Age Invaders is an intergenerational family entertainment system, which focuses on physical and social interactions using a mixed reality floor system.

The main design goals include: facilitating interactions between users with varied levels of skill in utilizing technology, utilizing the familiar physical motions from other activities to make an intuitive physical interface, and encouraging social interactions among families and friends.

Detailed implementation of the design process of our intergenerational entertainment system, Age Invaders, is covered in the article:
