Proceedings of the 3rd IUI Workshop on Interacting with Smart Objects
These are the Proceedings of the 3rd IUI Workshop on Interacting with Smart Objects. Objects that we use in our everyday life are expanding their restricted interaction capabilities and provide functionalities that go far beyond their original functionality. They feature computing capabilities and are thus able to capture information, process and store it and interact with their environments, turning them into smart objects

Intelligent techniques for context-aware systems
Nowadays, with advances in communication technologies, researches are focused in the fields
of designing new devices with increasing capabilities, implanting software frameworks or middleware
to make these devices interoperable. Building better human interfaces is a challenging
task and the adoption of Artificial Intelligence (AI) techniques to the process help associating
semantic meaning to devices which makes possible the gesture recognition and voice
recognition.
This thesis is mainly concerned with the open problem in context-aware systems: the
evaluation of these systems in Ambient Intelligence (AmI) environments. With regard to this
issue, we argue that due to highly dynamic properties of the AmI environments, it should
exist a methodology for evaluating these systems taking into account the type of scenarios.
However in order to support with a solid ground for that discussion, some elements are to
be discussed as well. In particular, we:
• use a commercial platform that allows us to design and manage the contextual information
of context- aware systems by means of a context manager included in the
architecture;
• analyze the formal representation of this contextual information by means of a knowledge
based system (KBS);
• discuss the possible methodologies to be used for modelling knowledge in KBS and our
approach;
• give reasons why intelligent agents is a valid technique to be applied to systems in AmI
environments;
• propose a generic multi-agent system (MAS) architecture that can be applied to a
large class of envisaged AmI applications;
• propose a multimodal user interface and its integration with our MAS;
• propose an evaluation methodology for context-aware systems in AmI scenarios.
The formulation of the above mentioned elements became necessary as this thesis was
developed. The lack of an evaluation methodology for context-aware systems in AmI environments,
where so many issues to be covered, took us to the main objective of this thesis.
In this regard:
• we provide an updated and exhaustive state-of-the-art of this matter;
• examine the properties and characteristics of AmI scenarios;
• put forward an evaluation methodology and experimentally test our methodology in
AmI scenarios. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------La Inteligencia Ambiental y los entornos inteligentes hacen hincapié en una mayor facilidad
de uso, soporte de servicios más eficientes, el apoderamiento de los usuarios, y el apoyo
a las interacciones humanas. En esta visión, las personas estarán rodeadas de interfaces
inteligentes e intuitivas incrustados en objetos cotidianos que nos rodean y los sistemas
desarrollados para este ambiente deberán reconocer y responder a la presencia de individuos
de una manera invisible y transparente a ellos. Esta tesis se centra principalmente en el
problema abierto en los sistemas sensibles al contexto: la evaluación de estos sistemas en los
entornos de Inteligencia Ambiental. Con respecto a este tema, se argumenta que debido a las
propiedades altamente dinámica de los entornos de inteligencia ambiental, deberÃa existir una
metodologÃa para la evaluación de estos sistemas, teniendo en cuenta el tipo de escenarios.
Sin embargo, con el fin de apoyar con una base sólida para la discusión, algunos elementos
deben ser discutidos también. En particular, nosotros:
• Usamos una plataforma comercial que nos permite diseñar y gestionar la información
contextual de los sistemas sensibles al contexto a través de un gestor de contexto
incluido en la arquitectura;
• Analizamos la representación formal de esta información contextual a través de un
sistema basado en el conocimiento (SBC);
• Discutimos las posibles metodologÃas que se utilizarán para el modelado del conocimiento
en SBC y nuestra aproximación y propuesta;
• Discutimos las razones del por qué los agentes inteligentes son una técnica válida para
ser aplicada a los sistemas en entornos inteligencia ambiental;
• Proponemos un sistema multi-agente (SMA), con una arquitectura genérica que se
puede aplicar a una gran clase de aplicaciones de inteligencia ambiental;
• Proponemos una interfaz de usuario multimodales y su integración con nuestro SMA; • Proponemos una metodologÃa de evaluación de los sistemas sensibles al contexto en los escenarios de inteligencia ambiental.
La formulación de los elementos antes mencionados se hizo necesaria en la medida que
esta tesis se ha desarrollado. La falta de una metodologÃa de evaluación de los sistemas
sensibles al contexto en entornos de inteligencia ambiental, donde existen tantos temas a
tratar, nos llevó al objetivo principal de esta tesis. En este sentido, en esta tesis:
• Proporcionamos un estado del arte actualizado y exhaustivo de este asunto;
• Examinamos las propiedades y caracterÃsticas de los escenarios de inteligencia ambiental;
• Proponemos una metodologÃa de evaluación para este tipo de sistemas y experimentalmente
probamos nuestra metodologÃa en diversos escenarios de inteligencia ambiental

Universal Communication model and evaluation with the Elderly Society
Telecommunication uses today various devices, operating systems, network
technologies and applications. The multiplicity and diversity of these items are expected
to increase due to the development of new technologies. As a result communication
becomes a challenge. Communication is according to the World Health Organization a
basic requirement for participation of elderly people in the society. In this thesis the
architecture model ¿Universal Communication Model¿ (UCM) for the unified application
of these items is developed and investigated. The future society will merely be 60+ and
lowered physical abilities for communication need to be compensated. Two hypotheses
that represent challenges of the UCM are provided and investigated: First, ¿Elderlies have
difficulties in stress and ad-hoc situations to cope with ICT solutions¿ (H 1), and second
¿Elderlies have problems to reach destinations¿ (H 2). Both hypotheses are divided into
sub-hypotheses without and with UCM support.
Two use cases are applied to the UCM: Elderly father at home called by his daughter
from her car, and disoriented grandma walking to her appointment at the medical clinic
using the public transportation system.
The two use cases are detailed with scenarios and corresponding prototypes. 24
tasks for elderly probands are developed and executed in a laboratory setting with 30
elderlies (including a questionnaire): Half of the tasks, namely twelve, are designed
without the UCM and the other half with the application of the UCM. The time
measurements to solve the tasks are evaluated using two statistical methods: The
Euclidean distance and the Kullback-Leibler divergence of the measured data
distributions and the corresponding Gaussian distributions are computed.
The experiments demonstrate that the task execution durations were reduced by a
factor of up to six due to the application of the UCM (compared to the situation without
UCM). And the (qualitative) satisfaction factor of the probands increased by a factor of up
to four for all tasks due to the seamless and multimodal UCM. These results show that the
UCM supports communication for the elderly society in a seamless and intuitive way.IngenierÃa, Industria y Construcció
