Summary: While we know that persuasive system design matters, we barely understand
when persuasive strategies work and why they only work in some cases. We
propose an approach to systematically understand and design for motivation, by
studying the fundamental building blocks of motivation, according to the theory
of planned behavior (TPB): attitude, subjective norm, and perceived control. We
quantitatively analyzed (N=643) the attitudes, beliefs, and values of mobile
fitness coach users with TPB. Capacity (i.e., perceived ability to exercise)
had the biggest effect on users' motivation. Using individual differences
theory, we identified three distinct user groups, namely followers, hedonists,
and achievers. With insights from semi-structured interviews (N=5) we derive
design implications finding that transformation videos that feature other
users' success stories as well as suggesting an appropriate workout can have
positive effects on perceived capacity. Practitioners and researchers can use
our theory-based mixed-method research design to better understand user
behavior in persuasive applications.

Summary: We present Photocation, a tangible photography education system that invites
people to explore and learn about the technical settings involved in a digital
single lens reflex (DSLR) camera. The basic DSLR camera elements such as
aperture, ISO and shutter speed are represented in tangible forms so that
people can physically manipulate and explore how these settings interact with
one another to produce different types of photographic expressions. A built-in
physical diorama further provides a controlled environment to test their
photographic settings against. By physically exploring with Photocation,
aspiring photographers can familiarize themselves with the interactive linkages
of the basic DSLR elements and take exemplary photos before transferring their
knowledge to full-fledged DSLR cameras. We present the design rationale, a
prototype, and a preliminary evaluation of our prototype.

Summary: The present paper introduces three facets of information overload in email
communication: A large amount of incoming information, inefficient workflow,
and deficient communication quality. In order to cope with these facets of
information overload, a training intervention was developed and evaluated. Data
were collected from 90 employees on several evaluation levels within a
longitudinal evaluation design (one pretest double posttest design). The
results reveal that the training contributed to an increase in knowledge and
media competencies. We also found evidence for a transfer of training contents
to the workplace. Finally, strain diminished on several dimensions. In
particular, problems with media usage and work impairment decline
significantly, an effect that was stronger for those participants who face a
large amount of email at their workplaces.
