00:00:00,276 --> 00:00:05,580
Hi, guys! Today, we are going

2
00:00:05,580 --> 00:00:09,060
to read some information about different technological

3
00:00:09,060 --> 00:00:11,700
items that we, humans, have been using

4
00:00:11,730 --> 00:00:14,310
a long time. That's to say we're

5
00:00:14,310 --> 00:00:16,470
going to read about the evolution in

6
00:00:16,470 --> 00:00:19,529
the use of technology focusing on some

7
00:00:19,529 --> 00:00:20,160
items.

8
00:00:20,850 --> 00:00:22,650
First of all, I want you to

9
00:00:22,650 --> 00:00:24,960
know that you will have this presentation

10
00:00:25,020 --> 00:00:26,610
in your "Aula Virtual"

11
00:00:26,610 --> 00:00:28,170
to review what we are going to read

12
00:00:28,171 --> 00:00:30,960
now together. When you open this file

13
00:00:31,200 --> 00:00:32,970
you can go and read about those

14
00:00:32,970 --> 00:00:35,130
items in the order that you prefer.

15
00:00:35,520 --> 00:00:37,109
You just have to click on the item

16
00:00:37,112 --> 00:00:39,030
that you want and then the slide

17
00:00:39,060 --> 00:00:40,319
with information about

18
00:00:40,410 --> 00:00:42,720
this specific item will be open.

19
00:00:45,030 --> 00:00:47,970
Now, let's go through the presentation following

20
00:00:47,970 --> 00:00:50,459
the order of use by humans, now.

21
00:00:51,240 --> 00:00:53,970
By the 1920s radio programs were

22
00:00:53,970 --> 00:00:57,420
being broadcast into people's homes. TV came

23
00:00:57,420 --> 00:00:59,340
into use during the 1930s

24
00:00:59,400 --> 00:01:02,577
and the 1940s. The first electronic

25
00:01:02,577 --> 00:01:04,080
computers like the one you 

26
00:01:04,119 --> 00:01:05,940
see here on the right side corner

27
00:01:06,180 --> 00:01:08,309
were invented in the 1940s

28
00:01:08,309 --> 00:01:08,730
as well.

29
00:01:09,930 --> 00:01:12,300
Later in the 1900s electronic products

30
00:01:12,300 --> 00:01:15,450
became smaller and smaller as you can

31
00:01:15,450 --> 00:01:17,550
see here. Other  inventions in the

32
00:01:17,550 --> 00:01:20,640
late 1900s nineties were compact

33
00:01:20,640 --> 00:01:25,010
disc players, cellular telephones, digital cameras, and

34
00:01:25,010 --> 00:01:26,790
many other electronic products.

35
00:01:28,020 --> 00:01:30,960
Now, smartwatches. Many smartwatches

36
00:01:31,020 --> 00:01:34,041
are connected to our smartphones that notifies

37
00:01:34,041 --> 00:01:36,874
the users of incoming calls, e-mail 

38
00:01:36,874 --> 00:01:39,269
messages, and notifications from different

39
00:01:39,270 --> 00:01:42,410
applications that we use. Some smartwatches, like 

40
00:01:42,452 --> 00:01:43,890
the ones that I have  

41
00:01:43,890 --> 00:01:46,196
seen that you are using in school

42
00:01:46,350 --> 00:01:48,000
can even make phone calls.

43
00:01:49,650 --> 00:01:51,330
and, what about Augmented Reality? 

44
00:01:51,390 --> 00:01:54,150
What about that? This type of technology uses

45
00:01:54,151 --> 00:01:57,210
computer-generated visual and auditory media on

46
00:01:57,210 --> 00:01:59,903
the physical world. The purpose of Augmented 

47
00:01:59,908 --> 00:02:01,530
 Reality is to create an

48
00:02:01,530 --> 00:02:04,290
interactive experience. Have you ever tried that?

49
00:02:05,220 --> 00:02:06,990
What about other  different technology items?

50
00:02:06,990 --> 00:02:09,270
Now, please, tell me

51
00:02:09,870 --> 00:02:12,090
 about those items that

52
00:02:12,095 --> 00:02:14,160
you have used in your daily life

53
00:02:14,610 --> 00:02:16,860
using the forum that I have opened

54
00:02:17,070 --> 00:02:18,422
in the section 

55
00:02:18,513 --> 00:02:20,339
for this unit in the "Aula Virtual"

56
00:02:20,339 --> 00:02:22,380
See you in the class!!

57
00:02:22,440 --> 00:02:22,980
Bye, bye!
