I tried glasses has been around for you know twenty-five years or more but you know they have been better longer ,you're on like big backpacks and stuff like that.but what's happening now is that you know, they are getting smaller need a and getting less intrusive.But you know ,again I tried can't stand alone.So you gonna you want to know what is the emotional response ,when people stand up shelf looming at this or that when they shit in a cow ,that's of course all kinds of research.So what is really exciting about this now is that with this kind of platform you can actually synchronize directly with high edg for example, so you can basically measure the Congress why you know exactly what people is looking but in a much more real life scenario and that's really going check off all the next couple of years so that everybody  know all the retail company is all the people that is going to test if things pop on the shelfonly if they see it but what is the emotion reaction of what's the cons of work do they actually understand that's the product.That's going to be a huge game changer now how does that work.I'm not out of it how does actually work.So you say you send people inside the store they get to a specific point with the shower from his supporters on the shelf how do you actually know that I tracking then you can go and you can see if people are looking at this particular product and then what how can use an extract how do you how can extract the imotion responsible.I mean you can put a headset on them while they walk around with it so basically you can sit.let's say that you're doing your study,then you can see it you know when you start them to go with their shopping cart.then you can basically a shit life and observe what the imotion responses are and mark different place of days even know,a hypno system not only for the mobile system,and then we use we have tools to really find out.like what we call narrow interest exactly ,when people they look hear that product,what is the imotion impact and that's what you can do it on our society where you be going and really find out only the watch response when they looked at a specific place.tracker on me now and I could draw an area of interest on your face but also on your maybe something third here and I will be able to extract information from them every time when I only look at this look at the only.three different columns exactly right executive sort so that's kind of just make you know very easy to get access to that and when you talk about a lot of days .So we were get mean its more than two hundred and fifty six missions per second and you know across a lot of channels right I mean there's a depending on what kind of edg said you and so on.That's just a talking very big day to hear so these kinds of tools that you can I got the right.To get them smaller than humongous is really really important and that makes it possible for you to kind of very quickly make.and analysis and video scripts and small software to do that.
