I was responsible for most of the programming beneath the navigation bar on the home page, and every time when I book a ticket there’s a small feature I enjoy so much I want to tell you about it: the buttons on the date selector are really, really tiny (16 × 8px). As you know thanks to Fitt‘s Law, there are even formulas to calculate how much better big buttons can be hit.

So I just added some padding. And that makes a huge difference: try to click on the same buttons later on in the booking process where the padding is missing.

If I could make one improvement I would add keyboard functionality to those buttons. Alas as the datepicker itself came from a third party, the assembled code was beyond my control. But I know that the Deutsche Bahn is listening to the needs of people with disabilities and their disability advisory board members are highly competent, so I trust these and other issues will be fixed soon …
