0:00:05 > 0:00:08This week: 3-D printed legs.
0:00:08 > 0:00:13Careless cash machines.
0:00:13 > 0:00:14And aliens.
0:00:14 > 0:00:18Lots and lots of aliens.
0:00:39 > 0:00:42I've always wanted to go into space.
0:00:42 > 0:00:45Hey, I'm a future boy, always have been.
0:00:45 > 0:00:49And I'm lucky to be living in a time when the beauty of the universe
0:00:49 > 0:00:51is being brought to life.
0:00:51 > 0:00:54From earth you can now photograph amazing skies, if you know
0:00:54 > 0:00:57what you are doing.
0:00:57 > 0:00:59Which the entrants for this years Insight Astronomy Photographer
0:00:59 > 0:01:04of the Year Awards clearly do.
0:01:10 > 0:01:14Actually going into space though is still a pipe dream for me.
0:01:14 > 0:01:18Unless you count shoddy TV effects like this.
0:01:18 > 0:01:19Oh, and videogames of course.
0:01:19 > 0:01:23If you count video games I have already been across the galaxy.
0:01:23 > 0:01:27There are a number of games around now you see which let you go
0:01:27 > 0:01:29absolutely anywhere.
0:01:29 > 0:01:32The question is, would you want to?
0:01:32 > 0:01:35Marc Cieslak has been to meet the makers of what is quite possibly
0:01:35 > 0:01:39the most universal game yet.
0:01:45 > 0:01:49I grew up reading sci-fi books, looking at the covers,
0:01:49 > 0:01:56when I close my eyes and think of science-fiction I think of that.
0:01:56 > 0:02:00I think of a lone astronaut stood on a desolate planet with a couple
0:02:00 > 0:02:04of other huge planets hanging in the horizon and these kind
0:02:04 > 0:02:07of wild and crazy worlds.
0:02:07 > 0:02:12No Man's Sky is a space exploration game.
0:02:12 > 0:02:17It encourages the player to discover strange new worlds and lifeforms.
0:02:17 > 0:02:19There is trading and commerce.
0:02:19 > 0:02:24As well as allowing people to blow stuff up.
0:02:24 > 0:02:27All in a playable universe which is so big the games
0:02:27 > 0:02:31own designers predict most players won't even experience one percent
0:02:31 > 0:02:38of the worlds the game has to offer.
0:02:40 > 0:02:44It might be a game with a gigantic exotic alien universe to explore
0:02:44 > 0:02:47but it has been created in these tiny offices beneath a taxi
0:02:47 > 0:02:54company in Guildford.
0:02:54 > 0:02:59Indie games company Hello Games consists of just 11 people.
0:02:59 > 0:03:09The team's previous credits include fun stunt riding game Joe Danger.
0:03:09 > 0:03:13No Man's Sky is the brainchild of Sean Murray, who,
0:03:13 > 0:03:16along with this tiny team, has found a clever way to fashion
0:03:16 > 0:03:22this gigantic game and it's all thanks to maths.
0:03:22 > 0:03:25We are trying to build an entire universe and we can't build that
0:03:25 > 0:03:30by hand, normally when you make a game it's a series of levels
0:03:30 > 0:03:35and some artist or designer has built every one of those
0:03:35 > 0:03:37levels piece by piece, arranged all the furniture
0:03:37 > 0:03:42and everything like that.
0:03:42 > 0:03:45But we want to build something of a huge, huge scale.
0:03:45 > 0:03:48We just can't do that on our own, we're this tiny indie team,
0:03:48 > 0:03:51so what we do is we use the computer to build it.
0:03:51 > 0:03:55We create a bunch of rules, a set of maths and the computer runs that,
0:03:55 > 0:03:58we effectively teach the computer the rules that we think we need
0:03:58 > 0:04:00to build a universe.
0:04:00 > 0:04:04The computer goes off and generates it, builds it for you.
0:04:04 > 0:04:07This process is called procedural generation and it is how everything
0:04:07 > 0:04:10in the game is made.
0:04:10 > 0:04:13From the planets to the aliens to the ships to the smallest
0:04:13 > 0:04:16blade of grass.
0:04:16 > 0:04:18It's not random, those rules are there for a reason.
0:04:18 > 0:04:22What we are trying to do is create a set of rules and formula
0:04:22 > 0:04:28that we feel creates a nice looking universe.
