US 5,344,323 A · Teaching recognition of body movement errors in dancing

Abstract

A teaching device for indicating in real time the movement of a selected part of a person's body beyond a desired boundary limit is provided, as well as a method for teaching a person to control his or her body movement in response to alarms provided by the teaching device. The teaching device includes an element for detecting movement of the selected body part beyond a boundary limit, a first alarm element for providing a first alarm indicating encroachment of a nominal misalignment zone in which the body part is nominally out of alignment with a preferred location thereof, and a second alarm element for providing a second alarm in response to encroachment by the selected body part of a significant misalignment zone in which the selected body part is significantly out of alignment with the preferred location thereof. The first alarm provided by a first alarm element is an intermittent beeping tone and a blinking light. The second alarm provided by the second alarm element is a continuous audible tone and continuous illumination of a warning light. A person wears the teaching device on, for example, an arm or a leg and adjusts the alarm limits. Thereafter, as the person executes a series of body movements, the first or second alarm will be provided if the arm or leg to which the teaching device is attached moves beyond the acceptable boundary limits of the proper position of the arm or leg during the series of body movements.

A teaching device for indicating in real time the movement of a selected part of a person's body beyond a desired boundary limit during the execution of a sequence of body movements, the device comprising:

means for detecting movement of the selected body part beyond a desired boundary limit, the detecting means including means for emitting first and second signals and means for selectively energizing the signal emitting means to emit said first and second signals, the selectively energizing means being changeable from a non-initiating condition in which it does not energize the signal emitting means to emit said first and second signals to an initiating condition in which it energizes the signal emitting means to emit said first and second signals in response ,respectively, to different degrees of movement of the device beyond a selected angle as measured between a reference axis of the device and an alignment plane in which the device normally is moved during execution of the sequence of body movements;
means, operatively connected to the signal emitting means, for providing a first alarm in response to receipt of a first signal from the signal emitting means indicating encroachment by the selected body part of a nominal misalignment zone in which the reference axis of the device forms an angle with the alignment plane greater than a predetermined nominal angle and less than a predetermined significant angle ,said predetermined significant angle being greater than said predetermined nominal angle;
and
means, operatively connected to the signal emitting means, for providing a second alarm in response to receipt of a second signal from the signal emitting means indicating encroachment by the selected body part of a significant misalignment zone in which the reference axis of the device forms an angle with the alignment plane at least equal to the predetermined significant angle, said second alarm being distinguishable from said first alarm.
