This project explores the perception of space. Visual sense enables us to recognize a space through the detection of light present in space. The visual perception of space by the eye is complemented by the use of the camera obscura, a system consisting of a box that, by means of an opening in space, is penetrated by light, thus creating an inverted image of the exterior. The object used in order to combine both systems is a helmet, acting as a viewfinder. It reveals the rays of light that create the flipped image of space that, outside of the helmet, is perceived by the visual organs. This interaction created a portable and personal system for the perception of space and the reflection of what we usually see.
