In the session I talk about UX stumbling blocks and lessons learned when I developed a software for rear-projection screens and LED perimeter advertising systems for the local Basketball club. Even though I was developer, UX designer and user all in person, there were situations where I had problems using it under the time pressure of a home game, fueled by the fear of messing up in front of an audience of 6000 people.

for the Live Camera (aka „Lower Thirds“) „LiveTexter“ Most captions are prepared before the arena opens Some have to be typed „on the fly“, within seconds
Preview •Rear projection screens
1024 x 768 Pixels Scale down OK! Helps a lot •11 LED modules 11 x 768 = 8448 Pixels 80 Pixels high No good „at a glance“ solution for all modules
Be Absolutely Clear •If clicking
„something“ triggers a critical action, make this „something“ trivial to understand under heavy stress without even thinking.
Home vs. Guest •The official
name of a match: „Home vs. Guest“, e.g. Telekom Baskets Bonn vs. ALBA BERLIN •NBA naming: ALBA BERLIN at Telekom Baskets Bonn
Team Presentation •8 minutes before
tip-off: Lights out, loud music „Welcome to today‘s match!“ „Today‘s referees are...“ „Here are the players of ALBA BERLIN“ „Here‘s the Baskets Dance Team!“ „And now, here are your Telekom Baskets Bonn!“
Let‘s Look Again •What do
I want from a smooth transition? From content A to content B Within a certain timespan Too short not that different from a hard cut Too long timing not matching announcer‘s voice •Do I really need to control the speed? Experiments: 0.7 sec OK in most cases
Takeaways •Help users build up
confidence Don‘t be too subtle about state. If possible, provide a preview. Avoid internal translations: „Don‘t make me think“. •Decide if fine-grained control is necessary Don‘t sacrifice the usability of basic actions But don‘t take it away if users really need control.
