0:00:02 > 0:00:03CHATTERING
0:00:09 > 0:00:11Oh, no sugar.
0:00:27 > 0:00:30This week on Click we're putting you right in the middle of the action
0:00:30 > 0:00:32without leaving your seat.
0:00:32 > 0:00:34You will need the goggles though.
0:00:34 > 0:00:38We're at the Commonwealth Games where, for the first time ever,
0:00:38 > 0:00:41360 degree footage of a major sporting event
0:00:41 > 0:00:46is being live streamed to a virtual reality headset.
0:00:46 > 0:00:49If that's the future of watching sport, we'll also be looking at
0:00:49 > 0:00:54experiments exploring the use of VR to create immersive journalism.
0:00:54 > 0:00:58Our dreams become reality as we sit down with screen legend
0:00:58 > 0:01:03and sci-fi queen Sigourney Weaver to talk about her latest role.
0:01:03 > 0:01:06Hint - may contain aliens.
0:01:06 > 0:01:10And we'll look at how to plan your latest journey in Webscape.
0:01:15 > 0:01:17Welcome to Click. I'm Spencer Kelly.
0:01:17 > 0:01:20And welcome to the BBC's Broadcasting House in London.
0:01:20 > 0:01:24But what does the future of TV look like?
0:01:24 > 0:01:26Back in the '80s, the futurologists were telling us
0:01:26 > 0:01:28that one day we'd all be wearing one of these,
0:01:28 > 0:01:32exploring our own virtual worlds from the comfort of our own homes.
0:01:32 > 0:01:35The problem was back then VR was rubbish.
0:01:36 > 0:01:40So it went away, but not, as it turns out, for good.
0:01:40 > 0:01:44These days the displays inside the goggles are much better
0:01:44 > 0:01:47and the motion sensing technology is far more responsive,
0:01:47 > 0:01:50and that means virtual reality is back.
0:01:50 > 0:01:53And it's not just being used in video games.
0:01:53 > 0:01:56Dan Simmons has been to the Commonwealth Games in Scotland
0:01:56 > 0:01:58to witness a world first,
0:01:58 > 0:02:03where the BBC is attempting to give you a ringside seat.
0:02:05 > 0:02:08It's the biggest sporting event Scotland has ever hosted.
0:02:08 > 0:02:12And for those responsible for broadcasting the Commonwealth Games
0:02:12 > 0:02:15the aim is not solely to show what's here,
0:02:15 > 0:02:20it's to make some lucky people feel that they are.
0:02:20 > 0:02:24Inside the Hydro arena, camera operators have been practising
0:02:24 > 0:02:28their own floor routines to ensure smooth coverage of the gymnastics.
0:02:28 > 0:02:31But Stephen from the BBC's R&D team
0:02:31 > 0:02:34is setting up a different kind of kit.
0:02:34 > 0:02:37He's capturing and then sending a live,
0:02:37 > 0:02:41360 degree video signal out of the arena.
0:02:41 > 0:02:45To capture it all this camera has seven lenses.
0:02:45 > 0:02:48Six around the side and one on the top.
0:02:48 > 0:02:52Special software stitches together the seven video feeds on
0:02:52 > 0:02:55the fly to create an image like this.
0:02:56 > 0:03:00And to capture the roars and cheers a spatial audio microphone records
0:03:00 > 0:03:03the sound from all directions.
0:03:06 > 0:03:09The action in the Hydro is streamed live over the internet
0:03:09 > 0:03:12to the Science Centre, in this case just half a mile away.
0:03:12 > 0:03:15But, of course, theoretically, viewers could be anywhere
0:03:15 > 0:03:18with a stable internet connection.
0:03:19 > 0:03:22The camera's been deliberately positioned at head height to
0:03:22 > 0:03:27give viewers a realistic idea of what it would be like to attend the event.
0:03:27 > 0:03:30They did think about putting the camera above the action
0:03:30 > 0:03:32or right in the middle of the floor,
0:03:32 > 0:03:35but they found that that made people feel a bit dizzy.
0:03:35 > 0:03:39Just how realistic will this be?
0:03:39 > 0:03:41Oh!
0:03:41 > 0:03:45I just heard a roar there.
