Touchscreens, Printers, & Cameras

As their name implies, (a)   touchscreens rely on the resistance, or pressure, that's applied to the screen itself.

Resistive touchscreens consist of two thin layers of transparent material.

The top layer is made of flexible ​ (a)   , and the bottom layer is typically made of ​ (b)  

• metal
• harder plastic
• rubber
• plastic film
• glass.

The flexible top layer of a resistive touchscreen bends down and touches the glass layer when the user...

• uses a mouse
• gives a voice command
• uses an IR remote control
• presses on the touchscreen

This picture illustrates what kind of touchscreen?

• Resistive touchscreen
• Capacitive touchscreen

Capacitive touchscreens work because the human body...

(a)  

When a conductive finger touches the screen, it creates a change in

(a)   . ​ (b)   under the screen detect the location of the change, which the computer translates into instructions.

• voltage
• wattage
• Photoreceptors
• Sensors
• Spacer dots

This picture illustrates what kind of touchscreen?

• Resistive touchscreen
• Capacitive touchscreen

Smartphones typically use _________ touchscreens.

• Resistive
• Capacitive

Match the ADVANTAGE to its kind of touchscreen.

Groups:

(a) RESISTIVE

,

(b) CAPACITIVE

• Can sense any object touching the screen

• Fewer accidental touches

• Sensitive to light touch

• Better survival against rough handling

• Cheaper to manufacture

• Sharper images

Workers in many industries, such as manufacturing and medicine, are required to wear gloves. Since _______ touchscreens can sense any object that touches with enough pressure, they're ideal for these situations.

• resistive
• capacitive
