Task

For each of the N images, answer yes or no to the above question. Only answer Yes to real photos. Always answer No to cartoon, drawing, or CG rendering. Here are some examples:

What's New?

• We will perform an additional check on the accuracy after the submission. Though very unlikely to happen, you HIT would still possibly be rejected if your accuracy is severely low in the additional check.
• You have 5 chances to click the [submit] button which triggers an accuracy check. Between each two clicks, you have to wait for 20 seconds to make sure you do a meaningful refinement.
• If you cannot pass the accuracy check within 5 chances, you may still refine your response and submit the hit once it passes the check. However, your result will be checked more throughly offline before approval, and it is more likely to get rejected. Therefore, do not abuse the submit button. Try to have good results before you try to submit.

Disclaimer

• If some images are not displayed properly, please let us know and do NOT continue working. Keep on working under this situation may cause your hit rejected.
• Although the task is not adult-oriented, some images are automatically crawled from the Internet, and in some rare situations, they may be disturbing due to nude, violent or scary photos.

Submit

• After you respond to all of the images, the [submit] button will be enabled.
• If your accuracy is too low, you will not be able to submit. You will have to improve your answers first.

Usage

• Maximize your window size
• Keep the right arrow [→] key (or [d] key) pressed down to move continuously from an image to the next. Release the key when you see an image for which the answer should be YES.
• Use [space] key to toggle the answer to YES. The default answer is NO.
• Use the left arrow [←] key (or [a] key) to go back to the previously seen images, if you skipped an image accidentally.
