This article presents a new approach to designing brain–computer interfaces (BCIs) that explicitly accounts for both the uncertainty of neural signals and the important role of sensory feedback. This approach views a BCI as the means by which users communicate intent to an external device and models intent as a string in an ordered symbolic language. This(More)
— This paper presents an interface that allows a human pilot to remotely teleoperate an unmanned aircraft flying at a fixed altitude with input only from an electroen-cephalograph (EEG), which is used in this case to distinguish between left-and right-hand motor imagery in the brain. The approach is to construct an ordered symbolic language for smooth(More)
We propose a complementary approach to the design of neural prosthetic interfaces that goes beyond the standard approach of estimating desired control signals from neural activity. We exploit the fact that the for a user's intended application, the dynamics of the prosthetic in fact impact subsequent desired control inputs. We illustrate that changing the(More)
In this technical report, we investigate the use of passive RFID technology for object localization and tracking. This work is motivated by the desire to design, and build, robust smart spaces (pervasive spaces), and in particular their application in the area of hazard aware spaces. In particular we are interested in building spaces that can detect hazards(More)
Inverse optimal control is the problem of computing a cost function with respect to which observed state input trajectories are optimal. We present a new method of inverse optimal control based on minimizing the extent to which observed trajectories violate first-order necessary conditions for opti-mality. We consider continuous-time deterministic optimal(More)
Localization of acoustic sources has been an area of research starting primarily with underwater acoustics. Recently, localization of sources in air has become a topic of interest for automatic detection, surveillance and tracking for military applications. Other application include novel teleconference devices, specifically automatic focusing on the person(More)
