It was known without saying. 「No cash register convenience store」 !
It seems to be popular in Japan in the future. The "amazon go" will be increased to 3000 stores in the future. . By the way, I went to Seattle for work so I went to "amazon go" ♪ It is not interesting just to buy the original mug and chocolate of "amazon go".
＜amazon go original mug＞
＜amazon go original chocolate＞
I was interested in it, I did a little interesting experiment ♪
The experiment theme is...
Whether "amazon go" do not make a mistake in billing ...
I tried to say ♪ free research · · ·
By the way, in "amazon go", I hear that the product and the recognition of the customer are done by the camera on the ceiling. Hum.
＜camera on the ceiling＞
Based on that, I made a hypothesis.
「Hypothesis that a billing error occurs」
I considered the hypothesis as follows.
1. From the camera on the ceiling, there should be a blind spot somewhere.
2. The camera can not recognize the motion performed in the invisible place.
Based on the above hypothesis, I tried to experiment, but never damaged the amazon go.
Then, I would like to follow the experimental procedure!
❶ First, look for the largest item and the smallest item in the amazon go store.
❷ And then, put the smallest item in the shopping bag.
❸ Then put the largest item in the shopping bag.
❹ Next, in the shopping bag, pick up small item in the shade behind picking up large item.
❺ Next, when returning a large product to the original shelf, the small product is also returned to the shelf behind it. ※ At this time, the camera assumes that it can not recognize that the small item has been returned to the shelf.
❻ Leave the store as it is. The actual shopping bag contains neither large item nor small item, but in actual accounting, it is expected that small item will be billed. amazon go will recognize that a small item has been purchased.
Following is an actual experiment result.
The smallest item was mint.
At first we put it in shopping bag ♪
The biggest item was serial.
This was also put in the shopping bag ♪ You can see the difference in size.
Also add Oreo cookies.
From this situation, cereal and mint were returned to the shelf at the same time. You can see the mint in the back. I hid the mint behind the cereal box and put it back on the shelf.
As a result, the condition of the shopping bag is below. Only Oreo remains in the shopping bag.
And I passed the gate as it is.
After passing the gate, after a while, a receipt was sent to the my smartphone, which is the picture below. . .
"Amazon go" did not seem to recognize that I returned mint. As hypothesized, it seems that the return of products that can not be seen by the camera can not be recognized and a billing error occurs. Naturally, Mint was returned to the place where it was originally, in order not to bother Amazon Go. Of course, I kept the bill and did not refund the mint. I am grateful to amazon go for helping with the experiment. It was good result according to the hypothesis♪
It is an experiment using original chocolate in amazon go. A bunch of chocolates are displayed on the shelf. So I immediately grabbed eight pieces and quickly put them in shopping bags. I immediately passed through gate and went out.
It was counted properly. Even if you grab multiple pieces of chocolate, the accuracy is perfect if you can capture the camera firmly ♪
