| As part of “Project LITE: Light Inquiry Through Experiments” we have developed software that assists individuals in investigating for themselves a variety of binocular vision phenomena. The software is written using HTML5 and is designed for smart phones and MP3 players, such as the iPhone and iPod running the Apple iOS, and similar devices running the Android operating system. We have also developed an inexpensive binocular viewer for use with these phones. The goal is to help the user explore: binocular rivalry; binocular lustre; depth perception arising from binocular disparity; dichoptic color mixing; persistence of vision; and other features of binocular vision. Included in our new software applications suite is a controllable random dot stereogram (RDS) application that permits user selection of various images, textures, and image separations; a stereoscopic vision app; a Pulfrich effect demonstration; a thaumatrope; and an app for exploring auto random dot stereograms (ARDS). Preliminary studies of binocular color mixing using our viewer and apps suggests that “dichoptic” or “cortical” yellow perception occurs in more than half of the trial subjects tested. All of our software can be found at http://lite.bu.edu. Project LITE is supported in part by NSF Grant # DUE - 0715975. |
