Tetsu Sumii er av hovedpersonene bak designet av Sonys Playstation 4. Det er hans ord og tanker om form og uttrykk som har definert utseendet på Playstation 4. I et intervju med den offisielle Playstation-bloggen forteller han om hvorfor designet endte opp slik vi kjenner det i dag.
Her er Tetsus ord fra bloggen:
"I think the PlayStation brand image needs to be changed a little bit, as it's a new console, and we have to show what we're pointing towards for the future."
"So I thought it should be one of the most smart, cool, and intelligent products from Sony. Not just from Sony Computer Entertainment but the company as a whole. This should be one of the best, coolest, most sophisticated products we've created. That's what we were striving for."
"When we started the product design for PS4, we didn't start by thinking about what the shape would be. It was more about how we were going to create a new brand identity through the product. I just wanted to make a simple object for the living room. Sometimes products are a little too exaggerated. It should be simple. That's my thinking."