0:03:45 > 0:03:48It's really cool. It's weird.
0:03:48 > 0:03:50That's amazing.
0:03:51 > 0:03:52Ach, strewth!
0:03:54 > 0:03:56This is where the magic happens.
0:03:56 > 0:04:00Creating the illusion that you're actually there
0:04:00 > 0:04:02are two screens inside the headset
0:04:02 > 0:04:06that show a small section of that 360 degree video.
0:04:06 > 0:04:09Motion sensors work out your head movements to show you
0:04:09 > 0:04:12what you'd be looking at as if you were there.
0:04:14 > 0:04:17We've seen surround vision cameras before,
0:04:17 > 0:04:20but getting the footage to the audiences live,
0:04:20 > 0:04:24with minimal time-lag, around three or four seconds,
0:04:24 > 0:04:25is the impressive part.
0:04:25 > 0:04:27There's a trade-off there.
0:04:27 > 0:04:30The engineers have found that the quality of the video
0:04:30 > 0:04:33needs to be reduced so it can be stitched together faster
0:04:33 > 0:04:35and sent across the net.
0:04:35 > 0:04:38So the picture isn't as sharp as we're used to.
0:04:39 > 0:04:44A problem exacerbated by the fact the screen is so close to our eyes.
0:04:44 > 0:04:48In future, higher-powered processing and more bandwidth for each viewer
0:04:48 > 0:04:50could allow for more detail.
0:04:50 > 0:04:55For now, getting a smooth, reliable feed is more important.
0:04:55 > 0:04:59This is the first time that a major sporting event
0:04:59 > 0:05:02has been streamed live to a VR headset,
0:05:02 > 0:05:05something that could be an everyday reality in the future.
0:05:05 > 0:05:10We're sending the sound in a special format that lets us move that
0:05:10 > 0:05:13when you move your head.
0:05:13 > 0:05:16That can really add to the experience cos you'll hear something
0:05:16 > 0:05:19that happens over your shoulder
0:05:19 > 0:05:23and turn your head to look and see what's going on.
0:05:23 > 0:05:27People usually just think of the video side of things,
0:05:27 > 0:05:29but the audio really adds to the experience.
0:05:29 > 0:05:31You can see everything.
0:05:31 > 0:05:33HE CHUCKLES
0:05:33 > 0:05:36We're running it in real-time so that we can do this live broadcast.
0:05:36 > 0:05:39In order to do that we have had to reduce the quality slightly
0:05:39 > 0:05:42from what you can achieve with that camera,
0:05:42 > 0:05:45but we're also recording the raw footage of each of the cameras
0:05:45 > 0:05:47so that at a later date
0:05:47 > 0:05:50we can produce a higher-quality output to use offline.
0:05:50 > 0:05:54Of course, with a lot of money going into this area from broadcasters
0:05:54 > 0:05:55and web streaming companies
0:05:55 > 0:06:00it's not just sporting events that invite our virtual presence.
0:06:00 > 0:06:02The R&D guys have been playing elsewhere.
0:06:02 > 0:06:05- MAN:- In three, two, one. Cue.
0:06:05 > 0:06:08In the BBC newsroom, viewers can see their usual presenter,
0:06:08 > 0:06:11but also the remote controlled cameras
0:06:11 > 0:06:15and glimpse into the director's gallery backstage.
0:06:15 > 0:06:19And out in the field with reporters - literally -
0:06:19 > 0:06:21as part of BBC TWO Springwatch.
0:06:21 > 0:06:24Could this be the future of nature programmes?
0:06:24 > 0:06:28Whether it's broadcasters or other big internet players, ultimately
0:06:28 > 0:06:32these steps are about putting the viewer where the action is
0:06:32 > 0:06:37and allowing them to take a look around just by moving their head.
0:06:37 > 0:06:40If viewers truly invest in its use then these experiments today for
0:06:40 > 0:06:44the Commonwealth Games could be offered up for real
0:06:44 > 0:06:49in time for the next Olympic games in just two years' time.
0:06:49 > 0:06:51Absolutely amazing.
0:06:52 > 0:06:56Dan Simmons experiencing the Games in the round.