0:04:28 > 0:04:32The size of the universe is incredibly big.
0:04:32 > 0:04:36There are a lot of planets, if you were to visit them
0:04:36 > 0:04:39all there would be 18 Quintilian which is this huge number,
0:04:39 > 0:04:45it's like 2 to the power of 64.
0:04:45 > 0:04:46It's a hard number to comprehend.
0:04:46 > 0:04:49The way I normally say it is like if you were to discover
0:04:49 > 0:04:53a planet or a planet was to be discovered in No Man's Sky every
0:04:53 > 0:04:55second it would take about 500 billion years for them
0:04:55 > 0:05:03all to be discovered.
0:05:03 > 0:05:06With its first reveal back at E3 in 2014 this game generated
0:05:06 > 0:05:08a considerable amount of anticipation as well as
0:05:08 > 0:05:09hype amongst gamers.
0:05:09 > 0:05:13I'm feeling a lot of emotions right now.
0:05:13 > 0:05:16However some of this attention hasn't all been positive.
0:05:16 > 0:05:19One gamer claims to have purchased a copy of the game ahead
0:05:19 > 0:05:24of release for ?1200 via eBay.
0:05:24 > 0:05:26After posting clips online he claimed it's possible to reach
0:05:26 > 0:05:29the centre of the game's universe in just 30 hours.
0:05:29 > 0:05:33This is a task developers have suggested would actually take
0:05:33 > 0:05:38about 100 hours of playtime.
0:05:38 > 0:05:42Sean Murray has implored fans to avoid these online spoilers.
0:05:42 > 0:05:46There is a big update coming on the first day of the game's
0:05:46 > 0:05:53release but I got a chance to play No Man's Sky for a couple of hours.
0:05:53 > 0:05:57Okay, I have woken up on a planet with a damaged spacecraft,
0:05:57 > 0:06:02I had to repair that ship by finding various minerals or mining minerals
0:06:02 > 0:06:05and finding the parts and making the parts required to take
0:06:05 > 0:06:11the ship off.
0:06:11 > 0:06:15It's the introduction to a lot of the game's exploration mechanic.
0:06:15 > 0:06:20So I have already met some unusual alien species.
0:06:20 > 0:06:22And all of the aliens in the game are generated,
0:06:22 > 0:06:29as everything else is, procedurally.
0:06:29 > 0:06:32So this is where the game starts in earnest.
0:06:32 > 0:06:35Explore an entire universe.
0:06:35 > 0:06:36I do want to go?
0:06:36 > 0:06:41Well, second star on the right and straight on till morning.
0:06:41 > 0:06:44There is a risk that people might find it boring,
0:06:44 > 0:06:48I think it will appeal to a certain type of gamer that likes the grind,
0:06:48 > 0:06:51the repetitive actions of going around and mining
0:06:51 > 0:06:54and getting resources in order to travel around.
0:06:54 > 0:06:57But I think once you've got past that initial
0:06:57 > 0:07:00maybe a couple of hours, you are going to find there
0:07:00 > 0:07:04is a massive universe to explore.
0:07:04 > 0:07:07When it is released next week fans will be able to decide
0:07:07 > 0:07:13for themselves if the wait for No Man's Sky has been worth it.
0:07:18 > 0:07:19It certainly looks really nice doesn't it?
0:07:19 > 0:07:22Yeah it is really pretty, when I was chatting to the game's
0:07:22 > 0:07:25lead designer, Sean Murray, he said there was a definite
0:07:25 > 0:07:27aesthetic they wanted to give the game.
0:07:27 > 0:07:32A lot of contemporary sci-fi games look really sort of gritty and dirty
0:07:32 > 0:07:35and he wanted this to be quite optimistic and bright and sunny.
0:07:35 > 0:07:38It does, to my mind it looks a bit like a 70s
0:07:38 > 0:07:39prog rock album cover.
0:07:39 > 0:07:42It does, is it any good?
0:07:42 > 0:07:44That is a difficult thing to say because I have
0:07:44 > 0:07:45played it for a few hours.
0:07:45 > 0:07:49It's so big, there is so much in there that you cannot really make
0:07:49 > 0:07:54that judgement unless you have committed lots, lots more hours.
