proximity sensor RRS feed

  • Question

  • Hello everyone

    I am working on a device which is an ultra-sonic proximity detector functioning as a USB keyboard. The primary
    purpose is for detecting users stepping away from a computer terminal they have un-locked (log-in active), and issuing keystrokes to lock or log-off the session on the computer.

    How can i detect the user's position with respect to the device in c#?
