All Things About Industrial Pointing Devices Every Industry Needs To Know

Modern industrial applications are being implemented in various industry sectors. For example, the food industry uses conveyor belts controlled by advanced computing equipment for large-scale operations. Distribution agencies, such as Amazon, take advantage of warehouse robots for logistics applications.

Although each of this industry has different applications, it all has one purpose; to maximise its productivity. This is the main reason why these industries installed the most suitable computer technology for these operations. Read more: http://bit.ly/IndustrialPointingDevices

Why Use TB38 Industrial Pointing Device With Air Traffic Control PCs

Technical issues may occur in most industries like in the aviation centres. In December 2013, technical issues at the air traffic control centre in Swanwick, Hampshire led to the delay of over 1,000 flights. As a result, over 225 flights were cancelled. It prompted the National Air Traffic Service (NATS) to take control of the situation and resolve the said issue.

This incident highlighted the need to upgrade the current air traffic system and install rugged computers with reliable computer peripherals. And, amongst the most recommended industrial pointing device for this application is the TB38 Series Trackerball. Read more: https://bit.ly/2u3hqBN

1.2) Input Devices- keyboards and pointing devices.

Students should be able to: evaluate a range of input and output devices:  keyboards, pointing devices, smart cards, bar codes, OMR, MICR, ATM, touch screen, printers, plotters, monitors, scanner, sensors, interactive white board, data projectors, OCR, speech input, speech output and actuators;

Keyboards:

Have keys which when pressed send digital code to the computer which gives computers commands.

4 groups of keys on QWERTY keyboard are:

Numeric

Function

Cursor

Alphabetic

Concept keyboard

Overlays on keyboard with text or pictures.

Keys sensitive aresa of a plastic surface.

Easy to operate.

Use in a restaurant.

Advantages:

Fast input of data

can be wiped clean.

Limited choices so less chance of making mistakes.

Mouse

Has a rotating ball.

Movement detected by sensors.

hand used to move mouse on flat surface making cursor correspond.

When a button is pressed it sends signal to the computer.

Trackerball

Like an upside down mouse, stays still, the user moves the ball and is used on laptop computers.

Touch Sensitive Pad (Tracker Pad)

The screen is an input and output device.

The screen is covered by a membrane/ a line of infrared sensors/ along the edges of the screen which is sensitive to pressure.

The pressure of the users finger is detected.

The finger cuts the beam and an X and Y position is calculated.

Joystick

As the stick is moved forwards/ backwards/ left/ right the movement is detected by sensors/ switches which detect the X and Y coordinates of the stick.

A sensor detects the depression of the button.

the signals from the sensors are input to the computer.

AD (Analogue-->Digital) conversion may be used.
