Javascript issue?

For researchers.

Is there a way to preload images and then start the timer when they are loaded and ready to go?

See https://github.com/mattbk/changeblindnesstest/blob/master/views/results.html.twig#L29.

Both in code and in table/text.

Right now it's in change.js.

Close one issues, open several others...

While debugging, I'm getting repeated entries in the database every time I hit index.php?=finish. I think this is because $_SESSION is storing a lot of the data, so if they array is not overwritten, the same data are posted again.

Since it is likely that this application will be used by several participants in succession at the same computer, it is important that $_SESSION be emptied when each participant starts, in case a malfunction occurs and the test is ended prematurely.

Not sure if I can (or should) include Twig files here; probably better to include instructions for download and installation.

• Download Twig
• Copy the Twig folder (it was second-level for me) into install directory.

Hmm...

Some require rewrite, which I don't think is necessary. Some are hardcoded to go to places I don't have access.

Missing from the project from which this was forked. Needs to create a table and some fields to hold results.

• How are individual test-takers identified?
  • by IP

This is because I'm not sure how $_SERVER['REMOTE_ADDR'] works.

In case you have different file types than hardcoded .png or .jpg.

See https://gitlab.com/mattbk/bib-enterer and https://gitlab.com/eerc/pnlz.

I haven't gotten through the whole process yet, but looking at the db schema (as I can understand it), the (x,y) of each click is stored, but the accuracy (comparison with target zones in settings.json) is not.

These data should be stored in the database because it will save a step for the researcher.

Keep the results for each participant in order and together.

Set it in settings.json? Right now I think it is server time or GMT.

If you happen to click the screen between the two images being shown, I don't think the clicks are being recorded. I wonder if this can be fixed or not. It's fairly important, as having participants click multiple times will make their response times longer.

It would be easier for people to input target zones in a CSV file in Excel than in a JSON file.

Create a set of scenes that show you where to click and have an associated settings.json file. These can be used to make sure application is working properly and teach people how to use it.
