This paper describes the implementation and evaluation of the second iteration of SMILE (<b><i>S</i></b>cience and <b><i>M</i></b>ath in an <b><i>I</i></b>mmersive <b><i>L</i></b>earning <b><i>E</i></b>nvironment), an immersive learning game that employs a fantasy 3D virtual environment to engage deaf and hearing children in math and science-based(More)
In this paper we describe the development of a new immersive 3D learning environment to increase mathematical skills of deaf children. The application teaches mathematical concepts and ASL (American Sign Language) math terminology through user interaction with fantasy 3D virtual signers and environments. The program can be displayed in immersive devices and(More)

The general goal of our research is the creation of a natural and intuitive interface for navigation, interaction, and input/recognition of American Sign Language (ASL) math signs in immersive Virtual Environments (VE) for the Deaf. The specific objective of this work is the development of two new gesture recognition systems for SMILETM, an immersive(More)
In this paper, we describe the development of two novel approaches to teaching math and science concepts to deaf children using 3D animated interactive software. One approach, Mathsigner, is non-immersive and the other, SMILE, is a virtual reality immersive environment. The content is curriculum-based, and the animated signing characters are constructed(More)
A conventional pinhole camera captures only a small fraction of a 3-D scene due to occlusions. We introduce the graph camera, a non-pinhole with rays that circumvent occluders to create a single layer image that shows simultaneously several regions of interest in a 3-D scene. The graph camera image exhibits good continuity and little redundancy. The graph(More)
We present a new highly interactive program to teach American sign language (ASL) for K-3 mathematics by 3D animation. We aim at increasing: (1) the opportunity for deaf children to learn arithmetic via interactive media; (2) the effectiveness of (hearing) parents in teaching arithmetic to their deaf children; (3) the effectiveness of ASL K-8 mathematics(More)
We describe a graphical user interface designed to allow non-expert users to pose 3D characters to create American Sign Language (ASL) computer animation. The interface is an important component of a software system that allows educators of the Deaf to add sign language translation, in the form of 3D character animations, to digital learning materials, thus(More)
