0:00:02 > 0:00:04Got a way of hearing gunfire in the most concealed of places?
0:00:04 > 0:00:06I'm all ears.
0:00:20 > 0:00:24This week on Click, we're listening out for the latest tech
0:00:24 > 0:00:27being used in the battle against gun crime.
0:00:27 > 0:00:29Tired of losing your friends at a festival?
0:00:29 > 0:00:33We'll try out the app that could help you to stay in touch.
0:00:33 > 0:00:37There's yet more E3 video games madness.
0:00:37 > 0:00:41And we have the app that aims to keep you dry in Webscape.
0:00:45 > 0:00:49Welcome to Click. I'm Spencer Kelly. And welcome back to Los Angeles.
0:00:49 > 0:00:53Did you know that this is the US's second most populous city,
0:00:53 > 0:00:55the first being New York?
0:00:55 > 0:00:57And, like many large cities,
0:00:57 > 0:00:59LA grapples with two very urban predicaments -
0:00:59 > 0:01:03an understaffed police department and gun violence.
0:01:03 > 0:01:05And, together, they create a lethal problem.
0:01:08 > 0:01:11This isn't the first time that we've covered guns on Click.
0:01:11 > 0:01:15Who can forget the world's first 3D-printed firearm,
0:01:15 > 0:01:18which was made last year by the open source advocate
0:01:18 > 0:01:20and crypto-anarchist, Cody Wilson?
0:01:21 > 0:01:23And, just earlier this month,
0:01:23 > 0:01:25we looked at some of the smart technology
0:01:25 > 0:01:29that was hoping to create a safer type of weapon.
0:01:29 > 0:01:32But, as we reported at the time, even the development of those guns
0:01:32 > 0:01:36has caused a fair amount of controversy here in the US.
0:01:36 > 0:01:39Firearms are a hot topic for debate -
0:01:39 > 0:01:43a debate that occupies the very highest corridors of power.
0:01:43 > 0:01:46It's not even possible to get even the mildest restrictions
0:01:46 > 0:01:50through Congress and that's... We should be ashamed of that.
0:01:50 > 0:01:53Of the thousands of illegal shootings across the country
0:01:53 > 0:01:56each year, the majority are in metropolitan areas,
0:01:56 > 0:02:00where it can be difficult for the police to respond quickly
0:02:00 > 0:02:03and accurately to the sound of gunfire.
0:02:03 > 0:02:05Especially because, again, like most cities,
0:02:05 > 0:02:08there are plenty of places just off the beaten track
0:02:08 > 0:02:10which are out of sight of the cops.
0:02:10 > 0:02:13But LA has a bit of help on its side.
0:02:13 > 0:02:16Something called gunshot detection technology.
0:02:16 > 0:02:19Sumi Das has been looking at the sensors serving
0:02:19 > 0:02:22as law enforcement's ears on the streets.
0:02:23 > 0:02:24RAPID GUNFIRE
0:02:24 > 0:02:26Shots ring out.
0:02:26 > 0:02:30They're heard at this Northern California surveillance centre,
0:02:30 > 0:02:34but were actually fired thousands of miles away, in Puerto Rico.
0:02:34 > 0:02:38We pioneered the concept of using collaborative sensors
0:02:38 > 0:02:41to be able listen to and detect impulsive noises, gunshots,
0:02:41 > 0:02:45and be able to triangulate on the exact location
0:02:45 > 0:02:47from where those gunshots have happened.
0:02:47 > 0:02:52It's called ShotSpotter and it was developed by SST.
0:02:52 > 0:02:56When a gun is fired outdoors in one of the 80 places
0:02:56 > 0:03:00where ShotSpotter sensors are installed, an alert is triggered.
0:03:00 > 0:03:03I guess I'm wondering how many times it might make a mistake,
0:03:03 > 0:03:06how often the technology might mistake fireworks
0:03:06 > 0:03:09or a car that's backfiring for a gunshot.
0:03:09 > 0:03:12The computer's actually about 80% accurate.
0:03:12 > 0:03:14And, er...
0:03:14 > 0:03:17that's why we put the human into the loop.
