1
personal computers have become smaller yet increasingly more powerful today many daily
2
Early activities involve mobile communication and computer access both in and outside the home.
3
For some inventors, the next step is to integrate computers into accessories or into smart clothing, thus creating wearable computers.
4
Martin Kelly reports.
5
The concept of wearable computers is hardly innovative.
6
Early attempts at manufacturing them produced clumsy results.
7
The wearer had to wrap himself in wires
8
or strap a strange -looking device to his forehead and carry a backpack of computer equipment.
9
The technology didn't sell because in today's world, appearance is everything.
10
However, today's wearable computers may provide the solution.
11
Professor Tanya Carter is here to tell us more.
12
Wearable technology is evolving so fast that it has become not only extremely convenient, but a fashion statement too. For example,
13
handheld computers have been miniaturized enough to be strapped to the wrist like a watch not much larger than the average chronometer.
14
Though limited in applications, it is only a matter of time before the watch has full computing capacity.
15
This could eliminate the need to carry a laptop.
16
And rather than attaching all kinds of objects to a jacket, researchers are creating state -of -the -art textiles with electronics built in.
17
One such textile is composed of small patches of fabric into which minuscule computer chips have been embedded.
18
These patches are assembled with Velcro that conducts electricity to create a purse similar in appearance to an ordinary leather purse.
19
This purse provides you with information, such as the latest weather forecast.
20
It can also keep track of your wallet via a minute radio signaling chip attached to the wallet.
21
Sensors integrated into the purse's fabric transmit a message to alert you if the wallet is not inside.
22
This purse even allows you to upload your favorite music onto your music player, which, incidentally, could soon be inside your scarf.
23
I understand that scientists are creating accessories, but there are other innovations in the field of computer -integrated clothing, right?
24
What kind of initiatives are underway to adapt wearable computers for use in fields like health and emergency services?
25
Well, as monitors, wearable computers have many applications.
26
For example, a smart armband registers data about the wearer's physical condition.
27
It can help people lose weight by telling them how many calories they're burning at any given time during exercise.
28
Doctors could also use it to monitor the well -being of the elderly and infants, too.
29
One ingenious adaptation is a shirt made of a special fabric that has the capacity to analyze the wearer's heart rate,
30
respiration, and other key health indicators.
31
For example, it is being used today in medical research to examine the effectiveness of certain new heart treatments.
32
And since it can measure stress levels and body heat,
33
it could be used to monitor firefighters at a blaze or to allow a mother to check on her asthmatic child.
34
Another wearable item
35
that has proved remarkably helpful to runners who want to keep
36
fit is a sensor embedded into the sole of their running shoes.
37
The sensor relays information about the speed
38
and the distance you've covered to your iPod
39
and can change the music track to another song with a faster or slower tempo, thus encouraging you to accelerate your pace or reduce your speed.
40
The sensor is invisible and the earphones are the same as the ones on a regular iPod.
41
So fashion -wise, the wearer would not feel conspicuous.
42
Obviously, as technology advances, so will the wearable computer.
43
Ultimately, it could be a smart assistant that goes wherever we go, registering and analyzing data about us and our environment.
44
Number 1.
45
Why were the first wearable computers unsuccessful?
46

53
Why are wearable computers useful in fitness training?
54
The wearer had to wrap himself in wires
55
or strap a strange -looking device to his forehead and carry a backpack of computer equipment.
56
The technology didn't sell because in today's world, appearance is everything.
57

58
It can also keep track of your wallet via a minute radio signaling chip attached to the wallet.
59
Sensors integrated into the purse's fabric transmit a message to alert you if the wallet is not inside.
60
For example, it is being used today in medical research to examine the effectiveness of certain new heart treatments.
61

Vocabolario e note di pronuncia per questa lezione

Questo video contiene 66 frasi e 810 parole da ripetere con lo shadowing. Il parlato dura 8:04. Chi parla lo fa lentamente, circa 100 parole al minuto, quindi c’è tempo per imitare ogni suono. Solo il 74% delle parole rientra nelle 3.000 più comuni dell’inglese, quindi il lessico è impegnativo.

La grammatica di questo video

Le strutture che chi parla usa di più, con le parole esatte del video:

StrutturaNel video
Present perfect have/has + participio passato — un’azione passata che conta ancora adessohave become · has become · have been miniaturized
Forma passiva be + participio passato — conta ciò che accade, non chi lo fahave been miniaturized · is composed · are assembled

Pronuncia a cui fare attenzione

Chi parla usa 5 contrazioni e forme ridotte, come didn't, you've, they're. Pronunciale nella forma breve, così come le senti.

  • I suoni “th”: clothing /ˈkloʊðɪŋ/, leather /ˈlɛðɚ/
  • I suoni “sh” e “zh”: shoe /ˈʃu/, unusual /ʌnˈjuːʒ(u)əl/, initiative /ɪˈnɪʃ.ə.tɪv/, innovation /ˌɪn.əˈveɪ.ʃən/, adaptation /ˌæd.æpˈteɪ.ʃən/
  • Parole lunghe — attenzione all’accento: effectiveness /ɪˈfɛk.tɪv.nɪs/, remarkably /ɹɪˈmɑɹkəbli/, accessory /əkˈsɛs.(ə.)ɹi/, unusual /ʌnˈjuːʒ(u)əl/, electricity /ɪˌlɛkˈtɹɪsɪti/

I suoni difficili per chi parla italiano:

  • /h/ — va soffiata, non è muta: helpful /ˈhɛlp.fl̩/, forehead /ˈfɔɹ.hɛd/, wherever /(h)wɛɹˈɛvɚ/
  • Consonante finale — senza aggiungere una vocale dopo: wallet /ˈwɑl.ət/, purse /pɚs/, fabric /ˈfæb.ɹɪk/, integrate /ˈɪn.tɪ.ɡɹeɪt/, chip /t͡ʃɪp/
  • /æ/ — più aperta della “e”: fabric /ˈfæb.ɹɪk/, strap /stɹæp/, attach /əˈtæt͡ʃ/, patch /pæt͡ʃ/, wrap /ɹæp/

Come esercitarsi con questo video

  1. Ascolta tutto il video una volta senza parlare e annota le parole che non conosci.
  2. Fai shadowing frase per frase a velocità normale, ripetendo ognuna finché il tuo ritmo coincide con quello di chi parla.
  3. Registrati e confronta con l’originale, facendo attenzione a parole come sensor, wallet, purse.

Cos'è la tecnica dello Shadowing?

Shadowing è una tecnica di apprendimento delle lingue supportata da studi scientifici, originariamente sviluppata per la formazione dei traduttori professionisti e resa popolare dal poliglotta Dr. Alexander Arguelles. Il metodo è semplice ma potente: ascolti un audio in inglese di madrelingua e lo ripeti immediatamente ad alta voce — come un'ombra che segue il parlante con un ritardo di solo 1–2 secondi. A differenza dell'ascolto passivo o degli esercizi di grammatica, lo shadowing costringe il tuo cervello e i muscoli della bocca a elaborare e riprodurre simultaneamente i modelli di discorso reale. La ricerca dimostra che migliora significativamente la precisione della pronuncia, l'intonazione, il ritmo, il discorso connesso, la comprensione dell'ascolto e la fluidità del parlato — rendendolo uno dei metodi più efficaci per la preparazione alla prova di speaking dell'IELTS e per la comunicazione reale in inglese.
