The idea of ​​making a projection behave like a touch screen is not new, in fact there are already some Sony projectors on the market They do the same in small projections on the table or the wall, as well as those curious mice and laser keyboards that we can buy in some Chinese stores.

But perhaps the most striking project of this genre was the Cicret Bracelet, a projecting handle concept that transformed our arm into a cell phone screen through a projection. Unfortunately the Cicret Bracelet never became a real product, but the concept impressed many, and it is thanks to this that today we see the LumiWatch with great anticipation.

Cicret Bracelet was a project that never became real, but that made us all dream of this concept of projector bracelet

LumiWatch a project that is no longer science fiction

A group of researchers from Carnegie Mellon University were given the task of making real the dream that caused many ideas like the Cicret Bracelet, and after many attempts, have presented their first functional prototype of a smartwatch with a laser picoprojector capable of generating a uniform image on our arm and detecting the touches we make on it with our fingers.

Unlike a conventional smartwatch, the LumiWatch would not have its own screen, but would use its projector (currently 15 lumens) to generate an image of up to 1024 × 600 pixels, or what comes to be approximately the size of a screen of traditional smartphone. Due to the low power of this projector, the current prototype would not be suitable for use in bright environments, but surely this is something that would be perfected over time.

To calibrate the LumiWatch to the irregular and unique shapes of each person’s arm, the device generates an interface that asks us to drag our finger across our arm to fill a bar. After that, we would already have a small home screen with a modified version of Android Lollipop that would allow us in theory to interact with all the functions of the device using the recognition of touches on the projection.

The LumiWatch uses Android as the operating system

Despite the fact that the LumiWatch is still a project that is far from being a functional product, it is very good to see that this time we already have a functional device and not just conceptual videos that only leave us with unfulfilled expectations. Its creators estimate that a LumiWatch it could cost approximately $ 600 according to the components currently used in the prototype, so it would be within the reach of many budgets to be released.
