Introduction

Augmented Reality (AR) is an emerging technology that seamlessly blends real world elements with virtual elements in real-time. AR technology has the potential to revolutionize many industries such as gaming, education, entertainment, healthcare and marketing. Machine Learning (ML) is an artificial intelligence technique which enables computers to learn from data and enhance their performance over time. In this article we look at how augmented reality can benefit from machine learning.

Background

Though AR technology has been around for some time, it is only recently that it has become practical. AR works by superimposing virtual objects onto the real world using a camera and display device. These can range from text and images to 3D models and animations. The key challenge in using AR is making these objects appear real even though they are not physically present.

One way to accomplish this is through machine learning (ML). ML algorithms can be employed to analyze the real-world environment and detect objects/surfaces that could serve as anchors for virtual objects. Furthermore, they track camera movement and user position in real-time - essential elements in maintaining the illusion that these virtual objects are part of reality.

Applications of AR in Machine Learning

Machine learning (ML) can provide numerous advantages to AR. Some of the most promising uses of AR in ML include:

Object Recognition

Object recognition is an integral element of AR. Machine learning algorithms (ML algorithms) can be employed to recognize real-world objects and use them as anchors for virtual ones. For instance, an ML algorithm may analyze a room and identify its walls, floor, and ceiling; this information could then be utilized to anchor virtual furniture pieces, decorations or entire rooms within that virtual environment.

Gesture Recognition

Controlling AR with gestures such as waving your hand or nodding your head can be done. Machine Learning algorithms (ML algorithms) can recognize these gestures and interpret them as commands for the AR system; for instance, users can wave their hand to move a virtual object or nod their head to select an option from a menu.

Object Tracking

Object tracking is essential for AR to create the illusion that virtual objects are part of real world. Machine learning algorithms (ML algorithms) can be utilized to track real world objects and surfaces, as well as track the camera and user position. With this data, one can adjust virtual object position, size and orientation in real-time.

Visual Search

Visual search is a technology that enables users to locate products or information by using images. AR can enhance this experience by overlaying relevant information onto real-world objects, while machine learning algorithms recognize these items and retrieve pertinent data from databases. For instance, pointing your phone at a product will give you detailed product info such as its price, reviews, and availability.

Challenges=

Machine learning in AR presents several challenges. Some of the most significant ones include:

Data Quality

ML algorithms rely on high-quality data to learn and enhance their performance over time. In AR, however, the quality of the data may be compromised due to factors like lighting, shadows, and reflections. This could cause inaccurate object recognition and tracking accuracy which ultimately compromises the overall experience.

Latency

AR relies on real-time performance to give the illusion that virtual objects are part of the physical world. Machine learning algorithms (ML algorithms) tend to be computationally intensive, leading to latency issues. Delays in object recognition, tracking and rendering can significantly degrade your experience with AR.

Privacy

AR has the potential to garner a sizable amount of revenue.

Explain Like I'm 5 (ELI5)

Hey there! Have you ever played a game on your phone or tablet where it seems like there are things in the room with you, but are actually just pictures on screen? Like maybe that cute little creature that could interact and move around the room with ease? That's augmented reality - virtual reality as we know it today.

What about augmented reality, which uses computers to augment our vision of the world around us. Using cameras or other sensors, computers can look at our world and add extra elements like cute creatures or helpful information like maps or directions.

How does the computer know what to add to what we see? Machine learning! Machine learning is a special kind of computer program that can learn from its experiences. For example, if we want the computer to show us an adorable creature when we point the camera at a table, we can teach it what a table looks like and then tell it to add that creature whenever it spots one.

Augmented reality and machine learning combine to give us a fresh perspective on things!
