[Designing Future Things] How to effectively manipulate people from the perspective of the machine? Thinking about communication between humans and machines

Roughly speaking

1. Noisy hot cook. The psychology of humans and machines.
2. What is the state in which humans and machines are in harmony? Is it as safe as a dangerous airport? Bicycle traffic in the Netherlands.
3. Is humans a hassle for machines? Norman talks about the conditions of machines that harmonize with humans.

Noisy hot cook.

Recently I learned that Hot Cook speaks a lot.

Hot Cook is a rice cooker-type cooking utensil provided by Sharp, and is a great product that allows you to make anhydrous dishes that condense the flavor of the ingredients without using water, and is selling like crazy. To be honest, you can do anything, from simmering, steaming, stir-frying, to low-temperature cooking. For muscle training people, being able to mass-produce salad chicken is also great.

However, it's quite loud, wondering if this is kind or mediocre. Perhaps they applied Sharp's specialty voice recognition technology, and say things like, "Hello, the pollen is incredible today," or "The weather is cloudy." If you use it over 100 times, it's 100 times, and they say things like, "I've done it," so to be honest, it feels like there's a noisy relative.

It is also necessary to tell whether the cooking is complete or not, so it is no use for the audio itself to be generated, but it is relying too much on audio, and there are so many comments that many people will find it annoying.

What is the harmony between humans and machines?

Recently, more and more machines have the powers beyond humans. If you try to cross the lane, you will be forced to return to the driving lane. The brakes will also be applied on their own. So humans don't need to operate the car anymore? Many drivers are sleeping sharply in traffic jams.

But who will be responsible for an accident caused by fully autonomous driving? Will the manufacturer be responsible? Who should the victim blame?

There is interesting data on plane landing accidents. Generally, the landing is flat, the surrounding area is vacant and there are no obstacles such as buildings, so the safest the desert-like terrain. It should be dangerous to places where there are buildings and not even flat runways, like in Hong Kong in the past. However, there were fewer accidents at vacant airports. This is because the pilot lets himself be careful and makes mistakes that he normally doesn't make.

The Netherlands is a city with advanced bicycle traffic. In Japan, bicycles and pedestrians are fairly common, and in recent years, bicycles are organized to pass through the roadways, but in the Netherlands, bicycles and pedestrians are deliberately organized to pass through the same road. At first glance, it feels dangerous.

However, in reality, pedestrians and cyclists have become more emphasised, and accidents are decreasing. In the Netherlands, the Bon-Elf system is used to mix pedestrians and bicycles, creating an autonomous state in which the bicycles "always drive with care on the pedestrians." Norman states that there is a state of harmony between humans and machines.

From a machine perspective, humans are a hassle. The conditions for machines that harmonize with humans

There is an interesting bonus at the end of this book. It's a dialogue between machines and Norman.

From a machine perspective, humans seem to be very troublesome. He wants a sense of operation even though he can't do anything. And the machines have created laws that will effectively control humans.

1. Keep things simple.
2. Give humans a conceptual model.
3. Show the reason.
4. Make them think that they are in control by humans.
5. Continuously reassure.
6. Human behavior is not called an error.

On the other hand, the following are the rules for humans to design clever machines created by humans (or rather Norman).

1. Give rich, complex, natural signals.
2. Be predictable.
3. Give a good conceptual model.
4. The results are understandable.
5. To bring continuous awareness without any hassle.
6. Utilize natural mapping.

Looking at it, you can see that they are quite similar. This book has the distinctive feature of studying designs by personifying machines, but the similarity between the rules of manipulating humans from the perspective of machines and the rules of designing machines for human designers means that designers should have a perspective of personifying machines and designing machines.

I said at Hot Cook that he was "squeaky." It is a typical personification of a machine, but the person who designs Hot Cook needs to think about how Hot Cook speaks and touches people.

It may be difficult to grasp the details of the rules unless you read the flow of this book, so please take a look and take a look at the world.
