Technical Writing Geek writes: "Another example of potential prior art for Yahoo's patent application would be the drag-and-pop interaction mechanism that was described in a 2003 report by by interaction design researchers. The report describes a user interface paradigm that involves displaying drop points near the selected object when the user begins to drag. The researchers created several implementations of the functionality described in the report, including one in Flash that can be tested on the Internet.
Since none of the other participants had submitted the drag-and-pop study as prior art, I decided to do so myself. I registered a user account at the peer-to-patent web site and filed the submission using the provided web form.
