There are many situations that I can come up with where I would have loved to get instant feedback, but couldn’t get it. In some cases it was a lack of good design or imagination that caused this. I tried to solve two of them.

Clip Watch

Right now it’s really cold outside in Japan. On my way to the station I usually take my iPhone out of my coat pocket to see what time it is. But as you may know: using an iPhone with your gloves on is a tough task. That’s why I’ve been thinking about a watch you can put on your coat or bag, which tells me time only when I need to know.


By making it look like a button, it may go well with many kinds of outer wears.


Click the face once and it displays the time and date on the glass face for a few seconds. (I figured we usually don’t need to stare at a watch for a long time.)


Solar battery panels charges electricity for the display.

Fireworks Pinpointer

Ever wondered if there was a fun way to find out your car in a huge parking lot? I hope there is a projector that throws interesting light pictures in the air. You just find the customized light beam above your car.
