<p>An apparatus includes a body having a sensing switch (204) and a microprocessor unit (610) for measuring a rotation number of a hula-hoop; and a coupler (412) for coupling the body to the hula-hoop so that the sensing switch (204) can be in contact with a user body during the hula-hoop is rotated. Further, a method includes the steps of: receiving a user input from a user to initialize data to be displayed on a liquid crystal display (LCD) (202); and measuring a rotation number of a hula-hoop to display the rotation number of the hula-hoop on the LCD (202).</p> |
