Product Review – Necomimi

The science of analyzing and utilizing brain waves                              BeFunky_download (1).png
has advanced by huge amounts in only the last few
years. Scientists have created devices that allow
paralyzed individuals to control machines with
their brains to help them perform functions they
were long unable to. Almost every scientific
device ever invented was eventually transformed
into an entertainment tool; video game systems
are the result of computers originally created
for NASA and the military, for instance. In
this case, one of the first devices to utilize
brain wave technology is Necomimi, the brainwave
cat ears!

Let’s take a look at some of the features

On the surface, Necomimi appears to be a simple set of cat ears users wear on their heads. Within the simple appearance, however, lies a very sophisticated system of sensors and motors. The sensors are placed in strategic locations on user’s foreheads and earlobes to accurately read and interpret their brain waves. The motors engage to move the ears in response to the waves it senses. If the wearer is alert, the ears stand straight up. If excited, they wiggle around. And if relaxed, the ears lay down on top of the wearer’s head. The motions are intended to be very much reminiscent of an actual cat, and they succeed admirably in that goal.

How Much?

The base Necomimi set of ears is $69.99, and additional skins, such as Obsidian Black and Jungle Leopard, can be purchased for $19.99.

Things We Like About Necomimi

The science behind Necomimi is truly amazing and clearly displays just how far the science of brain wave technology has come in such a short time. Not even taking into account the science the ears utilize, though, they just look incredibly cute. When the wearer is alert and attentive, the ears stand up straight just like a cat. They would be perfect for parties, cosplayers, and they could add a whole new layer to the favorite cat costume in Halloween.

Things We Did Not Like About Necomimi

The ears run off of 4 AAA batteries, and the more active a person’s brain is, the quicker those batteries will drain and need to be replaced. Depending on the person and their typical state of mind, they might end up needing to replace them fairly often.

Is Necomimi Worth the Money?
