Virtual Magnifying Glass is designed for visually-impaired and others who need to magnify a part of the screen. Unlike similar programs it does not open a separate window for the magnification but instead puts a movable magnifying glass on screen.
VR Juggler is a virtual platform for virtual reality application development created at the Virtual Reality Applications Center at Iowa State University. Applications developed in VR Juggler can transparently move between a wide range of VR systems.
