I’ve noticed more use of automatic lights in office buildings. They detect movement and, when the room is empty, turn themselves off.

They are more efficient and save money. If, however, like me, you tend to pause and think during the day, they can be a bit annoying.

• Head down, I can be typing and the light will go off.
• Thinking things through, looking at the ceiling, the lights will go off.
• Reading from a book (old-school), the lights will go off.

There then follows automatic light aerobics as we wave and jump about to bring the light back.

Does it really improve things?

The next time you’re thinking about automating some of your learning content, just pause. Do people do automatic learning aerobics to work around your more ‘efficient’ systems?
