Some basic thoughts on online healthcare

The only online medical app I've ever used is "Dr. Chunyu", a very popular online medical app in China a few years ago, where I consulted a doctor for a skin problem when I was in high school and the consultation fee was 8 RMB, or about 1.61 RMB. The doctor I consulted claimed to be from the dermatology department of a state-owned hospital in a city. He reviewed the pictures I uploaded and told me to follow his breeze to buy medicine. In fact, the medicine he recommended had strong side effects and was not effective in curing my condition, but it did help me in a short period of time. In recent years, the reputation of "Dr. Chunyu" app has been declining year by year, and the reasons are complicated. The medical system in China is divided into public and private hospitals. Due to the lack of medical resources and market regulation, private hospitals often have serious problems such as over-medication and medical malpractice. After the popularity of "Dr. Chunyu" APP, for whatever purpose, it began to cooperate with a large number of private hospitals. There may be advertising and other interests involved. Due to the lack of clinical experience and medical qualifications of doctors in private hospitals, users often complain that the medical advice provided by the app does not solve the problem and often directs consumers to local partner private hospitals. This led to a serious decline in the reputation of the app. Dr. Chunyu's market share was further undermined by the introduction of Ali Health, a medical app owned by Chinese Internet giant Alibaba. I downloaded Ali Health, and I found out that Ali Health offers vaccination appointments for all types of vaccines and 30-minute delivery of local medications." Alihealth is more often partnered with large state-owned hospitals to provide online appointments and other services, which is indeed better than Dr. Chunyu in terms of reputation and service experience, but I have not actually experienced it, so I can't comment more. I think there is a huge market for online medical services in areas where medical resources are scarce, such as Ottawa. I have personally experienced waiting overnight in an Ottawa hospital. For foreigners who don't have a health card, don't know how to make an appointment, and don't have a private doctor to help them, the only way to see a doctor is to do the basic walk in. In fact, for many basic illnesses, online Q&A can often solve more than 70% of the problems, and it can take a lot of pressure off the local hospitals. In my opinion, online medical care must be clear about its position, dedicated to solving simple medical consultations, for systemic and serious diseases, it is still necessary to go to the hospital.

It's the only mobile game I still play, even though it's from a small game studio and lacks maintenance and updates. It's a lot like Minecraft, it's graphics look more comfortable than Minecraft and it's smoother to play. I like this open world game better, it has unlimited content to play with, and it's a great way to pass the time. Personally, I think it's rare to get an immersive experience from a mobile game, and the size and performance of mobile devices dictate this limitation, but similar rest games are still perfect for mobile. As for those 3D masterpieces, just leave them to PC or XBOX.

Personally, I think iMovie is the best software for beginners to get started with editing. It is extremely powerful, from inserting audio, getting started with audio processing, video transitions, getting started with color grading and filters, etc. The first time I tried iMovie was to edit a set of aerial videos of Toronto at night on my iPad. iMovie is also suitable for newbies because it requires less hardware and supports more forgiving video processing. I used iMovie for introductory editing and splicing of clips. iMovie has many built-in transitions and customizable settings. I simply dragged the transitions into the timeline, set the duration of the transitions, and got the cinematic effect as shown in the video. Although iMovie doesn't support higher bitrate D-log format, for some advanced bitrate videos, such as DJI Cinelike format which has higher tolerance than MP4 format, iMovie's built-in color grading function can greatly improve the picture effect. However, I did not use this function in the video because it was a night shot.

