FRBS we employed, along with the
fuzzified
input
parameters, is shown in Figure 10.
Whilst a number of parameters such as light
and temperature measurement have been simu-
lated at this stage, the implementation of live
sensor data from such devices is a trivial one and
is only limited by the current lack of the hardware
resources to incorporate these devices into the
live system.
In its current state the system demonstrates
the ability to read contextual data from the user
and correlate this with information from the en-
vironment to make an informed judgement of the
user's emotional state. With future development
and also feedback from the user whilst using the
system, the facility will be available to teach the
playlist generator about the user's preferences
and train the accuracy with which the system is
able to estimate the emotional state of the user.
We have seen that awareness of the presented
issues is beneficial in not only providing richer
interactive experiences and more appropriate
information, but that knowledge of the purpose
of information can be used to optimise compu-
tational challenges. Furthermore, information,
such as that presented visually, can be analysed
in terms of content and context with the goal of
being able to stimulate emotions in a user who
might otherwise be disadvantaged from such an
experience, due to visual impairment.
It is hoped that we have demonstrated the ap-
plicability of determining and analysing features
related to emotion, content and context in relation
to improving systems where user-interaction is of
particular significance.
