t-learningTV-based interactive learning at home
Introduction
Now challanged by other media formsInteraractivity & mobility
New services to generate new TV forms able to attract and retain audiences
Investigate how to support authors in exploiting the t-learning potential

exploiting the t-learning potential
TV specific features
Several t-learning principles and applications inspired by e-learningTV medium’s specific features
Transmit information through broadcastingLimited computing hardware

Limited computing hardwareDifferent user interaction modalities�Remote control, low resolution screen, no
windows, no mouse, no keyboards
User typically in a relaxed environment and attitude
TV specific features
TV typically perceived as an entertainment mediumEmphasis on engagement and fun also for educational topics

Key t-learning peculiarities
Edutainment particularly suited for such a less formal learning environmentApplications

e-learning user-driven strategies�Applications respond to user actions
t-learning more suited to media-driven strategies for interactivity
Key t-learning peculiarities
A strong motivation for investigating how to exploit Serious Games’ principles on iTVA challenge on how to adapt the SG’s typically user interaction-driven philosophy to a media-driven environment
7
1st International Workshop on Serious Games Development & Applications
Univ. of Derby, 8 Jul. 2010
A number of educational games titles already exist for iTV
Simply exploit TV as a display/computation medium
We are interested in exploring the integration of SGs and TV programs
Sample existing applications

Enhancing educational TV programs
A lot of iTV research donePersonalization, interactive narrative and remote collaboration
Research should be done on how to support pedagogical experts to enhance
9
1st International Workshop on Serious Games Development & Applications
Univ. of Derby, 8 Jul. 2010
support pedagogical experts to enhance linear TV A/V streams
iTV educational services as enhancements aimed at giving more value to TV-specific languages and styles
Integrating TV & SG
Exploit and enhance the value of creative TV professionals
e.g. authors, scriptwriters, cartoonists, etc.
Allow viewing of a program by interactive and non interactive users
10
1st International Workshop on Serious Games Development & Applications
Univ. of Derby, 8 Jul. 2010
Foster a meaningful re-use of archives of TV programs and historical videosApproach complementary to techniques borrowed from e-learning
e.g. remote user collaboration
Further requirements from user/stakeholder analysis
Compatibility with other iTV platformsSupport for various categories of usersEfficient content productionSupport for User Generated Contents

(UGC)High-quality graphics and usability
The ELU format (high-level)
A linear A/V streamNo user control
Non-linear interactive contentsAvailable over the videoControllable by the user
12

Controllable by the user
Exploit a linear storyCan be viewed also by non-interactive users
Provide enhancements to improve the interactive user’s experience
The ELU format (high-level)

Communication is a very important part of a TV program
Careful support of multimedia design2 clusters of configuration parameters
Content, Style
Libraries of styles by 3rd party media designers

Conclusions
Design of a system architecture with specificmodules aimed at supporting serial instantiationof SGs applications in several different iTVcontexts
e.g. cards, game templates, ProgressBar, PerformanceMeter

PerformanceMeter
Visual authoring tool to support efficientproduction of the interactive elementsEvolutionary rather than revolutionary approach
A media-driven strategy and the role of the author/director in proposing contents
Conclusions
Added value of SG interactivityhelp the viewer to better contextualize/understand the video stream andgo more in depth about the touched items at the end
