Various embodiments of the di
sclosure relate to detection of emotional states
of a user. More specifically
, various embodiments of the di
sclosure relate to system and
method for providing recomm
endation on an electronic device
based on an emotional
state detection of a user.
BACKGROUND
[0003]
It is known that emotions
play an important role in
human life, and may result
in certain physiological and behavioral manifest
ations, such as a change in heartbeat or
facial expressions. Although attempts have been made to identify user's emotions,
existing systems may still lack the ability
to connect with a user emotionally or
empathetically. Existing systems that focus
on recommending relevant content to users
may hardly take into account changes in hum
an emotional states suited to practical use
by end consumers. Thus, an advanced system ma
y be required, where
such changes in
human emotional states may be
employed in an intelligent m
anner to provide emotion-
based recommendations with enh
anced practical usability.
[0004]
Further limitations and disadvantages
of conventional and traditional
approaches will become apparent to one of skill

DETAILED DESCRIPTION
[0014]
The following described im
plementations may be found in the disclosed
system and method to provide recommendation on an electronic device based on
emotional state detection of a
user. Exemplary aspects of t
he disclosure may include an
electronic device, which may detect a trans
ition in an emotional
state of a user
associated with the electronic dev
ice from a first emotional
state to a second emotional
state. A tagged content item a
ssociated with the second emot
ional state of the user may
4
be retrieved from a network device based on
identity information of the user and the
detected transition. An application may
be launched on the electronic device to
recommend a product or a service related to
the retrieved tagged content item. The
application may be launched in
response to the detected tr
ansition in the emotional
state of the user and a current lo
cation of the electronic device.
[0015]
In accordance with an embodiment, t
he first emotional state and the second
emotional state may correspond
to neutral, happy, sad, anger, contempt, fear, surprise,
confused, and tender. The network devic
e may correspond to a server, another
electronic device connected to the electron
ic device in a wireless home network, and/or
a cloud based service.
[0016]
In accordance with an embodiment, s
ensor data may be received from a

[0018]
In accordance with an exemplary aspect
of the disclosure, a transition in an
emotional state may be detect
ed for a user viewing a cont
ent item on the electronic
5
device from a first emotional state to a sec
ond emotional state. A
portion of the content
item viewed during the detec
ted transition may be associat
ed with the second emotional
state of the user. A cause of
the detected transition to t
he second emotional state may
be identified in the portion of
the content item associat
ed with the second emotional
state. A recommendation may be generated
for a product or service based on the
identified cause. The recommendation may
be generated in response to the detected
transition in the emotional state of the us
er and a current location of the electronic
device.
[0019]

16. A method for providing recommendation, said method comprising:
detecting, by one or more circuits
of an electronic device (102, 104), a
transition in an emotional
state (114) of a user (
112) associated with said
electronic device (102, 104) from a firs
t emotional state to
a second emotional
state;
retrieving, by said one or more circ
uits, a tagged content item associated
with said second emotional state of said
user (112) from a network device based
on identity information of said user
(112) and said detected transition; and
launching, by said one or more circui
ts, an application on
said electronic
device (102, 104) to recommend a product or
a service related to said retrieved
tagged content item, in response to said
detected transition in said emotional
state (114) of said user (112) and a curre
nt location of said electronic device
(102, 104).
17. The method as claimed in claim 16, further
comprising searching, by said one or
more circuits, said product or said servic
e based on said retrieved tagged content
item on said electronic device (102, 104).

18. The method as claimed in claim 16, fu
rther comprising dynamically customizing,
by said one or more circuits, a home scr
een interface of said electronic device
(102, 104) based on said detec
ted transition in said emot
ional state (114) of said
user (112) and a last tagged
content item associated wi
th said second emotional
state in said network device.
19. A method for providing recommendation, said method comprising:
detecting, by one or more circuits
of an electronic device (102, 104), a
transition in an emotional st
ate (114) of a user (112)
viewing a content item on
said electronic device (102, 104) from
a first emotional state to a second
emotional state;
associating, by said one or more circ
uits, a portion of said content item
viewed during said detected transition, with
said second emotio
nal state of said
user (112);
identifying, by said one or more ci
rcuits, a cause of said detected
transition to said second emotional state
in said portion of said content item
associated with said sec
ond emotional state; and
generating, by said one
or more circuits, a recommendation for a product
or service based on said i
dentified cause in response to said detected transition
in said emotional state (114) of said us
er (112) and a current location of said
electronic device (102, 104).
