I am currently a member of the Human Interface Device Prototyping Group at Apple. We are a small exploratory design team of hybrid designers/developers. We explore what new technologies might bring to current and future products. It's our job invent and propose new features and sometimes entirely new products.
Most teams at Apple are dedicated to the next version of a product that will be released in six months to a year. We work outside that cycle, across all products, to create new things that might take longer or require deeper exploration.
