The main HoloLens 2 menu resembles the desktop of a Windows PC or Android Smart Phone, with buttons for various functions. These include an Internet browser, 3D viewer, photo gallery, settings, tips, remote assistance, guides and your e-mail. There is also a menu on the right that will link to whatever apps you have downloaded.
Accessing these functions is as simple as pushing a button. You may need to step back or forward to get the HoloLens 2 to register the gesture.
