to compensating customers. coming up in 10 minutes‘ time, news watch. but first on bbc news, click. this is nelson's column in trafalgar square, and for over 150 years its base has been guarded by four giant lions. but soon these guys will be joined by a fifth — and a rather unusual one. it is arriving with the help of google and paul carter went to find out more. protest, celebrations, mourning. trafalgar square has long been a place where voices come together. the lions which have sat in the square since 1867 have heard them all. what if they could speak? as part of the london design festival, a fifth lion will appear in the square, powered by machine learning. the result is an interactive sculpture called please feed the lions, a collaboration between designer es devlin and the google arts and culture lab.

members of the public will be able to feed the lions with words, which in turn will generate poetry created by an artificial neural network. it uses an algorithm known as long short—term memory recovery neural network. snappy. it has learnt how to write by reading millions of words of 19th—century poetry relevant to the time the lions were first installed in the square. machine learning becomes a way not to replace human poetry writing, but a way to allow people who wouldn't normally be able to write a poem, or wouldn't normally think of writing a poem, to enable them to gather their words together and form a collective stream of thought, to add order to what could otherwise be chaos of people jamming together their thoughts. and you don't have to go to the square to take part in this. you can go on to the website and contribute online as well. it is notjust for londoners, that is important to me. the algorithm works by learning to predict the next text character over and over again,

always taking into account those that came before, similar to predictive text, repeating this process until the condition accurately sequences words it hasn't seen before. when members of the public feed in their own words, the machine will expand them into its form of poetry. once the poems have been generated they will be projected onto a screen in the mouth of the lion, and when it gets dark, onto nelson's column. hang on a minute. isn't asking members of the public to input their own words asking trouble? we have applied filters, so, filters where all of the words have to be in the oxford english dictionary, and then there are filters against offensive words. and if you try to enter words that the lion is not happy with, it will simply tell you, i am unable to digest those words, please try again. so, with aland machine learning becoming more commonplace in the arts, what does the future hold for the relationship tween art and technology? does technology make sense?

does it add a value? if not, then, you know, leave the art alone. but if it can be a tool, a creative tool, perhaps, or perhaps a collaborator, and i would say with the case of the lions it is both a tool and a collaborator, or perhaps it enables the arts to be accessed and experienced more broadly. sarah?! sarah!! lady, hey, lady! i found her! it's every parent's nightmare — losing sight of your child, even for a few seconds, can be terrifying. and in hte dystopian future of black mirror, it leads this mother to implant her child with an all—seeing monitoring device. one slightly less invasive solution is to give them a smartphone,

which means they are contactable and trackable using gps and, in fact, 83% of young teenagers in the uk now own a smartphone which, of course, raises that spectre of device addiction from an early age. so what if you had a way of knowing your child's location and communicating with them without the need for a smartphone? enter the norwegian xplora smartwatch, a children's wearable with an inbuilt sim card and a gps locator. parents can keep track of them on their app, and will get an alert if the child leaves a pre—defined safety zone. it also acts as a phone, allowing a child to ring and receive calls and texts from trusted contacts or send an sos if they feel in danger. sounds like a good idea, but wherever there's tracking, there's the worry of hacking, and the boss, jesus llamazares, admits it's a very sensitive issue. as a parent with young kids myself i want to know they are safe and want to know

where they are, but i also don't want anyone else to know where they are. there is the worry of hacking with any kind of location tracking. yeah, we have been working intensively with the data protection agencies in norway and germany, and also with a third party, a world recognised certifying partner for security services. do you think there is a danger we are moving towards a society where we are happy to constantly surveil our children and family? moving towards a world where there is no privacy? do you think there is an age at which kids do not need to wear this kind of device? these devices are designed for kids below the moment they have a smartphone. there are also some new cases that we try to promote all the time around health, that is, if your child is going to a football match or doing some activity out in the air, sometimes a smartphone is not the best thing to wear, but a smartwatch is able

to keep you connected, right? so there are some new cases, even for teenage years, where the watch is quite useful. the increasing worry is that the kids have all the time with the tablets, with their devices, and we want them to go out and play, not just be connected, with the family, no access to social media etc, but as well, the outside, in joy and experience out of your home, right? with your friends and your family. but being all the time with their tablets. of course they will still have a lot of time with the tablets, smartphones, consoles, et cetera. now, i think it is fair to say we have a pretty fun job here at click. but there is one company which dedicates a whole day every year to letting its employees simply play. kate russell went to see just

