This post is out of date: check this one out!
After i posted my little prototype image with hot spots, I decided to go back into it and make it a bit nicer and high tech.
I used an image of my brother and I at AUReMIX 08 in Melbourne and made us the hot spots. Just using simple bits of C# code to call the animations and change the visibility parameter from visible to collapsed, I think it turned out pretty cool.
I used the vector tool to create specific hot spots around the people so that the hovers are very precise.
And a simple little on/off button to show a little information about the test.
What do you think? Would love some feedback.
