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
