Bugs in the Wild: In Flight Edition

Posted by Steve on August 29, 2008

I was recently on an air canada flight down to San Francisco to visit my parents and I had a touch screen in flight entertainment system (here is a link to a picture if you want to see).

The first thing that I start with is simply watching a TV show, as I wanted to relax a little, but as the flight progressed I decided to see what the entertainment system had to offer. I notice there is an option to listen to music, so I navigate over to there and start setting up a playlist. This is where I noticed the problem. The whole playlist (if it is over 5 songs long) does not fit on the screen, therefore there are arrows that you can click on to go up and down on the playlist; and if you get to the top or bottom of the playlist the respective up or down arrow gets disabled. Makes sense, why would you need to go up anymore if you are at the top of the playlist, right? Because of the title of the post, obviously this is wrong! What they forgot to take into account is that when you click on song that is at the bottom of those displayed on the screen, the screen re-centres around that song, thus if you click the fourth song on the list, you can no longer see the first song, and at this point in time the go up arrow is also still disabled!

There is of course a fix to this, you can simply click the down arrow and the up arrow will fix itself, but if you were really malicious you could have so that both arrows got diabled and you would have to exit and re-enter the audio screen.

I thought this was a fun little bug in a real world situation.