0:03:17 > 0:03:21Acoustic experts at SST's Incident Review Centre
0:03:21 > 0:03:25verify that the noises are indeed gunshots.
0:03:25 > 0:03:28They further pinpoint the shooter's location,
0:03:28 > 0:03:31then send that information to local authorities,
0:03:31 > 0:03:34all in less than a minute.
0:03:34 > 0:03:36If we can get police out there quicker,
0:03:36 > 0:03:39perhaps when the perpetrators are still there,
0:03:39 > 0:03:44or collect evidence quicker, get to victims quicker,
0:03:44 > 0:03:48that will have long-term benefits for the overall crime rate.
0:03:48 > 0:03:52The sensors, which SST couldn't show us for security reasons,
0:03:52 > 0:03:57are mounted high on rooftops or utility poles to prevent tampering.
0:03:57 > 0:04:02They use GPS to establish the exact time of gunfire.
0:04:02 > 0:04:06That sound will arrive at each sensor at a different time.
0:04:06 > 0:04:10We use that time difference to start drawing hyperbolas.
0:04:10 > 0:04:12Where the hyperbolas intersect
0:04:12 > 0:04:14is the solution of where our shooter is.
0:04:14 > 0:04:15For law enforcement,
0:04:15 > 0:04:18ShotSpotter offers an extra ear to the ground,
0:04:18 > 0:04:22but that advantage is lost when a shooter enters a building,
0:04:22 > 0:04:29so SST is piloting an indoor gunshot detection system, called SiteSecure,
0:04:29 > 0:04:33to be used in places like airports and schools.
0:04:33 > 0:04:38And because this is automated, they can initiate protocols.
0:04:38 > 0:04:41For instance, if this were a school,
0:04:41 > 0:04:45they could initiate a lockdown process.
0:04:45 > 0:04:48But real-time information carries a cost.
0:04:48 > 0:04:51Oakland, California, struggles with street violence,
0:04:51 > 0:04:55yet it's considering scrapping its outdoor ShotSpotter system,
0:04:55 > 0:04:58which runs 260,000 a year.
0:05:00 > 0:05:05Privacy advocates are critical of ShotSpotter's constant monitoring.
0:05:05 > 0:05:08We know that ShotSpotter can pick up conversations,
0:05:08 > 0:05:13but I would like to know more about the capabilities of the equipment.
0:05:13 > 0:05:16How exactly are the microphones activated?
0:05:16 > 0:05:19Where is the data going? Who is reviewing it?
0:05:19 > 0:05:22Still, some cities, like San Francisco,
0:05:22 > 0:05:25are expanding ShotSpotter coverage.
0:05:25 > 0:05:30Without ShotSpotter, we're dependent upon someone to call 911.
0:05:30 > 0:05:33We would be responding to where that person called from,
0:05:33 > 0:05:36not necessarily where the shots actually came from.
0:05:36 > 0:05:39ShotSpotter data is also admissible in court
0:05:39 > 0:05:43and has been used to obtain convictions.
0:05:43 > 0:05:46Even with these benefits, though, the question remains -
0:05:46 > 0:05:48can ShotSpotter make a difference,
0:05:48 > 0:05:52as authorities take aim at the growing problem of gun violence?
0:05:56 > 0:06:00Sumi Das with a fascinating way of keeping that place
0:06:00 > 0:06:02just that little bit safer.
0:06:02 > 0:06:05OK, there's more from Click in California in a couple of minutes,
0:06:05 > 0:06:08after this week's Tech News.
0:06:08 > 0:06:11The internet trade in images that show child sex abuse
0:06:11 > 0:06:13is now an epidemic, according to
0:06:13 > 0:06:16the head of the global initiative to combat the problem.
0:06:16 > 0:06:18Police officers from around the world
0:06:18 > 0:06:20serve on the Virtual Global Taskforce
0:06:20 > 0:06:22and its chairman, Ian Quinn,
0:06:22 > 0:06:25told the BBC there's been an explosion in cases
0:06:25 > 0:06:27handled by US authorities,
0:06:27 > 0:06:30with a raid by officers in Los Angeles alone
0:06:30 > 0:06:32happening on average every other day.
