i + NEW TRENDS IN HARDWARE
Some hardware devices with new technology are already available, and some are in the process
of development. Let’s discuss some of them.
Wireless Devices
Earlier, all hardware devices were connected to the CPU box through a wire. These days, almost
every type of hardware has a wireless version available. They work with
the help of radio frequency (RF), infrared (IR), or Bluetooth technology.
Virtual Keyboard
A virtual keyboard is operated by typing on a detectable surface rather than
pressing physical keys. It is actually a software component because it is not a
physical part.
3D Camera
3D camera is a real-sense device that is able to recognise faces and
use that capability to log in to devices like smartphones or laptops. 3D
cameras can also measure distances between items or even scan objects
for 3D printing.
