2.2 HCI - Hardware considerations

What does HCI stand for?

• Human Computer Interaction

• High Capacity Interface

• Hardware Control Interface

• Home Computing Integration

What are the main types of displays?

• Touch screen, LCD, LED, OLED

• Plasma, LCD, OLED

• CRT, OLED, LED

• LED, OLED, Plasma

Which type of display allows the user to physically touch the screen as part of the interaction?

• LCD

• OLED

• Touch screen

• LED

What is the main advantage of LED displays?

• Thinner design

• Better contrast

• Low power consumption

• High color representation

How does an OLED display differ from LED/LCD displays?

• It produces its own light

• It uses more power

• It is thicker

• It cannot contain the touch response layer

What impact can a small display size have on the user's interaction with an HCI?

• It can make it difficult to use the HCI

• It allows for more options

• It improves the memory requirements

• It makes the HCI easier to use

What resource does an HCI need to use, including memory and processing power?

• Processing power only

• Memory only

• Display size only

• Memory and processing power

What happens if an HCI has a lot of options in terms of memory?

• It takes up less memory

• It affects the processing power

• It does not affect memory

• It takes up more memory

What is needed to complete the requested tasks when a user is communicating with an HCI?

• More interaction methods

• More processing power

• More memory

• More display options

What should be considered when designing an HCI?

• Only the cost of the device

• The size of display, cost of the device, method of interaction, processing power, and memory requirements

• Only the method of interaction

• Only the size of the display
