The document describes several potential future technologies: 1. Tiny lasers that project images directly onto a person's retina, allowing images to be overlaid on their normal vision. 2. Electronic circuits printed on skin that, combined with active contact lenses, would allow a person to access the internet or call friends by touching their skin and seeing responses in the lens. 3. Jewelry-like devices that recognize voice commands and allow calling others with a word. The document asks which of these inventions might most benefit society and how. It provides vocabulary words and examples of their uses.

1. Unit 14

2. What’s the main idea?
•It’s like a contact lens but tiny lasers
project a picture onto your retina.
The picture will be included in your
normal retina.
•Electronic circuits will be printed on
your skin. When combined with
active contact lenses, you can touch
your skin to access the internet or
call a friend and see them in the lens.

3. •It looks like jewellery but will
connect and dial someone when
you say a word because of voice
recognition.
•Solar panels covering 10% of the
Sahara desert could supply energy
to the rest of Africa and the world
using superconducting cables.

4. •Self-driving cars would run on
electrified rails all over the country.
You’ll tell the car where to go and
relax while it gets on the rails, then
off the rails and drives you to your
destination.
•Probes would collect signals from
your brain, put them in a brain model,
speed up the thought processes, then
put them back into your brain -
making you super-intelligent.
