Human Computer Interaction

In this work, we show that the estimation errors are frequency dependent and that by combining multiple frequency signals, the overall RMS estimation error can be significantly reduced.

We present freeform interactive speakers for creating spatial sound experiences from a variety of surfaces. Traditional surround sound systems are widely used and consist of multiple electromagnetic speakers that create point sound sources within a space.

We present freeform interactive loudspeakers for creating spatial sound experiences from a variety of surfaces.

In this paper, a transducer to monitor the curvature of a tagged object for backscatter RFID sensors operating at 5:8GHz is presented.

In this paper we report on a magnetoquasistatic orientation sensor that uses the magnetoquasistatic coupling between an electrically small emitting loop (magnetic dipole) and seven vertical receiving loops located on a circle of radius 12.19 m to determine the orientation of an object.

This paper presents such a backscatter sensor system operating in the 5.8 GHz unlicensed frequency band that wirelessly senses displacement between one and five millimeters.

An American football is tracked using a long-range magnetoquasistatic position and orientation measurement system.

In this work, we introduce a magnetoquasistatic tag developed for tracking an American football during game-play.

We present Lumitrack, a novel motion tracking technology that uses projected structured patterns and linear optical sensors.

We use a Ground Penetrating Radar (GPR) to localize eggs of sea turtles laid in sand. GPR technology has been developed to detect subsurface structures, and successfully applied in archeology, civil engineering, and demining.
