11. Select your hardware
for 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.
12. 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

13. 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

14. Choose software for
ease of development
– Modify easily
– Modular, reusable code blocks
– Arduino IDE
– C
– Python
15. 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

16. Consider cases for use
over a distance
Going beyond just a single user in their
immediate environment
– Web or monitoring
– Communicate with others in area
– Android Wear
17. After proof of concept,
iterate as needed
• Hardware
– Cost
– Power
– Real estate
• Software
– Best practices
– API
– Web applications
19. 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
20. What are you wearing?
• Questions
• Ideas for brainstorming
Thank you
Editor's Notes
1980 – first ad – wear our music (34 yrs ago)
1970s Calculator watch – Lovely red LED, little pen, press the buttons, so cool – engineering
Steve Mann - “Wearable computer” Augmented reality evolved Iteration
More recently, EL wire, 3d printed case to hold the accelerometer and control and power
