Kona Currents, LLC offers downloadable software and apps for creation, collection, processing, and management of optical visual markers. We call these a Semantic Marker® This incluces An innovative text and optical search engine, along with an API for processing optical labels, barcodes and two-dimensional codes. These optical image and data files are downloadable for internal and external use. Apps also interact through published API's with our Cloud Computing services (various public download links below.)
Both public and private aspects of this GitHub include downloadable software for running the Internet of Things (IoT) devices, including the new ESP-32 family of embedded processors. The areas of processing include app software for ESP-32 and mobile devices (i.e. iPhone, watch, TV, etc). This also includes code for the cloud service processes. These are a mix of web servers (i.e, Apache Tomcat, and Nodered), also powerful messaging capabilities (including MQTT, Websockets, HTTP, DDS, telegram, etc.)

New for 2024: Semantic Marker App in Apple App Store
Kona Currents, LLC introduces a new approach for interacting with our technologically rich environment - such as Smart Devices and Internet of Things (IoT). Special optical visual markers, we call a Semantic Marker® such as two-dimensional code images and barcodes, come alive through interactive fee dback with the environment; continual scanning will send secure internet messages to IoT devices (like to the IoT dog feeder in video) and even show unique interactive Augmented Reality graphic overlays based on contextually and semantically relevent information (can you say Minority Report!).We humans (mostly) use our Visual
skills to make sense of our environment.
But we also use Optical
tools to enhance (or even make sense) of the same visual environemnt. For example,
an optical telescope brings things closer for better understanding (like Planets or climbers on a wall._
Vision recognition of faces or text is also useful. The
advantage of a visual two-dimensional code is that special optics can now translate the
image into perfect information. So our vision is extended with optics
resulting in an Optical Visual Marker - or our Trademarked
name: Semantic Marker®

This app provides a multitude of capabilities centered around the Semantic Marker® capabilities. This includes scanning a Semantic Marker® and sending a message to the named dog feeding device over bluetooth. Here the Semantic Marker® is sent to the watch through messages. Clicking expands to show the Avatar image while hiding the machine readable portion of the Semantic Marker®. Here our unique SMART Button framework is creating the Avatar image from information gathered in the secure messaging network.The following shows the (small) ESP-32 M5 Device using software developed by Kona Currents, LLC, to support the Semantic Marker® optical visual marker infrastructure. This is actually a continually changing Semantic Marker® image reflecting the changing sensor values. The Augmented Reality overlay from the iOS App would show those changing values, otherwise a static web page would just show a snapshot. The Semantic Marker® optical visual marker is unique in the amount of information that can be encoded in an image, contrasted with trying to display similar information in this small display (think of the movie Matrix and the moving green images.)
The download for ESP-32 devices includes the software for what is shown in the image.
