In some embodiments, the systems and methods provide software that calculates (and/or calibrates) the angle of a controller relative to an anchor image. In some embodiments, the controller is in the shape of a firearm, and the angle is applied to a virtual firearm. In some embodiments, the software is configured to detect an interval of low vibration of the controller, for example, a period of calm, indicating that a user is actively aiming the controller in the shape, for example, of a firearm. In some embodiments, the software projects a virtual projectile on the movement of a firing mechanism in said controller.

In some embodiments, the software directs the display of ballistics information to a user including, for example, elevation holds for milling distance to a target of specific dimension (for example, a 12″ target or a 20″ target), wind direction and speed, direction and speed of target travel, a hit and/or miss scatter diagram, and/or a firing solution comprising, for example, range, elevation, windage, and time of flight. In some embodiments, the software is downloadable, from for example a network or the cloud.
In some embodiments, systems and methods of the present invention comprise a network, a simulation administrator connected to the network, and a user device connected to the network. In specific embodiments, the simulation administrator connected to the simulation database for data storage includes, for example, target data, firearm data, and environment data. In certain embodiments, the network is a local area network. In other embodiments, the network is a wide area network including, for example, the Internet, or a combination thereof. In particular embodiments, a network links a plurality of shooters in diverse simulated physical locations within a shared virtual environment. In further embodiments, a network links a diversity of shooters in diverse simulated physical locations within a shared virtual environment to one or more instructors. In certain embodiments, the shooters and one or more instructors are linked in consensual virtual reality by a network. In some embodiments, the network provides communication between shooters and spotters in training. In some embodiments, the network connects a plurality of shooters in training. In some embodiments, the network connects a plurality of shooters at a virtual firing range. In some embodiments, the network connects a plurality of shooters in simulated combat.
In some embodiments, the simulation administrator comprises a processor, a network interface connected to the processor, and memory connected to the processor. A simulation application is stored in the memory and executed by the processor. The simulation application comprises, for example, a ballistic solution application, and a statistics application that monitors, for example, user performance. In a further embodiment, a position application communicates with a position tracker connected to a controller to detect the position of the controller for the simulation application. A statistics application communicates with a database to retrieve relevant data and generate reports according to desired simulation criteria, such as selected firearms and cartridges, environments, target characteristics, and shooter characteristics for the simulation application. In particular embodiments, the simulation application generates and projects a ballistic solution projectile trajectory. In some embodiments, the simulation application generates an entire 3-dimensional environment comprising, for example, terrain, targets, cover, light sources buildings, plants, animals, vehicles, and the like. In some embodiments, the 3-dimensional environment is a mixture of real objects and virtual objects. In some embodiments, the 3-dimensional environment comprises mixed reality and/or augmented reality.
In some embodiments, a statistics application communicates with a database to retrieve relevant data and to generate images according to selected simulation criteria including, for example, the delay time between the shot and the impact, and diverse factors that influence projectile trajectory including, for example, information regarding external field conditions (e.g., date, time, temperature, relative humidity, target image resolution, barometric pressure, wind speed, wind direction, hemisphere, latitude, longitude, altitude), firearm information (e.g., rate and direction of barrel twist, internal barrel diameter, internal barrel caliber, and barrel length), projectile information (e.g., projectile weight, projectile diameter, projectile caliber, projectile cross-sectional density, one or more projectile ballistic coefficients (as used herein, “ballistic coefficient” is as exemplified by William Davis, American Rifleman, March, 1989, incorporated herein by reference), projectile configuration, propellant type, propellant amount, propellant potential force, primer, and muzzle velocity of the cartridge), target acquisition device and reticle information (e.g., type of reticle, power of magnification, first, second or fixed plane of function, distance between the target acquisition device and the barrel, the positional relation between the target acquisition device and the barrel, the range at which the telescopic gunsight was zeroed using a specific firearm and cartridge), information regarding the shooter (e.g., the shooter's visual acuity, visual idiosyncrasies, heart rate and rhythm, respiratory rate, blood oxygen saturation, muscle activity, brain wave activity, and number and positional coordinates of spotters assisting the shooter), and the relation between the shooter and target (e.g., the distance between the shooter and target, the speed and direction of movement of the target relative to the shooter, or shooter relative to the target (e.g., where the shooter is in a moving vehicle), the Coriolis force, the direction from true North, and the angle of the rifle barrel with respect to a line drawn perpendicularly to the force of gravity).
