2 English for Information Technology A2-B1 Vocational English Teacher’s Book

• OCR (Optical Character Recognition) software, 

 

which converts images, perhaps from the 

 

device’s camera, to data (words, characters, 

 

numbers, etc.) that a computer can understand 

 and 

use. 

• Accelerometer, which detects and measures 

 

motion – for example, if the device is dropped or 

 

rotated. It is this that enables tablets and 

 

smartphones to change the orientation of the 

 

screen as it is turned around. Accelerometers 

 

should not be confused with motion sensors: 

 

accelerometers detect motion of themselves, 

 

whereas motion detectors are stationary and 

 

detect motion of other bodies. Motion sensors 

 

are used, for example, in burglar alarms.  

 

Email 

Most students will already be familiar with email in 

their own language. In case students ask, the 

screenshots from the unit are based on the Mozilla 

Thunderbird email.  

In the screenshot, CC stands for ‘Carbon Copy’ and 

BCC stands for ‘Blind Carbon Copy’. 

 

 

 

 

Business matters  

This involves a scenario in which students prepare a 

proposal to upgrade the electronic communications 

systems of an architecture firm. It applies the key 

vocabulary and grammar of this unit.
