Carrying objects on one’s head is a time-honored method of moving heavy objects (https://en.wikipedia.org/wiki/Head-carrying).
However, this is—surprisingly—not a common technique in the Western world.
Commuters use all sorts of briefcases, laptop bags, backpacks, and messenger bags, but there’s no such thing as a “laptop hat.”
This proposal is fairly self-explanatory: a “laptop hat” (Figure 1).
One issue with this laptop hat is that it can easily slip off the user’s head. However, it’s common for head-carrying individuals to use one hand to steady the load. Although this does occupy one arm, that makes the laptop hat’s efficiency equal to that of a briefcase (which also requires the use of one arm).
It might be possible to free the user’s hands completely by mounting the laptop attachment on top of a sturdier type of headwear, such as a motorcycle helmet.
PROS: May make commutes easier for laptop-carrying professionals. Could free up a hand that would otherwise be used to carry a briefcase or laptop bag.
CONS: The reflective metal of the laptop could attract magpies and other birds to attack the wearer.
