It is estimated that the audience who has seen the black mirror "All Your History" will be unable to help but look at the technology of memory video in YY film. The technology of looking directly at the non-destructive image in my mind makes new car recorders, GoPro and other products weak and popular.
Although we don't have the technology to look at memory, we can try to be close to similar effects in technology. This time, we will explore with you what kind of black technology XD is like abroad and Xbo
Technical requirements
The technology in the black mirror records the memory in the brain by implanting memory chips. The visual and auditory memory of any day can be directly recalled and played back in the mind like watching live movies.
Although the current brain nerve technology has not reached this level, video+3D glasses can still achieve partial simulation. There are two requirements here. The first is to wear it with you, and the second is to record automatically.
However, due to the limited battery and storage space of the wearable devices, the products on the market adopt the mode of regular photography/video recording, and finally they are combined into a whole day video recording, which is also called LifeLog (life blog) in foreign countries.
It should be noted that sports cameras such as GOPRO and Sony Action Cam do not meet the second requirement. Although they can be hung on the body, they do not have timing photography function, and their continuous photography duration is generally only 2 hours.
SenseCam, the founder who died prematurely
The concept of this type of camera first appeared in 2009 and was launched by Vicon Revenue of Cambridge. It was originally designed for patients with Alzheimer's disease (Alzheimer's disease). The original intention is to let patients look through the manually recorded life clips to arouse memory.
SenseCam is designed to take a picture every 30 seconds, and will recognize the environment according to the built-in accelerometer, temperature sensor, electronic compass and light sensor. When entering a new environment, it will also automatically take pictures to completely record any special moment.
SenseCam is 6.5x7x1.7cm in size and weighs 94g. It has a built-in 2G memory and can store more than 30000 photos.
Although the size is not too small, it can still be hung on clothes. But what is disappointing is that its camera resolution is only 640 * 480, and the original price is 500 pounds (about 4900 yuan).
In addition, it was originally scheduled to be launched in 2010, but now we haven't seen the news of mass production, so naturally we can't find it on XBao.
Narrative clip， The most famous mass production machine
The Narrative Clip is launched by Swedish Narrative (formerly known as Memoto). Its photo interval is also 30 seconds (120 pieces/hour).
The body size is 3.6 * 3.6 * 0.9cm, and the weight is 20g. It is the smallest "life recorder" at present. The wearing position is naturally on the collar, button or backpack belt.
The machine camera has a resolution of 5 million pixels (70 degrees wide angle), built-in accelerometer, magnetometer, GPS and 8GB storage (4000 photos can be saved), and a single 24-hour endurance.
The machine provides three colors: white, gray and orange. It also has its own cloud storage service, but this service is mandatory and only free for the first year. After that, it will cost $9 per month. But in China, I'm afraid that continuous fees are a problem
The price of Narrative Clip is not low, which is 279 dollars, and about 1800 yuan on Universal X.
Autographer， The most options are the most expensive
Autographer, launched by OMG Life, is equipped with sensors such as color monitor, temperature sensor, magnetometer, accelerometer, etc., and provides lanyard. Users can also clip it in their belt or jacket pocket.
It is equipped with a 5 megapixel fixed focus camera with a 136 degree wide angle of view, 8GB storage, up to 28000 pictures, and can store content for more than 12 days.
It can be seen from the image compression that its photo quality is not as good as that of Narrative Clip, and the client only supports iPhone for the time being.
There are keys on the body to adjust the photographing frequency (high, medium and low 3 gears). Usually, data is transmitted through Bluetooth, and charged through USB port, with a single 10 hour endurance.
In order to protect the privacy of innocent passers-by, the machine specially uses yellow paint on the edge of the lens, and the notification light will be forced to flash when shooting.
At the same time, its price can also catch up with the original price of 400 pounds/650 dollars, and now the price of XBao is about 3200 yuan.
ParaShoot， Intermittent life video
Its principle is different from other products. It runs in the mode of recording 5 minutes every half an hour. The camera resolution is 8 million pixels and supports 1080P video recording.
The size of the machine body is 45 * 45 * 15mm, and the weight is 36g. It has a 700mAh battery built in. It needs another TF card to work.
The way of wearing is also pinned on the clothes. It is also the only similar product that supports customized patterns.
It is also the only recording camera that supports iOS, Android and Windows Phone at the same time.
Its price is $269, or about 1650 yuan. Although there is no original matching on the X Treasure, its shape has become a template for a bunch of counterfeit goods (the average price is 500 yuan), but it is impossible to know whether they support life records (regular photography).
Futures: products still in crowdfunding or not in mass production
NewViewWear, which is sold with clothes, has a large machine, 3D 50 * 36 * 10mm, weighs 28.3g, and sells for $189.
The decent Lightbox sells for $149.
Sony launched the Lifelog camera on MWC2014 in March. The price is unknown.
Of course, how can the omnipotent X-treasure and Huaqiangbei be absent? However, all that can be found are pet cameras. Their original design "users" are all pets, and their shapes and parameters can only be hehe (high energy in front).
The No. 1 player is a pet camera, which is a male model product. There is no specific brand. The price is between 150 and 198 yuan. The body is 57.5x53x31mm, 35g, splash proof, and equipped with 1.3 million pixel camera.
Because it has Huaqiang Beihei technology bonus, and supports interval photography and interval video mode, and it is the only similar product with a display (0.8 inches)!!
But wearing it on my neck, it seems that the lovely wind is too strong and the picture is too beautiful to look at
Player 2 is also a pet camera with the same parameters as Player 1 (it should be the replacement product of Player 1). Although it is more elegant in appearance, its advantage is that it costs only 80-90 yuan.
Price and experience
This kind of wearable camera has incomparable advantages in recording life and even taking pictures secretly. It can even make us feel more comfortable helping grandma cross the road, but there are still many problems in their popularity.
The first is the price. Even the cheapest Narrative Clip costs about 1800 yuan. The counterfeit goods worth more than 100 yuan hit the camera parameters and volume.

Actual performance of 1.3 megapixel pet camera
In terms of effect, all existing products are not optical shake proof and waterproof. At the same time, due to the size of the sensor, the effect must be weaker than that of the mobile phone, and there are many weak light and noise points. Another problem is the 30 second photo interval, which is actually not a complete record of life.
They are equipped with sensors to capture special moments in order to make up for the 30 second interval. However, if the shutter and anti shake are not effective, they may not be able to capture some important moments.
Moreover, the user will not be deliberately righted after wearing it, and the shooting effect will basically rely on luck. Moreover, because the effect cannot be previewed in real time, the placement angle is easy to make mistakes, and the lens is easy to be blocked by clothes.
summary
What is more regrettable than the above technical defects is that our current technology can only help here. However, whenever we think that they can record the people we see and experience every day, and can retrieve and record priceless memories and the past, it seems that this price has become acceptable.
Of course, even if you anesthetize yourself, it is difficult to anesthetize your wallet_
