1
00:00:00.914 --> 00:00:02.171
It is a sound.

2
00:00:02.196 --> 00:00:03.805
Humans cannot feel sounds.

3
00:00:03.830 --> 00:00:06.003
But this one we also cannot hear.

4
00:00:06.028 --> 00:00:09.259
Yet dogs hear it,
bats use it to catch insects

5
00:00:09.284 --> 00:00:11.431
and dolphins use it for navigation.

6
00:00:11.457 --> 00:00:13.183
It is called ultrasound.

7
00:00:13.208 --> 00:00:16.565
Its frequency is too high
to be detected by the human ear.

8
00:00:16.589 --> 00:00:19.308
Yet we already use it to measure distance.

9
00:00:19.332 --> 00:00:22.271
In medicine for instance
we use it during pregnancies

10
00:00:22.296 --> 00:00:24.440
to check the health of the unborn baby.

11
00:00:24.465 --> 00:00:28.056
The SILENSE project
researches the application of ultrasound

12
00:00:28.083 --> 00:00:29.734
to recognize gestures.

13
00:00:29.759 --> 00:00:32.002
This could be used
to improve the communication

14
00:00:32.027 --> 00:00:33.827
between humans and machines

15
00:00:33.852 --> 00:00:36.681
such as cars or access to buildings.

16
00:00:36.706 --> 00:00:38.905
Our project also develops devices

17
00:00:38.930 --> 00:00:41.261
that shall improve
underwater communication.

18
00:00:41.286 --> 00:00:44.384
Since we do not hear ultrasound
it is sometimes hard

19
00:00:44.409 --> 00:00:47.853
to imagine these technological
developments to be real.

20
00:00:47.878 --> 00:00:50.237
Let’s take a look at how
this technology works

21
00:00:50.262 --> 00:00:53.290
and where it can positively
influence our daily life.

22
00:00:53.315 --> 00:00:55.749
Ultrasound can be used
for tracking gestures

23
00:00:55.774 --> 00:00:58.525
for easier operation
of household devices.

24
00:00:58.550 --> 00:01:00.973
For example lights, sun screens,

25
00:01:00.998 --> 00:01:05.291
but also for ultrasound communication
between smart devices in a room.

26
00:01:42.846 --> 00:01:46.393
Using SILENSE technology
to operate in-cabin systems

27
00:01:46.418 --> 00:01:49.620
of passenger cars can be easier
and more intuitive.

28
00:01:49.645 --> 00:01:52.875
No buttons would be needed for
human-machine interactions,

29
00:01:52.900 --> 00:01:55.568
so car interior design
can be more flexible

30
00:01:55.593 --> 00:01:58.519
to cater to all customer requirements.

31
00:02:04.798 --> 00:02:07.645
Access control to restricted areas
can be made possible

32
00:02:07.670 --> 00:02:10.956
by using ultrasound recognition
of human body motion

33
00:02:10.981 --> 00:02:14.773
with the specific gesture for opening
a door to the monitored area.

34
00:02:14.798 --> 00:02:19.194
Ultrasound allows an operation of
access systems without touching them.

35
00:02:19.219 --> 00:02:22.241
This will ensure high degree of
hygiene in hospitals,

36
00:02:22.266 --> 00:02:24.281
health centres and medical clinics.

37
00:02:24.306 --> 00:02:27.206
Patients could also call their doctor
with a simple gesture

38
00:02:27.233 --> 00:02:30.303
to avoid searching for the right
button and pressing it.

39
00:02:33.917 --> 00:02:36.663
Ultrasound can be used for more
than access control

40
00:02:36.688 --> 00:02:38.904
and gesture recognition systems however.

41
00:02:38.929 --> 00:02:41.193
Exclusively, only this technology

42
00:02:41.218 --> 00:02:43.963
can be effectively used for
underwater communication

43
00:02:43.988 --> 00:02:47.518
between devices, for example for
fitness training.

44
00:02:47.543 --> 00:02:49.245
Monitoring of swimmers performance

45
00:02:49.270 --> 00:02:53.127
can be done with smart bracelets
on their hands, body and legs.

46
00:02:53.152 --> 00:02:55.977
All linked to monitors
by the side of the pool.

47
00:02:56.002 --> 00:02:58.833
Using underwater ultrasound communication

48
00:02:58.858 --> 00:03:02.795
can also help locate divers during
diving courses in shallow water

49
00:03:02.820 --> 00:03:05.011
and navigate them back to their instructor

50
00:03:05.036 --> 00:03:07.713
when they get out of his line of sight.

51
00:03:07.738 --> 00:03:11.036
Ultrasound technology can have
many other applications

52
00:03:11.061 --> 00:03:13.277
which will make human life more comfortable

53
00:03:13.302 --> 00:03:16.025
and allow us to enjoy new experiences.

54
00:03:24.580 --> 00:03:26.852
All these technologies are
now in development

55
00:03:26.877 --> 00:03:29.269
at leading European research centres

56
00:03:29.295 --> 00:03:33.022
and industrial partners across Europe
within the SILENSE project.

57
00:03:33.047 --> 00:03:36.302
It is an ECSEL JU project

58
00:03:36.327 --> 00:03:40.420
and it brings together 32 partners
from 9 European countries.

59
00:03:40.445 --> 00:03:42.908
It started in May 2017

60
00:03:42.932 --> 00:03:46.997
and is also supported by
the respective National Authorities.
