The experiment will take approximately 5-10 minutes. You will be asked to assign labels (line, arc, polyline, polygon, ellipse, or other) to a number of strokes taken from hand-drawn sketches. Additional details will be provided on the next page.
As gratitude for your participation in this study you will be entered into a lottery to receive a $50 SuperGiftCertificate from http://www.giftcertificates.com which is redeemable at hundreds of both online and good old fashioned stores. You get one entry in the lottery for each session you complete. In addition, you may refer your friends to participate and the person referring the winner will also receive a SuperGiftCertificate worth $25. On the next page you must provide us with a valid e-mail address for both yourself and the person who referred you so that we can give you your prize.
We take your privacy seriously and as such we have registered this study with COUHES. They request that we inform you that:
Participation is voluntary
You may decline to answer any or all questions
You may decline further participation, at any time, without adverse consequences (although you will not be entered into the lottery until completion of the experiment).
Anonymity is assured (email addresses will be kept separate from the data and will only be used to contact winners or by your consent to participate in future surveys and studies, as described on the following page).
Data collected will be reported in such a way that your identity is protected
Proper measures will be taken to safeguard the data
We reserve the right to disqualify from the lottery anyone who we deem has not made a good faith effort to choose accurate labels.
