Abstract:
A hand-held mobile mouse for a computer system having an associated screen comprising:(a) a housing having a shape designed to be held in a user's hand, said housing having a top portion with an opening and a lower portion; (b) a sphere rotatable in any direction in said housing and having a portion partially surrounded by said opening so that said sphere is readily rotatable by the user's thumb when said lower portion of said housing is held in the user's palm; (c) a rolling movement detection unit for generating a cursor signal in response to rotation of said sphere for cursor movements on the screen of the computer system; (d) a plurality of spring units mounted in the housing for vertical movement of the sphere to generate a signal to activate a computer programmed click function operation; (e) four roller units mounted to support a lower surface of the sphere and enclosed within said housing by said lower surface of said sphere; (f) a remote wireless signal unit for converting the signals from the rolling movement detection unit to signals transmitted to the computer system; (g) a circuit board connected to remote wireless signal unit; and (h) a receptacle for batteries formed within the housing; wherein said rolling movement detection unit forms signals processed by the computer system to produce cursor movements on the screen of the computer system corresponding to the rotation of said sphere; and wherein said cursor movement can be continually produced on the screen of the computer system in any direction in two dimensional space corresponding to the rotation of said sphere pushed by the user's thumb during activation of the computer programmed click function operation by vertical movement of said sphere pushed by the thumb simultaneously.
