The AirBar sensor, developed by Neonode, transforms non-touch PCs into touch interactive devices by emitting an invisible light field that detects disturbances, known as z-force technology. It easily connects via USB and supports various touch objects including fingers, gloves, and styluses with no need for additional drivers. AirBar is cost-effective, portable, and user-friendly, making it suitable for both consumer and industrial applications.

3. INTRODUCTION
 Developed in Dec 2015 by Neonode, a Sweedish company patented
in optical touch technology.
 A device that enables touch functionality on non-touch PCs running
Windows or Chrome OS operating system
 Transforming non-touch screen Laptops into Touch Interactive
Devices.
 This is a sensor working with your PC. You can unplug it when you
want to.

4. HOW TO USE?
• Very simple, just plug and touch.
• Familiar touch actions like swiping, pinching, zooming and
scrolling.
• Works whether you're using your bare finger, gloves, or any
other object.

HOW DOES IT WORK?
• The device emits an "invisible light field" across the screen, which
detects any disturbances made within it, Known as zForce AIR
technology.
• It responds not just to bare fingertips but also to objects such as styluses,
brushes and gloved fingers.

6. Z-FORCE TECHNOLOGY
• zForce means zero force.
• zForce is an award-winning optical touch technology. Based on
optical infrared light.
• With zForce, any type of screen or display can be used. In fact,
zForce works with any surface – flat, round or any other shape.

7. Z-Force technology consists of
 a set of light emitters and detectors,
 an optical light guide with lenses and
 a touch controller IC that is connected to a host.

8. Basic idea
 The emitters pulse infrared light just above the touch
surface
 A change in detected light indicates an object’s 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.

Working
• Light emitters send out short pulses of light just above the touch
surface.
• The touch controller continuously monitor the light that is collected
by the detectors.
• The size and position of the touch object (i.e. a finger) is reported
back to the host.
• By combining the measured value from a number of detectors, the
touch position and object size are calculated.

12. Advantages
• There is no requirement for a layered glass or plastic film that
overlay the display surface.
• zForce technology almost is immune to electrical noise and other
electrical conducted interferences.
• zForce products work with any type of touch object such as a finger,
a stylus, a fingernail, a glove or an ordinary pen.
• Compensations are made for dust and other small particles on the
surface as well as for variation in component quality and ambient
light conditions

14. System requirements and specifications
Functional Requirements:
• The device should make the system touch interactive.
• The device should be immune to unwanted environment.
Non-Functional Requirements:
• Cost: The cost of the device should be low.
• Reliability: AirBar has high reliability with the help of Z-Force
technique.
• Portability: AirBar is portable.
• Usablity: AirBar is very simple to use. Just plug and touch. 14

15. Software Requirements:
• Although, the AirBar doesn’t have some specific software
requirements, but, the device has only been manufactured for
Windows or Chrome OS operating system
Hardware Requirements:
• According to the company, users don't need to load drivers, perform
a calibration or jump through any other hoops in order to get AirBar
to work.
• The AirBar logs on as USB HID device with the operating system,
so no drivers are necessary.
• just stick it on the PC, plug it into a USB port, and it starts
functioning.

17. Conclusion
• Neonode’s optical infrared touch technology, zForce, can be
integrated into consumer and industrial electronics to enable touch
controls.
• Imagine taking a non-touch PC, and within seconds making it a
touch interactive device. AirBar will help you in doing so.
• Just plug it in whenever you want the touch to be enabled on your
laptop and you are on.
• AirBar is cost-effective and comes in different sizes.
