Conveying Topographic Information with 3d Printed Models and Tactile Maps

Please join Raymond (RJ) Perry Thurs May 11 at 2:00 in Boardman 336 for his Masters project talk entitled: CONVEYING TOPOGRAPHIC INFORMATION WITH 3D PRINTED MODELS AND TACTILE MAPS Abstract Background: Blind and Visually Impaired (BVI) spatial learning research is mostly focused on indoor learning and cityscape learning. Little significant research has been conducted regarding […]

Using contextual knowledge for trust strategy selection

Abstract: In open multiagent systems in which some of the agents may be self-interested, it is vital that an agent be able to make trust decisions about its peers to determine which of them may be untrustworthy and how to behave in response. The agent’s context, including the environment, observed and inferred actions and motives […]

Representing and communicating context in multiagent systems

Abstract: Context-aware agents operating in a cooperative multi agent system (MAS) can benefit from establishing a shared view of their context, since this increases coherence and consistency in the system’s behavior. To this end, agents must share contextual knowledge with each other. In our prior work on context-mediated behavior, agents used frame-based contextual schemas (c-schemas) […]

Distributed, context-based organization and reorganization of multi-AUV systems

Abstract: Many tasks requiring multiple autonomous underwater vehicles (AUVs) are simple, with static goals, of short duration, and require few AUVs, often of the same type. Simple coordination mechanisms that assign roles to AUVs before the mission are sufficient for these multi-AUV systems. However, for tasks that are complex and dynamic, of long duration (implying […]

Toward distributed context-mediated behavior for multiagent systems

Abstract: Although much attention has been devoted to modeling and using context in intelligent agents, relatively little has been given to the problem for multiagent systems (MASs). Yet, just as with an individual agent, context affects how a MAS should behave. In this paper, we discuss an approach to distributed context management for multiagent systems. […]

Context and the virtual human

Abstract: Artificial agents that simulate aspects of human behavior are expected to behave much like a real human in a similar situation would. Human behavior however, is largely context-dependent. Ignoring the effect context can have on an agent’s behavior can hinder the quality and plausibility of agent’s behavior. In this paper, we present a context-driven […]

context-mediated behaviour

Abstract All effective agents are context-sensitive. This is true for biological agents, and it must also be true for artificial agents if they are to succeed. Context-mediated behavior (CMB) is one approach to endowing artificial agents with context-sensitive, context- appropriate behavior. It relies on explicitly representing contexts—important classes of situations—as contextual schemas and associating with […]
