Last week, we reported about Facebook's efforts to develop a system to permit people to type "directly with their brains." Such technology could help hundreds of millions of people who cannot read or write get their thoughts in print. It could also make communication easier for people with limited movement ability.

The possibility is interesting. But it is far from the only plan announced last week at the Facebook's developers' conference, or F8.Facebook officials also offered similarly wild ideas. How about technology that permits you to hear with your skin instead of your ears, for example. Or maybe you would be more into a system that lets you playing games and visiting your friends in augmented and virtual reality.

Facebook says it plans to make these activities a reality within the next 10 years.Or not. Not every Facebook venture is a success. You do not see many Facebook phone users, for example.

Hearing with your skin
Some day we may tell our grandchildren that we used to hear through our ears. That is because Facebook might make it possible for use to hear through our skin.

This technology could help people with limited or no hearing ability.
Facebook hopes to have your skin hear the same way your ears hear. The company says one test subject was able to hear nine words through her skin.
Facebook augmented reality
Facebook wants to improve your reality by adding to it through the use of special glasses. The glasses are designed to show users things that are not physically present.

You could be sitting in your living room, looking at an empty table, then put on Facebook glasses and see a chess set on that table. You and a friend could play chess on that set using Facebook glasses, as if you were sitting across the table from each other.

You could also control what your friends are seeing when you live stream video to them on Facebook Live. Add an image of a cup of coffee to your table. Make it steaming hot. Then, add a second cup so you do not look as if you are alone.

Facebook says you will be able to add frames, sports equipment, drawings and more to your videos and photos. It says you could even create your own frames to share.

Facebook Spaces - Virtual Reality
Facebook Spaces is a new virtual reality tool designed to let users hang out with their friends around the world, as if they are together in the same place.
Spaces will use avatars people create from a photo of themselves on Facebook. These avatars will appear in Spaces so you can hang out with kind of a cartoon version of your friends.

You view Spaces through a virtual reality viewer and can invite others via Facebook Messenger. Spaces lets you visit with your friends in virtual places around the world.A video shows how Spaces lets friends get together in virtual worlds.
