Electric Field Tomography – Electrick  – you can turn a wall, a phone case, a steering wheel, a toy or anything into a touch sensor with the help of just a little spray paint and some electrodes they figured it out at carnegie-mellon let’s take a look adding touch interactivity to objects, these easy first we add a conductive coating to an object then we attach sensing electrodes to the periphery of the desired interactive area an optional topcoat can be applied with this setup electric can detect different touch locations as well as enable course continuous touch tracking our sensing principle works by injecting a small electric current into the conductive layer using a pair of electrodes, we then measure the voltage at all other adjacent electrode pairs when a finger touches the surface some current is shunted causing a localized reduction in voltage to better estimate the touch location we rotate the current emitting pair and repeat this process this results in a mesh of cross-sectional measurements using tomographic reconstruction.
Create a 2d touch sensing
we can create a 2d touch sensing image revealing finger locations so with this all you would need is that conductive paint the electrodes touched the bottom and using the shunting technique which would send a small amount of a small amount of electric current to the ground couldn’t turn nearly in a shape into a touch pad so this could be used maybe for an entire wall it could be used to display things to maybe teach people kids could learn in a very literally hands-on way so it’s super easy a whole wall or anything  or anything. You could just take something that’s the shape of a game controller turn the whole thing into the touch pad put a little mat over it with Windows and suddenly whatever that you have a remote control yes it’s mean it’s just amazing well think what we can do even for the consumer levels so like smart phones or smart phone cases even.
you could have that level of control besides just touching the screen or you know it kind of works like a touch screen but it’s not nearly as expensive as having a touch screen maybe this would be a solution if you badly cracked your phone which a lot of us are known to do yeah there’s just or even the back side of it I know many smart phones do have a sensor there but this would be able to convert the entire back of the phone right they were saying the way that you hold the side of your phone would inform what app it opens immediately so if you rate if you hold it like this it’s probably gonna be turn into like snap chat uh-huh you hold it this way it’s gonna be your camera it’s amazing  I see I love every bit of  it and then also if you have some kind of transparent conductive paint on it right then you can put a screen behind it and you replace the entire mechanism at work that probably is a good amount of what’s inside your phone to make it a lot thinner or plot more pliable.
I love this a lot because it’s an affordable way to do touch so you could do that whole wall and not spend I don’t know how much money to make an entire wall a touch screen yeah they also had a if you have a steering wheel so you can thinking of these applications swipe left swipe right if you want to turn your music up you just go like that you know down up over the outside of your wheel this could add to so many different applications they like this better than haptic technology so this came from CMU Carnegie Mellon University PhD student yang Zhong and it’s called electric you can his suggestion uses include wood plastic drywall jello play-doh it’s amazing, I don’t know about spraying  jello but because I would definitely break a chunk off but with play-doh that would be awesome as well I don’t it’d be amazing to sculpt something and see what kind of out push this would be able to create.
I wonder the toxicity level of whatever well it’s a pencil meant right but what you’d have to hit that you know nice little intersection of things  are  aesthetically pleasing and also non-toxic, so currently this will be shown at the conference on human factors in computing systems in Denver it’s not at the consumer level yet but if it were what would you do with this requires some thought because it’s just like opening or taking down those barriers of what you think you can use for touch sensor technology I know in the past there  have been kick starters for turning anything into a game controller but this would be another level of that even of computing or consumer facing even like phone technology which we all have we all rely on let’s take it to that next level .
