We can think of making an automatic table lamp using IR sensors. IR sensors will detect the person sitting in front of the table. And only if the obstacle is ahead of it, the table lamp will be Turn On. i.e. the if the person is in front of the table, the lamp will be ON and will be turned OFF as soon as the person gets off from the table or dozes off.
