• Windows stand-alone application FrACT3.10.5.zip.
  On recent Windows versions you will see a dialog “… unknown publisher…”:
  This message is normal, allow it, explanation.
  With the latest Windows, you need to: right click, open, and allow.
• MacOS stand-alone application FrACT3.10.5.app.zip.
  Since MacOS 10.9: Must right click, open and confirm, explanation.
  If you just double click, MacOS suggests to trash, don’t :).

Very occcasionally there have been download problems. If so, don’t hesitate to contact me, we’ve always found a work-around. If the downloaded version does not work, it might be a security setting, easy to circumvent if you persist.

All options and default settings are described in this file: Manual [PDF]. I am happy to help in any way, but please be so kind to read the checklist and to peruse the manual before sending me questions.
[The manual is occasionally out of step with the very latest FrACT release…]

Most earlier versions still available below

“Face files” as used in McCulloch DL, Loffler G, Bruce N, Dutton G, Bach M (2011) The effects of visual degradation on face discrimination. Ophthalmic Physiol Opt 31:240–248.

Usage: Download “FaceFiles2011.zip”, decompress, store folder at any convenient location. Tick “allow experimental Face acuity” in Settings. Press “Faces” on the main screen. Navigate to the faces folder, select ALL and load all of them at once. Then the Faces test proceeds; the task is to select the odd-one-out from the four faces, actually quite difficult.

Sufficient distance from the screen is necessary to avoid distortion, just as for normal acuity assessment. Thus if you are testing subjects with normal vision, ≥2 m (for typical screen resolutions) is fine. If you are testing subjects with low vision, reduce the screen distance proportionally to avoid limitations by total screen size.

Needs FrACT version 3.7+.

This could be a “trojan”, like any program, yes, but it is not to the very best of my knowledge.

For the downloaded stand-alone version of FrACT, you do not need to have any Flash plugin or player installed. It is self-contained.

As to viruses: Macintosh users need not be very concerned, there are still (nearly) none for that platform. For Windows, I can state that I personally compiled this progam (using Flash CS4 on a Mac) with no malicious code and placed it on this site myself.

To store the settings, FrACT uses Flash’s “Local Shared Objects”, putting a file containing settings and temporary run results on your computer. Visit the Adobe Flash online settings manager to restrict how Flash stores these files; you can completely disallow such files to be saved, but then your settings won’t stick.

If you were using FrACT, please cite it when publishing.
