Future challenges of VR VR面临的挑战

覃金芳

盡管VR技术给我们的生活带来诸多益处，但也有些挑战需要我们去面对，如设备创新、价格过于昂贵等。总之，VR技术还有很大的提升空间。

Being a relatively new technology， VR technology is clearly just beginning to take off. There are companies producing their own VR headsets， but they are still not as big as other products that are meant to entertain. Apart from the limited options， one more thing that is worth noting about the current state of VR is the fact that content is limited， as well as the applications. Most of the products available on the market today are targeted at gamers and mostly exclusive to high-end buyers because of its expensive price.

In spite of being full of potential， however， there are also some challenges that should be addressed in order to ensure the success of VR. Among others， one of the most significant would be the need for powerful devices that would complement the headsets. For Oculus Rift， for instance， a powerful video card is needed for a computer， something you might not have at home， making the VR technology inapplicable.

In addition， there are also challenges when it comes to beauty. Todays VR headsets look almost entirely the same—they are bulky， and they look silly. Manufacturers must find a way in order to make the design more beautiful.

Manufacturers will also be challenged to make VR headsets more affordable so that more people will be able to purchase them. Most of the models currently available are just too expensive for average buyers.

Lastly， and perhaps most importantly， the challenge is to find more applications. It is currently being centered on game-based app-lications. Manufacturers are challenged to come up with creative ways in order to increase the usefulness of such a promising device.

In sum， while it is undeniable that VR is big in todays time， there is a lot of room for improvement. There are limited choices when it comes to VR products available on the market， and for many， it is still a bit expensive. Others lack knowledge on how it works， which results in hesitation. There are also some obstacles that have yet to be handled and more opportunities to be uncovered. It would be safe to say that it is still in its infancy， but hopefully， it is getting to the top.
