In the eyes of many gamer users, Logitech is a large high-end peripheral manufacturer. This Swiss manufacturer, founded in 1981, is famous for mouse, keyboard, speaker and other peripherals. "Demonstrator, briefing machine, PPT page turning pen, and electronic pointer", which sound lofty, are actually the "remote control" used to turn pages for PPT that we see in classrooms and conference rooms.
The main users of the demonstrator are lecturers/teachers/government and enterprise leaders. This is the most unpopular peripheral in the PC field, and ordinary people are not likely to use it. It's hard to associate Logitech with demonstrators, but in fact, Logitech is the largest manufacturer of demonstrators. The price of the demonstrator is widely spread. You can buy Hanwang's low-end products for more than 30 yuan, which is basically a page turning key plus a laser pen. At the level of more than 100 yuan, there are Taiwan Haoke, Kensingtong, Nuowei, Tagus and other manufacturers, and at the level of more than 100 yuan, there is Logitech.
Previously, the R400 of Logitech R series was the most famous and best selling product of its kind on the earth, and also the most pirated product. It was used by many government agencies and large enterprise offices. It is so brilliant that it even overshadows its replacement product R800 (mainly increases the display screen and countdown, with mute, black screen, volume adjustment and other functions).
The Logitech Spotlight demonstrator we evaluated this time is a completely different series, which is completely different from the previous R400/R800 in terms of appearance style and functional design. It is available in three colors: gold, tile grey and silver. The quotation is also very "Logitech", and it is even on the shelves of Apple Store. The price is 129.95 dollars, equivalent to about 900 yuan. Its Guohang price is 799 yuan, which is higher than the foreign version of Conscience, but still very expensive. Let's see now Look at one of the most expensive presenters on earth.
Appearance and workmanship
Logitech Spotlight is packaged in a white paper box, with a bright green waist seal, and a bilingual product introduction in Chinese and English on the back.
There are three layers of packaging, the top is the machine body and sponge bracket, the middle is a very unique Type-C charging line, and the bottom is the attached leather case and various paper materials.
The leather case is very light and thin. It is similar to litchi leather. The depth is just enough to fit into the machine, and the tightness is also appropriate. The only pity is that the leather case does not have its own handle.
Logitech Spotlight's main body is an elliptical cylinder with fine grit. The body is relatively smooth. The front is a simple 3-button design. The pattern on the key is just as its name implies: pointer, next step, and previous step.
The upper side of the back is a dark black cover plate, At the bottom is simple product information. cover The surface treatment of the plate is very special, a bit like a skin like coating, which will not deform when pressed, and will not leave scratches even if the nail is scratched. Although it will still be scratched by the sundries on the desktop after long use, this black surface is really easy to take care of.
At the bottom of the fuselage is a USB wireless receiver, which has the same working principle and shape as the 2.4GHz receiver commonly used by wireless keyboard and mouse, except that the Logitech Spotlight receiver is equipped with a silicone ring buckle, and the interface has simple product information.
After pulling out the receiver, you can see the Type-C interface used for charging inside, and the receiver slot also serves as the charging slot.
Workmanship and feel
Very "Nordic" workmanship: For a top demonstrator/page turning pen worth 799 yuan, normal people have high expectations for its workmanship. Although the materials and design of Logitech Spotlight are in place, the workmanship is really "IKEA" and "Nordic". The gaps between different parts of the machine body, keys and the machine body are large, which increases the difficulty of dust cleaning. Once water is accidentally spilled on the machine, the gaps are easy to get water.
Magic touch: Logitech Spotlight is similar in size to the remote control of many TV boxes. Because of the built-in lithium battery, it will be slightly heavier than expected and the center of gravity is evenly distributed. The combination of size, shape, material and weight is very "magical". You can't help playing with it when you hold it, and your thumb automatically returns to the key. The next button is made of the same material as the back. It is more comfortable to press and hold it for a long time than to press metal directly. If you want to score this ergonomic design that looks extremely simple but feels magical, it must be close to full score.
Usage&Working Principle
Usage and connection method: Logitech Spotlight, like wireless/bluetooth keyboard and mouse, supports 2.4GHz and bluetooth connection modes. The receiver used by the former is at the bottom of the machine, while the latter needs to connect devices to support bluetooth, but does not need a receiver. Logitech Spotlight does not have instructions in the packaging box. All the tutorials and software are the client itself. Follow the guidance of the software, use USB to charge Logitech Spotlight (there is a hidden white breathing light on the top), connect the receiver to the computer/tablet, or work through Bluetooth connection (Click the "Page turning" button to complete the connection within 1 second) 。
working principle: The name of the wireless pager is very tall, but it is essentially a simple and crude 2.4GHz+Bluetooth "body mouse". The up and down page turning keys map to the left and right direction keys on the keyboard. The more advanced is its own somatosensory remote control function, which generally appears on the TV box or intelligent projection. To describe it simply, it can control the movement of the mouse/screen focus through remote control pointing. Due to the limited principle, its official working distance is 30 meters. In offices with complex wireless environment, the actual distance is about 10 meters.
