FEEDBACK LOOPS (HUMANS)

CYBERNETIC FEEDBACK LOOPS

WHAT IS A
CYBERNETIC FEEDBACK LOOP?

CYBERNETIC FEEDBACK LOOPS

FEEDBACK LOOPS (HABITS) FOR COMPUTERS

INTERNET OF THINGS

SENSOR = CUE

5 SENSES

HEAR

SEE

SMELL

TASTE

FEEL

HOW MANY HUMAN SENSES DOES A SMARTPHONE HAVE?

1. 2
2. 3
3. 4
4. 5

SENSORS SMARTPHONE

CAMERA = SEE

MIC = HEAR

TOUCH SCREEN = FEEL

GYRO / GPS = MOVEMENT

THEMOMETER = TEMPERATURE

SENSOR VALUES

0 = OFF

1 = ON

[ Sensor Values may vary based on sensor readings. ]

INTERPRETER = ROUTINE

IF CUE IS THIS

[ IF SENSOR VALUE = 0 ]

THEN DO THAT

[ SET POWER = OFF ]

........

IF THIS THAN THAT

INTERPRETER = ROUTINE

IF CUE IS THIS

[ IF SENSOR VALUE = 0 ]

THEN DO THAT

[ SET POWER = OFF ]

OR

IF CUE IS THIS

[ IF SENSOR VALUE = 1 ]

THEN DO THAT

[ SET POWER = ON ]

ACTIVATOR = REWARD

THE ACTIVATOR IS THE ENGINE OR MACHINE WHICH IS BEING CHANGED.

POWER TO THE LIGHT 

GOES ON OR OFF.

3. EYE MOVEMENT
4. COLORS

WHICH ROUTINE [PRGOGRAM]
IS BEING USED?

1. IF EYE MOVEMENT = 0, CONTINUE CLOCK
2. IF EYE MOVEMENT = 0, STOP CLOCK
3. IF EYE MOVEMENT = 1, CONTINUE CLOCK
4. IF EYE MOVEMENT = 1, STOP CLOCK

WHAT IS THE NEW CUE?

1. SEEING THE ESCALATOR

SMART FRIDGE PITCH

WHAT CYBERNETIC FEEDBACK LOOP COULD WE MAKE FOR A REFRIDGERATOR WITH SENSORS?

CAMERA, MIC, THERMOMETER, TOUCHPAD

SMART FRIDGE PITCH

HOW COULD WE USE A SMART FRIDGE TO HELP GOOD EATING HABITS? 

COMBINE FEEDBACK LOOPS AND CYBERNETIC FEEDBACK LOOPS TOGETHER.

TEAMS OF 2-3

PITCH IDEAS AT END OF CLASS.

NEW IDEA PITCH

WHAT'S THE HABIT?

LIST: NAME - CUE - ROUTINE - REWARD

HOW DO YOU PROGRAM THAT?

LIST:

[ CUE ] THE SENSOR USED?

[ ROUTINE ] IF WHAT THEN WHAT?