0:06:32 > 0:06:35Specialised internet tracking technology is now being
0:06:35 > 0:06:39used by American officers to pinpoint those accessing
0:06:39 > 0:06:42some child pornography sites in real-time.
0:06:42 > 0:06:45Amazon is to go into the smartphone business next month
0:06:45 > 0:06:47after revealing the Fire Phone.
0:06:47 > 0:06:50The device promises to offer 3D visuals,
0:06:50 > 0:06:53thanks to a number of face-tracking cameras on its front.
0:06:53 > 0:06:56It's also pre-loaded with an app called Firefly,
0:06:56 > 0:06:59which allows the phone to recognise text, images,
0:06:59 > 0:07:01sounds and objects around it.
0:07:01 > 0:07:05Amazon hopes the app will make it easier to buy said items from...
0:07:05 > 0:07:08Yep, you guessed it - the Amazon store.
0:07:08 > 0:07:12The phone has a similar price to the iPhone 5S and the Galaxy S5
0:07:12 > 0:07:17and will go on sale in the US on the 25th of July.
0:07:17 > 0:07:19The UK Government has revealed
0:07:19 > 0:07:23why it's legally able to spy on British citizens
0:07:23 > 0:07:27and their use of companies like Google, Facebook and Twitter.
0:07:27 > 0:07:31The head of the UK intelligence service, GCHQ, said the firms,
0:07:31 > 0:07:32as well as web-based e-mail,
0:07:32 > 0:07:35were classified as external communications
0:07:35 > 0:07:36because they're based abroad
0:07:36 > 0:07:39and therefore didn't require specific warrants.
0:07:39 > 0:07:42The policy, which has long been suspected,
0:07:42 > 0:07:44was revealed as part of a legal battle
0:07:44 > 0:07:47with campaign group Privacy International.
0:07:47 > 0:07:50And, finally, what do you think your video games collection
0:07:50 > 0:07:52might be worth?
0:07:52 > 0:07:57Michael Thomasson has just sold his for 750,000,
0:07:57 > 0:08:00but then he did have the world's largest.
0:08:00 > 0:08:02The collection, 20 years in the making,
0:08:02 > 0:08:06contains over 11,000 titles for 22 consoles.
0:08:06 > 0:08:09Well, at least he's got a bit of space around the house now.
0:08:15 > 0:08:17Now, if you're into the World Cup,
0:08:17 > 0:08:21and apparently it IS possible to like football AND tech,
0:08:21 > 0:08:24here's something that could broaden your perspective
0:08:24 > 0:08:28on just how bonkers host nation Brazil goes over the tournament.
0:08:30 > 0:08:33Every four years, Brazilian communities get together
0:08:33 > 0:08:35and paint the town red...
0:08:35 > 0:08:37green, yellow and blue.
0:08:37 > 0:08:40In fact, entire streets get a make-over and, this year,
0:08:40 > 0:08:44you can explore those designs using Google Street View.
0:08:45 > 0:08:48This tradition in Brazil goes back 30 years ago,
0:08:48 > 0:08:52when communities got together and they decorated,
0:08:52 > 0:08:55they painted the streets with Brazil flag colours.
0:08:55 > 0:08:59Do it for the games. This is street art made by soccer fans.
0:08:59 > 0:09:02So it has a lot of passion, it's a lot of fun,
0:09:02 > 0:09:04it's a community get-together.
0:09:04 > 0:09:08See? It almost makes you feel like you're there.
0:09:08 > 0:09:10All I need now is some vague understanding
0:09:10 > 0:09:13of the rules of football.
0:09:13 > 0:09:15If you've ever been to a massive event
0:09:15 > 0:09:18and you've tried to call your mates somewhere else within the grounds,
0:09:18 > 0:09:22you'll know that getting a signal can sometimes be nearly impossible,
0:09:22 > 0:09:24due to all the phones overloading the system.
0:09:24 > 0:09:26Well, perhaps no longer.
0:09:26 > 0:09:30Apple recently introduced a networking technology
0:09:30 > 0:09:35which some are saying could herald the second mobile revolution.
0:09:35 > 0:09:36Here's Richard Taylor.
0:09:38 > 0:09:42Festivals - a time to let loose and make new connections.
