Interesting! I was wondering what in the world you could do with a computer inside a toothbrush. From the product page[1]:
- Zone reminder for uncleaned aread
- Intense pressure reminder
- Some kind of tracking through an app
- Send each other stickers through the display
Typical case of very niche/almost useful feature set for smart devices.
If the zone tracking is accurate, it could potentially help a lot of people who have trouble concentrating on brushing. And some sort of reminder would be great I'm sure.
But bundling all that with an app and a big expensive display is just silly. An indicator LED and haptic feedback for over-bushed areas would be just as good (if not better) usability.
Different in Chinese, according to some clicking around translate.google.com. That seems to be one of the big hurdles for a lot of words that are otherwise very widespread.
