If your laptop doesn’t have a touchscreen, you don’t need to replace your whole computer to get the functionality. Here is the solution that will change your laptop into touchscreen laptop. Yes, It is possible with the help of single stick device called Airbar from Neonode.
Airbar fits just under the monitor display. It’s a thin, black rectangle that rests on the bezel underneath the screen – if you have a black or gray laptop, you may not even realize that it’s there. It uses invisible light to detect where your finger is on the screen and provide that feedback to the computer.

Neonode says that the AirBar will work with laptops running Windows or Chrome OS. The AirBar will come in four sizes to support most displays: 11.6 inches, 13.3 inches, 14 inches and 15.6 inches. Probably, all sizes are same price.
The device is plug and play – plug the AirBar into a USB port, align it on the screen, and you’re ready to touch. In a painting it can track your finger accurately as you draw on the display of a laptop without traditional touchscreen capabilities. You can use other objects, including a paintbrush and a chopstick.
