Abstract: A computer-implemented method includes defining an articulation between a physicalized object and a motion control user interface device that does not have a physical representation, receiving a motion signal with the motion control user interface device, determining a motion path of the physicalized object based on the motion signal, determining whether movement of the physicalized object along the motion path violates at least one boundary, and responsive to determining that movement of the physicalized object along the motion path does not violate the at least one boundary, applying a force to the physicalized object to move the physicalized object along the motion path.

Abstract: A computer-implemented method includes emitting a grasping ray from a motion control user interface device, sweeping a simulated physical area for at least one simulated object with the grasping ray emitted by the motion control user interface device, determining whether the at least one simulated object is graspable, and responsive to determining that the at least one simulated object is graspable, attaching the motion control user interface device to the at least one simulated object using an articulation having a stretched position and a relaxed position. The articulation is in the stretched position when the motion control user interface device is attached to the at least one simulated object.

Abstract: A computer-implemented method including defining a simulated object as being attached to an anchor point of a simulated motion control user interface device representative of a physical motion control user interface device, moving the simulated object in a first direction with the simulated motion control user interface device in response to a change in an orientation of the physical motion control user interface device, and moving the simulated object in a second direction in response to a command input using a command interface of the physical motion control user interface device.

Abstract: Protective ear shades for headwear such as caps, which shades include a pair of cupped or oblate shades extending from stitched or sewn attachment to the sides of the cap over the ears to protect the ears from ultraviolet radiation. In a preferred embodiment the protective ear shades curve from the headband or side margin of the cap upwardly and outwardly in a cupped configuration toward the crown and then downwardly and forwardly to the bill of the cap. In another preferred embodiment of the invention one or more stiffeners or reinforcements are provided in the ear shades to maintain the shades in the desired protruding, cupped and oblate configuration over the ears.
