The impact of HCI on Economy

Productivity of an individual:
one impact that HCI has had on the economy is that it has increasing the productivity of an individual by speeding up input, an example of how HCI has speed up input is the barcode readers used in super markets and shopping centres, barcode readers increases the productivity of an individual because the cashiers don't have to entre in the barcode number manually which allows the super market markets and shopping centres to sell more items and make more money.

Automation:
Another impact that HCI has had on the economy is the increasing automation in factories and other workplaces by reducing the amount of human input required by the worker by installing more efficient input devices such as computers.
one way that automation has affected the economy is that as more and more employees are being replaced by automated systems or have to learn how to operate which can create, assemble and package products faster than a normal worker could, this means that less and less jobs there are available for people and the unemployment rate goes up.
Another way that automation has affected the economy is that the companies will be saving money as they will not have to pay wages to as many or in some cases any employees but as the company is saving money the company's products will be cheaper to buy.

the affect that mobile phones have had on the economy is that they have created massive competition against companies that create mobile phones, these companies try to outdo
