I am a frequent flyer of British Airways. I like the service and the timing of their flight so I make sure I travel with them.
Many airlines offer In-flight entertainment (IFE) with video-on-demand (VOD). It seems most of which run Linux (look here and here for examples). those IFEs are usually based on touch-screens that allow direct interaction.
The system on BA allows the variety of choice of what to watch: new releases, comedy, action, shows, kids .. etc. After several attempts to “complete a task” I noticed a problem with the interface design, unfortunately I was too lazy to stand up, grab my bag, take out the camera, and snap a photo, so I suppose an illustration will suffice.
British Airways VOD Interface Design
As can be noticed from my high-tech illustration, even though the listing has enough spacing between them to be able to click on each easily without much concentration, there is a problem when trying to click the “next” button located on the bottom of the screen. Clicking on the “next” button requires a high level of concentration and because of various issues such as the turbulence and the condition of the touch-screen (being used by so many different people) the accuracy is low. I actually tried clicking on it several times before I go it right. A simple solution might be to move the bottom row buttons a bit lower; if I remember correctly there is enough space for that. However, the reason of not moving them lower might have to do with the quality of the touch-screen; not being that responsive on the edges.
An alternative solution would be to redesign the listing to better utilize the area and allow for easy clicking. One way of doing it would be like this second illustration. This allows for a larger clickable area without decreasing the amount of information displayed.
Video-on-Demand Redesign Alternative
A third and final alternative could be like the following illustration. This second alternative layout places the movie titles the same as the current design, however, it moves the context buttons (back, next, main menu) buttons to the right of the screen which allows greater space for the movie titles and separates context buttons.

Now I really wish I did take that photo so that I can have some more insight for a redesign. Maybe next time.
