Strike One: Asirra
And so it begins. I mentioned some issues with reCAPTCHA, and received a this comment:
Have you tried Asirra?
So I tried it. Here are the results of my usability study:
- The images are really tiny until you hover over them.
- I found it awkward because I really can’t quickly identify the correct images without hovering over each one. It requires too much mouse precision, which slows me down.
- After selecting a few cats, I made the mistake of clicking the “Adopt Me” link, which took me to a different web site.
- When I finally clicked “Score Test”, it told me I’m a bot. (I’m not, unless of course I’m a replicant and simply don’t realize it. Hey…what’s that origami Unicorn doing on my desk?)
I suspect it thinks I’m a bot because I clicked that “Adopt Me” link, making it forget the previous selections.
In summary, this is another CAPTCHA that tries accomplishing a “mission” — adopting pets — which detracts from its usability as a CAPTCHA. In particular, the “Adopt Me” links get in the way.
