A miniature electronic device senses head tilt and informs the user so as to avoid neck strain. The device may inform the user via various audio/visual alarms, and my sound based upon angle, duration, or both. Wireless interfaces to other devices may be provided. The device includes a housing adapted for mounting on a wearers head so as to move in a manner corresponding to front-to-back head movements, an input for receiving information corresponding to a particular forward head tilt angle, and a sensor that detects when a wearer of the device tilt their head at an angle equal to or greater than the particular forward head tilt angle. In particular embodiments the forward head tilt angle is in the range of 5 and 35 degrees, and more particularly approximately or equal to 20 degrees. The sensor may include a gyroscopic sensor, an acceleration sensor or, more preferably, a combination thereof.
