Summary: This paper describes a system for embodied conversational agents (ECAs)
developed at the University of Texas at El Paso by the Advanced aGent
ENgagement Team (AGENT) and one of the applications -- Survival on Jungle
Island -- built with this system. In the Jungle application, the ECA and a
human interact with speech and gesture for approximately 40 -- 60 minutes in a
game composed of 23 scenes (to maintain the demonstration feasible,
participants will interact only with select scenes that showcase the
capabilities of our system). Each scene comprises a collection of speech input,
speech output, gesture input, gesture output, scenery, triggers, and decision
points.

Summary: Our research seeks to provide embodied conversational agents (ECAs) with
behaviors that enable them to build and maintain rapport with human users. To
conduct this research, we need to build agents and systems that can maintain
high levels of engagement with humans over multiple interaction sessions. These
sessions can potentially extend to longer periods of time to examine long-term
effects of the virtual agent's behaviors. Our current ECA interacts with humans
in a game called "Survival on Jungle Island." Throughout this game, users
interact with our agent across several scenes. Each scene is composed of a
collection of speech input, speech output, gesture input, gesture output,
scenery, triggers, and decision points. Our prior system was developed with
procedural code, which did not lend itself to rapid extension to new game
scenes. So to enable effective authoring of the scenes for the "Jungle" game,
we adopted a declarative approach. We developed ECA middleware that parses,
interprets, and executes XML files that define the scenes. This paper presents
the XML coding scheme and its implementation and describes the functional
back-end enabled by the scene scripts.

Summary: Identifying the natural gestures for a tabletop application is one of the
most challenging tasks developers must accomplish in order to achieve a good
system user interface. This problem is even more difficult in a collaborative
environment. Cooperative Gestures allow richer interaction and must be
evaluated when designing a new multi-user tabletop interface. In this paper we
present the use of paper prototyping to analyze user interaction on a tabletop
collaborative game application. Our results show that it is possible to extract
natural gestures for an application using this technique, regardless of some
limitations.

Summary: We present an interface for navigating digital collections based on a
one-dimensional analog control and a data visualization based on old analog
radios. Our system takes advantage of inertial control to browse a large data
collection in a compelling way, reducing the complexity of similar interfaces
present in both desktop-based and portable media players. This vintage radio
interface has been used to navigate a digital music collection. We have
compared the proposed interface with the current most popular hardware, the
iPod. The results of user tests with 24 participants are presented and
discussed. The insights gained are encouraging enough to continue the
development of one-dimensional analog controls for content discovery and
retrieval.

Summary: In this paper we present a natural interaction system that simulates an
interactive mirror behavior where a subject or object can appreciate in real
time the effects of external agents over themselves and the causes or actions
that trigger these effects. It is a low cost system and easy to use,
personalize and configure, which makes it extensible to different operating
sectors, especially on the education area for interactive demonstrations. The
system does not use marks and realize the detection and projection of effects
in real time. For the system development a technology was invented and
developed that originated the patent request ES200901210.

Summary: Sistemas de Informação em Saú;de são
extremamente complexos por serem de natureza confidencial, pelo volume
crescente de dados armazenados e por permitirem acesso a um grande
número de usuários distintos. Conseqüentemente, o desenho de
efetivas interfaces para esses sistemas tornou-se um importante desafio no
âmbito da Informática Médica. Entretanto, verifica-se que
pesquisas voltadas à construção de sistemas médicos
baseados nos princípios de desenho centrado no usuário (DCU),
visando sua usabilidade, tem tido pouca proeminência, especialmente no
Brasil. Reunindo esforços para modificar essa realidade, apresenta-se o
desenho da interface de um sistema de transmissão e arquivamento de
imagens médicas (PACS), o qual possui a interface WEB fundamentada na
área de Interação Humano-Computador (IHC), e seu desenho
norteado por heurísticas de usabilidade vastamente conhecidas na
literatura.

Summary: This paper presents a telerehabilitation system for kinesthetic therapy
(treatment of patients with arm motion coordination disorders). Patients can
receive therapy while being immersed in a virtual environment (VE) with haptic
feedback. Our system is based on a Haptic Workstation that provides
force-feedback on the upper limbs. One of our main contributions is the use of
a handheld device as the main interface for the therapist. The handheld allows
for monitoring, adapting and designing exercises in real-time (dynamic VE).
Visual contact with the patient is kept by means of a webcam.
