Foreword
Some time ago, I once wrote a post:
# Original Innovator # University Green Pepper Purchase Microsoft Microsoft Surface Pro4 Tablet PC Report
# Original Innovator # University Green Pepper Purchase Microsoft Microsoft Surface Pro4 Tablet PC Usage Report At the end of 2015, I worked in a university in the north. Become a green pepper formally. The original use of Macbookpro13 has always been to write papers, check information, enjoying themselves. However, after entering colleges and universities, discovering the mac system, there is no way to match the office environment. For example, IE is used to check wages, OFFICE is used for teachers' multimedia, and the library system is used by Microsoft. My MACBOOKPRO locusts | Likes 24 Comments 59 Favorites 45 View DetailsAs notebooks nowadays have fewer and fewer interfaces, it is believed that USB-C will become popular. In my opinion, this is the correct trend.
The reduction and emptiness of interfaces mean that virtual space is more and more important. Space will serve as a medium for communicating people and things in the future. For example, Bluetooth, wireless charging, retina scan unlocking, VR, AR and so on. Hiding its sophisticated technology in simple human-computer interactions, I am afraid, will deeply affect the way people live in the future.
The ultimate simplicity of technology products confirms Zen thoughts, with less being more and empty being.
The German philosopher Heidegger said that the essence of human existence is annoying. Annoyingly, because too many choices make it impossible for people to choose from, and they have nothing to do with anxiety. This is why people nowadays like the simplicity and exquisite Japanese style and Scandinavian style.
Information redundancy means that human nature is lost.
Reasons to purchaseThe topic reverted back to this article. The colleges and universities where the deaf people are located are lagging in the central and western regions. The campus does not have wireless coverage. The classroom multimedia still stays 10 years ago. The pages are flipped with ordinary demonstrators. Page flipping due to rough work, such as a "for", a "line", a certain one or that, I have already used 7 or 8 bad. All are plastic shells plus a Bluetooth receiver, which gets a lithium battery and gets a small lamp.
If it is said that the rough work has its price and cost considerations, then the following scenario is the common fault of these thousand-year-unchanging PPT pages:
1, can not be timed.In colleges and universities, a class is usually 50 minutes. The schedule is compact. After the bell rings, immediately leave. Because other people in the classroom need to use it, the students have to go to other classes. At this time, they have to go to the most critical moment. Because there is no timing function, the results are gloomy.
2, can not focus.The current page flipping, getting a laser red light, a small green light, etc., is purely redundant. The scope of the instruction was too small. I clearly had to emphasize the passage. As a result, only one point was shot on the screen. The students did not know why. I must emphasize it again. Purely tasteless function.
3, can not use more features.For example, when I spoke in PPT, I found a word that was wrong and needed to be corrected. At this time, I had to withdraw from PPT. The general page flipping couldn't do this, but I could simply go forward and return without ESC exiting this function. bring inconvenience.
I believe that these are the pains of people who often engage in speeches, classes, and propaganda.
The rest, like the unstable Bluetooth connection and the insufficient coverage of the signal, will not be mentioned.
So I had been looking forward to having a presentation pager that could meet the above functions until I saw it:
Logitech Logitech R400 wireless demonstrator price, evaluation, authentic licensed - Logitech official store this goods store.logitech.com.cn direct linkAt first glance, there were favorable reviews, Taobao Jingdong and others had lower prices than the official website, but the goods were sold 10 years ago. They have been sold for a while now. They are a bit stupid and somewhat crude, and their functions are also simple.
Then we see this goods again, or Logitech:
Logitech Logitech R800 professional high-end demonstrator price, evaluation, authentic licensed - Logitech official store this goods store.logitech.com.cn direct linkThe R800, like the R400, has several more features, such as increased timing capabilities, and farther signal coverage. But there is no focus, zoom in, and you can tap more complex menu features. But the overall picture is still silly.
Until Logitech released this in February this year:
Logitech Spotlight Wireless Presentation Pages Logitech Spotlight Wireless Presentation Pages with multi-device support, intuitive controls, and outstanding highlighting give you full control of the presentation material. Direct linkSee the official page introduction, I rely on, the function is a nirvana ah
1, the pointer system.You can zoom in and out and focus on a point in the picture. At the same time, the surrounding picture is darkened. You can also continue to zoom in and out.
2, can play video directly.There is no need for manual operation, and it is not necessary to go to the computer to operate. Previously, video was opened by hyperlinks. After watching the video, return again. Tossing back and forth trouble, if you have a video playback button, hold down the top key, move to the play button, click to play.
