(why) 9 senses ?<\/h1><\/div><\/div>\n\n

In modern science, we speak of 8 human senses, sometimes even more. This expands beyond the five traditionally known ones (sight, hearing, touch, taste and smell) into sensory systems inside our body. Below, you can find a few bits of information on each of them. If you click a sense, we will take you on a little journey through our body.<\/p>\n

Artificial Intelligence can't and shouldn't replace human intelligence<\/a> for many reasons, which is why we rather see it as a ninth sense, expanding\u00a0 our human capabilities by yet another dimension, helping us to master our complex world with the support of powerful adaptive computing.<\/p>\n

Below, you can learn a little bit more about our capabilities by clicking on a tile. The AI bar shows - from our perspective - how well AI maps our capabilities in each domain. In aggregate, however, human capabilities in moving emotionally, intellectually and physically through our real world are far more powerful than any AI currently is.<\/p>\n<\/div><\/div>\n<\/div>\n\n

Reflected light<\/span>Optical input<\/span>Vision begins when light reflected from the scene reaches the eye. Here, a small bundle of rays reflected from one point on the tree is followed through the optical system.<\/span>Light reflected from the tree<\/span>A bundle of reflected rays travels toward the cornea<\/span>Light from one scene point reaches the front of the eye<\/span>Re\u00adflect\u00aded light<\/span><\/div>
Cornea<\/span>Primary refraction<\/span>The transparent, curved cornea supplies most of the eye\u2019s focusing power. Incoming rays change direction as they cross from air into corneal tissue.<\/span>Incoming reflected rays<\/span>The curved corneal surface refracts the rays<\/span>Bent rays continue toward the pupil<\/span>Cor\u00adnea<\/span><\/div>
Pupil and iris<\/span>Light regulation<\/span>The iris changes the pupil\u2019s diameter. It constricts in bright conditions and dilates in dim conditions to regulate how much light enters the eye.<\/span>Incoming light of varying intensity<\/span>The iris changes the aperture diameter<\/span>A controlled amount of light enters<\/span>Pu\u00adpil & iris<\/span><\/div>
Lens<\/span>Accommodation<\/span>The cornea has already done most of the bending. The lens then fine-tunes focus by changing curvature, bringing rays from each scene point together at the corresponding point on the retina.<\/span>Rays already refracted by the cornea<\/span>Lens curvature fine-tunes their convergence<\/span>A small, inverted image is focused on the retina<\/span>Lens<\/span><\/div>
Retina<\/span>Phototransduction<\/span>The retina converts focused light into neural activity. Photoreceptors respond to light, and retinal circuits process the signal before ganglion-cell axons leave the eye.<\/span>Focused light<\/span>Photoreceptors and retinal circuits transform the signal<\/span>Ganglion cells send coded neural activity toward the optic nerve<\/span>Ret\u00adi\u00adna<\/span><\/div>
Optic nerve<\/span>Neural transmission<\/span>Axons from retinal ganglion cells form the optic nerve. After leaving the eye, signals pass through relay points in the visual pathway before reaching visual cortex.<\/span>Retinal neural patterns<\/span>The optic nerve carries the code into a multi-stage visual pathway<\/span>Signals reach brain relay centres and visual cortex<\/span>Op\u00adtic nerve<\/span><\/div>
Visual cortex<\/span>Perceptual construction<\/span>Visual cortex and connected visual areas combine edges, colour, motion, depth, objects, and context. Perception is a constructed interpretation of the signals, not a direct copy of the scene.<\/span>Distributed activity arriving through the visual pathway<\/span>Cortical networks combine features with context<\/span>A coherent and usable visual experience<\/span>Vi\u00adsu\u00adal cor\u00adtex<\/span><\/div><\/div>
