Summary: Fostering intrinsic motivation with interactive applications can increase
the enjoyment that people experience when using technology, but can also
translate into more invested effort. We propose that identifying with an avatar
in a game will increase the intrinsic motivation of the player. We analyzed
data from 126 participants playing a custom endless runner game and show that
similarity identification, embodied identification, and wishful identification
increases autonomy, immersion, invested effort, enjoyment, and positive affect.
We also show that greater identification translates into motivated behaviour as
operationalized by the time that players spent in an unending version of the
infinite runner. Important for the design of games for entertainment and
serious purposes, we discuss how identification with an avatar can be
facilitated to cultivate intrinsic motivation within and beyond games.

Summary: Photo collages are a popular and powerful storytelling mechanism. They are
often enhanced with background artwork that sets the theme for the story.
However, layout algorithms for photo collage creation typically do not take
this artwork into account, which can result in collages where photos overlay
important artwork elements. To address this, we extend our previous Blocked
Recursive Image Composition (BRIC) method to allow any number of photos to be
automatically arranged around preexisting exclusion zones on a canvas (exBRIC).
We first generate candidate binary splitting trees to partition the canvas into
regions that accommodate both photos and exclusion zones. We use a Cassowary
constraint solver to ensure that the desired exclusion zones are not covered by
photos. Finally, photo areas, exclusion zones and layout symmetry are evaluated
to select the best candidate. This method provides flexible, dynamic and
integrated photo layout with background artwork.

Summary: The revolution in consumer electronics for capturing video has been followed
by an explosion of video content. However, meaningful consumption models of
such rich media for nonprofessional users are still emerging. In contrast to
those of video cameras, the consumption models for output of still cameras have
been long established and are considerably simpler. The output of a still
camera is an image of sufficiently high quality and high resolution for a good
quality production on paper. Due to ease of use, mobility, high quality and
simplicity paper photographs are still incomparable in terms of overall human
experience. On the other hand, video content by itself is not as easy to use.
Consumption of video content requires computers and/or video display devices
and so cannot be instantaneously displayed or shared. Rendition on paper is
much more complex for video content compared to still camera images. In
contrast with the simplicity of usage of still cameras, video camera output has
to be edited on computer, key frames with good visual quality have to be
manually extracted, digitally edited and prepared for printing before getting
usable good quality photographs. Due to complexity of the video content, users
often prefer to take still pictures instead of recording video clips. In this
paper we describe an approach to construct an end-to-end digital publishing
workflow system that automatically composes visually appealing photo albums
with high quality photographic images from video content input.
