Sony Wrist Projector Patent

At US Patent Office Site

It does look like there will be a conflict with the "Cicret Bracelet" and this patent, unless, the Cicret Bracelet is a Sony project. They have used "crowd funding" to test ideas.

While patents are often very valuable, they don't necessarily mean that a patented product will make an appearance any time soon. This patent was filed in the summer of 2014. 

Patents like this tell us that Sony is working with a lot of PicoP ideas, that they expect the technology to improve, and that they are busily working on those ideas, even if we don't see a lot of PR about it. (Most of the businesses that we should want to pay attention to aren't the ones that are out creating hype all the time. Their stocks do go up... but they also crash back down.

Below are some parts of the patent that are interesting. Click the link above to see it all.


There is provided a wristband type information processing apparatus including a band unit configured to be worn on a wrist of a user, a projection unit configured to project an image on a hand wearing the band unit, and a control unit configured to control the projection unit in a manner that at least one of an image that is stored in a storage unit and an image that is input from an external apparatus is projected on the hand.

16. The wristband type information processing apparatus according to claim 1, wherein the projection unit is a pico projector using a laser. 

[0059] The projector 3 projects an image (still image or moving image) on the plane of projection under control of the control unit 11. In this embodiment, the projector 3 projects an image on a hand (the back of the hand or the palm) wearing the band unit 6, under control of the control unit 11. The projector 3 is achieved by a pico projector using a laser, for example. In this case, since calibration such as focus adjustment is not necessarily performed in principle, the projector 3 can project the image regardless of a position relation between the projector 3 and the plane of projection due to the unevenness of the surface of the hand, the angle of the wrist, and the like.
