A system and method for interfacing with a personal telephony recorder is provided. Users can issue commands to the personal telephony recorder through a variety of means. A user using a device with video capabilities can use facial cues, such as a facial expression, that is recognized as a command and sent to the personal telephony recorder. Video-based users can also send commands using a Doppler shift created by moving away from or towards the video recorder or a portion of the recorder. Personal telephony recorder users that use a pervasive computing device, such as a handheld computer or personal digital assistant, can issue commands by using a thumb switch usually located on the side of the device, or by using a stylus to select portions of the device's screen, such as command buttons.