This is the DJI action 2 sports camera I just purchased yesterday. I would call this purchase a "courageous experience". In fact, I had already read the review of this product before I bought it, and had some understanding of its product features. But to be honest, I couldn't tell which reviews were objective and which were advertisements. So I decided to buy it myself. Indeed, this is a revolutionary camera. Its design and experience completely subvert the traditional sports cameras (such as the gopro series). The product is very small and delicate, with an innovative modular magnetic design. Different modules can be attached according to different use scenarios. It is originally equipped with a wearable necklace, through which the camera can be attached to the clothes on the chest, ideal for first-view photography. It also supports horizon electronic stabilization, no matter how much movement, the picture can always be kept level, and the video specifications supported are quite rich. The above sounds very much like an advertisement, but in fact this revolutionary innovation has a fatal flaw. That is the heat control as well as the range! The overly small and compact design causes the temperature to quickly become uncontrollable during video recording. In actual use, it has repeatedly been forced to shut down due to overheating. And the body temperature can not be controlled will certainly lead to the collapse of life, coupled with the already small battery, the camera in actual use, the power can only maintain about 1 hour of continuous recording. In addition, the charging speed is very slow, making the actual experience very poor. I greatly admire the innovative spirit of DJI as a technology company. This can be the price of innovation, as almost all of its company's products are hardly perfect and always have various drawbacks. There are costs associated with the innovation process, and these costs are paid for by thousands of consumers. Putting immature products on the market to drain the enthusiasm of consumers is a marketing approach that deserves some thought.

Video By 51drones (Tiktok)

This is by far the more interesting video I've seen in tiktok today. A review of DJI's newly released mavic 3 drone. Interestingly enough I saw the same content posted by different people in the Chinese version of TIKTOK...... There may be copyright issues here. The point that makes me feel comfortable is that the review video is about 1 minute long, although there may be a video length limit in tiktok, the same review video on YouTube will be inserted with about 15-20 seconds of ads, which is really annoying, but I didn't find this problem in tiktok. Of course, there are limitations. As far as I understand, tiktiok does not support uploading videos in HD, and videos with particularly large file content will be compressed in quality. This may be a choice that tiktiok's operators are forced to make to take into account the smoothness of browsing on short video platforms.

With regard to Benjamin's account of the "halo" of artwork, there is a subtle shift in my perspective from the first time I read this article a few months ago to the time I read it again today. Today I am more in agreement with Benjamin's view because the aura of the artwork Benjamin describes comes from its uniqueness and its history, its unique existence in time and space, its projection of the traces of a particular era. Mechanically reproduced artworks, on the other hand, lack the baptism and sedimentation of age. However, digital images created on cell phones have a sense of "halo". The cell phone is just a way or a tool, and people use it today to record things in much the same way that people used to paint hundreds of years ago. Both reflect the identity of an era, and digital images are unique in that they can be defined as works of art. Berger's argument that art images have no value is a bit too absolute. berger's artwork has value because of its uniqueness, and the advent of the camera has destroyed that uniqueness, thus splitting its original value. However, the definition of authenticity is complex, the original physical image is more authentic and enjoys its "aura" as a first-hand source, but as I mentioned earlier, digital images are sometimes used as a means of communication only, and it does not affect the authenticity of the artwork. To measure artwork by its so-called value is itself a stain on art.

About VR, AR and 360, I know the most about AR technology, which is also the most practical technology in my opinion at present. First of all, most of the VR technology I know so far is used in the entertainment field, such as the VR-themed entertainment experience pavilions that are everywhere in China. The only time I have applied VR technology to the real world is when I purchased VR flight glasses for my drone, but the actual experience of using them was very bad. First of all, with the current level of technology, it is difficult to connect VR glasses to a high speed flying drone without signal delay, and secondly, since VR causes strong 3D vertigo problem, it is still impossible to overcome this problem with the current technology. I used VR glasses for aerial photography in the process of the 3D vertigo problem, which led me to take off the VR device, and the consequence was that my drone almost collided with a tree. As for 360 technology, it can do a great scene experience and restore the effect, the combination of VR and 360 technology may be able to carry out a vivid online real-life travel. But still, my knowledge of this technology is still only in the entertainment aspect, almost no understanding of its practical functions. On the contrary, AR, this function has been applied in many map navigation software, and even the newly launched vehicles of Mercedes-Benz are equipped with VR real-world navigation function. I've used the AR real-life navigation function of Gaode Map in China, and it works very well indeed. Especially in some complicated road sections, AR Live View Navigation can clearly instruct drivers which lane to take which off-ramp. Some popular games such as Pokémon Go are also based on AR technology and are a big success. I personally think VR is a more promising technology than AR, but VR technology still needs to improve its shortcomings through innovation. In addition, I think AR can be perfectly suitable for cell phones as a platform. But VR and 360 are difficult to play its characteristics because the limitation of the size of the device makes it difficult to do the immersive effect. And real and vivid are the characteristics of VR and 360.

