There’s very little doubt that touchscreen computers are among the most popular gadgets around these days. Tablets like the iPad have certainly played a large part in making touchscreens more popular than ever before.

The fact that touchscreens harken back to popular sci-fi shows like Star Trek doesn't hurt their popularity either.

Lenovo has even come up with a giant touchscreen computer that can double as the biggest tablet out there, or merely a desktop that can be piloted with a mouse or your finger tip.

But what about people who have older desktop or laptop computers that aren't equipped with a touchscreen? Turns out, CES has birthed an answer to that problem.

E Fun has come up with a digital pen that works alongside the Microsoft (News - Alert) Windows 8 operating system and will allow any computer running Windows 8 to behave as if it were a touchscreen. Obviously the pen is quite a bit lower priced than if you were go out and buy a touchscreen computer all on your own. 

The Apen Touch8 was unveiled this week at the Consumer Electronics Show (CES (News - Alert)) in Las Vegas as a cordless pen-type stylus that includes an attachment that plugs into the USB port of the Window's computer.

The attachment then acts as an infrared and ultrasonic receiver that clips to the side of the screen. The pen portion of the device shoots out an infrared beam taken in by the receiver and sends it onto the computer, allowing the computer to get the precise location of the pen, which is now basically acting much the same way as if you were using a mouse to move a cursor.

Pushing down on the pen sends a signal much like that of clicking the mouse buttons.

The Apen Touch8 is expected to be available to the general public in March for $80. That means that while it is cheaper than buying a new computer, users are really going to want to have a touchscreen to shell out the money.
