1
00:00:00,630 --> 00:00:02,650
How does augmented reality work.

2
00:00:04,210 --> 00:00:09,220
What is augmented reality for many of us implies a technical side.

3
00:00:09,220 --> 00:00:11,560
How does it work.

4
00:00:12,420 --> 00:00:22,320
For a ah a certain range of data images animations videos 3D models and other things may be used and

5
00:00:22,320 --> 00:00:29,650
people will see the result in both natural and synthetic light also.

6
00:00:29,670 --> 00:00:38,940
Users are aware of being in the real world which is advanced by computer vision unlike in VR they are

7
00:00:38,940 --> 00:00:48,420
can be displayed on various devices such as screens glasses handheld devices mobile phones had or had

8
00:00:48,420 --> 00:00:53,880
mounted displays now.

9
00:00:53,990 --> 00:01:02,450
It involves technologies like slam which is simulates localization and mapping depth tracking which

10
00:01:02,450 --> 00:01:04,310
is briefly a sensor data.

11
00:01:04,310 --> 00:01:12,770
Calculating the distance to the objects and the following components such as cameras and sensors processing

12
00:01:12,980 --> 00:01:22,510
projections and reflection what we are going to apply in this course will include camera or cameras

13
00:01:22,630 --> 00:01:32,020
and sensors and it will be using your very own mobile phones in order to apply augmented reality and

14
00:01:32,020 --> 00:01:38,950
to start playing with objects with your own hand in the air or environment that you are going to create

15
00:01:39,400 --> 00:01:41,700
inside your home.

16
00:01:41,830 --> 00:01:50,230
Now when it comes to cameras and sensors cameras and sensors are used to collecting data about users

17
00:01:50,290 --> 00:01:59,560
interaction and sending it for processing cameras on devices are scanning the surrounding and with this

18
00:01:59,560 --> 00:02:06,540
information a device locates physical objects and generates 3D models.

19
00:02:06,650 --> 00:02:15,200
It may be special duty cameras like in Microsoft tolerance or common smartphone cameras which we use

20
00:02:15,200 --> 00:02:17,150
to take pictures and videos.

21
00:02:19,880 --> 00:02:27,830
When it comes to processing our devices eventually should act like little computers something modern

22
00:02:27,950 --> 00:02:31,780
smartphone already do in the same manner.

23
00:02:31,790 --> 00:02:42,710
They require a CPR you a GP you flash memory RAM Bluetooth or Wi-Fi as you beat us and other built in

24
00:02:42,710 --> 00:02:53,570
devices to be able to measure speed angle the direction orientation in space and so on when it comes

25
00:02:53,570 --> 00:02:55,460
to projection.

26
00:02:55,460 --> 00:03:03,740
This refers to a miniature projector on our headset which takes data from sensors and projects digital

27
00:03:03,740 --> 00:03:10,710
content which is the result of processing onto our surface to view the use of projections.

28
00:03:10,710 --> 00:03:19,530
An hour has not been fully invented yet to use it in commercial products or services but we are going

29
00:03:19,530 --> 00:03:26,120
to use our own mobile device for projection when it comes to reflection.

30
00:03:26,130 --> 00:03:32,610
Some other devices have mirrors to assist human eyes to view virtual images.

31
00:03:32,610 --> 00:03:39,660
Some have an array of small curved mirrors and some have a double sided mirror to reflect light to a

32
00:03:39,660 --> 00:03:43,070
camera and to our users eye.

33
00:03:43,110 --> 00:03:50,900
The goal of such reflection baths is to perform a proper image aligned again.

34
00:03:50,940 --> 00:03:58,080
All of these are covered in the practical section where we are going to create a homemade augmented

35
00:03:58,080 --> 00:04:00,120
reality experience.

36
00:04:00,120 --> 00:04:01,650
Thanks for watching this lesson.

37
00:04:01,650 --> 00:04:07,730
If you have any question regarding any of these components please ask in the here and labeled.

38
00:04:07,740 --> 00:04:10,410