0:06:56 > 0:07:00As well as sport, there are virtual reality experiments right now
0:07:00 > 0:07:04which could help us to experience real events that are normally
0:07:04 > 0:07:07only brought to us through newsrooms like this.
0:07:07 > 0:07:10And they can be quite extreme.
0:07:10 > 0:07:13BOY SINGS
0:07:13 > 0:07:15CHATTERING
0:07:15 > 0:07:18The sighs and sounds of Aleppo in Syria
0:07:18 > 0:07:21experienced through a virtual reality headset.
0:07:21 > 0:07:25The participant is transported to a place where anything can happen.
0:07:25 > 0:07:26BOY CONTINUES TO SING
0:07:31 > 0:07:33But this isn't a video game.
0:07:33 > 0:07:36Journalist and filmmaker Nonny De La Pena
0:07:36 > 0:07:40specialises in creating virtual worlds based on real life.
0:07:40 > 0:07:42SHOUTS
0:07:42 > 0:07:44The bomb is from an actual event
0:07:44 > 0:07:47and we had to collect multiple sources to both figure out
0:07:47 > 0:07:50what the buildings looked like before the bomb hit
0:07:50 > 0:07:53and what happened in the aftermath.
0:07:53 > 0:07:58This included mobile phone videos, a video camera
0:07:58 > 0:08:01and various audio that people on scene had gathered.
0:08:01 > 0:08:04Just tell us what you were trying to achieve
0:08:04 > 0:08:06with this really immersive journalism.
0:08:06 > 0:08:10It's really extraordinary how easily the mind can be tricked
0:08:10 > 0:08:14when you use really good virtual reality goggles
0:08:14 > 0:08:17and you use very believable audio
0:08:17 > 0:08:20and fast cameras that track anywhere you look.
0:08:20 > 0:08:22You can really have a sense of presence
0:08:22 > 0:08:24that you're in another place.
0:08:26 > 0:08:29It's also part of something called Project Syria.
0:08:29 > 0:08:32To create it, Nonny deployed a team
0:08:32 > 0:08:35to gather material at a refugee camp on the border.
0:08:37 > 0:08:40That sense of being there, the sense of empathy,
0:08:40 > 0:08:43the sense of deeper understanding of a story, I think,
0:08:43 > 0:08:48really makes these pieces valuable for the future of journalism.
0:08:48 > 0:08:50How do you build it?
0:08:50 > 0:08:52Well, the first one I built,
0:08:52 > 0:08:54which was called Hunger In Los Angeles,
0:08:54 > 0:08:56which we recorded audio at food banks
0:08:56 > 0:08:59and we recorded a day where a man went into a diabetic coma
0:08:59 > 0:09:02because the food line was so long
0:09:02 > 0:09:05and his blood sugar dropped too low before he got sustenance.
0:09:05 > 0:09:09CHATTERING
0:09:09 > 0:09:13That piece I built for 700 of my own money.
0:09:13 > 0:09:16I had to learn a lot of things quickly.
0:09:16 > 0:09:17I begged and borrowed favours.
0:09:17 > 0:09:21Now I tend to get bigger teams,
0:09:21 > 0:09:24we're actually outsourcing some of our model making now.
0:09:24 > 0:09:27How have people reacted who have experienced this?
0:09:27 > 0:09:29It has been really astonishing to me.
0:09:29 > 0:09:33I've had people down on the ground crying. When he falls to the ground,
0:09:33 > 0:09:37I mean, this virtual human, non-existent, I mean, it's a ghost,
0:09:37 > 0:09:38it's nothing there,
0:09:38 > 0:09:41they've literally reached in their pocket for their cellphone
0:09:41 > 0:09:43to call for help before they realise where they are.
0:09:43 > 0:09:45It's like an instantaneous reaction.
0:09:46 > 0:09:48NONNY: What do you think?
0:09:49 > 0:09:51NONNY: Oh, you're crying.
0:09:51 > 0:09:54It may not look like reality just yet, but it's clear that
0:09:54 > 0:09:58the scenes she recreates can still have a very powerful effect
0:09:58 > 0:10:00on those who experience them.
0:10:03 > 0:10:05That was Nonny De Le Pena.
