Res. Meth, Inst. & Comp. published 30 years ago!), using CBuilder 1.0 (Borland/Embarcadero). So Jeda now has about 6 million lines of code distributed in about 50 cpp files and using about 40 windows. All stimuli described in my publications used Jeda, and are available for download together with many examples and visual illusions.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>Jeda runs on Windows (XP, Windows 7, Windows 10), using GUIs and menus, with no need to program or write code. Jeda allows interactively edit graphics (from simple shapes to 3D clouds), animations (2D and 3D, RDKs), manage event sequences, device contingent displays, palettes, etc.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>Jeda implements tools for running psychophysical experiments (Constant stimuli, staircase, adjustment, MEEG, fMRI, EyeTracking). <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US> Jeda comes with a User Guide and a documentation, including on-line contextual Help. <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>Jeda implements DirectX utilities with several available spatial resolutions, bit depths (8 or 32 bpp) and refresh rates, depending on your hardware capabilities.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>Jeda can be used in single screen mode although it should preferably be used in dual screen mode.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>Jeda is interfaced with several eye-trackers (EyeLink, TheEyeTribe, Livetrack, SMI, Pertech), devices (Joystick, EEG/MEG, fMRI, Webcam), manages images (BMP files), movies (AVI files), sounds (WAV files), 3D files (WRL files) and can be used to export images (BMP files) and movies (AVI files). Device contingent displays can easily be edited using dedicated tools. Serial port and TCP/IP capabilities are also available (e.g. for controlling an Arduino).<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>Tools for visualizing experimental data are provided, and Matlab scripts are available (on demand) for converting and visualizing Jeda Data files, as well as for further analyses.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Jeda is available as is. Thus bugs probably still exist, and can possibly be corrected if reported (by sending emails at jeanlorenc at gmail dot com). In case of interest, I may include additional developments and functions (on reasonable demand, and depending on my capabilities and availability). <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>I can, on request, share the C++ source code and the compiler (CBuilder Borland 32 bits), for those willing to reuse the code, and can make a sandbox available for those willing to add or test new functionalities (Send an email to jeanlorenc at gmail.co<a name="_GoBack"></a>m).<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p></div></body></html>