what difference that can make. the late great sir george bernard shaw is said to have said, "we don't stop playing because we grow old, we grow old because we stop playing." i came to lego headquarters in london to find out more about the science behind play. for lego employees, the seventh of september is play day, when they take time off from their normal duties to have fun with the products at the heart of the business. i think the play day is a time for us to get back to understanding our own motives, get back to understanding why we are here, the department that you are in, to think about the fact that i might be in r&d, i might be in finance, but at the end of the day i am here to get the smile on kids‘ faces. you'll get no argument from me that day of play is good for the spirit, but is there a scientific reason it could be good our health? that is the question scientists at the university of london want to answer. so, this is a unprecedented project to try to understand the effect of play. we have a controlled environment at the beginning,

a regular workday, and then we have a play day where they are exposed throughout the day to a variety of interventions. then we have a day afterwards, in which we can examine the residual affect of the play day on the individuals. today they are running a proof of concept pilot to see what results a serious study might turn up in the future. a small group of volunteers have been connected to heart rate monitors to measure the physiological effect of stimulating play throughout his series of different activities. they will also be self—reporting the psychological effects by answering a series of specially designed questions through a chat bot. ian is the man with the tech. what is that? this is a high—resolution heart monitor. it's 1000 hertz. you put it under your top, in contact with the skin, put that around the back, and clip it on. brilliant.

and go play. if i must! i am a big rollercoaster fan, and what better way to get your heart racing? i recruited mini me and mini spencer for some good old—fashioned play. critics claimed that the brain controls the speed of our heartbeats based on what's going on around us. when we need greater concentration or to handle stressful situations it speeds up the heart, increasing blood flow. the heart slows back down again when it enters a period of rest and recovery. it looks like mini spencer might need a longer period of convalescence after that right. spencer: yeah, i was bricking it, to be honest. what are the results you expect to get from the baseline versus the play day with our lego people? so, what we're expecting to see is really getting to gauge that. the scores will go down as they need more energy, more concentration on the really difficult tasks. and really good recoveries as well, because they are enjoying it. so once they have had that stressful moment they should be able to bounce back and recover quickly for the next one.

if you are constantly stressed and on edge, you won't experience the peaks and troughs associated with healthy brain—heart activity. there is a different between acute stress and chronic stress. acute stress you expect, if a lion pops up behind you, fight or flight is the right response. if you have long—term stress, chronic stress, that can be much more negative indication. i think everybody is really excited now. there is a whole renewed energy worldwide around well—being in the workplace and trying to understand how we can better motivate and engage with workforces and employees, and i think play is an interesting and innovative way to do that. the results are in from this pilot and they suggest certain types of play could help workers recover more quickly from stressful periods. crucially, they might help raise levels of confidence and creativity in certain personality types. i guess i am the type of personality that would quite happily sit in a spinning top all day. spencer!

can we get one of these in the office, please? so that is what is rofl means: rolling on the floor laughing. yes, we will get one for you, kate. don't forget, we live on facebook and twitter. thanks for watching. see you soon. hello and welcome to newswatch with me, samira ahmed. the bbc has decided not to appeal against the courtjudgment that it seriously infringed the privacy of sir cliff richard. and worse monday's all within panel just a stunt? parliamentarians came back to work this week after their summer recess to be back to work this week after their summer recess to be greeted by a new daily programme on bbc two presented byjoe cockburn. daily programme on bbc two presented by joe cockburn. it's monday, its 1215 and we live in westminster. politics live takes over the slot.

it only lasts for 45 minutes except on wednesdays when 1.75 hour programme includes live coverage of prime minister's questions. the uk wide sunday politics has been scrapped, a decision which bemused viewer grade. it was also some criticism, levelling the charge of dumbing down. john took exception to the use on

screen of audience reaction to what the guests were saying, asking: dave smith declared himself very impressed. the biggest controversy over politics live, one which even hit the pages of the sun newspaper, was prompted by the line—up on monday's first programme. joining me today, former home secretary amber rudd, shadow foreign secretary emily thornberry, the telegraph's camilla tom
