SwitchU is designed for couples in long-distance relationships. The device is a pair of robot arms. One guides the arm to operate a home appliance once and the arm will be able to repeat the task. When each one of the couple have set up their SwitchU, the device will always be activated synchronously - although different tasks are assigned. For example, couples may both set up SwitchU for operating water cattle. When one cooks water for her-/himself, she/he also activates the remote robot arm to cook water for the partner.

Emotional expression, physical contact, joint activities, gift giving, etc. - there are many different ways how humans create feelings of relatedness with intimate partners - also in remote, indirect or asychronous situations. Technology and artifacts shape these experiences. Consequently, there is a huge field of research waiting to be explored.
