: We present a new image-based process for measuring the bidirectional reflectance of homogeneous surfaces rapidly, completely, and accurately. For simple sample shapes (spheres a...

Abstract. We have developped a physically-based model where an object is represented by a set of mass points on its contour. Each object may be defined locally and physically usin...
This report details our development of a computer controlled spotlight with four actuated degrees-of-freedom for pan, tilt, linear movement, and beam focusing. We review the mecha...
This study investigates dynamic 3D target acquisition. The focus is on the relative effect of specific perceptual cues. A novel technique is introduced and we report on an experim...
This paper presents a measure for assessing the perceived hardness of a haptic surface based on associated physical variables. This metric, named extended rate-hardness (ERH), is e...
