Web-Based Utilities
This web-based utility will help you determine if the object you're detecting with the Si114x proximity and ambient light sensors will be within range, and if the SNR threshold is high enough to trigger a detection event. This tool can determine if you have adequate SNR in less than a minute.
This current estimator utility will help you determine how much current is required for your application. Specify whether you need proximity light sensing, ambient light sensing, or both. Choose your channels, and view the estimated average current results in real time.

White Papers
Unlike human-to-human gesturing, human-machine gesturing does not have a foundation of thousands of years of history to serve as a context and this poses a challenge for human interface system designers. How does a system designer minimize the pain of “learning” gestures for the user?
The availability of enabling technology that can revolutionize the way we interact with consumer electronics products and an urgency to incorporate this technology demonstrates the increased importance consumers are placing on interface design. What defines good human interface design, and how can system designers implement a smarter, friendlier and more intuitive solution?
This in-depth white paper examines how through advancements in human interface (HI) technology and design, infrared proximity sensors are poised to usher in the next user interface paradigm centered on touchless gesturing.
Next-generation products require next-generation human interfaces to differentiate themselves in the marketplace, and two of the primary technologies driving this interface development are capacitive and proximity sensing. This white paper addresses the 3 most common challenges when designing human interfaces: power consumption, system responsiveness and interface control.
Choosing the right USB communications option depends on several factors, and each solution has different requirements and degrees of flexibility for both the developer and end-user. Is development of USB firmware or drivers required? Does the end-user need to install a driver? Is a PCB redesign required? How much PCB space is available for additional components? Download this white paper to determine the easiest, most cost-effective way to add USB communications to new designs or a legacy system.
Imagine being able to control electronics products at home and in the office, not with a direct touch but with the sweep of your hand. Advanced “touchless” human interface technology is now within the realm of practical implementation, even for products as commonplace as the alarm clock beside your bed. This white paper shows you how you can add touchless gesture interpretation like set and swipe detection to your application.
In many applications, mechanical push button switches and potentiometers are being replaced by capacitive switches, sliders, and control wheels to implement functions such as contrast, volume control, and power on. In this tutorial we’ll explore how to design the user interface of ultra low power applications using capacitive sensing technology, with a specific focus on system definition, hardware design and firmware design.
