Abstract:

A relatively stiff syringe pressure applicator having a pair of ears, the ears are overmolded with a relatively soft elastomer. A port extends through the syringe pressure applicator and is connected to friction fittings on either side of the pressure applicator.

Abstract:

Systems and methods for calibration and biasing are described herein. In one example, a method for determining a playing height of a user is described. The method includes receiving an identification of a first corner of a display screen from the user by associating a first position of a tracked object with the first corner using image data from a capture device, receiving an identification of a second corner of the display screen from the user by associating a second position of the tracked object with the second corner using image data from the capture device, and triangulating between the first and second corners and the tracked object to define a range of movement made by the user. The tracked object is held by the user. The method further includes defining a height at which the tracked object is held by the user based on the range of movement.
