 Early data, what is this? This is an IntelliQey's assistive device which has a matrix of touch switches behind it and then these swappable overlays and each overlay is like a little bit different. You see this one has like mouse and keyboard, quarter keyboard and this has like a bigger kind of Alfa Numeric keyboard and it uses a photocell to determine which overlay you have installed. And this is a really useful device but unfortunately it's no longer supported and the driver downloads firmware over USB from the computer like a Windows computer and so if you're not running like Windows, maybe it runs on Windows 10, but other devices like Chromebooks or tablets with mobile can't use this because they don't have that driver firmware to download into this device but what we can do is use one of our USB host feathers and what this does is HID translation so this chip enumerates the IntelliQey's through the USB connection downloads the firmware and then asks it what overlay it's got and tacked an amazing job reverse engineering the original driver and then to connect it to something like an iPad you would connect using what's called like a camera kit and here I've got like the notes app up and then you just give it a second because it needs to download that firmware it'll beep when it's ready and then you can type on this and it shows up just like keyboard input so hello um i space oops i space m space it's tough to type on a telly all right good enough to work working
