The HD4000 is a new Enterprise grade, monocular, see through Head Mounted Display. It is a USB-tethered accessory for designated current and future Zebra mobile terminals and is the first product in a new category for Zebra. It provides the ability to boost task efficiency and accuracy by overlaying the most relevant contextual information over the workers’ real-time field of view, enabling hands and eyes to be free to focus on tasks — instead of interacting with an application on a mobile computer to obtain the same data.
