Provided is an information processing device including: a sensor data acquisition unit configured to acquire sensor data provided by a sensor worn by a user or mounted on a piece of equipment used by the user; an action detection unit configured to detect an action of the user on a basis of the sensor data, the action including a turn; and an information generation unit configured to generate information regarding the turn.

A golf club having a sensor that is removably connected at one or more positions of the golf club where the sensor comprises an inertial measurement unit including an accelerometer capable of measuring linear accelerations in three orthogonal axes and a gyroscope capable of measuring an angular rate of rotation around the same axes. The sensor may further comprise a processor which may perform instructions to detect the impact of the golf club with a golf ball and determine the start of the golf swing without any additional input from the user. The sensor may further have a power management system to extend the life of the power source.

An embodiment of an exercise monitoring apparatus is shown. Herein, the exercise monitoring apparatus comprises a casing, a fastening member, a first laser device and a second laser device. The first laser device is oriented so that, when actuated, the device outwardly projects a first light beam in a direction substantially perpendicular to a top surface of the casing. The first light beam visually produces a line of light. The second laser device is oriented so that, when actuated, the device outwardly projects a second light beam in a direction substantially perpendicular to one of the sidewalls of the casing and substantially perpendicular to the first light beam.

A system and method of using an exercise system having a resistance structure of handles connected to cables, which cables are connected to at least one pneumatic cylinder that creates resistance, wherein the resistance is adjusted by the user via actuators in the handles, so that the user does not need to release the handles to adjust the resistance. The system is typically supported by a frame to surround the user, and the pneumatic cylinder may be connected to an equalizing tank that may be housed within or integrated into the frame. The system may include a monitor to visually display system parameters and other information to the user. The system may calculate resistance and work done by the user by measuring piston displacement and speed, as well as using accelerometers or other devices integrated into the handles.
