Yes you can do that. What you need is:

* Some kind of ir receiver for example : UIR/Irman etc etc

* 4 remotes with ( 1 ) button, these buttons need to send different signals, obviously.

* A .gir file that does the signaling who was the first one to press a button.

So this is very feasable.

Quite right guys,... hmmm, well i guess the signals should be about half a second appart,.. and if 2 people press at the same time you would get neither,.. or one of them by cheer luck...

Not to be contrary; but, wouldn't the remotes interfere with each other? Wouldn't they operate at the same frequency? How would the single IRMan sort out one code over another if the codes arrive at or near the same time? I could see this working OK with a wired (USB, maybe?) solution but not an over-the-air (IR) solution.

Bare in mind that this will work enless two people press the button at the same time, or within the time it takes to send an ir code, in which case it will probably recieve neither. So it depends how acurate you want it.

I just found this product and wonder if it will work with what I am looking for. I want to have 4 IR devices in an audience (a game situation) that when clicked will register in my pc as to which one clicked the device first. Can this be achived with Girder? What types of devices our input componets would be needed? I'm not real savy on these things so go easy on me.

thanks

Thanks for your reply. I did order that receiver so I am going in the right direction it would appear. I will have to look at Girder and see what I can do with it. I will probably be back with some more questions on this after I get into it. Thanks

I guess it depends on what the same time means. nanoseconds, microseconds, seconds etc. I'm just looking for some way that the first response could be displayed on a pc (on an overhead projector) that would indicate who was first. It is not rocket science in that it has to be that close. If two or three signals come in before it has read them all, does it just discard all the info? Give false reading? Any way to make it so that it reads the first signal and discards the rest? Your help is most apprecated. Any other ideas on how to achieve this?
