Hi Ben, On 14/07/07, Ben Maurer <bmaurer@andrew.cmu.edu> wrote: <quote> Doesn't the refresh button make sense *after* the challenge. </quote> It makes sense to put the refresh button after the challenge, but not after the edit box that prompts the user to answer the challenge. At the moment, you pose the challenge, request that the user answers the challenge, and then after they have responded to the challenge, inform the user that they could change the challenge if they found it difficult (plus other options) - unfortunately, users with visual and mobility impairments are very unlikely to discover those options, as they're not easily available to them.

What I'd really like is to have an out-of-band set of buttons that the user can easily move in to. </quote> Requiring keyboard users to cycle through three tabs is a small price to pay, in comparison to people who cannot readily change aspects about themselves, to compensate for people who will completely miss those options if they are not available with the keyboard alone. Putting tabbing through three elements above the needs of people with disabilities will always be at odds with accessibility.

Sadly, if a services is not keyboard accessible, the service cannot be considered to be accessible at all. The ultimate solution would be to block access to bots without blocking users with disabilities; testing humans by their ability to perform a task will always be at odds with this quest (sensory, mobility, and cognitive difficulties); in the meantime, we at least need to ensure that basic input/output devices are capable of allowing anyone to perform a task that a bot is (7 out of 8 times) unable to perform.
