The pioneering industrial designer passed away last weekend at the age of 69.

Moggridge invented the notion of (and coined the term) interaction designthe idea that software and hardware and other products should be designed to satisfy peoples needs and desires.

He also co-founded the renowned interactive design firm IDEO, which continues to champion human-centered design. If theres a simple, easy principle that binds everything together, Moggridge says, its probably about starting with the people.

In 1979, Moggridge began designing the Grid Compass for a startup firm called Grid Systems. It is widely considered to be the first real laptop.
