The two researchers from Finland ask you to think about your most satisfying and unsatisfying experiences using AR application, and for your view on the usefulness of such applications and take the following survey. I must say that imho, mobile AR has not yet created a really satisfying moment, and the enjoyable moments it did create, didn't last for long (though, some of the creative things people do with mobile AR are really mind boggling).
Best of all, by participating in this survey, you enter a raffle to win one of 10 Amazon-vouchers, 50 euros of worth each. Considering that AR is still a niche, you have pretty good chances to win it. Even better, Salo has promised to share the results, so we'll can all learn from this survey.