0:10:05 > 0:10:08There's certainly a lot of talk at the moment about VR being able to
0:10:08 > 0:10:11put you in the moment, but, of course,
0:10:11 > 0:10:14there are some moments none of us would rather be in.
0:10:14 > 0:10:17Why not give us your thoughts about the applications of virtual reality
0:10:17 > 0:10:19we've shown you so far.
0:10:19 > 0:10:22E-mail us click@bbc.co.uk or tweet us @bbbclick
0:10:22 > 0:10:26Next up, a look at this week's tech news.
0:10:26 > 0:10:29The UK government has announced that driverless cars
0:10:29 > 0:10:33will be allowed on public roads from January next year.
0:10:33 > 0:10:36Previously, concerns about legal and insurance issues have restricted
0:10:36 > 0:10:40the machines to only being allowed on private roads.
0:10:40 > 0:10:42The government has also invited cities
0:10:42 > 0:10:44to compete in trials of the tech.
0:10:44 > 0:10:47While a review of road regulations has been ordered
0:10:47 > 0:10:49to provide guidelines for their introduction.
0:10:49 > 0:10:53Next step, flying DeLoreans. I promise.
0:10:53 > 0:10:56A highly sophisticated cyber attack on
0:10:56 > 0:11:00Canada's National Research Council could take up to a year to repair
0:11:00 > 0:11:02according to its government.
0:11:02 > 0:11:05The attack which temporarily shut down the research council's
0:11:05 > 0:11:10computers has been blamed on a Chinese state-sponsored actor
0:11:10 > 0:11:12by the Canadian government.
0:11:12 > 0:11:14The Chinese Embassy in Ottawa dismiss
0:11:14 > 0:11:17the report as a groundless allegation.
0:11:17 > 0:11:20It's unclear which information was compromised.
0:11:20 > 0:11:25Games publisher Electronic Arts has announced a new Netflix-like
0:11:25 > 0:11:29subscription service for its games on the Xbox One console.
0:11:29 > 0:11:34Called EA Access, the plan is to ask gamers to stump up £3.99 a month
0:11:34 > 0:11:37for unlimited gaming on a selection of titles,
0:11:37 > 0:11:40providing they keep paying, of course.
0:11:40 > 0:11:43Initially only four games were up for grabs, but the company says
0:11:43 > 0:11:46more will be added before the full launch later this year.
0:11:46 > 0:11:51The service will offer early access and 10% discount to new EA games.
0:11:53 > 0:11:56And finally, it turns out Facebook isn't the only site
0:11:56 > 0:11:58to experiment on its users.
0:11:58 > 0:12:01Lots of them do, including dating company OKCupid.
0:12:01 > 0:12:05The matchmaking site released analytics showing how it made up
0:12:05 > 0:12:09compatibility ratings to influence how people viewed
0:12:09 > 0:12:10prospective matches.
0:12:10 > 0:12:14The result, well, love is just as complicated
0:12:14 > 0:12:17now matter how compatible you're told you are.
0:12:17 > 0:12:18So just like real life.
0:12:23 > 0:12:26Last year we saw this...
0:12:26 > 0:12:30the Android based shield handheld console.
0:12:30 > 0:12:33Well, this week I got the chance to try out graphics chip guru
0:12:33 > 0:12:39Nvidia's latest stab at launching a handheld games machine.
0:12:39 > 0:12:44This time it's an Android tablet called the Shield tablet.
0:12:44 > 0:12:47As tabs go it's got some pretty meaty guts,
0:12:47 > 0:12:50it's probably the most powerful Android tab around,
0:12:50 > 0:12:54boasting a new powerful K1 processor.
0:12:54 > 0:12:58It needs the processing grunt this chip provides
0:12:58 > 0:13:00along with an optional games controller.
0:13:00 > 0:13:03The Shield can play normal Android games
0:13:03 > 0:13:06or it can play a range of older PC games
0:13:06 > 0:13:10which have been optimised for play on the K1 chipset.
0:13:10 > 0:13:14Finally, the Shield can stream and play games from a PC
0:13:14 > 0:13:19as long as that PC is running a high-end Nvidia graphics card.
