The purpose of this work is not simply to create a device that uses brainwave sensors to control servos, but rather to use a specific wearable spinal structure to transform "invisible mental states" into "visible physical responses." Brainwave sensors collect data such as attention, which is then used to drive the movement of a spiky structure on the back.

In contemporary society, we are taught to control, hide, and even suppress our emotions, so anxiety, stress, and tension are often not expressed directly but accumulate internally. The purpose of this work is to release these "forcedly hidden emotions" from within the body to the outside. When changes in brainwaves are driven by servos and translated into movement of the spiky structure on the spine, it symbolizes that those suppressed emotions finally have an outlet.

I hope to raise a question through this work: If we cannot express emotions with language, can technology become a new form of expression? This wearable device allows the body to speak in place of language.
