INTRODUCTION
zForce is Neonode Inc’s innovative optical 2D touch technology.
zForce is an abbreviation for “zero force necessary”
It gives a number of major advantages compared with traditional touch technologies, like capacitive or resistive.
With zForce, any type of screen or display can be used.
In fact, zForce works with any surface – flat, round or any other shape.
Another advantage is that any type of object can be used – a finger or a stylus, a car key, fingernails, gloves and ordinary pens.
E-ink technology
E-ink technology allows the text to be readable even under direct sunlight.
It has ultra-low power consumption, and is not as strenuous to the eyes – almost like a real book.
Unfortunately, e-ink screens by themselves are not touch-sensitive.
That is why some people are drawn to tablet pc’s that enhance the reading experience by adding touch features.
But they don’t offer the benefits of e-ink mentioned above.
Basic Concept
zForce technology is based on light fields.
As the light is interrupted by fingers or objects, the system notes the position.
Other objects than fingers are therefore possible to use, since the screen responds to any type of material.
Working Principle
zForce consists of a set of infrared emitters and detectors, an optical light guide, control electronics and control software.
The emitters pulse infrared light just above the touch surface.
A change in detected light indicates an object touch.
By combining the measured value from more than one detector, the touch position and object size are calculated.
The output from zForce can be used to identify actions such as gestures and sweeps.
