AR visualization tools on websites come in two forms. One shows a generic wall with the print in question on it. It could be above a sofa, above a bed, above a conference table, above a desk, etc. You pick the image you're interested in and the size, and it shows you what that furnished space would look like with that image on that wall.
The other allows you to upload an image of your own space and it will digitally superimpose the art you have selected in the size you have selected onto the wall.
The latter is, of course, more useful for visualization, but has privacy implications that I'm not comfortable with, so I would not put one of these on my website.
I did this poll because it's one of the "maybe" things on my list of tasks to get my online print sales set up. It's definitely not a priority. AR tools do seem all the rage, but I wonder how much use they get and whether they increase sales or not.
