Abstract: There is disclosed a portable programmable device including a battery, a memory and a terminal connectable to earpieces, the device including in the memory a calibration file, parameter or parameters relating to audio sensitivity of the earpieces, the device being configured to play media data including audio, and to provide audio output to the earpieces, the device being further configured to, using the calibration file, parameter or parameters, calculate a noise dose relating to a sound exposure of a user resulting from audio output provided to the earpieces, and to record the noise dose on the device, wherein the device is configured to adjust audio output level in response to: (a) audio content included in played media data; (b) the calibration file, parameter or parameters, and (c) noise dose data of the user recorded on the device. A related method and computer program product are also disclosed.

Abstract: A method of operating an interactive input system comprises capturing images of a region of interest at a first frame rate; processing a first pixel subset of images captured at the first frame rate to detect the presence of an object; and if an object is detected, capturing images of the region of interest at a second frame rate.
