Driving Smartphone
● Smartphone can be steered using IBM Watson speech
recognition
● The Watson sample app has been extended to send the text via
MQTT (Eclipse Paho JavaScript library) to the Bluemix Internet
of Things foundation
● A Node-RED flow is used to send commands to the native app
● When text is received from Watson
● When certain URLs are invoked
● When certain Twitter tweets are published
● The native Android app receives the commands and forwards
them to the ball

Personality Ball
● The Watson personality insights service is used to analyze the
personality of a person and detect the big 5 personality trait with
the highest value which triggers the ball to show another color
● Tweets are read via Twitter4J from a simple Java web
application. The same application invokes the Watson service
and sends the result to the Internet of Things foundation via
MQTT (Eclipse Paho Java library)
● A Node-RED flow receives the results and sends commands to
the native Android app which forwards them to the ball
