XMG recently unveiled the XMG WALKER at IFA. It is the first commercially available backpack PC specifically designed to meet the needs of virtual reality.
The HTC Vive is the most advanced VR headset on the market. It gives its users the possibility to move in a space of up to 5×5 meters. Until now the Vive requires a hardwired cable connection to a PC or laptop, which limits the user in several ways. The length of the cable, awareness that the user is tethered to a external device, tripping danger and possible damage to the connected PC/laptop are just some of the factors which limit the fully imersive virtual experience that the Vive is capable of delivering.
The XMG WALKER is a revolution in the VR experience. It can be worn comfortably on your back and it allows the user to fully immerse themselves in the virtual experience. The XMG Walker also opens up a multitude of new experiences, for example when used in open tracking arenas not limited to 5x5m, multiplayer VR games, for professional use in demonstrations and in applications that require greater freedom of movement. The XMG Walker not only multiplies the VR experience for existing applications but allows developers to realise the potential of expansive virtual reality environments.
The XMG WALKER weighs only 3.8 kg and is housed in a bespoke, ergonimic and slim solution. Since virtual reality requires high system and graphic performance XMG relies on technology that is also found in XMG high-end gaming notebooks. The NVIDIA GeForce GTX 1070 GPU, supported by an Intel Core i7-6700HQ CPU, far exceeds the NVIDIA ‘GeForce GTX VR Ready” hardware standard.
The XMG WALKER is equipped with two 99.36Wh batteries. Two additional batteries are also included with each XMG WALKER. Two batteries are required to provide maximum performance, however their hot-swappable feature enables an uninterrupted VR experience. A pair of batteries will power the XMG Walker for a minimum of 40 minutes and a maximum of 60 minutes. If required, the XMG Walker can also be powered by a standard notebook power adapter and used as a powerful desktop pc. The XMG Walker includes support for 32GB DDR4 memory, PCIe x4 M.2 SSD, USB 3.0, USB 3.1 Gen2 Type-C, HDMI, DisplayPort, Gigabit LAN and 802.11AC WiFi.
Transmission of the data signal to the HTC Vive via wireless is possible, but only provides poor image quality and leads to delays which cause discomfort and nausea. There is currently no appropriate wireless solution nor is one expected in the near future. Furthermore, the necessary 7 Gbit /s transmission speed can be achieved only in theory. In practice, this bandwidth cannot be provided by the wireless solutions available today.
