Here's one of its windows:Īn overview video describing the system is available here. Id always thought the screen saver map was procedurally generated. I also created a full-featured data processing and analysis program in MATLAB to handle the summary and time-series data generated by the C++ program when running experiments on the VSA. Microsoft Windows was known to come with a variety of screensavers, especially from the Windows 9x period (95-98-ME), but this particular one known as the 3D. r/Minecraft - The full map of the Windows 95 3D Maze is here. The program for this apparatus was fairly involved, as it required a GUI (which I implemented using the cross-platform wxWidgets GUI library), affine transformations to map 3D coordinates from the limb tracker to 2D coordinates in space and vice versa (after deriving these transformations, I tested them in MATLAB and then incorporated them into the program itself using LAPACK and Armadillo), and integration with third-party APIs for the various tracking hardware. It includes a monitor, a partially-silvered mirror (to modulate or eliminate limb visibility), a limb tracking system, an optional head-mounted eye tracker, and a custom multi-threaded C++ program to run experiments, provide the experimenter with real-time feedback on a participant's performance, and collect tracking and performance data. I designed this apparatus for behavioural experiments involving reaching and eye movements (the basic concept is adapted from a 1995 paper by Daniel Wolpert et al.).
