Abstract: A method of moving objects in a graphical user interface, includes obtaining a video image of a user of the interface; displaying the video image on a display such that the video image is superposed with one or more objects displayed on the display; and moving one or more objects displayed on the display based on recognition of motions of the video image of the user. Recognition of motions of the video image may include recognition of motions of an image of the user's hand.

Abstract: Atomic operations may be implemented on a processor system having a main memory and two or more processors including a power processor element (PPE) and a synergistic processor element (SPE) that operate on different sized register lines. A main memory address containing a primitive is divided into a parity byte and two or more portions, wherein the parity byte includes at least one bit. A value of the parity byte determines which of the two or more portions is a valid portion and which of them is an invalid portion. The primitive is of a memory size that is larger than a maximum size for atomic operation with the PPE and less than or equal to a maximum size for atomic operation with the SPE. Read with reservation and conditional write instructions are used by both the PPE and SPE to access or update a value of the atomic.
