Current development focuses on utilizing the Phantom haptic interface in conjunction with sonification methodologies to develop a multiresolution multimodal visualization interface. Tactile Image Processing - intended to provide visually impaired individuals access to image based information through tactile rendering of images. Such rendering transforms color and gray scale images into a binary format that can be displayed on a tactile device, such as microcapsule paper, and manually explored. Current work focuses on the development of multiresolution edge extraction algorithms and texture analysis. Virtual Instruments - intended to provide improved access to computer controlled laboratory instruments.
Current work focuses on developing speech and audio interfaces for LabVIEW controlled instruments.
Additionally, remote access methods are being developed to allow Web based control of laboratory experiments and the creation of a virtual laboratory. Classroom Speechreading Aid - intended to provide hearing impaired individuals continuous visual access to an educator's lips in an everyday classroom setting where lighting, positioning, background noise, and other conditions may hinder perception. In this system, live video of the educator's lips is provided through a heads up display or a small desktop monitor. Research includes speechreading and multimodal studies, pilot testing, and further development of the system. Sign Language Video Communications - intended to provide the deaf and hard of hearing individuals the ability to communicate through guestures and sign language over telephone line and Internet connections.
