Posture measurement and feedback instrument for seated occupations

A method for posture feedback to a computer user and storage of posture data of said computer user comprising the steps of:

• (a) connecting an output of a posture sensing means to the computer of said computer user,
• (b) installing software on said computer which allows said computer to store said output from said posture sensing means and a posture threshold value, and
• (c) generating a feedback signal based on said output while said computer is being used for an unrelated purpose,
• wherein said feedback signal alerts said user if said output reaches or exceeds said stored threshold value.

A method for providing immobility feedback comprising the steps of:

• (a) sampling posture data obtained with a posture measurement means with a defined sampling frequency,
• (b) subtracting values of consecutive samples,
• (c) adding the absolute values of said differences between said consecutive samples,
• (d) comparing said sum to a threshold that defines immobility, and
• (e) alerting a person if said sum meets or exceeds said threshold.

A method for providing automatic exercise feedback comprising the steps of:

• (a) compiling a menu of exercises suited to reverse or prevent the harmful effects of postural dysfunction,
• (b) collecting posture data with a means of posture measurement,
• (c) comparing said data to a threshold that defines said postural dysfunction, and
• (d) automatically selecting exercises from said menu that are best suited to reverse or prevent said harmful effects of said postural dysfunction when said threshold is reached or surpassed.
