“…Finally, there is a positive correlation between security concerns and ECA-friendly (an element of ECA social ). It would be interesting to confirm this very tentative observation with more data, as it would add to an effect found in previous research that an ECA on the interface of a biometric system heightens security and privacy concerns by its mere presence (Hernández Trapote, 2011). Now we see that the effect might be intensified by some sort of psychological association of social openness with diminished security.…”

“…When studying biometric technologies, it seems reasonable to assume that security and usability are closely connected (Hernández Trapote, 2011). Angela Sasse, a leading expert in human factors applied to security interfaces, has proposed a taxonomy (of sorts) of usability aspects, 41 its main components being performance (which covers effectiveness and efficiency), user satisfaction, and costs (Sasse, 2005).…”

“…These two parts of the experimental system were described in detail, respectively, in two previous doctoral theses: the biometric phase in (Hernández Trapote, 2011) and the domotic phase in (López Mencía, 2011). Relevant parts of the raw dataset that will be the focus of the analyses and discussion in this appendix were examined previously in these works.…”

This Thesis presents two related lines of research work contributing to the general fields of Human-Technology (or Machine) Interaction (HTI, or HMI), computational linguistics, and user experience evaluation. These two lines are the design and user-focused evaluation of advanced Human-Machine (or Technology) Interaction systems.The first part of the Thesis (Chapters 2 to 4) is centred on advanced HMI system design. Chapter 2 provides a background overview of the state of research in multimodal conversational systems. This sets the stage for the research work presented in the rest of the Thesis.Chapers 3 and 4 focus on two major aspects of HMI design in detail: a generalised dialogue manager for context-aware multimodal HMI, and embodied conversational agents (ECAs, or animated agents) to improve dialogue robustness, respectively. Chapter 3, on dialogue management, deals with how to handle information heterogeneity, both from the communication modalities or from external sensors. A highly abstracted architectural contribution based on State Chart XML is proposed.Chapter 4 presents a contribution for the internal representation of communication intentions and their translation into gestural sequences for an ECA, especially designed to improve robustness in critical dialogue situations such as when miscommunication occurs. We propose an extension of the functionality of Functional Mark-up Language, as envisaged in much of the work in the SAIBA framework. Our extension allows the representation of communication acts that carry intentions that are not for the interlocutor to know of, but which are made to influence him or her as well as the flow of the dialogue itself. This is achieved through a design element we have called the Communication Intention Base. Such r pr s ntation of "non-clar " int ntions allows th construction of communication acts that carry several communication intentions simultaneously. Also in Chapter 4, an experimental system is described which allows (simulated) remote control to a home automation assistant, with biometric (speaker) authentication to grant access, featuring embodied conversation agents for each of the tasks. The discussion includes a description of the behavioural sequences for the ECAs, which were designed for specific dialogue situations with particular attention given to the objective of improving dialogue robustness.Chapters 5 to 7 form the evaluation part of the Thesis. Chapter 5 reviews evaluation approaches in the literature for information technologies, as well as in particular for speechbased interaction systems, that are useful precedents to the contributions of the present Thesis. The main evaluation precedents on which the work in this Thesis has built are the Technology This Thesis is the result of an unlikely string of developments that set me along the path of doctoral studies and kept me on course throughout them. I have always entertained a vague dream of being a researcher, but I probably would never have come as close as I now am, at this time at which I sear...
