A hang-timer device is disclosed that is capable of issuing recording instructions to a recording device, such as a digital camera. The hang-timer can measure a static acceleration profile of a wearer of the hang-timer, and based on this static acceleration profile it can issue recording instructions to a recording device. For example, if the static acceleration profile changes from about 1 g to about 0 g, the hang-timer can issue instructions for the recording device to record; additionally, if the profile changes from about 0 g to about 1 g, it can issue instructions to stop recording. Moreover, the hang-timer can issue instructions for the recording device to record some period of time before a hang-time event and some period of time after a hang-time event. Various other such variations on the general notion described above are also disclosed.
