Abstract
A support device for a computer mouse (mouse pad) comprises, extending over the lower foil made of foam material, at least one thin, colored liquid layer which is enclosed between two foils welded together along the edge in a liquid-tight manner and is visible through the transparent foil or foils. The liquid occupies the available cavity only incompletely and it spreads out in puddle-like patterns to define void spaces which change continuously due to the actuation of the mouse, thereby providing the mouse pad with an optically interesting appearance.
Claims9
A device for supporting a computer mouse on an underlying surface, said support device comprising:
- a lower foil made of a material for holding the support device on the underlying surface;
- a carrier layer laminated over the lower foil;
- a transparent upper foil which is affixed to said carrier layer to define a cavity, said upper foil having an upper surface with a predetermined surface roughness for engaging the computer mouse and allowing proper actuation thereof;
- and
- a layer of liquid disposed in the cavity between said upper foil and said carrier layer.