Client and function
client: This client reminds the author of fitbit, which uses the floating window design mainly in dark gray, supplemented by bright green. The animation and interface design are very cool, window If you lose the mouse focus, it will be automatically hidden 。
The client can set the timer, page turning keys and pointer functions, which is easy to use. Unfortunately, the software only provides a 4-format power indicator, which would be better if there were a common percentage (although this is not meaningful for a device that can run for 3 months with a full charge).
Compatible platform and software : Because of its nature and ordinary Bluetooth/wireless mouse, it can be compatible with almost all platform operating systems, including Windows, Mac, Chrome OS and Android. Around the largest Microsoft Powrpoint (commonly known as PPT), Apple's Keynote, Google's Slide and Prezi, known for their cool animations, can all be compatible with the functions of page flipping and focus magnification.
For PPT demonstration, Logitech Spotlight's default functions include the following:
Kinematic mouse: Built in three-axis acceleration sensor and gyroscope, it is an individual mouse, which can directly control the mouse and execute the left mouse button operation, which is a very rare function in similar products.
Pointer key: While pressing the trigger of the somatosensory control cursor, prompts such as surrounding shadow/magnification/circle will be superimposed on the screen. This is the killer function of Logitech Spotlight, and it is also the biggest difference from the traditional demonstrator;
Next step and return: It is a common way to turn pages up and down in PPT presentations. On Logitech Spotlight, with the client, long press can complete fast forward, white screen, gesture scrolling, volume adjustment, custom key output and other functions.
Screen display timer: By default, 5 minutes before and at the end of the set time, there will be a vibration reminder. The client can also directly float a timing window.
user's experience
Logitech Spotlight's up and down page keys trigger the left and right direction keys by default in the system, and you can move the cursor directly when entering content. Press the pointer key to trigger the somatosensory pointer, and the pointer key itself serves as the left mouse button. It is worth noting that even though No client installation, Logitech Spotlight Page turning up and down and body remote control can be directly effective. Without opening the client, Logitech Spotlight's key response and somatosensory pointer are very sensitive, and it is a competent "mouse".
The biggest function of opening the client is to obtain the focus amplification of pointer keys, as well as the functions of scrolling and key mapping. Click the pointer key, and the surrounding area will be covered with shadow by default. You can select the effect of adding hundreds of circles and enlarging. The size of this circle can also be customized. But when this function is enabled, It is estimated that this is to reduce the jitter of the user pointer, The sensitivity of the somatosensory pointer will become low with a delay of a few tenths of a second. Although it is not unusable, and the effect of pointer stabilization is obvious, the delay is really uncomfortable. Different people have different opinions on this choice, but the author still hopes to have a delay option for users to customize.
Press and hold the button, and move the remote control up and down to directly control the volume
You can scroll the web page with body feeling
As long as the list window can scroll tactically, WeChat can also
The same scroll can be used on the picture to zoom in and out
The author's favorite feature is its customized somatosensory operation function. Long press the button to move Logitech Spotlight up and down, which can adjust the volume and scroll pages on various windows (high-speed page turning in PPT), The effect is good when the decoration is completed invisibly. The sensitivity of rolling is not high, and it is convenient for precise operation, but it may be tired when rolling quickly. What should be noted here is that many flagship products of the same industry use these functions as buttons. This is not unique to Logitech Spotlight, but it is only done in the form of body feeling for the time being.
The only disadvantage of these advanced functions is that they need to be used with clients. Before using, you need to install the corresponding client on the demo device, and also download or transport the USB flash drive. At this time, you will hope that if the official can add the USB flash drive storage function to the USB receiver, the lecturers/teachers can take one less USB flash drive out.
In terms of endurance, Logitech Spotlight has its own The 85mAh lithium battery can be charged for 3 months in normal use scenarios. It can be used for 3 hours after one minute of charging, and it takes 60 minutes to fully charge. The machine will have vibration and red indicator light to remind the user to charge. In daily use, the machine will automatically enter the sleep mode, and will automatically start when picked up with a vibration warning. The most distinctive feature is the ability to charge quickly in one minute. As a productivity tool used by enterprises, it can work normally even if it is temporarily charged for a few minutes during a speech at a conference, which is easier than the common dry battery.
summary
Functionally, there is not much difference between presenters. They are just tools for speakers to control PPT page turning at any time. An app like "PPT remote control" can be installed on the mobile phone to complete this task. The app has more functions than a special demo. However, when actually on stage, the speaker/teacher only needs an entity demonstrator that can be operated blindly and will not drop the link at a critical moment.
In front of ordinary users, Logitech Spotlight may just be a wireless/Bluetooth mouse with shortcut function, which can only be used on smart TV at ordinary times. But it is an enterprise equipment, and it is difficult to measure it according to the standard of consumer electronics. Its design focus is simple, stable and durable. It is more like a trial work with highly simplified appearance and emphasis on functions. Although it has a high degree of completion and a magical feel, it is really expensive. Whether it can defeat its predecessors depends on how everyone votes in RMB.
