  1. 1. How can I help you? : The delivery of e-government services by means of a digital assistant

    Författare :Matthew M. Raoufi; Olov Forsgren; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Informatics; computer and systems science; Digital assistant; E-government; E-services; Embodied Conversational Agent; Accessibility; Informatik; data- och systemvetenskap; Informatics; computer and systems science; Informatik; data- och systemvetenskap; computer and systems sciences; data- och systemvetenskap; e-governmetn; e-services; embodied conversational agent; accessability.;

    Sammanfattning : This thesis focuses on the delivery of government services to citizens with a particula r emphasis on enabling those who are at risk of exclusion from the digital society to gain access to it. Following in this direction, one of the frequently addressed issues concerning the accessibility of e-services and information in government websites is found to be the users’ unawareness concerning the location of the desired information or service.

  2. 2. Developing and evaluating co-speech gesture-synthesis models for embodied conversational agents

    Författare :Taras Kucherenko; Hedvig Kjellström; Gustav Eje Henter; Iolanda Leite; Jonas Beskow; Stefan Kopp; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Human-agent interaction; gesture generation; social robotics; conversational agents; non-verbal behavior; deep learning; machine learning; Computer Science; Datalogi;

    Sammanfattning :  A  large part of our communication is non-verbal:   humans use non-verbal behaviors to express various aspects of our state or intent.  Embodied artificial agents, such as virtual avatars or robots, should also use non-verbal behavior for efficient and pleasant interaction.

  3. 3. Scalable Methods for Developing Interlocutor-aware Embodied Conversational Agents : Data Collection, Behavior Modeling, and Evaluation Methods

    Författare :Patrik Jonell; Jonas Beskow; Joakim Gustafsson; Gustav Eje Henter; Justine Cassell; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-verbal behavior generation; interlocutor-aware; data collection; behavior modeling; evaluation methods; Tal- och musikkommunikation; Speech and Music Communication;

    Sammanfattning : This work presents several methods, tools, and experiments that contribute to the development of interlocutor-aware Embodied Conversational Agents (ECAs). Interlocutor-aware ECAs take the interlocutor's behavior into consideration when generating their own non-verbal behaviors. LÄS MER

  4. 4. Developing Multimodal Spoken Dialogue Systems : Empirical Studies of Spoken Human–Computer Interaction

    Författare :Joakim Gustafson; KTH; []
    Nyckelord :Spoken dialogue system; multimodal; speech; GUI; animated agents; embodied conversational characters; talking heads; empirical user studies; speech corpora; system evaluation; system development; Wizard of Oz simulations; system architecture; linguis; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis presents work done during the last ten years on developing five multimodal spoken dialogue systems, and the empirical user studies that have been conducted with them. The dialogue systems have been multimodal, giving information both verbally with animated talking characters and graphically on maps and in text tables. LÄS MER
