We all (roughly) know how to naturally converse with one another. This is mostly subconscious and only really noticeable if an interaction skews from what most consider “normal.”

In the majority of cases, these are just minor differences, such as someone speaking a little too close or interrupting more often than usual.

However, more significant conversational differences can start to occur when parts of the brain begin to decline in performance.

Augmented reality (AR) has definitely come a long way. The app Pokémon Go was arguably the first AR game that truly allowed the concept to go mainstream.

Today, videos with Instagram and Facebook AR filters have become standard content in everyone’s news feeds. For businesses, this means engaging in the AR space.

When it comes to boosting your social media marketing strategy with AR, the first thing to understand is that it has become much easier and cheaper to do.

In order to understand computer vision, we must first understand how we’ve evolved to see the world. Not only is it important to investigate how we see but why our sight evolved this way.

We use computer vision in some of our solutions at Wallscope, so it was important to start from the beginning and ensure I had a solid understanding.

In case you missed the introduction to this series, Joseph Redmon released a series of 20 lectures on computer vision in September of 2018. As he’s an expert in the field, I wrote a lot of notes while going through his lectures. I am tidying my notes for my own future reference but am posting them on Medium also, in case they’re useful for others.

Joseph Redmon released a series of 20 lectures on computer vision in September (2018). As he is an expert in the field, I wrote a lot of notes while going through his lectures. I am tidying my notes for my own future reference but will post them on Medium also in case these are useful for others.

His first lecture is an introduction in which he details the differences, methods and applications of low, mid, and high level computer vision (CV).

With over 210 million daily active users, Snapchat remains one of the top applications that people use to enjoy augmented reality experiences. The app’s wide variety of AR features lets users do everything, from giving their digital selves some doggie ears to adding realistic 3D effects and transformations.

Snap has always been proactive about letting people come up with new ideas and designs, with Lens Studio allowing developers to “create, publish, and share Lenses” across the platform. To date, Snap reports over 1 million custom Lenses created.

In the previous post in this series on working with forms in React Native, you did a lot of things—from creating Login and Signup forms from scratch, to using powerful libraries like Formik and Yup, to validating those forms.

In this tutorial, let’s extend our knowledge of building and validating forms by handling different input field types other than strings. You’re also going to see my solution for how to gracefully create a Confirm Password field and validate it using the reference of the already set up password field.

Most smartphones come with a sensor of some sort: Gyroscope, accelerometer, ambient light, proximity, GPS, among others. These sensors each have their own functions, ranging from detecting the your phone’s orientation to determining your current position on the globe.

In this tutorial, we’ll take a look at how we can use the phone’s accelerometer to move a ball through a maze. We will be using React Native to create the app. For the accelerometer data, we’ll employ the help of React Native Sensors and build the game with MatterJS and React Native Game Engine.

At WWDC18, Apple announced an exciting new addition to their machine learning frameworks, Create ML. Create ML gives developers an easy way to create custom, lightweight machine learning models within Xcode.

When combined with existing frameworks such as Core ML and Vision, iOS developers (even those without prior knowledge of machine learning) can create apps that use custom models they built themselves.

While TensorFlow Lite is amazing, it has certain shortcomings that surface when you’re trying to run a model containing custom operations that aren’t supported by the framework.

Trying to load and run such a model often results in exceptions similar to the following :

As you can see, the model I was trying to load needed 3 operations (Normalize, ExtractFeatures, and Predict) that were missing from TensorFlow Lite’s default dependency.
