Adaptable Input Devices

An input device, comprising:

• a housing defining a top surface that includes controls, the housing defining a recess that includes generally opposing upper and lower surfaces that extends at least partially under and parallel to the top surface;
• and,
• a self-adjusting gripping mechanism extending into the recess through the lower surface and biased toward the upper surface, the self-adjusting gripping mechanism configured to be contacted by devices having a range of thicknesses and configured to grip individual devices within the range of thicknesses between the self-adjusting gripping mechanism and the upper surface.

A system, comprising:

• a first game controller having a first housing defining a first linear recess and a first self-adjusting gripping mechanism configured to engage a first edge of a device inserted into the first linear recess;
• and,
• a second game controller having a second housing defining a second linear recess and a second self-adjusting gripping mechanism configured to engage a second edge of a device inserted into the second linear recess.
