Creating a UI that Allows Users to
Experience the Speed of 5G (Part 2)
—arrows 5G F-51A

Posted: September 1, 2021

The arrows 5G F-51A, which is the 5G-compatible smartphone that won the 2020 Good Design Award, features the world's thinnest body for a 5G-compatible device at 7.7 mm, a frame that surrounds the body, and a classy design on the back, as well as a UI that was inspired by the speed of 5G. We asked UI designer, Kento Misawa, about the challenges he faced in designing this device, as well as his thoughts on design and how a designer should be.

Takeaways from Part 2

  • The requirement was to communicate useful functions and the experience they provide to the users in an easy-to-understand manner.
  • The first step in the design process is to visualize the usage scenarios.
  • A designer is a person who can think of and implement the ideas necessary to achieve a goal.


Communicating the useful functions and the experience they provide to the users in an easy-to-understand manner

In recent years, the increasing use of smartphones for cashless payment, video viewing, and resource-intensive gameplay requires fast operation without causing the user stress. To meet these needs, the arrows 5G F-51A is equipped with a variety of convenient features like FAST Finger Launcher and FAST App Drive, which were introduced in the previous segment, as well as FAST Share, which allows users to quickly share high-quality photos and images.

Misawa explains, "The design of the arrows 5G F-51A required us to implement Smart FAST®, which was made in response to current trends and needs, as well as a UI that communicates new functions and experiences in an easy-to-understand manner."

Misawa recalls that there were many challenges and struggles in implementing each feature, including FAST Finger Launcher. The ability to operate the device intuitively and without hesitation is part of an ideal UI, and the arrows 5G F-51A achieves this with its Slide-In function that allows users to quickly launch registered applications at any time. Misawa adds, "We still have a lot of work to do to make it easy to use while achieving useful functions and quality, but I believe we must keep pursuing the ideal.

Good design is about solving complex problems in a clear way and creating a state of cohesion

What does Misawa think about as he tries to pursue excellent design, despite the hurdle of development costs and resources that hinder the implementation of ideal UI design?

"The first step is to clarify the concepts that users will find valuable, that is, what the product solves, starting with the tasks and challenges that the users face. By thinking about this, you will be able to imagine when and where users will use the product, and you will create something that fits that scenario. While creating a UI screen, I am thinking about making something that visually shows at a glance what it does," said Misawa.

Misawa says that the first step in design is to imagine how the user will use the product. "A good design must first have a clear, strong concept. I think it has to be a concept that can solve complex problems in a clear way.

For example, in manufacturing, various issues such as problems experienced by users and development constraints are intertwined in a complex manner. When you try to solve these problems one by one, you end up with result that feels like a mismatched collection of fixes, like you're just glossing over the issues. Instead of this approach, I believe that excellent design can be achieved when the final product has a sense of cohesiveness, when it is organically created as a single product," he says.



Design is something that everyone does, and a designer is someone who can think of ways to make it happen

The arrows 5G F-51A was the recipient of the Good Design Award in 2020. When asked about his thoughts on this, Misawa responds, "The concept of this product was easy to understand. We were able to respond to needs such as cashless payment and quick operation with catchy features, and we are glad that we were recognized for that. UI design is part of the product, but I was able to get involved in a good project." Misawa then shared his thoughts on the meaning of the word "design."

"When we say 'design,' we are not just talking about the actual act of designing, but we are also talking about the act of manufacturing itself, the ingenuity required to achieve a goal, and all of these different processes. That's why it feels strange to me when people say things like, "adding design to manufacturing," or "the importance of design in manufacturing." I feel that part of design is manufacturing, and part of the ingenuity to achieve a goal is manifested in the products and the UI."

Misawa, who believes that design is something that always occurs when achieving objectives, adds, "Designers in manufacturing are the ones who construct ideas, indicate a direction, and visualize that direction. I keep in mind that design is not a job that only designers can do, but something that everyone does. It's something that occurs naturally."

If design is something that everyone does, and not just designers, what does it really mean to be a designer?

Misawa shared his own thoughts in response to this question. "I think a designer is someone who focuses on the user perspective in manufacturing and takes various approaches. A designer has the wisdom to know what kind of creative theory to use for the purpose they want to achieve. For example, a designer knows a lot of things like grammar in the native language and formulas in mathematics, and is able to combine them effectively to make them useful. Therefore, we believe that designers are important in order to reach a certain goal."

Misawa says that he would like to continue to be involved in the creation of services with a broad perspective that is not limited to only manufacturing, while specializing in manufacturing with a focus on smart devices. At the end, Misawa shared some final thoughts. "The creation of a good product is a job that I can be proud of. In order to achieve that, I think it is even more important for the entire organization to be in good shape than it is for individual designers and members of the development team to do their best. Rather than changing one thing at a time, I believe we need to have the courage to transform our fundamental way of thinking."

New technologies are emerging in the world of smart devices. As Misawa comments on how UI design acts as a bridge that links technology and people, his voice is full of anticipation for the technologies to come.
