The document discusses developing a movie recommender system. It conducted interviews with 3 users - an accounting student, film studies student, and blogger - to understand their needs. Empathy maps were created to understand what each user says, thinks, feels and does. The main needs identified were for the accounting student to quickly find new movie recommendations based on recently watched movies. The film student wanted easy to use recommendations by genre and randomly. The blogger wanted a simple interface that recommends randomly and by genre. The document proposes how to design the layout according to user needs, ensure movies are always new recommendations, and create a user friendly GUI.

2. THEME SELECTION
• Recommender system
• A recommender system or a recommendation system is a subclass of information
filtering system that seeks to predict the "rating" or "preference" a user would give
to an item. They are primarily used in commercial applications.

3. INTERVIEW
Here is our interview. We used this to gather
information. We asked a variety of users and
asked them questions. The questions related to
the empathy map and had questions in regards
to how the user says, thinks, does and feels.
This then allowed us to break the data down.

4. RESPONSES
• We interviewed a variety of different users. The users are as follow:
• User 1 (Final Year Accounting Student)
• User 2 (Film Studies Student)
• User 3 (Blogger)
The purpose of asking a variety of different user was because we wanted to get a variety
of answers. This will then allow us to find different needs that cater for a variety of
audiences.

7. POV – POINT OF VIEW
User Need Insight
Final year accountant
student
To be able to find new movies
to watch based on their
recently views
The user wants quick access to movies which are based off their recently viewed. The user would like a system which
allows them to search easily and random movie shuffle. The user had an unpleasant experience as she feels
recommender systems can be bias. It is important to her that critics’ reviews are an option to see before watching a
movie. It is important for the user that they find good movies in a short amount of time.
Film Studies Student To watch different movies and
refine them
The uses needs a movie recommender which is easy to use, can recommends movies based on the genre and
recommends randomly. It is important for the user that the layout is not messy and the movies have critics and
ratings stated with them. However, they want the recommender to recommend different movies every time. It is
important for the user that the recommender is actually helpful because it will aid them with their studies.
Blogger (Expert) To watch different movies
based on suggestions and use
the shuffle function
sometimes.
The user would like an interface that has multimedia which is easy to use that recommends randomly as well as
based on genres they watch. The layout should be simple and easy to navigate. The user also thinks that reviews.
The user also thinks that the popularity of a movie should affect where it stands when it is recommended to the end
user.

8. HMW – HOW MIGHT WE
3 main points
• How might we make the layout according to the needs of the users?
Prototype different layouts and get feedback from users, and then decide which one is the
best suited and preferred from the majority of the users.
• How might be make recommender systems always recommend a new movie?
Add a function which allows them users to mark a movie as “seen” and a “not interested”
which allows the UI to understand that the user has already seen that movie
• How might we make the GUI user friendly?
Ease of access, help button, and search bar, favourite movies, option to zoom in and out,
create a watch list
