R²Z - Reiz-Reaktion-Zeit. A program
to measure times required to motor-react (pressing a key or the display) to different visual stimuli.
A simple data evaluation is also included. The program supports English (default) or
German (when detected as system language).|
Available for several operating systems, plus a "touch edition" for Android.
This software is primarily (but of course not only) intended for educational purpose and suitable for school and lower university classes.
But it's also just some fun to test your reaction times, kind of a very simple game.
Don't hesitate to contact me for further information!

This software is written in the language Hollywood and hence available for many systems, either
as native application or as .hwa-applet code. There is no additional
software required and it should run on any computer running one of the supported operating
systems. Be sure, you have downloaded the program version for your particular operating
system. You may need a processor better not less than 400 MHz and a few MB of available
RAM as well as a screen resolution of at least 800*600 pixels and minimum 16 bit colour
depth. For the non-Android versions you also need a keyboard. The touch version (=Android
version) requires a touch screen of course
Once you've downloaded the archive, unpack it and copy it to any destination you like (target drive needs at least 2.3 MB free space). You may put it on your harddsik, on a usb key or even on a server. There is no special installation process required.
Nach beendetem Download, das Archiv entpacken und einfach in ein beliebiges Verzeichnis kopieren (das Ziellaufwerk benötigt wenigstens 2,3MB freien Speicherplatz). Das Programm kann auf eine Festplatte, einen usb-Stick oder auch auf einen Server kopiert werden. Es gibt keinen gesonderten Installationsprozess.
Just doubleclick the program icon. Once the splash screen has vanished the program starts
with one window on a separate screen. The program window has a few buttons to chose from. At
the bottom of the window results of the last test done are shown. Initially this area is blank
of course, as there is no data to show yet.
Each test consists of 11 repetitions, the first trial doesn't get counted. It's a free shot to get into the actual test run. To avoid other attraction the program starts on its own screen and during a test all other items (including mouse pointer) get cleared.
Times of more than 1s are rated as invalid and will not get further evaluated. The 1s time is a reasonable value for all tests except maybe test #4 (cluttered background) and #8 (moving single object of a group).
In short: Hit the key as quick as possible but not before the stimulus is actually ready.
Internally all actual values are stored and can get exported to a html file by clicking the button "All results". The html file will get stored at a directory called "Resutls" which gets created within the directory the R²Z binary resides in. Each stored result file name contains the current date and a counter. Once the file has been created a browser window will open and show the results. The exact name and path of theresult file is obtainable from the browser's address field.
In case of test 5 & 6 not only the times getshown, but also whether the point had colour 1 or 2 and whether the user decided for colour 1 or 2. If the user pressed the key too early the value is set to 10 (stimulus) or 99 (user).
If you want to further process the data with a spreadsheet program (or what ever) just copy and paste the results from the html tables.
Grab a copy for your particular system from here:
V1.0 - Download (Hollywood player applet)
The archives (except the .hwa and .apk file) are packed with lha or zip (Windows).
Versions for Linux (x86, ARM or ppc), OS X (ppc), AROS (ppc) and OS4 (ppc) are yet available on request only. Please mail for a copy.
Windows says this program is potentially dangerous Well, it's not dangerous, but the binary is not signed and hence, the Windows smart screen warns about that issue. I don't want to judge whether that behaviour of Windows is good or bad in general but signing the program costs actual money. If you don't want Windows to annoy you with warnings you may self sign the program or ask me for a copy on a CD or usb stick (for a small fee).
I found a bug, want to discuss the data or methods, have a feature request or want to donate you a bag of gold ducates? Well, in that case don't hesitate to contact me.
