Stereoscopic Project

This project was created over the course of three years and continues to be updated each year. The goal of the project is to enhance student learning by providing students enrolled in SHS 300: Anatomy and Physiology of the Speech Mechanism at the University of Illinois at Urbana-Champaign a three-dimensional viewing experience while studying the details of human anatomy. The focus of these images is on the anatomy of the respiratory, laryngeal, and articulatory speech mechanisms. In this course we use stereoscopy to image cadaver specimens. The images demonstrate the sequencing of dissection in the laboratory and can be viewed by students at their leisure, on their own computer screen, and outside of the anatomy laboratory. The 3D images provide the spatial depth impression that is critically important in understanding the spatial anatomy of structures under investigation.


Stereoscopic Imaging

Stereoscopic (3D) imaging is the science and technology dealing with two-dimensional drawings or photographs that are converted to three-dimensional images. The 2D images are viewed with both eyes in such a way that the image appears as a 3D image in space. Stereoscopic viewing requires binocular vision and a viewing device. Pictures are presented in pairs, side-by-side, at slightly different angles and observed through the viewing device.


Instructions for Viewing the Collection

Images must be viewed through a stereo viewer. Some viewers are very inexpensive but quite functional and there are many distributors from which to choose. The list below contains a few of these resources. Hold the viewer to your eyes and maintain your gaze at the center of the images.
