We investigated the automatic assessment of expressive children’s oral reading of grade level text passages using a standardized rubric. After a careful review of the reading literature and a close examination of the rubric, we designed a novel set of prosodic and lexical features to characterize fluent expressive reading. A number of complementary sources of information were used to design the...

We propose a vision-based registration method for Augmented Reality (AR) that uses real scenes containing multiple planar structures. Our method provides users with an enhanced view of a real scene by overlaying computer-generated virtual objects onto images captured with a movable camera. The virtual objects are associated with a 3D planar structure and appeared to move with that structure. To...

This paper describes a model for evaluating a computer-generated plot. The main motivation of this project is to provide MEXICA, our plot generator, with the capacity of evaluating its own outputs as well as assessing narratives generated by other agents that can be employed to enrich its knowledge base. We present a description of our computer model as well as an explanation of our first proto...

The area of computer-generated animation as a tool for engineering analysis and design has been under development for a considerable number of years.,. In this paper, an attempt is made to describe some of the salient features of the development of computer animation techniques. This is accomplished by examining some of the history of the development, by exploring the types of animation techniq...

-Human discourse appears coherent when it refleets coherent human thought. However, computers do not necessarily store or process information in the same way that people do a.ud~ therefore, cannot rely on the structure of their reuouing for the structure of thehr dialogue,s. Instead, computer-generated conversation must rely on some other mechanism for its orgsaiisation. In this paper, we discu...

This paper describes a computer model for evaluating the interestingness of a computer-generated plot. In this work we describe a set of features that represent some of the core characteristics of interestingness. Then, we describe in detail our computer model and explain how we implemented our first prototype. We assess four computer-generated narratives using our system and present the result...

We report what we believe is the first realization of odd dark beams of finite length under controllable initial conditions. We obtain mixed edge–screw phase dislocations by reproducing binary computer-generated holograms. Two effective ways to control the steering of the beams are analyzed experimentally and compared with numerical simulations. © 2000 Optical Society of America [S0740-3224(00)...

A new kind of computer-generated hologram termed digital correlation hologram (DCH) has been developed and demonstrated with promising results. This hologram is composed of two separate sub-holograms. The reconstructed image is obtained as a result of a spatial correlation between the hologram's two parts. The DCH codes two complex functions which are generated by an iterative optimization proc...

We will present an interactive computer-generated hologram technique using spherical angular spectrum. The spherical angular spectrum consists of the frequency spectrum of the object wave in all-around directions. The spherical angular spectrum is computed by a formula of the Fourier coefficients of point light source. Given a spherical angular spectrum, one can generate a planar hologram at a ...

A system of two separated computer-generated holograms termed digital correlation hologram (DCH) is proposed and demonstrated. In each hologram a different computer-generated complex function is coded. The reconstructed image is obtained as a result of a spatial correlation between the hologram s two parts. The correlation between the two sub-holograms is implemented on a modified joint transfo...
