"Business Development Masters", in which the Filament CEO Kakatsu, who supports a wide range of new business development of companies, talks with celebrities from all over the world, leading to business development and remote work.This time is Teppei Tsushima of Sony.
Sony's smart watch "Wena 3" will be released on November 27.Wena 3 will be newly supported to Suica, Alexa, QRIO, etc. as the third generation of the WENA series, which starts in 2016, and will release a collaboration model with Seiko and Citizen.
スマートウォッチ「wena 3」Prior to the release, we interviewed Tsushima, Sony's WENA business manager, about the functional aspects of Wena 3, business models, and open innovation.What is Tsushima who says, "I've finally been able to do it for the third generation," think why?
Increase the value of both analog clocks and smart watches
Kadokaku: Alexa is installed, Suica is compatible, and Wena 3 has a great evolution, but it may have been quite difficult to develop.
Tsushima: That's right.Wena's vision is to create a world that coexists and coexists with joy and convenience.As a mission for that, we will pursue the convenience of smartwatches, but also pursue the "joy of wearing", that is, the beauty of an analog clock.It is important to enhance both the value of an analog clock and the value of a smart watch.
ソニーのwena事業責任者である對馬哲平氏Among them, we aimed to have a function of smartwatch, which is almost the same as a general smartwatch.Alexa and Suica can be installed, and touch panel operations can now be operated, so I think it was quite realized.Also, I wonder if the convenience has increased considerably, which is supported by smart lock QRIO.
On the other hand, I thought it was important to improve the degree of freedom in design for the beauty of analog clocks.Until now, the model had various functions in the band, so the design could only be changed, but this time, the band part was freely modified and consolidated all functions in the buckle part.You can now design.
Kadai: Did you want to make it so far from the beginning?
Tsushima: I didn't think.It is the third generation, and the technology has finally caught up.As the power consumption of various sensors and CPUs has become so small, the size of the battery has been reduced, so I was able to keep it in this size.
Kadokaku: How much was the interval from the second generation to the third generation?
Mr. Tsushima: The second generation was released in December 2017, so it has been about 3 years, but it has been about a year since I started the second -generation UK development, so it is virtually 2.Is it about the year?
Kado: So it has evolved so far in two years.
Tsushima: That's it.
Kado: I see.Is there anything other company imitating Wena 3?
Tsushima: That's right ...The metal arc antenna is also designed with discrete, and I don't think it's easy to make so small.
Kado: Antenna?
Tsushima: Yes.When the antenna is covered with metal, the radio waves do not fly at all, so it is common to use resin and plastic for the exterior.However, in order to pursue a dignity, Wena 3 wanted to make an exterior with stainless steel, so I decided to make the covered metal exterior itself an antenna.It was quite difficult because it was designed with discrete ( *) without using a module at all.Also, if it is a resin, it is generally thickly 1.0 mm about 0 mm is made with metal 0.It can be made in about 3 mm, so it has the advantage of being very thin.
* Discrete: Semiconductor product parts, a general term for single-functional elements such as transistors, diodes, capacitors, and silistas (based on IT term dictionary e-words)
Kado: I see.The story changes, but I heard that the sensor for measuring the heartbeat installed in Wena 3 is now equipped with red LEDs in addition to the conventional green LED.
對馬氏：そうなんです。今回から緑LEDと赤LEDの2つを使ったセンサーに変更し、より正確な心拍数計測が可能になりました。センサー自体はソニーのセンサーではないのですが、アルゴリズムはソニーのアルゴリズムを使っています。R&Dセンターのほうでセンサーの技術開発が行われていまして、その技術を活用しています。
Kado: You're using Sony's research and development.
