如何从 Android 设备输出到监视器
我正在尝试在 Android 设备上进行演示，但屏幕太小，因此很难在 12 人的会议室中进行演示。尽管我可以在桌子周围传递设备，或者只是简单地借用或获取更多设备用于演示目的。
我知道有些设备可以购买特殊的 USB 转换器来进行电视输出，就像在 iPhone 中一样，还有一些 Android 上的特定设备（例如 Motorola Incredible？），但我必须在运行标准 Android 版本的特定设备上进行演示。
我知道我可以在 Android 模拟器上执行此操作，但屏幕刷新率太慢，因为它会向观众发送应用程序速度慢的错误消息。 （或者有办法提高模拟器的屏幕刷新率吗？）此外，模拟器不支持多点触控。 （还是我错了？）
不确定是否有人
I am trying to do a demo on a android device, but the screen is too small so is kinda hard to do a demo let say in a meeting room with 12 people. Although I can pass the device around the table or just simple borrow or get more devices for the demo purposes.
I understand there are devies where you can buy special USB converter to do TV-out like in iPhone, and some specific devices on Android (e.g. Motorola Incredible?) But I have to demo on a specific device where it runs standard Android build.
I understand I can do it on Android emulator but the screen refresh rate is too slow, as it will send the wrong message to the audience that the app is slow. (Or there is a way to increase the screen refresh rate for emulator?) Furthermore the emulator doesn't support multitouch. (Or am I wrong?)
Not sure if anyone

你没有太多选择。
您可以使用 Droid@Screen，但其刷新率可能为 6fps。我不知道还有比这更快的其他软件投影仪。
您没有提及您正在使用的“特定设备”，因此我无法评论它是否具有电视输出功能。 HTC DROID Incredible 和 Samsung Galaxy S 系列支持复合输出 - 我经常使用 DROID Incredible 来实现此目的。大多数具有 HDMI 输出的设备仅支持某些内置应用程序，例如视频播放器。
您可以租用或购买设备投影仪，例如 ELMO。这些都是相当昂贵的新设备，尽管我在 eBay 上看到一些二手设备的价格很有趣（不过要注意——许多设备似乎缺少交流适配器）。
如果您可以将演示推迟几个月，您也许可以使用 Google TV。
就这样，据我所知。
买一台更快的电脑。
我不知道用模拟器模拟多点触控的方法，尽管我还没有在那里寻找解决方案。
You do not have many options.
You can use Droid@Screen, but the refresh rate on it is maybe 6fps. I am not aware of any other software projector that is faster.
You failed to mention the "specific device" that you are using, so I cannot comment on whether it has TV-out capability. The HTC DROID Incredible and the Samsung Galaxy S series support composite output -- I use the DROID Incredible for this purpose a fair bit. Most of the devices that have HDMI output only support it for certain built-in apps, such as the video player.
You can rent or purchase a device projector, like an ELMO. These are fairly expensive pieces of equipment purchased new, though I see a handful of used ones on eBay at interesting prices (though watch out -- many seem to lack the AC adapter).
If you can delay the demo several months, you may be able to use a Google TV.
And that's about it, AFAIK.
Get a faster computer.
I am not aware of a way to simulate multitouch with an emulator, though I have not gone looking for a solution there.
如果您有 Galaxy S3 Android 手机，则可以使用 Mobizen。免费，屏幕刷新率也比较好。您可以使用鼠标和键盘从计算机控制手机。它使用 USB、3G 或 Wifi 连接进行工作。
If you have an Galaxy S3 Android mobile phone, you can use Mobizen. It's free and the screen refresh rate is relatively good. You can control you mobile phone from you computer using your mouse and your keyboard. It's working using USB, 3G or Wifi connection.
我使用过这个Android截屏工具：http://code.google.com/p/androidscreencast/ 在过去的演示中，但同样的缺点是刷新率相对较慢。
I have used this Android screencast tool: http://code.google.com/p/androidscreencast/ in past demos, but again the downside is the relatively slow refresh rate.
如果您有 root 设备，您可以尝试 Droid VNC Server（市场上有）。刷新率还不错，但我当然不想在上面演示全动态视频或街机游戏。
您还可以买一个网络摄像头，用三脚架架起来。像这个之类的东西。缺点是你的手会妨碍，可能是照明和/或焦点问题。优点是刷新率不错。
If you have a rooted device, you could try Droid VNC Server (it's on the market). The refresh rate isn't too bad, but I certainly wouldn't want to demo full motion video or an arcade game on it.
You could also get a webcam, rig it up with a tripod. Something like this. Downside is your hands will be in the way, maybe issues with lighting and/or focus. Upside is a decent refresh rate.
