Frequently Asked Questions about Virtual Reality and DFM VR

VR is in everyone's mouth. But the tech behind it can be confusing, as well as what it can brings to you or your company.
Let us help you sort it out with this FAQ.

  • Augmented, mixed or virtual reality... What is the difference ?

    Virtual reality is about virtual worlds that replace the real world, using VR headsets. The real world disappears and you enter a virtual reality.

    Augmented reality is about adding a layer of virtual data to the real world. Tablets and smartphones allow this using the integrated camera, like for Pokemon Go. Devices like the Microsoft Hololens or the Google Glasses also falls into this category.

    Mixed reality often describes experiences mixing real and virtual worlds, as when you merge virtual and real objects to provide feedback. Video where the real player is seen inside the virtual world are also called "mixed reality footages".

    DFM VR provides its expertise in all those fields.

  • Augmented reality or virtual reality then ?

    Tough question. Firstly, it's all about the project and the target. Augmented reality can be the adequate choice for some marketing operation or some small scale projects visualization, when a smartphone or tablet is enough. In the other hand, virtual reality is better when you need full-scale visualization, interaction or immersion.

    Moreover, virtual reality is now mature, with consumer-grade devices, while augmented reality headsets are still only for R&D departments, even if Microsoft, Intel, Meta and Magic Leap are pushing through.

    Down the pipeline, VR and AR will merge into a single wearable device that will be able to do both.

    DFM VR is constantly monitoring the VR & AR field, trying anything new, to be sure to offer the best solution to its clients.

  • There are many VR devices out there. How to pick the right one(s) for my project ?

    There are many VR devices, and more are coming. But VR devices fall into 2 categories : Mobile VR and Desktop VR. If you want more people to experience it, and can deal with some compromises about the experience, go for Mobile VR.

    If you want the premium, most compeling experience and have a showroom for it, go for Desktop VR.

  • What's "Mobile VR" ?

    Mobile VR use a smartphone as the display and processing unit. It holds the phone and allow the user to experience VR without tether, but with some limitations in VR freedom of movement and processing power. Mobile VR consists mostly of 2 devices : Google Cardboard, the cheapest one, and the GearVR, the Samsung x Oculus high-end mobile device. Cardboard can be used with any phone, while the GearVR works only with S6/S7 Galaxy phones, to offer a premium experience.

  • What's "Desktop VR" ?

    Desktop VR uses a beefy computer to allow more compeling experiences, where you can really move into the virtual world, at the expense of a (long) tether. The current devices allowing it to the public are the well known Oculus Rift, and the HTC Vive. Both offer full-freedom of movement in VR, with hand-tracking and a smooth, crisp display. It is currently the most comfortable and compeling way to experience VR.

  • What are the principal differences between the devices ?

    The Google Cardboard uses any smartphone working with the Google Cardboard App. It is also cheap, can be branded, but is the least comfortable and can be quite deceptive on low-end phones.

    The GearVR offers a very compelling experience but, as the Cardboard, does not have positional tracking. Also, it only works with a few phones.

    The Oculus Rift, as the HTC Vive, offers positionnal tracking, 90Hz/2K display, and hand tracking (with Oculus Touch) to interact with the virtual world. The HTC Vive offers a better experience for full room-scale experience.

  • What is positional tracking ? Hand tracking ?

    Positional tracking is currently only provided by Desktop VR. It meens that the user is tracked in space, in 3D, to correctly place him in the virtual space : he can crouch, jump, move in every direction, and do so in VR.

    Hand tracking is provided by additional devices (Vive controllers, Oculus Touche, Leap Motion) to provide the user with virtual hands. It allows to interact with the virtual world.

  • How does DFM VR build VR experiences ?

    DFM VR uses many softwares to build the VR experiences, depending of the target devices and the goal of the project. We use Unity for anything Mobile VR, while we use the Unreal Engine to build our Desktop VR experiences.
