The Apen Touch8 Cordless Pen Can Turn Old Monitors Into A Touch-Screen
Based in West Covina, California, E Fun has developed a cordless pen called the Apen Touch8. The Apen Touch8 works with an attachment that gets plugged into a USB port on a Windows computer. From there, the Apen Touch8 turns a monitor into a touchscreen by using an infrared and ultrasonic receiver that clips magnetically to the side of the screen.
The screen can be as large as 17 inches (43 cm.) diagonally. The pen has an infrared beam signal that gets sent to the receiver attachment. When pushing down on the pen, an ultrasonic signal is transmitted.
The Apen Touch8 uses a watch battery that should last around 500 hours and is replaceable. The Apen Touch8 will be available by the end of March for $80.
