The first Android 2.3 ever developed was made by E. A. Johnson at the Royal Radar building. It was a capacitative android tablet as next to a resistive , the same used in the Apple iPad today. An original adaptation nearly wouldn't aid pinch to zoom, but multi touch is now popular on touch screen devices. The solution has expanded hugely and resistive touchscreens begun to achieve some attractiveness, even in the cellular sector. Resistive touchscreens are constructed of layers that are applied, one after the other. The anxiousness is discovered as the layers compress into one another. Resistive touchscreens, are more commonly used in tablets like the Cintiq. The Cintiq is a graphics tablet hybrid that is required intensely in the cartoon industry for movies like Kung-Fu Panda, Cars 2 etc. Back in 1967, Johnson figured it would be a great idea to assist with radar guidance systems, he even published two papers about it. Touchscreens have been with us ever since, but not always as a capacitive. The fact is, the video below is of the HP-150, which was released in 1983 and sold for $2795.
