This type of challenge allows the transcription of images.
Two images are displayed:
- an image for which we know the answer
- the other image for which we don't know the answer
The order of the images is random.
To validate the challenge the user must enter the correct transcription for the image for which the answer is known. The answer for the second image will be used to annotate it.
From this challenge you can access the audio captcha to allow visually impaired people to respond.