0:13:20 > 0:13:23One of the questions you may be asking is why
0:13:23 > 0:13:26would I want to take a perfectly good PC gaming experience
0:13:26 > 0:13:29that you can play on a nice big screen like this
0:13:29 > 0:13:31and transfer it to a much smaller screen?
0:13:31 > 0:13:33Especially when these two devices still have to be
0:13:33 > 0:13:36quite close to each other, certainly on the same Wi-Fi network.
0:13:36 > 0:13:38Well, in well, in truth,
0:13:38 > 0:13:42gaming PC are great big towers or they're hulking leviathans
0:13:42 > 0:13:44of a laptop like this one,
0:13:44 > 0:13:47so it might be that you don't want to carry it into the kitchen
0:13:47 > 0:13:48or the bedroom for example.
0:13:48 > 0:13:52So in that case I can understand why you'd want to play this
0:13:52 > 0:13:56on a smaller screen in bed instead.
0:13:56 > 0:14:00As long as you have an understanding other half, of course.
0:14:00 > 0:14:03The tablet can also be plugged into a TV,
0:14:03 > 0:14:07meaning it can play its own Android games on a much bigger screen
0:14:07 > 0:14:09than its own eight inch display.
0:14:12 > 0:14:17Fans of sci-fi movies and TV shows are an incredibly loyal bunch.
0:14:17 > 0:14:19Just ask Sebastian here.
0:14:19 > 0:14:22Which means if you make a video game of their favourite movie
0:14:22 > 0:14:25and you don't get it right, they will not forgive you.
0:14:25 > 0:14:28And that's why the team behind the latest attempt to adapt
0:14:28 > 0:14:33the sci-fi franchise Alien really had its work cut out for it.
0:14:33 > 0:14:37Marc Cieslak has been finding out if anyone can hear him scream.
0:14:39 > 0:14:41- WOMAN:- I don't know if you can hear me.
0:14:41 > 0:14:43An abandoned space station.
0:14:43 > 0:14:45I think...
0:14:45 > 0:14:47I think there's something here.
0:14:47 > 0:14:49Murderous, paranoid androids.
0:14:51 > 0:14:56And the prospect of a close encounter which won't end well.
0:14:59 > 0:15:03Alien Isolation remixes the ingredients from the 1979 movie
0:15:03 > 0:15:07to create a first-person survival horror video game.
0:15:07 > 0:15:11Set 15 years after the events of the sci-fi classic chiller
0:15:11 > 0:15:13the player adopts the role of Amanda Ripley,
0:15:13 > 0:15:16the daughter of the movies' original heroine.
0:15:18 > 0:15:21And in a nod to the big screen incarnation of
0:15:21 > 0:15:23cinema's unfriendliest ET,
0:15:23 > 0:15:26two bonus missions which these exclusive shots reveal
0:15:26 > 0:15:29reimagine key points from the film.
0:15:29 > 0:15:34- MAN:- Whatever it was...it was big and...
0:15:34 > 0:15:37- MAN 2:- You sure it took him under?
0:15:37 > 0:15:39- WOMAN:- Disappeared under one of the cooling ducts.
0:15:39 > 0:15:44And the movie's cast have returned to lend their vocal talents to the game.
0:15:44 > 0:15:46We should never have landed on this.
0:15:46 > 0:15:48Me and Parker, we told them that.
0:15:48 > 0:15:51Brett, over and out.
0:15:52 > 0:15:55Which is why I've come to New York to meet the actress who played
0:15:55 > 0:15:58the only surviving crew member of the commercial shipping vessel
0:15:58 > 0:15:59the Nostromo.
0:15:59 > 0:16:02Sigourney Weaver returns to the role that made her famous,
0:16:02 > 0:16:06this time playing a virtual version of herself in 1979.
0:16:06 > 0:16:09COMPUTER BEEPS
0:16:09 > 0:16:12Why return to the role of Ellen Ripley?
0:16:12 > 0:16:14The movie, you know, is...
0:16:15 > 0:16:18..still, sort of, means something to people.
0:16:18 > 0:16:21I still meet people,
0:16:21 > 0:16:25young people who are still discovering it for the first time.
