I am designing an experiment to test people's trust in certain images and was hoping to get an idea of what parts of the image they trusted/did not trust. I was thinking of creating something similar to Facebook tagging where a participant might click on a part of an image and a text box would open so they could type a comment. I have looked at various ways of doing this but have had no luck so far.
I am currently thinking the answer may lie in recording a click event by co-ordinates on the picture, having that click open a dynamic text box below/beside the image that they can type into, and then I would just have to match the click events with the text they enter when all data is exported.
Any thoughts on whether I am on the right track? Any help or ideas would be verrrry much appreciated - been pulling my hair out over this one!
Think you're on the right track. Check out these tutorials to see if they help. Basically they show how to create Human Intelligence Tasks (HITs) that ask Workers to draw a box around objects, then either type in a label, select a pre-defined label from a drop-down, or apply no label at all.
Hope that helps!
