The developer version of Google Glass has already been shipped, and a reporter from Sina Tech in the U.S. also got a pair to try out. Having used it for less than a day, just testing the basic functions, they have shared some initial impressions:1. Where can you buy it?According to Google, the official consumer version will be available next year. The current few thousand units are only available to participants who pre-ordered at last year's Google I/O conference and online applicants, who must have a U.S. address.Priced at $1500 before tax (approximately 9300 RMB), it comes in five colors: red, white, blue, black, and gray. Google does not allow current users to transfer ownership of the glasses.Google Glass may not be officially launched in China. If domestic friends really want to buy it, they can wait until it is released in the U.S. next year and then look for it on Taobao or through a proxy purchase.2. Is it comfortable to wear?From feedback from people who have already tried it in the U.S., they all say that Google Glass is lightweight and comfortable. However, after wearing it for an hour myself, I experienced issues with it pinching my forehead, and when the nose pad slid down, I could no longer see the display clearly.This might be because the current design is based on European and American face shapes, which tend to be narrower with higher noses, making it fit perfectly for them. If you're someone like me, with a larger face and a flatter nose, typical of Asians, it might affect your experience. Hopefully, it's just bad luck on my part.3. What if you're nearsighted?Currently, there is only a regular version, with sunglasses lenses and transparent lenses. Nearsighted users can only wear contact lenses or undergo surgery (which isn't worth it).A nearsighted version of Google Glass has not yet been released, but you can wait patiently. It's rumored that due to technical complexity, it might be a bit more expensive.4. How safe is it?The display is located slightly above the right eye's field of view. The right eye needs to focus upward to see clearly. When both eyes are looking forward normally, the screen appears as a small spot of light and quickly goes into standby mode. Looking at the screen for that moment does indeed distract, and Google advises being more attentive while driving. The bone conduction headphones are also designed to avoid distracting the user.5. Will it affect vision?This is a brand new product, currently only used by Google internal staff and a very small number of pre-orderers. There have been no reports yet on how Google Glass affects vision. I believe that Google would have considered this factor during development. In practical use, if your dominant eye is the right one, you'll get used to it; if it's the left, switching between the two eyes can cause dizziness. I'm unsure if Google will release a left-eye version.6. How do you take pictures?You can control Google Glass by voice command, saying "take a picture," or you can lightly touch the quick-shoot button on the right side of the frame, and the glasses will immediately take a photo without any composition time. The actual image quality is slightly lower than the human eye's effective field of view. To capture what you see, it's best to tilt your head up a little.Videos default to 10 seconds but can also record longer videos. However, the CPU part on the right side will heat up noticeably. It won't burn you, but it's uncomfortable.7. Do you need a network connection?To fully utilize Google Glass, you need a Wi-Fi connection and an Android phone with the MyGlass app installed. Either connect to an external network, use your phone as a hotspot, or use a wireless network card. By generating a QR code through the MyGlass app on your Android phone, the glasses will automatically recognize and connect to the network. Without a network, the glasses cannot perform searches or navigation, but taking photos and making calls via Bluetooth connection to your phone is still possible.8. Can it be used domestically?This is somewhat complicated. Google Glass is deeply integrated with Google Search, Google+, Google Maps Navigation, Google Now for life services, and Google Cloud Services. If domestic users cannot smoothly access Google services, many functions will be significantly reduced, and Google Now will be unusable at the very least. Ideally, you should use a proxy server, but hardware functions like taking photos and recording videos can still be used. Data will be stored within the Google Glass and uploaded to Google+ when you return home.9. Can you share pictures to Weibo or WeChat?Currently, photos are uploaded to a private album on Google+, visible only to the user. Users can also choose to share images and videos with friends on Google+. Path and other third-party apps are already developing features based on Google Glass. If Google Glass enters the domestic market and Weibo and WeChat develop related services, it is technically feasible.By the way, Google has recently applied for a new patent for Google Glass. From leaked patent diagrams, this smart glass is equipped with two lenses, with an appearance very similar to ordinary glasses.The patent shows that the new Google Glass will use a special diffraction grating technology to ensure that users can see the content on Google Glass without affecting their ability to see surrounding objects.We know that the first generation of Google Glass will not be available until next year at the earliest, and this normally styled second-generation smart glass will take even longer.Personal life assistant, yet ads pop up on the screen, even when going to the bathroom. These speculations are not unfounded. After reading this, do you still want Google Glass?
