– Ability to turn on or off data collection– user control, opt out– Level of trust
• “Big brother” employee interaction and activity monitoring
• Legal – HIPAA
What are you wearing?
• Questions• Ideas for brainstorming
Thank you
