We focus on providing users with initial action, then try to maintain it. For
that, instead of relying on system recommendations, we introduce a human-expert in the process to
tune the activity when relevant. This will introduce simplicity in user-system
interaction, since it focuses on simple activities and follows "is able to do?" instead of "have to
do!" approach. We introduce a new interaction paradigm where user-coach interact through the
console. Based on common paradigm the coach provides standard personalised model specific
for each user.
Moreover, a human actor is more effective in overcoming limitations introduced by automation and
recommendation systems, since a human can better react to more
complex user needs and handle their emotions, that is hard to achieve with system automation.
In addition, the research focuses on addressing user heterogeneity problem in diet management
and investigates a tailored approach per user and a way to maintain the user coach relation.
This research addresses user heterogeneity and hybrid system challenges which often fail to react
to user needs. Based on the literature research, there is a need for a real coach, especially
when dealing with a sensitive issue, such as diet management. Since a human actor can provide
more precise emotional and health support and better understand user struggle. Virtual coaches
are effective in providing training sessions, however, they are unable to provide social support
that a real coach can. In addition, real coaches are flexible when dealing with various users.
More specifically, they can change the level of communication with people of different level of
preparedness, preferences and ages. In summary, unlike automated systems, real coaches can
communicate the language of the user.
This research focuses on designing for long-term feedback and engagement with the system.
Moreover, It takes an approach to involve users in their own health through
quantiffed-self techniques. There is a need to consider user's lifestyle and the role of technology
in their life. Also, consider personalisation in the diet management process. To illustrate, asking
users to record the food they don't like to avoid recommending them. The methodology focuses
on simplicity and positive reinforcement for future activities. The coach feedback is given by a
health expert who accesses and monitors user activities through a dashboard that contains user
