  In this paper we present a prototype of a smart home system which can actuate
different peripherals based on the emotional "arousal" level of an user. The
system is comprised of two embedded subsystems named "Wearable" and "Benchtop"
which communicates with one another over UPD/IP protocol. The Wearable unit can
differentiate the emotional arousal into three distinct classes (Normal, Medium
and High) based on physiological data whilst the Benchtop unit can display
different colors on a 16 digit NEOPIXEL ring and, play tones to emulate
actuation of peripheral devices in the smart home environment. Experiments with
three video clips were performed which showed that the system can classify
emotional arousal with an average accuracy of 41%. An FSM model of the Benchtop
unit was created using Ptolemy II which showed the model to be fully
deterministic and robust to communication disruption between the two units. The
proposed project will add a new paradigm in smart home and IoT research by
incorporating emotional feedback to automatically adjust the indoor environment
for greater comfort, ease of living and in-home assisted ambulatory care for
the residents.
