Keypress RT relative to video

[Anthony Barnhart]

Thanks for this great resource.  I'm still acquainting myself with the possibilities of ScriptingRT.  Is it viable to collect a reaction time relative to a timestamp wtihin an embedded video?

Best,

Tony,

to be honest, I am still acquainting myself with the possibilities.
Because scriptingrt is a flex library and thus simply an addition to the
vast possibilities of flex, there is so much to explore.

re video: I have no clue, and I have never tried it. I would suggest you
simply try it out. I imagine it should be possible to place a video in a
frame. I am not sure whether the reaction than cleanly ends the video,
and how often you can do it, but there is no other way but trying it.

If you get it to work, I am happy to evaluate it together with you. I
have some hardware here where we can measure how exact the latency
measurement is if video is running.

Do you want to give it a try?

cheers,
thomas

Hi Tony,

I think you can do this using the NetStream ActionScript library (see this example of an embedded video using NetStream). A call to NetStream.time would give you a millisecond-accurate timestamp of the current position in the embedded video. With a little bit of work you could get ScriptingRT to either log that timestamp directly, or work it into a normal Item sequence.

Thanks so much for the advice and resources, folks!  I will pow-wow with my collaborators now that I have some confidence that what we want to do is possible.

I really appreciate the help!

Best,

Tony
