Abstract: Embodiments related to in-air cursor control solutions are disclosed. For example, one disclosed embodiment provides a method of moving a cursor on a display. The method comprises receiving an external motion signal from an image sensor that is external to a handheld cursor control device, receiving an internal motion signal from a motion detector internal to the handheld cursor control device, and sending an output signal to the display to change a location of the cursor on the display based upon the external motion signal and the internal motion signal.

Abstract: A first software program executing on a computing device emulates a second computing device executing a software program using emulated memory. The first software program permits the second software program to perform an operation on a contiguous portion of the emulated memory only when a pointer and a table entry both contain the same identifier, thus protecting against common types of memory usage errors in the second software program. The pointer has an address to the contiguous portion. The table entry maps to the contiguous portion. A plurality of table entries map to a respective plurality of contiguous portion of the emulated memory. A plurality of the pointers each contain the address to a respective contiguous portion of the emulated memory as well as containing an identifier corresponding to the respective contiguous portion of the emulated memory. The second computing device can be high or low in resources.

Abstract: Functionality is described for controlling the playback of a recorded media program. The functionality formulates initial playback decisions that govern the playback of the program based on a set of initial assumptions. The functionality then formulates modified playback decisions that define the manner in which the program should actually be played back. The modified playback decisions can be formed based on the playback-related behavior of a population of users who have previously consumed the same program. The functionality makes modifications which affect the playback of the recorded program based on the modified playback decisions, such as by bookmarking or truncating the recorded program.
