Knowing that Unreal Engine 4 works with the vast majority of VR technology, our next step is to choose the type of VR headset we would like to use. There are many factors that can contribute to this decision. The first is knowing who the target audience for our experience will be. Start by researching previous games that are similar to our design. By doing so, we can find out what segment of gamers will purchase our style of game and see whether we can interview a few players who fit this demographic. With this information, we can make informed design decisions as we go through the process of development, which will result in a game that really appeals to its player base.

The next factor we need to be aware of is what type of experience our design is most suited for. VR experiences fall into a few distinct categories:

• Room-scale VR
• Seated VR
• Mobile VR

The first is room-scale experiences.

These are active experiences that require the player to move, jump, and perform actions inside a predetermined area covered by sensors. An example of the room scale pay space covered by the lighthouse sensors that come with HTC Vive is as follows:

For experiences that may not require that particular level of activity, there are seated VR experiences. An example of the space needed for a seated-or standing-only VR experience is as follows:

Seated experiences are built around the idea that the player remains stationary and that only the headset's orientation data is needed.

Finally, there are mobile experiences. These experiences are formatted specifically for mobile devices, such as the Samsung Gear VR and the Oculus Go. The original version can be found on the following link: https://commons.wikimedia.org/wiki/File:Samsung_Gear_VR_Experience_(16241072054).jpg.

Mobile experiences are designed to take advantage of the accelerator and gyroscope found in smartphones to provide an immersive experience and to control gameplay. For our game, we will likely have the player stand in a small area with their tools for the task close at hand, though some movement may be required. With this in mind, we will design Server 17 to be a room-scale experience.
