Today’s invention is an application which makes airline meals a bit more interactive.
Before any food arrives, passengers (probably in business class only initially) could choose items using their seat-back touch screen, from a menu showing actual photographs of the meals.
If a particular dish had run out, the system would apologise and suggest alternatives.
Elements of the meal would, once touched, display data about calorie count, the chef who thought it up, its ethnic origin and statistics on how many people had chosen it.
On delivery, diners could then rate each item via the screen.
