  • Processing collisions between digitally represented mobile objects and free form dynamically created electronic ink
    Patent number: 6722987
    Abstract: A computer user enters free-form electronic ink at run-time of an application program for manipulating the trajectories of mobile objects within the application program. Collisions between mobile objects and ink are processed by determining a collision angle that bisects a first and last intersecting point along a periphery of the first object. After the collision, the first object moves away from the ink as if the first object collided with a flat surface oriented perpendicular to the collision angle.
    Type: Grant
