Event segmentation task

[I][edited from support email][/I]
We are trying to design an online event segmentation task, and were wondering if you could help us. The basic idea is that participants watch a video and press a button (e.g. the spacebar) to indicate when they think a new event has begun in the video (there are several events in the video). From the looks of it, this can be accomplished using DirectRT by changing the MinMax parameter in the Style menu in order to collect continuous responses throughout the trial. Do you have any input on this?

In MediaLab, try using an essay item. You can capture and record each time they hit a particular key by using the k parameter. See:

To display the video, you simply enter it as a background video. See:

You can also adjust the location of the essay window so that you don't see it--e.g., using(t2000) will move it off the screen completely in most cases.

Let me know if you have any trouble with it!