0:16:25 > 0:16:29And I thought, it's such a specific cool,
0:16:29 > 0:16:32claustrophobic world that the idea of giving everybody
0:16:32 > 0:16:34the opportunity to come into that world
0:16:34 > 0:16:36and make some of those decisions
0:16:36 > 0:16:41and have that adventure, personally, I get it.
0:16:41 > 0:16:46I dig it and I think it's very immersive and really scary
0:16:46 > 0:16:49and also, in its odd way, very beautiful.
0:16:49 > 0:16:53As soon as I open my mouth it was Ripley's voice.
0:16:53 > 0:16:55And I really didn't...
0:16:55 > 0:17:01It was like she'd been sitting next to me for 35 years and...
0:17:01 > 0:17:05I guess if you played a part that many times that they, sort of,
0:17:05 > 0:17:07become part of your DNA.
0:17:07 > 0:17:12So there she was. And we had quite an interesting day.
0:17:12 > 0:17:15Alien is one of cinema's great horror movies.
0:17:15 > 0:17:17Do you think this video game can compete
0:17:17 > 0:17:19in terms of scaring the player?
0:17:20 > 0:17:25You know, in an odd way I think they take the scare
0:17:25 > 0:17:29in a really new visceral direction.
0:17:29 > 0:17:31I notice that when we did Avatar
0:17:31 > 0:17:34that people really hated leaving that world.
0:17:34 > 0:17:37I feel with this that after, probably,
0:17:37 > 0:17:40so many of the fans watching this movie so many times
0:17:40 > 0:17:44that the opportunity to actually trade places
0:17:44 > 0:17:50with one of the characters and be in that world that has haunted you for
0:17:50 > 0:17:54so long will be very satisfying.
0:17:56 > 0:17:59I've only dabbled in video games,
0:17:59 > 0:18:04but I actually think they're a very interesting, creative, new world.
0:18:04 > 0:18:07People who make games are discovering that there's
0:18:07 > 0:18:09a much bigger audience for games.
0:18:09 > 0:18:14It's much more interested in content and in story
0:18:14 > 0:18:19and in subtlety of character and things like that
0:18:19 > 0:18:20than just shoo 'em up.
0:18:22 > 0:18:26I know my husband just directed a video game that's based
0:18:26 > 0:18:28and inspired by a play.
0:18:28 > 0:18:32So I think there's a whole huge world that video games are heading
0:18:32 > 0:18:37into that I think will be fantastic for the audience.
0:18:37 > 0:18:40They'll be the stars of their own picture.
0:18:40 > 0:18:44And gamers will be able to find out if they have the stomach
0:18:44 > 0:18:48to star in their own version of this deep space scare 'em up
0:18:48 > 0:18:50when the title's released in October.
0:18:54 > 0:18:56Back here at Broadcasting House,
0:18:56 > 0:19:00this is Studio A where the A stands for...anything you want it to be.
0:19:00 > 0:19:04Because this is the virtual studio, and all these green walls
0:19:04 > 0:19:09and the green floor can be replaced with any virtual set you fancy.
0:19:09 > 0:19:12The cameras are fitted with these special markers,
0:19:12 > 0:19:16which means the system can track its exact position and then add that
0:19:16 > 0:19:19virtual set at the precise angle it needs to be viewed at.
0:19:19 > 0:19:21And I'll let you into a secret,
0:19:21 > 0:19:24not only does this place double as a news studio...
0:19:24 > 0:19:27..(it's also the Webscape set.)
0:19:27 > 0:19:30Talking of which, here she is - Kate Russell.
0:19:30 > 0:19:33You'd better not make a mess in there, Spencer.
0:19:34 > 0:19:38One of the things I love about virtual space is that
0:19:38 > 0:19:41you can reinvent your own reality any time you like.
0:19:41 > 0:19:44Take public transport, which we all love to complain about
0:19:44 > 0:19:49when it holds us up, but could you do any better than the city planners?
0:19:49 > 0:19:53Transitmix lets you test out your mettle by creating your own
0:19:53 > 0:19:56complex network in whichever city you fancy.
0:19:58 > 0:20:02As you map out your lines and routes, the operating statistics
0:20:02 > 0:20:06and costs of each line will be shown in the control panel.
