Need some help for an exhibition/ artwork

Artists!!!!!!!!!!!!!! You sure take the long route just to display a few pictures.

And what's up with the dirt. Don't you know that someone will be forever tracking the stuff about the exhibit?

Oh well, I guess you are determined to do this, and I have absolutely no appreciation of the arts, so go on with it.

The cat and squirrel and probably the gremlin, not GREMLIN, but sb will no doubt have opinions. Vader may even drop a hint or two. Wrong forum? Nope. There's plenty of wacko artists here who will dive right in. Hum, don't think we have any gophers as members.

Oh well.

Cheers The Omen, stick around.

What's a PABU? What's an IC?

What's the point?

Can't read fuzzy text that accompanies girl walking across pressure button floor.

EC? ph? Oh, Image Cells. ICs. Never heard it put much like that.

What is the idea?

Girls think of things and like heavy shoes?

We remember things when we walk towards other events?

Does not need really to make sense to me.

can send image direct to you if interested. cannot scale image any larger on thread for some reason.

Cheers,

The Omen

This looks interesting. The basic detail of the floor makes sense. You might want surround each push button with a wood or like spacer to keep the buttons from being pushed too far (also from repeatedly overcompressing the rubber surrounds).

I'm not very familiar with all the discrete-inputs-to-PC possibilities, but I think software like LabView or Think and Do would be well suited to this. Good luck! I wonder how long it will take viewers to realize that their position on the mat dictates where the images appear. Or get enough people to occupy the mat so that all images appear, completing a full picture.

Please keep us posted on the progress of this.

Hi Omen, you may want to consider using Pressure Mats rather than boards and switches. Speak to an alarm company about how much pre-load mats can have.

Alternatively use load cells, not switches, under boards.

I suggest these, as opposed to switches, as calibration is external to the 'box' and mats remove the need for anything but an external frame to contain the dirt.

Interesting idea. These are about 2.6 ft x 1.8 ft, whereas the original design is about 2.1 ft x 2.1 ft for each cell in the floor. They were priced at US$ 40 each x 36 = US$ 1440; plus a simple mat on top. This might be more economical than the wood frame + push buttons + rubber surrounds (and maybe spacers) + top mat.

this sounds so much more efficient! thanks a bundle. I guess i need to look into what the pressure mat load bearing is for activation and if that can be manipulated...any thoughts on that, please let me know.

yes they are a little larger than the desired size as mentioned, but slight overlays or gaps wouldn't be too disastrous.

I also got word from a friend about connecting them to a computer via an arduino http://www.arduino.cc/. Also MAX/ PSP was recommended for the visual programming of the image grid cells.

Any experiences with either?

Alas, my experience with these apps is zilch. I suspect that will be the least of the challenges, though.

One other thing I notice. The projector as illustrated is off axis to the wall. If it projects a rectangular image, it will come out as a trapezoid on the wall. However, if you compensate beforehand by making the pre-projection image trapezoidal in the other direction, it can come out rectangular on the wall.

no worries with the projection, was just an image to illustrate idea.

have no problems installing projectors, was part of my job for quite some time.

Hi Omen. I just assumed this work is in Sydney(?) The DSE link is not the 'only link', nor I suspect the best price - or only size. Overview of how they work, so far as interfacing is concerned;

I don't think you want overlays, but it's no more drama than having several people wandering about. Equally it is possible to have them cut to size - provided you get someone who knows what they are doing. E.g an alarm installer.