3, a wealth of connections, a variety of Bluetooth protocol support.Both through the built-in Bluetooth receiver, but also directly through the Bluetooth connection. What's more, win10 and mac computers take it all together. (But according to my experience, support for win10, there is no mac smooth, experience below)
After reading the official website of the beautiful picture introduction, buy buy buy! Although it sells expensively, it will be nearly 800 oceans.
Then joined the shopping cart and found to be dumbfounded and unable to purchase. Because it cannot be selected.
Consulting official customer service, said that there is no official distribution. The same is true of Jingdong's own business.
An upset. Think well, then wait and wait.
Coincidentally, after a few days, when I was visiting Apple's official website, I suddenly found that the third-party peripherals also added this product, and only the silver-white one (officially there are three colors), I do not know if Match the forcing of apple. The eyeball continues to sweep down and suddenly sees two striking words:
In stock.
Link under:
Logitech Spotlight Demo Remote Control - Apple (China) Logitech Spotlight Demo remote control, will show you efficiently and quickly. Buy it online at apple.com. Direct linkSo immediately called Apple's official customer service, customer service staff on the phone, clearly told me that there is goods. As long as you place an order now, you must come after 3 days.
Buy buy buy!
Three days later, the postal brother was sent on time. Here is the out of the box experience.
Appearance GallerySimple box, as always, corrugated box.
Open up, this embodiment:
Continue to tear down:
Concise, open and slightly scented. There are data lines, very short. Leather case. Instructions and so on.
Together with the leather case, the leather case is not leather, but the texture is good:
Manuals and other accessories:
experience feelingsNext, according to official instructions, plug in the Bluetooth receiver and charge it for a minute. Why do you want to do this? Because Logitech said, charge once and use March. Is there a sense of sight in the slogan of a domestically-made mobile phone in Bad Street?
Logitech officials said that the use of their software will have greater effect. The following is the interface for the first time that I connected spotlight to the surface pro4 with a data cable.
as follows:
The battery life is reversed and there is power management inside. When you don't use it, it will stand still. Will not and now these stupid cap PPT page flip, if you forget to close, then the next class suddenly found no electricity, charging everywhere, everywhere looking for charging line dilemma, will often be staged.
The vibration reminder is as follows:
Next, let's put a little bit of poison. When this demonstrator is charged, the breathing light will flash, which is very beautiful. It is exactly the same as the breathing lamp under the Apple laptop a few years ago. Because there is no way to directly upload videos, Aunt Zhang has to ask Yuki to go out first to get it out.
Because time is tense, it will slowly come to a detailed evaluation in the future, and then make an explanation.
Finally do a little summary.
to sum upLet me talk about the advantages:
1, the button is simple.There are only three. The top button performs functions such as focusing, zooming, and selection. The following are the forward and back buttons. But the following two keys can be held down, can quickly advance and quickly retreat, like the fast forward and backward cool when watching movies, which is very convenient for me who often need to return to the head to find a PPT. save time.
2, vibration reminder function.In 50 minutes of a lesson, if you set a reminder, it will vibrate you at 45 minutes and the time is coming. Of course, this time, you can set it up in the software. This is definitely a big killer. Obviously, this is an improvement to the R800's alert function. Moreover, the vibration reminder is much better than simply making a sound. Do not bother everyone, and at the same time know what to do.
3, focus function, zoom details.When focusing, the surroundings will be darkened and the focus will be enlarged. The students will see at a glance and be intuitive and effective. Save me a lot of spit stars.
4, feel good, amazing life.After buying it, it has been used for more than half a month and electricity is still available. (According to an average of 2 hours per day). More humane is that the lithium battery behind can be removed and replaced. The whole is a little heavier but it has texture.
5, rich features.You can play video directly and direct the entire computer. For example, PPT page, you can perform the exit, and then shut down and other functions. Or you can modify it temporarily.
6, the interface is convenient.The charging cable has a USB-c port at one end and a USB port at one end. The interface is convenient and consistent with the future interface. This is praise.
The next step is insufficient:
1, as always, the price is expensive, it may be gradually cheaper.Poor 2 yuan 800 ocean, really TNN expensive. It will not be long before many domestic cottage manufacturers or a large factory will copy it, and then the market is full of goods or similar goods.
2. The support for MAC system is better than the support for WIN10.The MAC is smoother than the win10 pointer and its movement is smooth. But only slightly different. It may be related to the optimization of the system itself.
3, charging data line is a bit short.However, this is not enough. It's OK to think for yourself.
Because the content of the class is private, I did not take down the specific situation in class, and I will take some pictures in the future to help the valued friends understand the next step.
As a young teacher, it is not easy to prepare a lot of dry mouth every day. The students underneath do not like to listen to it. The mood can be imagined. However, it is very gratifying to see the praise of students.
Write a detailed evaluation later.
Ask for your friends and Aunt Zhang to pay the gold! ! Thank you! !
