A method for stimulating a mobile device user to correct improper posture, comprising:

• determining an actual orientation of a mobile device;
• capturing a plurality of 2D images of the mobile device user's face to determine a relative orientation of the mobile device user's head to the mobile device;
• calculating an actual head angle from the actual orientation of the mobile device and the relative orientation of the mobile device user's head to the mobile device;
• and
• providing a stimulus to the mobile device user if the actual head angle deviates from a predetermined head angle.

A mobile device for stimulating a mobile device user to correct improper posture, comprising:

• at least one orientation element,
• a camera, and
• a controller configured to read computer readable instructions and configured to control operation of the mobile device, wherein the instructions for controlling operation of the sensor system comprises instructions for:
• determining an actual orientation of the mobile device with the at least one orientation element;
• capturing a plurality of 2D images of the mobile device user's face with the camera to determine a relative orientation of the mobile device user's head to the mobile device;
• calculating an actual head angle from the actual orientation of the mobile device and the relative orientation of the mobile device user's head to the mobile device;
• and
• providing a stimulus to the mobile device user if the actual head angle deviates from a predetermined head angle.
