DISEÑO DE UN MODELO DE PERCEPCIÓN PARA AGENTES VIRTUALES INTELIGENTES BASADO EN EL SISTEMA DE PERCEPCIÓN DE LOS SERES HUMANOS

Resumen en español Una prioridad en Sistemas de Agentes Virtuales Inteligentes (AVIs) y Sistemas Multi-Agentes Virtuales Inteligentes (mAVIs), es introducir una percepción sensitiva similar a la que poseen los seres humanos que permita que los AVIs perciban, en tiempo real, el entorno que le rodea con una claridad de percepción similar a la que poseen los seres humanos. Algunos estudios dentro del área de investigación cognitiva introducen la percepción humana como el primer nivel de u (mas) n modelo de "awareness" (consciencia). Basándonos en estos estudios, se ha desarrollado un modelo de percepción basado en uno de los más conocidos modelos de "awareness" desarrollados para trabajo colaborativo (CSCW). Este modelo es conocido como "Modelo Espacial de Interacción" (MEI) y gobierna "awareness" en Entornos Virtuales Colaborativos (EVC). El modelo de percepción desarrollado extiende los conceptos fundamentales del MEI, introduciendo algunos factores propios de la percepción tanto visual como auditiva en humanos (como son la Agudeza Sensitiva o la Región de Transición Sensorial) y reinterpreta estos conceptos clave con el fin de introducirlos en el sistema perceptivo de un AVI. Una vez formalizado el modelo, se ha seleccionado una arquitectura de agentes para poder introducir, usar y validar este modelo. De entre todas las posibles arquitecturas, se ha seleccionado el Modelo de Triple Torre de Nilsson. La introducción de este modelo de percepción dentro de la arquitectura de agente seleccionada ha requerido la creación de un "motor de percepción" y un diseño semi-centralizado de percepción que permita manejar no sólo la percepción sensitiva del agente sino también algunos factores externos y adicionales tales como la atenuación Resumen en inglés A priority in Intelligent Virtual Agents Systems (IVAS) and multi- Intelligent Virtual Agents Systems (mIVAS) is to introduce human-like sensitive perception which allows an IVA to perceive its environment and surrounding objects in real-time with a human-like clarity of perception, gaining knowledge about its surroundings and experiencing any virtual simulated environment. Within the cognitive research area, there are some studies underwriting that human perception can b (mas) e understood as a first level of an "awareness model". Following on from this research, we have developed a human-like perceptual model based on one of the most successful awareness models in Computer Supported Cooperative Work (CSCW), called the Spatial Model of Interaction (SMI), which manages awareness in Collaborative Virtual Environments (CVEs) through a set of key concepts.The perceptual model developed, extends the key concepts of the SMI by introducing some human-like factors typical of visual and hearing human perception - like Sense Acuity or Sense Transition Region - which are reinterpreted with the aim of introducing them as the key concepts of an IVA human-like perceptual model. Having formalised the perceptual model, an appropriate agent architecture on which to use and test this perceptual model has been selected: a vertical layered architecture known as the Nilsson's Triple Tower Model. The introduction of this perceptual model into the agent perceptual block, has required the creation of a perceptual engine and the design of a semi-centralized approach to manage not just the sensitive agent perception, but also some other external and additional factors, such as attenuation. brain tissue must have a few cells bearing protein molecules that happen to resonate at its rotation frequency