Whether you accept it or not, the phenomenon of digital migration has become a trend. In my country, digital teaching has become a model that schools at all levels are scrambling to experiment with, and although in practical terms its effectiveness is extremely limited, it seems to be becoming a popular attempt at what we call intelligent teaching. I once saw in an official Chinese media promo a leader inspecting an elementary school, and instead of books, all the elementary students had tablets on their desks! Anyone familiar with the Chinese media knows that the official media has less credibility and this kind of coverage is mainly used for propaganda. But it actually sends a signal that China is experimenting with intelligent, digital, paperless teaching.

Personally, I believe that the new generation now and the generation to come are born digital natives. I didn't have my first cell phone until I was in high school, and my 2-year-old brother is already proficient in using multiple functions on his smartphone! Digital immigrants are a product of their time. Some articles critically analyze the digital age, and I don't think there's anything wrong with that, but no matter how you analyze it, it's already a fait accompli. To be honest I define myself as a digital immigrant because while I think critically about digital I also can't seem to live without it anymore. But I believe that no matter how society progresses, the controversy over the ethics and morality of technology and other aspects will never stop.

This article poignantly points out the flaws in the current mobileization of major vendors' products and services. Some of the most important qualities of the product itself, such as user experience and usability, are ignored in order to achieve mobile. I get the impression that there are some mobile product services currently being released just for example to fill the gap in their mobile market. One example I just experienced was the inclusion of a new mobile payment method in our university's library parking lot. But that app experience was extremely perplexing, with the need to top up before using it, rather than selecting a time and then charging the credit card directly. This secondary operation often takes longer than the time spent at the payment machine, and furthermore, the user experience is extremely poor as they do not receive an alert when their parking ticket is about to expire. Mobile strategy requires care and detail. Apple and Tesla are two companies that have succeeded because of their careful consideration of optimizing the experience of using their products. Tesla's car will often push ota upgrade, each time is basically to optimize the details to achieve a better user experience, this "craftsman" spirit is worth some companies are in the process of mobile strategy or has been carried out to learn.

To be honest, recent generations of iphones have not had any substantial innovation. There is nothing to make people want to buy new phones. In recent years, the main product enhancements in addition to processor updates iterations, the rest of the updates are in the camera. But the phone is a phone after all, its size and cost is limited. I don't understand whether Apple has great confidence in its user loyalty or whether it thinks the Android camp lacks competitive products. iphone13 has made some upgrades in terms of user experience, but I wouldn't call them innovations. Because the phone movie mode and with 120hz adaptive refresh rate screen in some Android brands have been implemented. What disappoints me is that I thought the under-screen fingerprint recognition technology would be applied to the iphone13, but it is not. In the context of covid normalization, masks are the biggest resistance to face recognition. And the under-screen fingerprint technology can greatly enhance the user experience without affecting the design of the phone. Moreover, the technology is not new nor complicated. It is really impossible to understand why Apple does not apply this feature.

What is innovation? Anything that changes the way people work, live, or think is called innovation. Innovation may exist in a very subtle way. The success of Starbucks, for example, is not the variety of drinks it offers, but the new consumer experience it provides - a public meeting space for customers to relax. Starbucks' business innovation has changed the way people think about innovation and the way some people live their lives. But it's important to note that innovation is not the same as copying, and not everything that is new is called innovation. Of course, innovation can also be an improvement to existing products. iphone introduced facetime instant video calling in 2010, along with the famous iphone 4 (based on an upgrade to the iphone 3Gs). facetime is arguably one of the most innovative inventions in mobile media. Although the initial experience and cost (expensive data) were not satisfactory, it brought a new way of instant communication with more emotion.

Kids can only play games for 90 minutes a day in China

#Smartphone Dependence

It is not smartphones that are destroying teenagers, but society and the education system. Heavy schoolwork deprives teenagers of time for outdoor activities, and stress can only be relieved by video games. Policies that restrict teenagers' gaming time cannot solve the root of the problem.
