What do you mean? You can you a arduino to interface with a laptop computer. I say this because the Arduino is a computer too just not very powerful. But anyways Arduino is much better than a laptop at reading raw sensor data with it's raw I/O pin ports. What you can do is program the Arduino to detect a input then interface the arduino with the laptop through USB and using serial communication, then having a program on the computer that can read the Arduino's serial data then perform a programmed action on the computer.
I hope you know what I mean.