0:09:42 > 0:09:46This tech-savvy crowd is at the cutting edge of communications
0:09:46 > 0:09:49and yet, ironically, the term "contactless"
0:09:49 > 0:09:51here refers more than cash payments.
0:09:51 > 0:09:55Simply sending a text message to a friend across the park
0:09:55 > 0:09:56can by nigh-on impossible,
0:09:56 > 0:10:01as mobile cell towers get overloaded by the weight of partygoers.
0:10:01 > 0:10:04Now, though, the sheer volume of people using smartphones
0:10:04 > 0:10:07can itself bridge the problem it created.
0:10:07 > 0:10:10Each handset would become a point in a mesh network,
0:10:10 > 0:10:14a technology recently enabled in Apple's iOS7,
0:10:14 > 0:10:18opening the door to an entirely new class of apps.
0:10:18 > 0:10:23This is FireChat, a totally free Android and iOS messaging app
0:10:23 > 0:10:25with a twist.
0:10:25 > 0:10:27With FireChat, you can actually use it
0:10:27 > 0:10:30when you're in places where normally you don't have internet access,
0:10:30 > 0:10:34so it can be on the train, on an airplane,
0:10:34 > 0:10:36at the stadium, for example.
0:10:36 > 0:10:39Or indeed, anywhere else in what would otherwise be
0:10:39 > 0:10:42a communications black hole.
0:10:42 > 0:10:45We're getting more than two new users per second,
0:10:45 > 0:10:48we have seen peaks of several hundred thousands
0:10:48 > 0:10:49of installs per day.
0:10:49 > 0:10:51So, how does FireChat work?
0:10:51 > 0:10:54Well, in the absence of a connection to the outside world,
0:10:54 > 0:10:57it takes advantage of two other technologies
0:10:57 > 0:11:00commonly found in today's smartphones - Wi-Fi and Bluetooth.
0:11:00 > 0:11:03Once they're on, you can send a message to anywhere within range
0:11:03 > 0:11:07of about 100ft, so for example, to that shady-looking character there.
0:11:07 > 0:11:11Now, I might, of course, be the intended recipient of the message,
0:11:11 > 0:11:13but it doesn't matter if I'm not,
0:11:13 > 0:11:17cos FireChat effectively turns my handset into a router,
0:11:17 > 0:11:20allowing the message to be passed on through any number of users
0:11:20 > 0:11:22further down the chain.
0:11:22 > 0:11:27Eventually, it reaches me, at the end of this so-called mesh network.
0:11:27 > 0:11:30No mobile phone signal or internet connection needed.
0:11:30 > 0:11:33But if I do happen to have an internet connection,
0:11:33 > 0:11:36well, through the magic of mesh, I can share it
0:11:36 > 0:11:37with everyone else in the chain.
0:11:39 > 0:11:42But it does mean FireChat needs a critical mass of users
0:11:42 > 0:11:45if it's to be of any real use.
0:11:45 > 0:11:48It's all-or-nothing, isn't it, for FireChat?
0:11:48 > 0:11:49So we need massive scale
0:11:49 > 0:11:52and we are on a good trend to meet massive scale
0:11:52 > 0:11:55and we also made a lot of studies to figure out which would be
0:11:55 > 0:11:58the minimum in urban areas, how many people we would need to reach.
0:11:58 > 0:12:00And, in theory,
0:12:00 > 0:12:04we need 7-8% penetration ratio in urban area
0:12:04 > 0:12:06to enable you to be connected to someone else
0:12:06 > 0:12:08more than 93% of the time.
0:12:08 > 0:12:09Let me show you how it works.
0:12:09 > 0:12:13Mesh networking itself, even on smartphones, isn't entirely new.
0:12:13 > 0:12:16An Australian researcher has been working on a solution
0:12:16 > 0:12:20for a few years, stressing its use in remote areas or disaster zones,
0:12:20 > 0:12:22where connectivity has been severed,
0:12:22 > 0:12:25but the tech can be put to other ends, too -
0:12:25 > 0:12:28used, for example, by groups wanting to keep their communications
0:12:28 > 0:12:32completely concealed from the prying eyes of the authorities.
