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.
Слайд 11
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

Слайд 12
Sensor Fusion
Makes prototyping easier by bundling sensors in one IC or board
Monitor movement as the individual sensors
Example: Invensense MPU-9150, Sparkfun $35
Hillcrest Labs Freespace FSM-9 (state of the art)

Слайд 13
Choose software for ease of development
Modify easily
Modular, reusable code blocks
Arduino IDE
C
Python
Слайд 14
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

Слайд 15
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
Слайд 16
After proof of concept,iterate as needed

Слайд 17
Privacy
Consideration
Provide options
Слайд 18
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
