The document discusses invisible computing and the Mojo Vision smart contact lens. Invisible computing refers to computers that are embedded everywhere in the environment and respond to our needs without conscious use. The Mojo Vision smart contact lens is an example of invisible computing, as it is an augmented reality contact lens that can provide data overlays and notifications using built-in sensors, a display, and Bluetooth. While the contact lens offers applications like low vision assistance and health monitoring, it currently has limitations like a one year lifespan and potential for unnecessary data collection. The future of invisible computing may include a whole network of embedded sensors that make life easier by predicting things like the weather.
