Abstract: A point of aim shows where a weapon is aimed on a target. An electronic device determines an impact location on the target of a projectile fired from the weapon, determines a distance from the point of aim to the impact location, and moves the point of aim in order to sight the weapon to the target.

Abstract: A virtual reality (VR) console receives slow calibration data from an imaging device and fast calibration data from an inertial measurement unit on a virtual reality headset. Using a model of the VR headset, the VR console identifies model locators corresponding to locators on the VR headset and generates estimated positions for locators included in slow calibration data. The VR console adjusts calibration parameters so a relative distance between estimated positions of the locators and positions of their corresponding model locators is less than a threshold value. From the estimated positions, the VR console generates calibrated positions of a reference point on the VR headset associated with images from the slow calibration data. The VR console determines predicted positions of the reference point from the calibrated positions and adjusts calibration parameters so intermediate estimated positions of the reference point are within a threshold distance of the predicted positions.

Abstract: Systems, apparatus, and methods are provided which: (a) receive wired or wireless transmission of information regarding an orientation of a weapon; (b) receive wired or wireless transmission of information regarding an orientation of a viewing area of a head-mounted display apparatus; (c) process ballistic information of ammunition to be fired by the weapon and the information regarding the orientations of the weapon and the viewing area to obtain a calculated endpoint of the ammunition to be fired by the weapon; and (d) display an icon (e.g., a crosshair) representative of the endpoint of the ammunition in the viewing area of the head-mounted display apparatus.
