The purpose of touch screen technology is to give its users an interface that is both effective and intuitive. There are two tools in the world that we rely on most for the manipulation of our environment, the expression of our creative minds, and any matter in between. This is why everyone got so excited with the emergence of multi-touch technology. But when it comes to touch screen laptops, this feature is only available with very select high-end models. That is, until N-Trig released the DuoSense™, the only digitizer in the market that recognizes the pen, touch, and multi-touch.

The product fits over any laptop screen to convert your regular non-touch screen laptop into a fully functioning pen, touch, and multi-touch enabled screen. The product is very well designed noninvasive thin screen that fits over the laptop nicely. It can be held into place with air gap bonding, PSA, or direct bonding and uses a gel to minimize reflecting glare. That allows the user to function perfectly unaffected by the brightness when outdoors.

The pen itself is quite the work of wonder. It has an electric-magnetic charge in itself that interacts with the screen without the need for an external power source. The pressure sensitive tip recognizes the difference in the strokes and taps of the user. During artistic functions, heavy and light strokes are digitized on screen in a manner that intuitively mimics a pen or brush stroke. It even has eraser capabilities when used in drawing or writing programs. Outside of drawing programs the stylus serves well in navigating. The DuoSense allows the use of the pen in much the same way as a computer mouse with right click capabilities.

The touch technology uses fractional pixel recognition for the most pinpoint accuracy in touch response. The capacitive design of the touch screen eliminates the use of traditional touch screen spacer dots that compromises the accuracy of the pen. It offers the fastest response time in the history of touch screen technology and there are no accidental drops with the click and drag function and the touch pad comes with what the company terms the palm rejection feature. It recognizes the difference between intentional and accidental touches.

The DuoSense is light and thin for easy integration over a regular laptop screen as well as clear to allow for much of the screens brightness to shine through. Most touch screens suffer from degradation of the monitor's true brightness but the DuoSense engineers made sure to minimize that effect while still providing advanced touch screen laptop functionality.
