The HoloLens is easy to use, but you need to know a few things about how to wear it. In this lesson, learn how to make sure you get the best experience.
- To get the best kind of experience, you need to put on the HoloLens in the most comfortable way. As you can see, the device has an adjustable headstrap. By turning this knob, you can make it bigger or smaller. The headstrap can be moved up and down as well. He best way to wear the device is by having the band go up pretty high on your head. This way the weight presses down on your forehead so you do not have to tighten the band that much, that might get pretty uncomfortable after a while. So put it on like this, and make sure it feels good.
Remember, you will move about wearing this so it needs to be tight enough to make sure it doesn't fall. Once you've tightened it enough, you can tilt the device down. If you wear glasses, like I do, you can pull the visor forward as well, and then move it in front of your glasses, like this. Make sure you're looking through the bottom part of the visor. We showed you earlier where the actual display bar is, you need to have that in front of your eyes.
And that's it. This is the best way to wear it. Next, we need to talk about the gestures that HoloLens supports. There are only two of those, bloom, and air tap, or tap. Bloom looks like this, it's just like a flower opening up. Bloom is what pulls up the main menu, or what gets you out of a running app. The other gesture is the tap. Make a C shape with your fingers like this. Make sure the rest of your fingers are closed. Now make a pinch-like movement, like this.
This is the tap. Tapping is just like a mouse click, you can use it to select objects, or interact with them. There are a couple of variations on this. Tap and hold, like this, and tap and move, like this. Now the HoloLens also includes the clicker, which is a Bluetooth device that lets you tap without holding up your hand. And this is all the gestures we've got.
Join instructors Dennis Vroegop and James Ashley for this introduction for HoloLens app development. They show you how to set up your development environment, including Unity and the HoloToolkit; how to deploy to HoloLens and the HoloLens emulator; and how to build apps that accept user input via gazes, tapping, and speech. Then discover how to use spatial mapping to detect your surroundings and analyze your environment with spatial understanding. Learn how to implement spatial sound that adds to the user's existing environment, and synchronize data to create shared experiences. Along the way, learn how it all comes together in two simple 3D apps: a visualization for enterprise business and a platform game.