0:12:34 > 0:12:37FireChat say right now their app is aimed less at radicals
0:12:37 > 0:12:41and more at revellers who'd find this decentralised network
0:12:41 > 0:12:44more useful than the traditional social networks in evidence.
0:12:44 > 0:12:48But if or when it becomes truly mainstream,
0:12:48 > 0:12:51that's when both its full potential and pitfalls will emerge.
0:12:55 > 0:12:58It's certainly an intriguing idea. The FireChat founder
0:12:58 > 0:13:02telling Richard Taylor in all his various personae - and outfits -
0:13:02 > 0:13:05why he thinks off-the-grid communications could be a winner
0:13:05 > 0:13:08and when messages become encrypted -
0:13:08 > 0:13:11that's when I think we'll be hearing just a bit more about this.
0:13:14 > 0:13:16Last week,
0:13:16 > 0:13:19we brought you the big announcements from the E3 video games show
0:13:19 > 0:13:22that was held here in LA and we looked in detail
0:13:22 > 0:13:23at the virtual reality headsets
0:13:23 > 0:13:26which are threatening to swallow your face
0:13:26 > 0:13:28and project you into a fantasy world.
0:13:28 > 0:13:31This week, we're going to take a closer look at the big new games
0:13:31 > 0:13:34that were announced at the show, now we've finally found
0:13:34 > 0:13:38Mark Cieslak again and confiscated his games console.
0:13:39 > 0:13:42New games. Loads of them.
0:13:42 > 0:13:46For new consoles, of which there aren't loads, just two.
0:13:46 > 0:13:48The success of this console generation
0:13:48 > 0:13:51rests on the simulated shoulders of the games on show
0:13:51 > 0:13:55inside the cavernous halls of the LA Convention Centre.
0:13:55 > 0:13:59So, two relatively new consoles - the Xbox One and PS4 -
0:13:59 > 0:14:01with a lot to prove.
0:14:01 > 0:14:05It's fortunate then that this year's E3 is a vintage one,
0:14:05 > 0:14:08in terms of games which have the potential
0:14:08 > 0:14:11to exploit the promised power of the next generation.
0:14:13 > 0:14:15Here's the situation.
0:14:15 > 0:14:18A contaminated energy drink has turned everyone into mutants.
0:14:18 > 0:14:20The Day-Glo comic strip stylings
0:14:20 > 0:14:24and free-running inspired gameplay of third-person shooter Sunset Overdrive
0:14:24 > 0:14:29are the tip of the unusual iceberg that is Xbox One exclusive.
0:14:29 > 0:14:32The player must make use of increasingly weird weapons,
0:14:32 > 0:14:36chaining moves to perform ever-more devastating attacks.
0:14:39 > 0:14:44There's more third-person combat on offer in Tom Clancy's The Division.
0:14:44 > 0:14:48Special forces types operate in a post-plague-ridden New York City.
0:14:48 > 0:14:51Smart tactics and stealth are rewarded over shoot first,
0:14:51 > 0:14:54ask - "Doesn't this environment feel a bit inspired by I Am Legend?" -
0:14:54 > 0:14:55questions later.
0:14:55 > 0:14:57Dude, check out Manhattan.
0:14:57 > 0:14:59All of this delivered
0:14:59 > 0:15:01to a go-anywhere, persistent online open world.
0:15:04 > 0:15:07Not every game on show involved guns and ammo, though.
0:15:07 > 0:15:09Sony showcased the mesmerising
0:15:09 > 0:15:13and seemingly serene underwater adventure Abzu.
0:15:16 > 0:15:17As well as Entwined,
0:15:17 > 0:15:20a colourful slice of Playstation-exclusive psychedelia,
0:15:20 > 0:15:24designed by a team of students from the Carnegie Mellon University,
0:15:24 > 0:15:27who were later recruited by Sony.
0:15:27 > 0:15:30A multiplayer title with elements of a rhythm game,
0:15:30 > 0:15:32involving uniting a bird and a fish,
0:15:32 > 0:15:35as they fly through a variety of shapes and patterns.
0:15:35 > 0:15:38That'll be normal, then(!)
