Flip experiment horizontally for presentation in MR

July 08, 2022 16:26

Hi,

our projector set up in the MR environment requires flipping the presentation of our experiment horizontally (due to the usage of a mirror attached to the head coil).

Is there a feature to easily achieve this in E-Prime 3?

Thank you,

Manuel

This topic was discussed long ago in the E-Prime Google Group, groups.google.com/group/e-prime. Try searching there.

Hi David,

I went through the google group and couldn't find a solution. I found that a few people had this problem and created screenshots that they flipped. This is not a working for my setup, unfortunately.

I was hoping to get a working solution from PST here.

Sorry you could not find the threads on the Google Group. Please look at these threads from 2008 & 2016 and see if they help at all:
https://groups.google.com/d/topic/e-prime/jEKaNwglKs8
https://groups.google.com/d/topic/e-prime/M-Au9LqPm40

BTW, you will not get any solution from PST here. This is a user forum, not PST Support. Sadly, users too often confuse this user forum with PST Support. If you want help from PST Support, then you have to submit a request to PST Support, not here. Best regards.

Hi David,

thanks for the efforts in pulling up these links. Yes, that's what I found before

I know that this is a user forum but it's also the first place the PST website directs users with questions to. So I was hoping the forum would be moderated/visited by PST staff as well.
I'll put in a request then but it seems like this feature has not been added to ePrime yet.

Thanks again,

Manuel

Just for fun I did some Googling and came up with the following:
https://www.aliexpress.com/item/2251832683812502.html
They charge US$338 + $46 shipping for this device. The seller, AliExpress, is an arm of the Alibaba Group which is a Chinese version of Amazon.com (and larger than Amazon.com). I have bought from them myself.

I also tried "hdmi mirror box" on eBay and found several examples starting at US$10.

One more alternative is to first bounce your video off of a front surface mirror and then direct that to the mirror for your subject.

Good luck!
