zForce Sensor Modules and Evaluation Kits

The Neonode sensor module is a laser light based touch sensor based on light reflections that can be integrated and used in various applications. The sensor modules detect and trace objects by detecting diffusely reflected infrared light. An object present in the active area will affect several receiver channels, and the reported x/y coordinates are the outcome of a center of gravity calculation on these signals. The sensor modules connect to the host system through a standard connector and communicate through a standard I2C or USB interface.

The characteristics of the sensor modules are high scanning frequency, low latency, high accuracy and operate in the temperature range -40°C to +85°C, making these sensor modules ideal for applications intended for harsh environments.

With Neonode sensor modules you enjoy complete freedom of design, ease of integration and cost-efficient production.

Neonode ZForce® Technology Overview

ZForce® (zero force) is the name for Neonode’s patented optical sensing technology built on infrared light, invisible to the human eye. Neonode’s zForce optical sensing technology adds value and provides the highest performance for a multitude of devices. We strive to provide the highest level of functionality by adding unique features that only optical technology can realize.

ZForce technology offers a variety of competitive and original features that sense any type of object, determine its size, its pressure on a surface, its depth (3D), its velocity and even its proximity to any type of surface.

ZForce technology consists of a set of light emitters and detectors, an optical light guide with lenses and a controller IC that is connected to a host. The host runs Neonode´s proprietary embedded software stack and is connected to the controller. The controller IC regulates the light emitters that emit short pulses of light in an intended sensing/interactive plane. The controller continuously monitors the light that is collected by the detectors and checks the ambient light in order to calibrate the system to work in all light conditions. Objects in the light path of the sensor cause intensity shifts in the received light. This information is used to initiate tracking of the objects. The size and position of each object is reported back to the host. By combining the measured value from a number of detectors, the position and object size are calculated. Compensations are also made for dust and other small particles on the optical surfaces, as well as for variations in component quality.

Being light based means that zForce technology is robust to electrical noise and other electrically conducted interferences and to strong RF sources. Our controller ICs use sophisticated hardware filtering in combination with optical and software filtering to achieve a system that is highly robust to ambient light and other strong light sources.

ZForce technology has high scanning frequency, low latency and high accuracy, and operates in a wide temperature range, making it ideal for applications intended for harsh environments.

 

Optical Reflective Platform

ZForce optical reflective platform is based on light reflection technology, integrating optics and electronics in a thin strip along one side of an intended interactive area, creating a 2-dimensional interactive plane. 

Through its innovative use of infrared light, invisible to the human eye, zForce optical reflective technology interacts with the position and movement of any reflective object within its range. It enables touch interaction on any display or surface, mid-air interaction ranging from sweeping hand motions to multi-finger gesturing, as well as dynamic sensing of any object or environment.

Neonode has a new line of embedded sensor modules incorporating its optical reflective technology.

With Neonode sensor modules you enjoy complete freedom of design, ease of integration and cost-efficient production.

 

Optical Blocking Platform

ZForce optical blocking platform is based on light blocking technology and provide multi-touch interaction with a minimum of components and the lowest possible cost. It is tailored for ultra- low latency and power consumption and can be customized to fit any resolution, speed, power consumption or robustness in any application or environment.

ZForce optical blocking technology is for high volume applications that can be licensed. Custom design solutions are scalable to any touch area and size and work on any surface and with any touch object.
