LESSON 4

 

MAN-MACHINE INTERFACE

1. Life in the automated factory is based on communicati­ons. Sensors gather data, computers send commands, PCs control machines, and management makes decisions based on data from these devices. Sensors, computers, processors, and man must all talk to each other.

2. There have been a number of recent developments in mac­hine-to-machine interfaces. Networks, hardware, and soft­ware that allow various processors to share and exchange data, are moving into the factory. These networks are con­necting whole processes together, allowing more flexibility and control of manufacturing.

3. A major problem with networks, though, is interfacing processors that do not use the same language. Rules are being developed that will make it easier for these different proces­sors to communicate.

4. Man-to-machine communications have seen dramatic de­velopments. The computer is no longer an unyielding, unfor­giving device that insists you conform to its method of work­ing. The computer has become friendly, even inviting. Com­plex mnemonics and performing functions in a specific sequ­ence have been replaced with graphic representations   of commands and a cursor device known as a mouse. Now, get­ting a computer to perform a function is as easy as pointing your finger to the graphic representation of the function you want performed and pressing a button on the mouse. And programs exist for all types of business needs including tea­ching someone unfamiliar with computers how to run one.

5. A new technology that's also making it easier for man to interface with machines is speech recognition. Here, you enter information into a machine with your voice; a device in the machine translates the sounds into signals the compu­ter or machine can work with. This method of entering data is faster and more accurate than using a keyboard to enter information.

 

Exercise 1. Find the synonyms in the text to the following words:

1. collect (1)                                                                  5. correspond (4)

2. basic (3)                                                                     6. instruction (4)                                                                   

3. to simplify (3)                                                           7. link (2).  

4. unknown (4)                                                          

 

Exercise 2. Give the Ukrainian equivalents to the following words and word-combinations:

1. speech recognition

2. machine – to – machine interface

3. business needs

4. control machines

5. networks

6. hardware and software

7. cursor device

8. sequence.

 

Exercise 3. Say if the statements re true or false:

1. A man shouldn’t talk to sensors, computers, processors.

2. The networks connect the whole process in the automated factory.

3. The computer is no longer an unyielding, unforgiving but even inviting device.

4. Graphic representations of commands haven’t replaced performing functions in as specific sequence.

5. A new technology of speech recognition allows enter information into machine with your voice.
