你是否还记得，在不久前VR还只是一个让人赞赏的好主意。但是突然间它就变成了现实。甚至是在2016年带有数十亿美元发展潜能的手机市场中。如果你是一个期待着创造VR体验的手机游戏开发者，现在便是你开始考虑面向VR头盔创造游戏的绝佳时机。尽管现在的VR头盔不像手机设备那么多，但这第一波头盔的出现也足以让你行动起来了。

帮助你开始的5大建议

性能和优化从来没有这么重要过。游戏屏幕与脸部距离的区别（即离脸有1,2英尺距离vs贴在脸上）就和老电视与全新的超高清4K电视间的区别一样。这是一种巨大的改变。你必须让你的游戏能够更有效地运行于VR上。专注于性能与优化并提高帧率能够帮助开发者降低糟糕的视觉保真度风险，并避免破坏用户体验和行动。

了解每种手机VR头盔的功能。如今越来越多手机游戏开发者和一些VR头盔制造商都加入了这场竞争中。像Google Cardboard，Samsung Gear VR，View-Master VR viewer，I AM Cardboard和Knox Labs都是一些现有的手机VR头盔，并且它们都拥有在手机上传递VR体验的方法。例如View-Master viewer和Google Cardboard虽然都依赖于触屏控制，但是View-Master使用了物理杠杆去碰触屏幕而Google Cardboard则使用了磁铁去模拟“触碰”。这两种控制系统的区别对于用户体验也具有很大的影响。所以手机游戏开发者必须了解所有的这些区别并判断哪种控制系统最适合自己的游戏体验。

拥有高像素密度的屏幕的优势是无可厚非的。而带有高像素密度的手机便能够传递更高质量的手机VR游戏体验。大多数手机VR头盔使用了放大镜让玩家专注于手机屏幕。这有可能导致一些特定设备屏幕上的镜头会扭曲了图像，而高像素密度的屏幕便能够有效解决这种问题。如今市场上有许多Android手机能够满足这些需求（游戏邦注：如Samsung Galaxy line），当然了还有大受欢迎的基于Retina显示器的苹果iPhone。

许多手机VR头盔是通过磁铁去模拟设备触碰感。但是市场上不同手机设备的不同屏幕规格与触碰敏感度都说明磁铁并非适合所有设备。而这可能导致用户不断轻敲设备，重新连接头盔或郁闷地敲打头盔上的按键。而所有的这些行为都只会导致磁铁的失效，即进一步引申出头盔的无效。

手机VR是一种并不昂贵但却超级有趣的体验！而手机VR游戏体验的魅力也拥有继续延伸下去的理由。这是一种有趣，具有沉浸感且不断发展的游戏体验，并且非常适合手机设备。一开始手机VR头盔的售价只有10美元或20美元。这种易用性便意味着几乎所有手机用户都能够拥有它！而对于游戏开发者来说，手机VR游戏是测试VR的一种廉价方式，并且这也能为他们的游戏设计增添一些全新元素。

Mobile VR 101 – 5 Tips to Get Started

by Alan Haugen

Remember when VR was just a cool idea? Then all of a sudden, it’s an explosive reality. It’s even on mobile with anticipated billion dollar market potential in 2016. If you are a mobile game developer excited about the possibility of creating VR experiences, now is the perfect time to start thinking about making games for mobile VR headsets. While there aren’t as many mobile VR headsets as there are mobile devices (yet), this first wave of headsets is more than enough to get your head around (no pun intended).

5 Tips to Get Started

Performance and optimization have never been more important. The difference between a game screen held one or two feet from your face vs. attached to your face is like the difference between an old tube television and one of the new Ultra HD 4K television. It’s huge. Games simply need to run better in VR. Focusing on performance and optimization and maximizing frame rate will help mitigate the risk of perceived poor visual fidelity, unsatisfying user experience and even motion sickness.

Learn about the features of each of the mobile VR headsets. More and more mobile game developers, as well as several VR headset manufacturers, are jumping into the fray. Google Cardboard, Samsung Gear VR, the View-Master VR viewer, I AM Cardboard, and Knox Labs are just a few of the mobile VR headsets out there, each with their own design approach to delivering a VR experience on mobile. For example, both the View-Master viewer and Google Cardboard rely on the touch screen, however; View-Master uses a physical lever to touch the screen and Google Cardboard uses magnets in close proximity to the screen to simulate “touch”. The difference between those two control systems can have a significant impact on user experience. Mobile game developers should get to know all of them and determine which best supports the type of experience they want to deliver.

The advantages of a high pixel density screen are indisputable. Phones with pixel densities are very advantageous to delivering a quality mobile VR gaming experience. Most mobile VR headsets use magnifying glasses to help enhance and focus the phone screen. This can result in some lenses simply distorting the image on certain device screens so a high pixel density screen makes a huge difference. There are many Android phones on the market that meet these requirements (ie: The Samsung Galaxy line) and of course the ever popular Apple iPhones with Retina displays.

Little magnets get lost. Many mobile VR headsets rely on magnets that are built into them to simulate pressing on the device screen. The variations in screen size and touch sensitivities across the many mobile devices on the market can result in magnets not registering for all devices. This leaves the user tapping the device, re-inserting the device into the headset or having to apply lots of pressure to the headset buttons. Unfortunately, this can all lead to losing magnets, rendering the headset useless.

Mobile VR is inexpensive and super fun! The fascination with mobile VR gaming continues and for good reason. It’s an interesting, evolving and extremely immersive game experience and it’s available on your mobile device. Mobile VR headsets start at just $10 or $20. This level of accessibility means every mobile consumer can live the dream! For game developers, mobile VR games are an inexpensive way to test the VR waters, adding a new element to their game designs.(source:gamasutra)
