3. T307: description
With this thesis we investigate whether users can gain added value by using a
second screen application when watching a nature documentary on TV.
Design, develop and evaluate the impact on the user of (a) second screen
application(s).
Goal of this thesis

4. Research question / Problem definition
Goal of this thesis
Creating added value and increasing
the interaction without negatively
affecting the viewing experience.

6. Prototype 1
Main ideas
• Synchronization with a Planet Earth episode.
• Receive information-blocks while watching an
episode.
• The information should be related to what is
shown on the episode, but also unseen / new.
• Rewatch information-blocks from previously
watched episodes.
Recap

7. Prototype 1: V1
• Started out with
sketches on paper.
• Helped to decide which
features were (not)
useful.
Recap

8. Recap
Prototype 1: V2
• In an effort to make the evaluation a
more realistic experience for the
participants, InVision was used to
create a semi-digital prototype.
• Buttons
• Swipe & Touch
• Timed screen changes
• Viewable on a tablet
• For the same reason,
GIF animations were added.

9. Recap
Prototype 1: V2

12. Recap
Prototype 1: V3
• 100% digital prototype
• Native Android application
• Fully synchronized
• Few elements hard coded
• Data dynamically loaded and
displayed from database

16. Prototype 1: V2
Evaluation results
Evaluating the usability and usefulness was the main
goal of this evaluation.
5 participants: ranging from 20 to 23
years old.
Average SUS of 73: the lowest being
60, the highest 87,5

Feedback from last presentation
• Remark “And what about communicating
from the tablet to the TV?”
• Had me thinking
• What is typical for nature
documentaries?
• A new idea was born!

19. Prototype 2
Main ideas
• Fragmentize the documentary
• Let the user decide what he wants to see
• Increase control / interaction
• Instead of only consuming, allow “producing”
Progress

20. Progress
Prototype 2: V1
• Paper prototype
• 2 modes
• Mode 1“Live viewing mode”
• Documentary starts playing
• Different fragments are tracked
& shown
• User can skip to other fragments
• Mode 2 “Storyboard mode”
• User selects a set of fragments
(creates a storyboard)
• User plays the selected fragments

Evaluation results
Focus on usability. The participants were asked to
perform certain tasks which were described in a
scenario. Both modes were evaluated.
5 participants: ranging from 20 to 56
years old.

25. Progress
Prototype 2: V2
• Digital prototype
• “Storyboard” mode extended with functionality
of the “live viewing” mode
• Create a storyboard using multiple select
• TV-prototype

26. Progress
Prototype 2: V2
TV-prototype
Realistic setting for evaluation means more reliable
feedback
Creation of TV-prototype
• Amazon web services
• S3
• SNS
• SQS
• RTMP Streaming server (Cloudfront)
• JWplayer
• Javascript / AJAX
• PHP

27. Prototype 2: V2
Core functionalities
Select fragments in the order you want / create a
storyboard
Progress
Remove fragments from the storyboard
Play the created storyboard
Keep track of your selected fragments while your
storyboard is playing on TV
View which fragment of your storyboard is
currently playing
Fully synchronized with the TV-prototype

Prototype 2: V3
• More interaction, “means of control” required
• Implementing “TV-remote functionality”
• Required to update the second-screen
prototype as well as the TV-prototype

32. Prototype 2: V3
Core functionalities
Play / pause a fragment
Progress
Next / previous fragment
Configure, update your storyboard
Mute / unmute the audio
Adjust the volume
Complete synchronization between second-
screen prototype and TV-prototype

33. Prototype 2: V3
The control-bar
All new functionalities are
grouped inside the control-
bar
Progress

34. Prototype 2: V3
Evaluation results
The Main goal of this evaluation was to check the
usability, usefulness and aesthetic qualities of the
prototype and to check if the new functionalities
were well received.

35. Prototype 3
Main idea
• Combine the information-blocks from prototype 1
with the fragmentation & control functionality of
prototype 2.
• Consume & produce
Motivation
• Create an overall better application
• Eliminate problems with prototype 1
• E.g. distraction
