Method and apparatus for estimating a motion parameter
TL;DR: In this article, the authors present a system for estimating motion parameters corresponding to a user. But the system is not designed to estimate the motion of the user, only the direction of user motion.
Patent
Golf clubs and golf club heads
John T. Stites,Gary G. Tavares +1 more
TL;DR: Golf clubs according to at least some example aspects of this disclosure may include a golf club head and a shaft configured to engage with the golf head, which includes a grip engaged with the shaft.
Patent
Video game system with wireless modular handheld controller
TL;DR: In this paper, the handheld controllers sense their own motion by detecting illumination emitted by emitters positioned at either side of a display, and can be plugged into expansion units that customize the overall control interface for particular applications including but not limited to legacy video games.

Game operating device
Akio Ikeda,Kuniaki Ito +1 more
TL;DR: In this article, a game operating device (controller) includes a longitudinal housing, and a holding portion held by hand to be wrapped by its palm it is formed in the housing, where a direction switch is provided on an upper surface at a position where it can be operated by thumb of the hand holding the holding portion, and start switch and a select switch are provided backward thereof.
Patent
Accelerometer-based controller
TL;DR: In this article, a rotation motion of an input device around a predetermined direction as a rotation axis is determined by comparing a start point in a two-dimensional coordinate system which is represented by the first acceleration data obtained in a predetermined period, and an end point in the 2D coordinate system, representing the last acceleration data received in the predetermined period.
