Technological Improvements

Hardware has been improving with the years and they can change the things we do in a radical way.

• Joystick Evolution

Modern Joystick

Atari Joystick

Ralph H. Baer, inventor of television video games and the Magnavox Odyssey console, released in 1972, created the first video game joysticks in 1967. They were able to control the horizontal and vertical position of a spot displayed on a screen. The earliest known electronic game joystick to be available commercially was released by Sega as part of their 1969 arcade game Missile, a shooter simulation game that used a two-way joystick with a single "fire" button to target and shoot oncoming planes displayed on a projection screen.

Know Joysticks can simulate real flights and are useful for training pilots because when they are learning they do not need to flight real jets or helicopters when they are novices and also they save money because real flights cost.

We can say that a device first used for gaming know has evolved to a very useful thing because we can take advantages of it in many aspects like I already said.

• Keyboard Evolution

A keyboard originally initiated as a device which triggered electronic switches through an arrange of keys that acted as a mechanical lever.

Today we got ergonomic keyboard that are devices made for the prevention of hand diseases caused by prolonged computing sessions.

Technology has advanced a lot in the last ten years and a touchless keyboard has been developed for disabled peole here is the link of a Gizmodo talking about the device.

• Speakers Evolution

 With the past of the time smaller high fidelity speakers have been developed and the are available at an affordable price in most computer or music shops.

They make the gaming or watching  movies a whole different experience.

Also portable Speakers have been developed and their benefits are that you can enjoy music everywhere and they use rechargable batteries so you do not spend on batteries or disposable batteries so you can enjoy music on the go without the hassle of charging times