0:07:54 > 0:07:56That's the thing, it's so big because the computers are designing
0:07:56 > 0:07:58everything, the planets and lifeforms, it's not
0:07:58 > 0:08:02as if some human has had to go and design everything meticulously.
0:08:02 > 0:08:06The beef I have with these procedural games,
0:08:06 > 0:08:09like Elite Dangerous which you know I play, is that although you can go
0:08:09 > 0:08:11anywhere and technically see anything the computers cannot
0:08:11 > 0:08:13generate storylines which are compelling so you find
0:08:13 > 0:08:17there is not actually much to do.
0:08:17 > 0:08:19It's quite an unforgiving universe, an unforgiving galaxy in these
0:08:19 > 0:08:22games, the player is just dumped into the game and told go ahead
0:08:22 > 0:08:25and make your own fun.
0:08:25 > 0:08:28It's a bit like going on holiday with your mum and dad
0:08:28 > 0:08:31when you are nine, you go to the beach and they are like,
0:08:31 > 0:08:32make your own fun.
0:08:32 > 0:08:34This is very similar to that.
0:08:34 > 0:08:36If people are expecting a single player game
0:08:36 > 0:08:39where they are led by the hand this is not that kind of experience,
0:08:40 > 0:08:44this is find stuff for yourself.
0:08:44 > 0:08:46OK Marc, see you in the sky.
0:08:50 > 0:08:53Medical treatment can be costly even in the rich parts of the world
0:08:53 > 0:08:56but in the developing parts of the world it can be prohibitive
0:08:56 > 0:08:59but there is a Silicon Valley start-up called D-Rev
0:08:59 > 0:09:01that is trying to address this healthcare gap
0:09:01 > 0:09:03by developing affordable technologies.
0:09:03 > 0:09:05Its first product was designed to treat jaundice which affects more
0:09:05 > 0:09:08than half of all newborns and its second effort
0:09:08 > 0:09:11was designed to help amputees who have lost a leg.
0:09:11 > 0:09:14Sumi Das has been finding out how these devices are helping
0:09:14 > 0:09:18the world's poorest patients.
0:09:18 > 0:09:21Their offices are modest but this team of engineers and designers
0:09:21 > 0:09:26in San Francisco is working on a bold goal.
0:09:26 > 0:09:29D-Rev exists to design and deliver quality healthcare products
0:09:29 > 0:09:33for underserved populations.
0:09:33 > 0:09:37Brilliance Pro is D-Rev's $400 phototherapy device.
0:09:37 > 0:09:40First launched in India it is an alternative
0:09:40 > 0:09:46to the $3000 units used to treat newborns with jaundice.
0:09:46 > 0:09:48You would see babies being treated under devices
0:09:48 > 0:09:51which have burned out bulbs, but also you would see
0:09:51 > 0:09:53multiple babies in one device which is not ideal
0:09:53 > 0:09:55to because you want to have the children
0:09:55 > 0:09:56separated for sterilisation.
0:09:56 > 0:09:58For affordability and durability D-Rev chose LEDs over
0:09:58 > 0:09:59compact fluorescents.
0:09:59 > 0:10:01They also ran optical modelling simulations.
0:10:01 > 0:10:05One of the things we have been able to use is use less LEDs,
0:10:05 > 0:10:08tightly control the wavelength and there are new lenses out
0:10:08 > 0:10:11so we can actually have a very even spread of light.
0:10:11 > 0:10:15If you are a doctor or nurse you might need to move this panel
0:10:15 > 0:10:16as you are caring for the infant.
0:10:16 > 0:10:19Of course that changes the intensity of the light
0:10:19 > 0:10:21but they accounted for that.
0:10:21 > 0:10:24They added accelerometers which detect the position
0:10:24 > 0:10:28of the LEDs so that each one automatically adjusts
0:10:28 > 0:10:33and the distribution of light is even across the baby's body.
0:10:33 > 0:10:36As with medicine it is crucial infants get the right dose of light
0:10:36 > 0:10:39therapy so a light meter was added.
0:10:39 > 0:10:42To date over 117,000 babies have been treated with Brilliance units.
0:10:42 > 0:10:5099,000 of those would not have retrieved any treatment at all.
0:10:50 > 0:10:53D-Rev's latest product is a knee joint.
0:10:53 > 0:10:56The ReMotion knee is a polycentric knee for above knee amputees.