0:20:06 > 0:20:09Eventually giving you an overall operating budget
0:20:09 > 0:20:11for your transit network.
0:20:11 > 0:20:14You'll have to go to the real city records
0:20:14 > 0:20:17if you want to compare this with reality.
0:20:17 > 0:20:21Some cities, like San Francisco, have existing networks already added,
0:20:21 > 0:20:24so you can choose to edit those routes
0:20:24 > 0:20:27and see if you can make the network run more efficiently.
0:20:27 > 0:20:29Once finished, save and share,
0:20:29 > 0:20:31preferably with your local planning department
0:20:31 > 0:20:35so they can take some wisdom from your work.
0:20:42 > 0:20:46If you have or witness an accident or serious illness
0:20:46 > 0:20:48you call the emergency services.
0:20:48 > 0:20:51But while you're waiting for them to arrive there could be
0:20:51 > 0:20:55a qualified medical first aider close by to offer immediate support.
0:20:55 > 0:21:00If you have the presence of mind to use it, the GoodSAM emergency app
0:21:00 > 0:21:04aims to help people alert any registered first aiders close by
0:21:04 > 0:21:07so they can provide immediate assistance.
0:21:12 > 0:21:16Another potential live saver I found this week is
0:21:16 > 0:21:21courtesy of the British Red Cross and YouTube gaming star Ali-A.
0:21:21 > 0:21:24Lots of games come with epilepsy warnings,
0:21:24 > 0:21:28but according to research by Epilepsy Action almost nine in ten people
0:21:28 > 0:21:32wouldn't know how to help someone who is having a seizure.
0:21:32 > 0:21:34That's the purpose of this video
0:21:34 > 0:21:37that plays out like a first-person shooter game.
0:21:37 > 0:21:38Captain Located. Uh-oh.
0:21:38 > 0:21:42He does not look like he's in a good way right now.
0:21:42 > 0:21:46Let's head over and see how we can assist the captain.
0:21:46 > 0:21:48A few problems here - rigid body,
0:21:48 > 0:21:50arching back, jerking movement.
0:21:55 > 0:21:58Despite a lot of work being done to try and encourage girls
0:21:58 > 0:22:02to think about careers in computing there remains a massive gender gap.
0:22:02 > 0:22:06New initiative Made With Code has put together a brilliant series of
0:22:06 > 0:22:11videos and practical coding projects that aim to appeal to girls across
0:22:11 > 0:22:15the globe by making computer science relative
0:22:15 > 0:22:17to their lives and interests.
0:22:17 > 0:22:21The projects include coding a 3D-printed bracelet,
0:22:21 > 0:22:24making a platform to accessorise your selfies,
0:22:24 > 0:22:30coding a 2D avatar from scratch, creating a unique animated gif
0:22:30 > 0:22:33and putting together your own Beats soundtrack.
0:22:33 > 0:22:36And while the target audience is girls,
0:22:36 > 0:22:40I would think most boys would enjoy coding these projects too,
0:22:40 > 0:22:43and even a couple of parents.
0:22:48 > 0:22:50If you send messages within Facebook
0:22:50 > 0:22:54and don't use the dedicated messenger app on mobile,
0:22:54 > 0:22:57you're about to have your hand forced as the company is
0:22:57 > 0:23:00separating its chat service from the main platform.
0:23:00 > 0:23:04This means you will have to download the free dedicated app
0:23:04 > 0:23:06to keep chatting through Facebook.
0:23:06 > 0:23:08But should experience faster messaging
0:23:08 > 0:23:11untangled from the main timeline.
0:23:19 > 0:23:23Talking of talking, you can now download the first free app for iOS
0:23:23 > 0:23:28that encrypts voice calls - Signal Private Messenger.
0:23:28 > 0:23:32Made by the same open-source security specialists that made
0:23:32 > 0:23:34RedPhone Secure Calls for Android,
0:23:34 > 0:23:38you can make and receive encrypted voice calls cross platform
0:23:38 > 0:23:41with anyone who has either app installed.
0:23:48 > 0:23:50That's Kate Russell's Webscape.
0:23:50 > 0:23:53Your contributions to Webscape always gratefully received.
