In a bid to deliver immersive virtual reality experience without complicated setup, various vendors have been developing [[Windows Mixed Reality]] compliant headsets. Lenovo Explorer is one of the latest devices to join the fray after being revealed at IFA 2017. Developed by computing giant Lenovo, this virtual reality headset is released for purchase in October 2017 and is priced at $399 for a set of Lenovo explorer headset and a couple of motion controllers.
The '''Lenovo Explorer''' is a [[PC VR]] [[head-mounted display]] developed by [[Lenovo]] as part of [[Microsoft]]'s Windows Mixed Reality platform, announced in August 2017 and released in October 2017 at a price of $349 for the headset alone or $399 with motion controllers. Distinguished by its exceptionally lightweight 380-gram design and convenient flip-up visor allowing instant transitions between VR and reality, the Lenovo Explorer offered 1440 × 1440 per eye resolution with a 110° field of view—the widest among the first-generation Windows Mixed Reality headsets. Featuring dual inside-out tracking cameras for room-scale VR without external sensors, support for 11.5 × 11.5 foot play spaces, and compatibility with Cortana voice commands, the Explorer delivered a compelling balance of features, comfort, and price that made it one of the most popular WMR headsets at launch.


== The Lenovo Explorer Headset ==
== History and Development ==


Built with plastic material and spotting dark grey on black, the Lenovo Explorer only weight 380g making it comfortably light. The headset is worn against the forehead where a strap is fastened just above the top of the neck. At a glance, it bears similarity to [[Oculus Rift]] and [[HTC Vive]]. But what differentiates the Lenovo Explorer headset from its competitor is the ability to flip the visor up, giving the user instant access to the physical world. The headset requires only a USB3.0 and HDMI connection to the PC to function.
=== Windows Mixed Reality Platform ===
Microsoft initiative:
* Late 2017 launch
* Multiple OEM partners
* Inside-out tracking
* Accessible PC VR


The uniqueness of the Lenovo Explorer is the two front-facing camera built into the headset. This is vital in scanning and relaying the wearer’s location for Microsoft’s beaconless tracking technology similar to those used for [[Hololens]]. The headset’s visual came from a couple of 2.9 Inches display with a resolution of 1440 x1440. With a native refresh rate of 90Hz, the headset provides the user with a smooth immersive visual experience. The headset allows user 110 fields of view and is packed with various sensors.
