Summary: Differently of the Web Accessibility Guidelines, which are already
consolidated as a reference, the initiatives to develop guidelines for
accessible mobile applications are recent and several approaches present only
suggestions rather than a concrete list of functional requirements. This work
analyzed 247 scientific articles to identify requirements that are being
considered to different types of impairments. The collected information was
consolidated and classified according to groups of impairments. As result, this
paper presents the main points of a checklist proposal for functional
requirements, which should be considered by mobile applications to ensure
accessibility with usability.

Summary: To assess the success of fall-prevention oriented exergames two digital
games were developed taking advantage of the Wii Balance Board (WBB)
capabilities. The objective was to evaluate the exergames' potential to address
elderly adults' declining motivation to exercise regularly despite the benefits
related to fall-prevention. The system uses the WBB to keep track of the
player's center of pressure and computes important balance assessment measures
related to it to eventually provide a mean to monitor their patients. The
presented demo will feature the two exergames.

Summary: Traditional recommendation systems use multiple computational techniques to
perform personalized recommendations, and can consider the interests of users
and even the context in which they live. However, they usually ignore each
individual's personality factors, and hence, the recommendations generated
overwhelmingly consider that all the users are identical psychologically. They
ignore, for example, the curiosity level of each user, which may indicate that
individuals with a high level of curiosity seek visit exotic locations and/or
not yet visited by them, or even individuals with a low curiosity level tend to
do the same things they did in the past, uninterested in new or different
areas. Our paper presents a complete hybrid recommendation system considering
the curiosity level of each individual as a decisive factor to recommend sites
of South America. In order to prove the efficiency of our system in contrast to
traditional recommendation systems, as well as to measure the satisfaction of
users about the recommendations, we performed some preliminary experiments with
the participation of 105 Brazilian volunteers. The first results indicate that
considering the level of curiosity of a user increases the satisfaction with
the recommendations.

Summary: This paper presents an interactive video system that enables users to change
the flow of video playback by interacting with hotspots that were predefined
throughout the video streams. These hotspots are synchronized with the
underlying video streams and the interactions result in smooth transitions
between the preloaded targets. This approach allows the dynamic visualization
of content by interacting with the hotspots and producing the consequent
changes in the flow of the story. The system includes web-based and mobile
video players specifically developed to deal with the interactive features, as
well as a configuration tool that allows content managers to choose which
pre-produced interaction possibilities will be used for a specific target
audience. The interactive video solution presented herein has potential to be
used as a powerful communication tool, in commercial, e-learning, accessibility
and entertainment contexts.

Summary: Human activity is very dynamic and subtle, and most physical environments
are also highly dynamic and support a vast range of social practices that do
not map directly into any immediate ubiquitous computing functionally.
Identifying what is valuable to people is very hard and obviously leads to
great uncertainty regarding the type of support needed and the type of
resources needed to create such support. We have addressed the issues of system
development through the adoption of a Crowdsourced software development model
[13]. We have designed and developed Anywhere places, an open and flexible
system support infrastructure for Ubiquitous Computing that is based on a
balanced combination between global services and applications and situated
devices. Evaluation, however, is still an open problem. The characteristics of
ubiquitous computing environments make their evaluation very complex: there are
no globally accepted metrics and it is very difficult to evaluate large-scale
and long-term environments in real contexts. In this paper, we describe a first
proposal of an hybrid 3D simulated prototype of Anywhere places that combines
simulated and real components to generate a mixed reality which can be used to
assess the envisaged ubiquitous computing environments [17].

Summary: uCom enables remote users to be visually aware of each other using "spatial
displays"' live views of a remote space assembled according to an estimate of
the remote space's layout. Remote video views from multiple viewpoints are
shown individually or in a 3D collage representation that is faithful to the
scene geometry. A multi-display setup integrates always-on visual connections
of a remote site into the local space. This work applies an innovative spatial
context to visual awareness between remote locations.

Summary: In this paper, we present the use of hypertree as a supporting tool for
visualization of ontologies in agricultural domain. This kind of visualization
technique was used in the Information Agency Project, in execution by the
Brazilian Agricultural Research Corporation -- Embrapa. The project's aim is to
provide an information dissemination system structured in accordance to the
productive chains of given products. That structure was chosen because it
reflects the natural way technicians use to interact whenever they are
transferring knowledge back and forth with farmers.
