The purpose of this article is to discuss medication nonadherence and the use of relational agent technology as an aid in treating patients with schizophrenia. A team of mental health faculty—specialists in adherence, computer science, and statistics—collaborated to design the agent technology. This computerized virtual health counselor named “Laura” provides seven education modules about schizophrenia. Using preliminary data, two individual examples demonstrate the use of this technology. Implications for behavioral health nurses using this relational... Read more

Human beings not only have the ability of logical reasoning, but also can produce, control and express emotions. Making computers have the ability of generating emotions is a challenging task of affective computing. In this paper, we construct an emotion generation model using cognitive maps and show the generated emotions with 3D facial expression animation. This paper first introduces some basic theories about emotion, reviews some typical emotion models and compares their strengths and weaknesses.... Read more

La aceleración en el crecimiento de la capacidad del procesamiento de las computadoras y las técnicas de procesamiento del lenguaje natural, reabren interrogantes a cerca de la factibilidad de que las máquinas piensen; cuya implicancia impacta no sólo en el uso de Inteligencia Artificial en las organizaciones y la vida diaria, sino en la propia concepción de la naturaleza humana. En el presente trabajo se revén las ideas de Alan Turing, y de algunos de quienes... Read more

Virtual Agents are a set of computer programs capable of interacting with human beings in their own language (Spanish in our case). In particular, a Virtual Classroom Assistant is a Virtual Agent specialized in some field of knowledge featuring specific routines to provide tutoring, examinations, etc. Virtual Classroom Assistants (“AVC” in Spanish) can be accessed obliquely through a web browser, constituting a new and attractive pedagogical resource. This work, mostly based on the pilot tests carried out during 2009-2011, in the... Read more

Los Agentes Virtuales son un conjunto de programas informáticos capaces de interactuar con los seres humanos en su propio lenguaje (Español, Mandarín, Ruso, etc.), utilizando técnicas de PLN, Procesamiento del Lenguaje Natural, rama de la Inteligencia Artificial. En particular, un Asistente Virtual de Clase (AVC) es un Agente Virtual especializado en uno o más campos del conocimiento, con rutinas específicas para realizar tutorías, administrar exámenes, etc. Con una interfaz similar a un chat, los Agentes Virtuales...

There are significant advances in virtual world technologies that permit collaboration in a distributed, virtual environment. In the real world environment, distributed teams collaborate via face-to-face communication, using social interactions, such as eye contact and gestures, which provide critical feedback to the human decision maker. The virtual world affords the system designer the ability to evaluate an operator’s ability to respond to information (e.g., events, goals, objectives, etc.) in a complex, distributed team environment. The... Read more

This paper presents an overview and classification of security approaches based on computer analysis of human behavior. Overview of different methodologies is followed by an analysis of achieved accuracy rates, required equipment and prospects for future improvements. In particular the following broad categories of behavior-based authentication mechanisms are examined: Behavioral Biometrics (Authorship based, Human–Computer Interaction based, Motor Skill, and Purely Behavioral), Behavioral Passwords (syntactic, semantic, one-time methods and visual memory based), Biosignals (cognitive and semi-controllable...

Domestic and industrial robots, intelligent software agents, and virtual world avatars are quickly becoming a part of our society. Just like it is necessary to be able to accurately authenticate identity of human beings, it is becoming essential to be able to determine identities of the non-biological entities. This paper presents current state of the art in virtual reality security, focusing specifically on emerging methodologies for avatar authentication. It also makes a strong link between... Read more

The work discussed in this chapter involves a proposal to add human like attributes (emotions in this instance) to characters in games and virtual worlds to enhance user experience. The chapter begins by defining these computer controlled characters in the context of both games and virtual worlds, followed by a discussion on the human like aspects currently being integrated into these characters by developers. The chapter continues by focusing specifically on a particular case study... Read more

The possibility of creating thinking machines raises a host of ethical issues. These questions relate both to ensuring that such machines do not harm humans and other morally relevant beings, and to the moral status of the machines themselves. The first section discusses issues that may arise in the near future of AI. The second section outlines challenges for ensuring that AI operates safely as it approaches humans in its intelligence. The third section outlines... Read more
