sensor in USB HID KEYBOARD

[jain1.anuj]

hello,
i am working on a USB HID device. it's a proximity device which detects the person's distance and fire keystrokes accordingly.
i am using Hid.dll , Setupapi.dll , kernel32.dll for read/write operation.
i want to detect the distance of the object by using proximity sensor. is there any API present in .NET for this purpose?

HID reports can contain data for any purpose. You can define your own protocol for what the data in a report means and write an application that reads the reports and takes the desired action.

To emulate keypresses, see:
