  This survey presents recent progress on Affective Computing (AC) using mobile
devices. AC has been one of the most active research topics for decades. The
primary limitation of traditional AC research refers to as impermeable
emotions. This criticism is prominent when emotions are investigated outside
social contexts. It is problematic because some emotions are directed at other
people and arise from interactions with them. The development of smart mobile
wearable devices (e.g., Apple Watch, Google Glass, iPhone, Fitbit) enables the
wild and natural study for AC in the aspect of computer science. This survey
emphasizes the AC study and system using smart wearable devices. Various
models, methodologies and systems are discussed in order to examine the state
of the art. Finally, we discuss remaining challenges and future works.
