As a blind or visually handicapped user, I would like to be able to register at https://guru3.eventphone.de/register in order to use the services.

Describe the solution you'd like

There is no clear solution. We are looking for a solution that works well for blind users and is not from google.

Describe alternatives you've considered

  Type Hans, but not Sandra.
  Type yellow, not red.
  Don't type camel, type llama.
  What's three plus five?
