A multi-screen electronic device includes a first electronic device having a first electronic device screen and a second electronic device having a second electronic device screen. The first and second electronic device screens are stacked and on different planes when the multi-screen electronic device is in a compact form. The first and second electronic device screens are unstacked and on the same plane when the multi-screen electronic device is in an expanded form. A translation mechanism is coupled to the first and second electronic devices. The translation mechanism is configured to guide a motion of at least one of the first and second electronic devices along a nonlinear path such that a travel along the nonlinear path in a forward direction transforms the multi-screen electronic device from the compact form to the expanded form and a travel along the nonlinear path in a reverse direction transforms the multi-screen electronic device from the expanded form to the compact form.
