What does Intel virtual buttons driver do?

[harihar akhil]

I have seen many pcs with Intel virtual buttons installed which I clearly have no idea what it actually does. Googled it and all I could find are the oem's download page for that driver rather than any description of what actually it is? So can any one explain what actually it does?

Intel Virtual Buttons software allows the virtual buttons to adjust correctly when the screen rotation of the tablet is changed after the system is connected to or disconnected from the docking base. Intel Virtual Buttons also communicates button or indicator state changes to the operating system.
