The increasing decentralization of computing resources and the proliferation of personal and small business computers create new problems in computer security. One such problem is the protection of externally supplied software, i.e., software supplied by other than the users/owners of these small computers. In the case of personal and small business computers, proprietary software serves as the primary example. In distributed systems comprised of autonomously managed nodes, members of the user...

This case study analyzes the factors that influence trust and acceptance among users (in this case, test pilots) of the Air Force's Automatic Ground Collision Avoidance System.

These factors are...

Accurate and efficient real-time cognitive workload assessment has many important applications, and physiological monitoring has proven quite helpful with this assessment. One such physiological signal, the electrooculogram (EOG), can provide blink rate and blink duration measures.

This algorithm does not require baseline data and is adaptive in the sense that it works for a wide...

We developed an optimization-based approach that can efficiently solve such problems.

Unlike their human counterparts, most autonomous systems to date are not effective at characterizing or bounding mission risk. In this project, we enabled the development of risk-sensitive autonomous systems through three main contributions: first, we introduced cRMPL, an extension of RMPL where one can specify acceptable risk levels for different mission segments through the addition of chance constraints. Second, we extended the continuous planner, used by our executive, to generate and adapt...

We present PPC (Plan Projection and Clustering), an algorithm that creates a plan hierarchy for case-based plan recognition systems. PPC is motivated by a desire to improve the response time of robots working in collaboration with humans. It projects the plans of a case base into a Euclidean space and iteratively clusters plans within that space, producing an abstraction hierarchy. Case retrieval traverses down this hierarchy and requires fewer comparisons than a search of the corresponding...

Accurately modeling uncontrolled agents (or recognizing their behavior and intentions) is critical to planning and acting in a multi-agent environment. However, behavior recognition systems are only as good as their observations. Here we argue that acting, even acting at random, can be a critical part of gathering those observations. Furthermore, we claim that acting intelligently via automated planning can significantly reduce the time it takes to confidently classify agent behaviors. We...

To perform complex tasks, a team of robots requires both reactive and deliberative planning. For reactive control, a restricted variant of Linear Temporal Logic called General Reactivity(1) can be used to synthesize correct-by-construction controllers in polynomial time, but they often ignore time and resource constraints to maintain tractable synthesis. For deliberation, hierarchical planning can be used to reason about time and resources. However, the coordination of reactive control and...

Models of errors during routine sequential action are typically interface-independent. We present here evidence that different task spatial layouts, however, result in different patterns of sequence errors. We explain this data by expanding upon the Memory for Goals framework's activation-based, sequential process to include environmental (such as visual) contextual cues, as well as a richer priming structure. We show a strong qualitative and quantitative fit to experimental data.

Advanced Driver Assistance Systems (ADAS) have made driving safer over the last decade. They prepare vehicles for unsafe road conditions and alert drivers if they perform a dangerous maneuver. However, many accidents are unavoidable because by the time drivers are alerted, it is already too late. Anticipating maneuvers a few seconds beforehand can alert drivers before they perform the maneuver and also give ADAS more time to avoid or prepare for the danger. Anticipation requires modeling the...
