Digital Convergent Design Considerations for Interactive TV

1. Digital Convergent Design considerations
for Interactive Television

2. WARNING !
To be consistent with the theme
of the presentation. The movie clip
you are about to see was
intentionally shot using a mobile
phone … a great example of a
convergent device.
Please excuse the shaking quality
of the video … it's really not our
fault
f lt … merely a by-product of
l b d t f
convergence

each other - computer bits migrate merrily - and escape
from their traditional means of transmission …”
Stuart Brand

7. Convergence

9. “Although convergence has been a popular topic of
discussion within the field of HCI for more than a decade,
very little empirical data has been reported on the use of
converged solutions.”

Lyn Pemberton

13. Convergent Media Design
is a design strategy that focuses on identifying and providing
solutions to implications of convergent media systems and
p g y
the challenges of convergence.

15. Because of the subjective and qualitative
nature of “design” we felt it was important to introduce
certain concepts that constitute our framework for thinking
about design criteria.
This criterion we felt provided a good framework to interpret,
evaluate and present the data we have collected in a
consistent manner
manner.

16. Semiotic Design
Design as a form of communication between two actors (the
designer and user). This is an idea introduced by Clarisse de
Souza in her book “Semiotic Engineering and
Semiotic Engineering”
furtherpromoted and expanded upon by Don Norman in his
book “Psychology of Everyday Things”

17. Affordance
The designer can create clues that naturally guide
the user to “perceive-able action”

18. According to Norman there are also constraints: three basic
categories exist - physical logical and cultural
physical, logical,and cultural.
Physical constraints are closely tied to real affordances e.g.
it is impossible to move the cursor outside the screen.
screen
Logical constraints use reasoning to determine the
alternatives,
alternatives and are valuable in guiding behaviour
behaviour.
Finally, cultural constraints are conventions shared by a
cultural group e.g. Q
g p g QWERTY keyboard. y

19. In the context of convergent media design we introduce
another category that is a slight variation of a physical
constraint.
t i t
“Device constraints” we describe as the
technological limitations of a particular device in being
able to accommodate another medium not conventionally
associated with that device.
A device may be designed to challenge the technological
limitations of an intended medium but unable to adapt to
accommodate another medium so easily

20. Meta-Communication

21. As services attempt to traverse platforms seamlessly, implications and
design considerations will begin to surface. These implications will in
someway be associated to poor communication somewhere in the design
communication process and will be manifested i th system d ig
i ti d ill b if t d in the t design.
It is important that the convergent media designer narrows the gap
between the conceptual model of the system and the mental model of
p y
the user; while trading-off against constraints - functionality and usability.

23. The main aim of this research was to gain an understanding of people’s
perceptions, attitudes and behaviour towards
convergent media.

24. Data Collection Strategy
-Structured interview: (quantitative)
General Questions
Questions were focused to mobile phone,
internet and digital television technologies.
Specific questions
Demographics
15-20 min
-Field notes (qualitative)
-Incentives:
Incentives:
T-shirts
Sky Navigators for Sky users
(remote control)
-Pilot Test: 19 people

25. Demographics
g p
Population size: 89
(randomly selected from members of the general
public)
bli )
43% Female
57% Male
Population age range: 16-65 years old.

27. In order to determine the questions that needed to be asked,
the research aims were further broken down into three categories from
which question were constructed around.
1. Competitive/complementary category
2. Behaviour category
3.
3 Perception category

28. 1
Competitive/complementary category: This category surveyed
participants’ exposure to various media technologies and their
preference in using a convergent service.

30. -Many participants received digital TV as part of a Triple service
f
(telephone, internet and digital TV)
-Some participants prefer t perform i t
S ti i t f to f internet related activities on th
t l t d ti iti the
internet (where they have broadband/wireless access) and not through
their televisions.
-Some participants are reluctant to and just prefer to watch television,
ignoring these services.

Behaviour category:
This category surveyed the behaviour of participants.
It considered frequency of usage and the context of that usage.

interactive features on their TV.
There is a correlation between heavy TV users and interactive features as
45,5% of the heavy TV users use the interactive features of their TV.

Because: NO TV, NO Internet, NO Mobile Phone This slide is
based on actual
field notes

51. “Convergence is remediation under another
C
name, and the remediation is mutual: the
Internet refashions television even as television
refashions the I t
f hi th Internet”
t”
Bolter, J. & Grusin, R. 1999
This process of remediation described by Bolter and
p y
Grusin exposes the need for new design consider-ations
- convergent design considerations.

52. Convergent design should consider the medium
the service is converging towards. A service that
towards
has been designed for one medium then
transferred directly to another, particularly
between two platforms that offer different device
constraints and affordances, is likely to fail in the
design communication.

53. Convergent service must be designed to be intuitive to
understand, easy to use and valuable to the user.
User centred design is another important consideration for
good convergent design.
It becomes essential in this competitive environment to
match the potential users’ expectation with t e
atc t e pote t a use s e pectat o t the
functionality of the convergent system.

54. Understanding the mental models of the user specific to a particular
device and identifying transferable effective aspects of that mental
y g p
model in another device can help users to understand and potentially
accept the convergent services.
Promoting convergent features is also a part of convergent design
considerations.
Promotion can also be approached through the design process.

55. Branding is also very important to
consider as brand strategy and
communication are essential parts of
creating user experience.
“Physical branding then becomes a part of the drive for usability, as we try
to help the user answer questions about what the service offers, who is
offers
providing it, what its relationship is to a broadcast programme, who, if
anyone, is asking for payment andso on. In other words, clear branding may
help the user develop a clear mental model of the service, which will
enhance usability.”.
Pemberton & Fallahkhair
