Computer mice, computer mouse arrangements and mouse pad arrangements

A computer mouse arrangement, comprising:

• a ferromagnetic material on a tracking surface;
• and
• a computer mouse movable relative to the tracking surface on which the computer mouse is placed, the computer mouse comprising:
• a housing;
• a magnetic element provided on the housing;
• and
• a control circuit configured to control a magnetic attraction force between the magnetic element and the ferromagnetic material on the tracking surface;
• wherein the housing comprises a bottom surface facing the tracking surface;
• at least one foot extending out from the bottom surface;
• and
• a pressure-sensitive sensor at the at least one foot, the pressure-sensitive sensor configured to determine a pressure exerted on the at least one foot;
• wherein the control circuit is configured to control the magnetic force based on the pressure exerted on the at least one foot.

A mouse pad for arranging under a computer mouse, the computer mouse having at least one foot extending out from a surface of the computer mouse adapted to face the mouse pad and further having a pressure-sensitive sensor at the at least one foot, the pressure-sensitive sensor configured to provide a signal based on a pressure exerted on the at least one foot,

• the mouse pad comprising:
• a magnetic layer;
• and
• a control circuit configured to control a magnetic attraction force between the magnetic layer and a ferromagnetic material on a housing of the computer mouse based on the signal provided by the pressure-sensitive sensor at the at least one foot of the computer mouse.
