Computer Vision for Wildlife Monitoring: Detecting Brown Howler Monkeys using YOLO
Gabriel Ferri Schneider, Guido Luis Glufke Mainardi, Paulo Ricardo Knob +4
Urban expansion threatens global biodiversity, especially affecting arboreal species due to the fragmentation of forest habitats. The movement of arboreal species across disjointed…
LLM-Driven Personalities for Decision Making in Emergency Simulations
Stefano Calzolari, Rubens Montanha, Gabriel Schneider +5
For virtual humans to appear believable, they must exhibit agency and spatial awareness while interacting with their environment in ways that reflect competence and intelligence. A…
True to Tone? Quantifying Skin Tone Fidelity and Bias in Photographic-to-Virtual Human Pipelines
Gabriel Ferri Schneider, Erick Menezes, Rafael Mecenas +3
Accurate reproduction of facial skin tone is essential for realism, identity preservation, and fairness in Virtual Human (VH) rendering. However, most accessible avatar creation pi…
Are You Listening to Me? Fine-Tuning Chatbots for Empathetic Dialogue
Paulo Ricardo Knob, Leonardo Scholler, Juliano Rigatti +1
Conversational agents have made significant progress since ELIZA, expanding their role across various domains, including healthcare, education, and customer service. As these agent…
Evaluating and Comparing Crowd Simulations: Perspectives from a Crowd Authoring Tool
Gabriel Fonseca Silva, Paulo Ricardo Knob, Rubens Halbig Montanha +1
Crowd simulation is a research area widely used in diverse fields, including gaming and security, assessing virtual agent movements through metrics like time to reach their goals,…
Study of Non-Verbal Behavior in Conversational Agents
Camila Vicari Maccari, Gustavo Galle de Melo, Paulo Ricardo Knob +1
This paper studies the non-verbal behavior of a conversational agent named Arthur. We propose the development of body movements for this agent, which interacts solely through voice…
Crafting Realistic Virtual Humans: Unveiling Perspectives on Human Perception, Crowds, and Embodied Conversational Agents
Rubens Montanha, Victor Araujo, Paulo Knob +4
Virtual Humans (VHs) were first developed more than 50 years ago and have undergone significant advancements since then. In the past, creating and animating VHs was a complex task.…
Moving Virtual Agents Forward in Space and Time
Gabriel F. Silva, Paulo Knob, Carlos G. Johansson +2
This article proposes an adaptation from the model of Bianco for fast-forwarding agents in crowd simulation, which enables us to accurately fast forward agents in time. Besides bei…
WebCrowds: An Authoring Tool for Crowd Simulation
Gabriel Silva, Paulo Knob, Rubens Montanha +1
Crowd simulation is an area of research largely used in the game industry. From the movement of a single NPC to the movement of an entire army, crowd simulation methods can be used…
