There are already tools like Pushbullet and AirDroid that allow certain interaction with your Android device whilst you are physically away from it, but now a new application called Vysor aims to take that one step further.
Koush, the same developer that brought apps like AllCast and Helium, has developed Vysor that is essentially a Chrome extension that will talk to your Android device over ADB. That does mean you’ll have to plug your device into the computer for it to work, but here’s hoping functionality may be introduced at a later date to make all this happen OTA.
When your device is detected by Vysor, it opens a floating resizable desktop window that mirrors the screen. You can click and drag to interact with your device and it is incredibly responsive.
It’s not quite finished yet and the Beta tag certainly applies here, but if you’d like to try it out, you can grab the Chrome extension here.
