What do consumers want out of smartwatches? How big or small should a watch be? These are just two of the many questions facing smartwatch makers, according to Sony CEO Kazuo Hirai.
Chatting with reporters on Friday, Hirai said that smartwatch technology will be constrained by how big a watch people are willing to wear, according to The Wall Street Journal.
"The jury is still out on what the consumer expects from a wrist device," Hirai said, according to the Journal. Given a choice, would people choose greater battery life for limited capability or greater capability for limited battery life? How big a watch consumers will tolerate is still unclear, he added.
That limitation sets them apart from smartphones, which have continually shifted in size and can be stuffed in a pocket or purse. Smartwatches also work in tandem with smartphones, meaning people will have to carry both with them. That could present another obstacle as users try to bounce from one device to the other.
"I look at it like a real estate business because you have limited real estate to establish your beachfront, but if you do, then the barrier to entry is very high," Hirai said. "Once you're committed to a particular product then I don't know if you want to be switching all the time."