0:15:41 > 0:15:44With virtual reality headsets in the works from Sony and Oculus Rift,
0:15:44 > 0:15:48games developers seem keen to get to grips with the technology.
0:15:48 > 0:15:50The Assembly is a VR puzzler,
0:15:50 > 0:15:53set in a mysterious underground testing facility.
0:15:53 > 0:15:55The player must use the objects they find around them
0:15:55 > 0:15:58to escape further tortuous testing.
0:15:58 > 0:16:01Yes! The door's opened!
0:16:01 > 0:16:06It isn't all brand-new fresh ideas on show, though. Perish the thought.
0:16:06 > 0:16:10Franchise, fan favourites - or flogged horses if you prefer -
0:16:10 > 0:16:13are in plentiful supply here at E3 2014.
0:16:15 > 0:16:18Shoot things up a mountain in Ubisoft's Far Cry 4.
0:16:19 > 0:16:23Shoot more things in Electronic Arts' new Battlefield Hardline,
0:16:23 > 0:16:27in which the series receives a cops and robbers multiplayer make-over,
0:16:27 > 0:16:31with online teams adopting the role of lawbreaker or law enforcer.
0:16:32 > 0:16:34You have the right to remain silent!
0:16:36 > 0:16:38The biggest shooting-things franchise of them all
0:16:38 > 0:16:42is, of course, Activision's Call Of Duty, or CoD to its friends.
0:16:42 > 0:16:44Set in the near future,
0:16:44 > 0:16:47this year's instalment is called Advanced Warfare.
0:16:47 > 0:16:50It's had a futuristic face-lift, now featuring exosuits,
0:16:50 > 0:16:54which allow the player to jump tall buildings in a single bound,
0:16:54 > 0:16:57as well as a villainous turn from Kevin Spacey.
0:16:57 > 0:16:59And that's where I come in.
0:16:59 > 0:17:03Its sci-fi stylings are clearly an attempt to keep the series fresh,
0:17:03 > 0:17:06but can CoD maintain its successful streak?
0:17:06 > 0:17:09I think we got a lot of the same questions
0:17:09 > 0:17:12when the franchise moved from World War II to modern.
0:17:12 > 0:17:15People thought of it at that time as a World War II franchise.
0:17:15 > 0:17:19And then the shift to modern opened up all kinds of new possibilities,
0:17:19 > 0:17:22new interactions, new weapons, new capabilities,
0:17:22 > 0:17:25and the move to the near future has done the same thing.
0:17:25 > 0:17:29So lots of familiar franchises filling the show floors,
0:17:29 > 0:17:32but E3 2014 still offered plenty of new
0:17:32 > 0:17:35and, in some cases, different gaming experiences.
0:17:38 > 0:17:42Ask anyone why they live in LA and they're bound to say the weather.
0:17:42 > 0:17:44Turned out nice again.
0:17:44 > 0:17:46But I'm soon going to be heading back to a very British summer
0:17:46 > 0:17:50where anything can happen, as long as it starts with rain.
0:17:50 > 0:17:53Well, Kate Russell's found an app which is the perfect accompaniment,
0:17:53 > 0:17:56because it warns you when there's a shower on the way.
0:17:56 > 0:17:57Here comes Webscape.
0:18:03 > 0:18:05With the picnic season in full swing,
0:18:05 > 0:18:10the one thing that is bound to spoil a day out is an unexpected downpour,
0:18:10 > 0:18:13drenching you and your cheese and pickle sandwiches.
0:18:13 > 0:18:16Rain Alarm is a browser-based tool that will warn you
0:18:16 > 0:18:20if there's bad weather heading your way, like rain or snow.
0:18:21 > 0:18:24# Why does it always rain on me? #
0:18:24 > 0:18:27The data comes from government weather services
0:18:27 > 0:18:29and is updated every 30 minutes.
0:18:29 > 0:18:32You'll need to check under the help button
0:18:32 > 0:18:35to see if the country you want to check out is covered
0:18:35 > 0:18:40but, if it is, you should never get caught in a sudden downpour again.
0:18:40 > 0:18:43You can also run it through a Chrome or Firefox browser extension
0:18:43 > 0:18:47and there are apps for Android, iPhone and Windows Phone
0:18:47 > 0:18:50that will ping you an alert when rain is headed your way.
