The CloudFormation templates you deployed earlier included a rather complex configuration that was assigned to your EC2 instance the moment it connected to the Greengrass service. Let’s take a look at what this consists of as a jumping-off point for further exploration of what these components can do for you. In the AWS Management Console, […]
ContinueAWS IoT Greengrass requires several policies and other constructs to be created in your account before you can attach devices to it. This section will walk you through using a set of AWS CloudFormation templates to automate the creation of these backend components. Recommendation – use Linux or install WSL2 All command-line operations shown are […]
ContinueLet’s zoom in on the specific use case of emergency response. There is no opportunity for first responders to ensure an appropriately designed Wi-Fi network is in place before responding to a call. Cellular connectivity is a must in such circumstances. The Rokid X-Craft is an example of AR glasses that are appropriate for first […]
ContinueAnother way to deliver XR for online gaming is via pixel streaming. This works in much the same way as Virtual Desktop Infrastructure (VDI) solutions such as Amazon Workspaces do: Figure 11.9 – Unity-based shared virtual world using pixel streaming Notice that in the preceding figure, the client/server configuration remains. Each player is assigned their […]
ContinueMR combines aspects of both AR and VR. It not only overlays but also anchors virtual objects to the real world, allowing users to interact with these objects as though they are there. Users can manipulate virtual objects in real time, offering a seamless blend of both realities. Like AR, high-resolution (or outright transparent) passthrough […]
ContinueIn contrast to VR, AR doesn’t shut the real world out – it overlays virtual elements onto it. Through devices such as smartphones, AR glasses, or specialized heads-up displays, users can see and interact with virtual elements that appear to exist within their physical environment. Examples of AR you are probably already familiar with include […]
ContinueThe other half or so of headsets sold now actually have their own CPU and GPU embedded within them. This allows them to run a local operating system (typically Android) for independent operation: Model Name Resolution Refresh FR CPU RAM GPU Connection Price Pico 4 2,160 x 2,160 90 Hz No XR2 G1 8 […]
ContinueIf you haven’t tried a third-generation VR headset, you are missing out. First-time users are invariably impressed with how high-resolution and engaging the virtual world is – it is something that needs to be seen to understand. While it is very difficult to make absolute comparisons between these devices due to the dozens of differences […]
ContinueVR immerses users in a completely simulated environment, shutting out the real world completely. This allows users to experience a completely different reality through purpose-built VR interface equipment such as that shown in the following figure: Figure 11.1 – The author building a VR application with an Oculus Quest 2 headset Of course, VR is […]
ContinueThe ability to deliver high-quality immersive experiences has become a more common expectation across various domains, ranging from gaming and entertainment to professional training and simulation. As the technology underlying these experiences enters its third generation, user demand is rapidly increasing. These applications demand a cohesive integration of visual, auditory, and interactive elements to simulate […]
