For whatever reason, I still see a lot of web design on mobile devices fall into the trap of using buttons that align primarily with the left or right side of the screen. For a low to mid priority call to action, that may be okay but for your highest priority items, like Buy Tickets, you want to use a little UX knowledge to arrive at the best option.
To that end, I published the latest installment in the series of articles that gathers best practices user experience designers consider when building user interfaces. This one covers Fitt’s Law: the time to acquire a target is a function of the distance to and size of the target.
It includes plenty of examples and illustrations on how to find that sweet spot for high priority call to action items on mobile.