0:18:55 > 0:18:58# When I met you in the summer... #
0:18:58 > 0:19:02One place we hope there won't be any rain is Wimbledon.
0:19:02 > 0:19:04If you can't make it there yourself,
0:19:04 > 0:19:09join 20 million other fans on the revamped website and smartphone apps,
0:19:09 > 0:19:14with live video to many regions, lots of analysis, predictions and
0:19:14 > 0:19:18social tools to bring the whole world together, cheering on the athletes.
0:19:21 > 0:19:25# When I met you in the summer... #
0:19:25 > 0:19:27The waiting is over!
0:19:30 > 0:19:32# When on foreign shores... #
0:19:32 > 0:19:36History buffs will love the gorgeous interactive content
0:19:36 > 0:19:42in Roman Ruins HD, which is only available on iPad for £6.99.
0:19:42 > 0:19:46It lets you wander around some the most awe-inspiring historic sites
0:19:46 > 0:19:49from the Roman Empire without leaving your front room.
0:19:49 > 0:19:55# Baby, when in Rome, I do as the Romans do. #
0:19:56 > 0:19:59This app might seem quite expensive,
0:19:59 > 0:20:05but when you start exploring the 1,500-plus high-definition photos
0:20:05 > 0:20:09with expert narration, 3D aerial views,
0:20:09 > 0:20:13and oodles more fantastic content, it's not hard to see why the
0:20:13 > 0:20:18tablet computer is becoming the new coffee table tome in so many homes.
0:20:21 > 0:20:25Another fine example in this genre is Interaction Of Colour,
0:20:25 > 0:20:27also for the iPad.
0:20:27 > 0:20:31This is the digital interpretation of Josef Albers'
0:20:31 > 0:20:34famous masterwork of colour experimentation,
0:20:34 > 0:20:39which is seen by many as an essential handbook for artists and educators.
0:20:39 > 0:20:42There is a free sampler of chapter ten.
0:20:42 > 0:20:44If you like what you see, you can
0:20:44 > 0:20:48upgrade to the full version through an in-app purchase of £10.
0:20:50 > 0:20:55# It's such a shame our friendship had to end... #
0:20:55 > 0:20:58Kate Russell's Webscape and, if you missed those links,
0:20:58 > 0:21:02they are available, of course, at our website.
0:21:02 > 0:21:05If you'd like to suggest an app or a site for Webscape,
0:21:05 > 0:21:08you're more than welcome. We are at...
0:21:14 > 0:21:18Just before we go, we thought we might enjoy this.
0:21:18 > 0:21:21Now, if you're into your running, skateboarding or motocross,
0:21:21 > 0:21:24I'm sure you've fancied videoing yourself as you break
0:21:24 > 0:21:29the sound barrier, defy gravity or, in my case, just stay upright.
0:21:29 > 0:21:32Well, a drone would be the ideal thing to use.
0:21:32 > 0:21:37And certainly, drone selfies, or dronies, are becoming more popular.
0:21:37 > 0:21:39Except for the fact that piloting one
0:21:39 > 0:21:43whilst you yourself are airborne isn't really that possible.
0:21:43 > 0:21:47Well, look out because here comes Hexoplus,
0:21:47 > 0:21:50the drone that flies itself.
0:21:50 > 0:21:54Just choose the subject and Hexoplus will keep them in shot
0:21:54 > 0:21:56and follow them as they move,
0:21:56 > 0:22:01sometimes flying at speeds of up to 70kph to keep up with them.
0:22:01 > 0:22:05Although at the moment, it does only have 15 minutes of battery life,
0:22:05 > 0:22:09so I obviously couldn't take on my morning marathon around LA.
0:22:09 > 0:22:13Anyway, the project is currently in Kickstarter mode
0:22:13 > 0:22:17and it's already raised over six times its 50,000 goal
0:22:17 > 0:22:19and, if it does live up to its promise,
0:22:19 > 0:22:24we could certainly see some very high-action dronies in the future.
0:22:24 > 0:22:28I'm afraid that really is it, though, from California.
0:22:28 > 0:22:32Thank you for watching and we'll see you next time.
