Back in 2015 I explored how our five primary senses—sight, smell, taste, touch, and hearing—were being re-created using sensors. Our senses are how we navigate life: they give us a perspective of the environment around us, and help us interpret the world we live in. But we’re also limited by the sensory world. If a sense is diminished, there may be a way to approximate or enhance its effects (as we do with hearing aids) or rely on another sense in a compensatory fashion (as with braille and sign language).
Today, gadgets (and IoT technologies) are being built that work in conjunction with, or completely replace, capabilities of the eyes, ears, nose, tongue, and hands. Sensory receptors can be replaced with micro-chipped devices that perform the same functions as these receptors, attached to or integrated with our bodies.
The technology in 2015 was eye-opening (ha-ha), but I wanted to examine how much things have advanced over the past few years.