0:10:56 > 0:11:00It's like a four bar mechanism which mimics your
0:11:00 > 0:11:02natural human gait.
0:11:02 > 0:11:05The previous option a single axis knee swings much like a door
0:11:05 > 0:11:08hinge and is less stable.
0:11:08 > 0:11:11The polycentric knee the centre of rotation moves so this man can
0:11:11 > 0:11:16continue working as a contractor and supporting his family.
0:11:16 > 0:11:21And this Indian teenager can keep up with his friends.
0:11:21 > 0:11:25In the US polycentric knees start at around $400.
0:11:25 > 0:11:28ReMotion sells for $80.
0:11:28 > 0:11:31Philanthropic grants help keep prices low.
0:11:31 > 0:11:36But D-Rev also credits it start-up tendency of working efficiently.
0:11:36 > 0:11:39Bug fixes included sharp corners and edges which didn't look
0:11:39 > 0:11:44natural underneath clothing and a distracting clicking sound.
0:11:44 > 0:11:48Fabric can fall smoothly over it and it has a rubber bumpers so it
0:11:48 > 0:11:51doesn't make as loud a noise.
0:11:51 > 0:11:54ReMotion has limitations, it is best suited for younger
0:11:54 > 0:11:57amputees since it's not as stable as other knees and the maximum
0:11:57 > 0:12:01weight for users is about 80 kilos.
0:12:01 > 0:12:05Still it's a good fit for many patients in Asia and Africa.
0:12:05 > 0:12:08It has a wide range in motion, much wider than most of the knees
0:12:08 > 0:12:11on the market especially in Western societies and the reason
0:12:11 > 0:12:15is that we saw with our users that they were squatting more
0:12:15 > 0:12:19or bending in prayer or kneeling.
0:12:19 > 0:12:22Many people need to ride a bike to get to and from work.
0:12:22 > 0:12:25Since the knee launched in December 2015 200 amputees have
0:12:25 > 0:12:28been fitted with them, that is 200 people who can go
0:12:28 > 0:12:35on working, learning, living - one step at a time.
0:12:41 > 0:12:43Hello and welcome to The Week in Tech.
0:12:43 > 0:12:46It was the week that the giant Chinese bus which drives
0:12:46 > 0:12:48over traffic went from concept to prototype.
0:12:48 > 0:12:51Moon Express became the first private company to get permission
0:12:51 > 0:12:54to land on the moon from the US government, whilst virgin
0:12:54 > 0:12:56Galactic SpaceShip Two received permission to take
0:12:56 > 0:12:57tourists into space.
0:12:57 > 0:13:01Instagram released its stories which look a lot like Snapchat
0:13:01 > 0:13:05stories, and Samsung showed off its Galaxy Note 7 fablet
0:13:05 > 0:13:09which includes an iris scanner so you can unlock it with your eyes.
0:13:09 > 0:13:12It was also the week we saw a video from MIT that you can
0:13:12 > 0:13:14reach out and touch.
0:13:14 > 0:13:16Which scientists said could have applications
0:13:16 > 0:13:18for games like Pokemon Go.
0:13:18 > 0:13:21The concept is called interactive dynamic video and uses cameras
0:13:21 > 0:13:25and algorithms to track almost invisible vibrations of objects
0:13:25 > 0:13:28to let them be interacted with.
0:13:28 > 0:13:31This augmented reality is getting pretty good.
0:13:31 > 0:13:35Speaking of Pokemon Go the game hit 100 million downloads this week
0:13:35 > 0:13:37and was also hit with the trespassing lawsuit
0:13:37 > 0:13:39from a man in New Jersey.
0:13:39 > 0:13:43He said at least five trainers had knocked on his door looking to catch
0:13:43 > 0:13:46pocket monsters in his garden.
0:13:46 > 0:13:49And finally if you ever wondered what a robot with a neural
0:13:49 > 0:13:55network would sing like, I know I have.
0:13:57 > 0:14:00Meet Alter, the latest humanoid robot from Japan has 42 pneumatic
0:14:00 > 0:14:04actuators and a central pattern generator which replicates
0:14:04 > 0:14:08neurons at Alter create its own patterns and react
0:14:09 > 0:14:17to its environment and sing.
0:14:19 > 0:14:22Now, every year in the middle of a desert thousands of hackers
0:14:22 > 0:14:26and security experts meet to talk shop.