In some embodiments, the systems and methods comprise a program that provides shooting instructions and/or shooting calibration exercises. For example, in some embodiments, the systems and methods provide a menu and options for zeroing a simulated firearm in the virtual reality landscape (e.g., at a simulated 100 yard or a 100 meter range).
In some embodiments, the simulation application comprises information regarding external conditions in a database and/or entered by a user in response, for example, to a query. In one embodiment, data is entered into the system using any conventional input device linked to the system, such as a keyboard, mouse, touch-screen and the like. In some embodiments, preset conditions are selected from a database. In a further embodiment, a speech recognition system using a microphone and appropriate software for converting the spoken words to data is used to input data. In yet a further embodiment, cabled or wireless components from other measuring devices and sources is used to input data, for example Bluetooth components. In another embodiment, instruments for data input, for example, a Kestrel handheld device or similar handheld, weather station, laptop or desktop device, handheld global positioning system (GPS) or similar device, Leica Vector 4 rangefinder or similar device, and the like, are integrated with the computing device in such a way as to allow input data items to be made available to the ballistic program. In some embodiments, a direct connection is made between the external instruments and the calculator. In some embodiments, the systems and methods enable the user to adjust ballistic and environmental variables, threshold values and times, target acquisition device magnification and focal plane, and to calibrate center/zero aiming points in virtual reality.
In some embodiments, the simulation application employs wind information. The information may be selected or input by a user or provided as part of a pre-set simulation (e.g., randomly selected, selected based on a level of difficulty, etc.). In some embodiments, the wind information comprises simulated wind speed (e.g., in miles per hour, meters per second, kilometers per hour, or knots per hour). In some embodiments, the wind information comprises wind direction. In certain embodiments, the virtual reality simulation application projects wind arrows comprising wind velocity, acceleration, flow (e.g., laminar, turbulent or a combination of flow), and direction in 1, 2 or 3 axes.
In some embodiments, the simulation application employs information regarding the simulated rate and direction of barrel twist (that is, right or left), barrel length, internal barrel diameter, and internal barrel caliber. Spin drift is a force exerted on a spinning body traveling through the air due to uneven air pressure at the surface of the object due to its spinning. This effect causes a baseball to curve when a pitcher imparts a spin to the baseball as he hurls it toward a batter.
In some embodiments, the simulation application employs information regarding the type of projectile being used. In some embodiments, the simulation application employs information regarding the weight of the projectile (e.g., in grains). The weight of the projectile may be stored in memory and automatically retrieved by the program when the user selects a standard, defined cartridge. In some embodiments, the simulation application employs information regarding the muzzle velocity of the projectile. Muzzle velocity (MV) is a function of the projectile's characteristics (e.g., projectile weight, shape, composition, construction, design, etc.), the kind, quality and amount propellant used in the cartridge case, and the primer. Muzzle velocity is also a function of the barrel length of the firearm, such that the longer the barrel length, the greater the muzzle velocity.
In some embodiments, the system requests or measures the shooter's eyesight acuity and idiosyncrasies, heart rate and rhythm (as measured by the electrocardiogram), respiratory rate (as measured by a spirometer, capnometer or impedance pneumography), blood oxygen saturation, muscle activity (as measured by the electromyogram), and brain wave activity (as measured by the electroencephalogram), or other physiologic variable. In some embodiments, the system provides training exercises to assist a shooter in improved shooting that takes into account the shooter's biological characteristics.
In a further embodiment, the simulation system queries the user for the number and positional coordinates of simulated or actual third person spotters. In an additional embodiment, the ballistics calculator system automatically queries other units to determine the number, location and type of third person spotters and devices. In one embodiment, the shooter and spotters use identical simulated target acquisition device reticles. The simulated target acquisition devices and reticles used by shooters and spotters may be fixed or variable power. In a preferred embodiment, the spotting information and aiming points are projected on reticles shared by the shooter and spotters. In yet another embodiment, multiple shooters and spotters share optical or electronically linked simulated target acquisition devices and reticles.
In some embodiments, the simulation application employs information regarding the range or distance from the shooter to the simulated target. For example, the shooter may enter a distance estimated by reference to a rangefinder on the reticle. In a further embodiment, the distance from the shooter to the target is provided by a peripheral device, for example a simulated laser rangefinder. In another embodiment, the distance from the shooter to the target is provided by actual or simulated spotters assisting the shooter, by the use of a topographic map, or by triangulation. In other embodiments, the virtual reality simulation application of the present invention comprises images and data derived from real world landscapes obtained from, for example, Google Earth, drone images, satellite images and the like, that prepare the shooter for conditions and circumstances to be encountered at a remote site (e.g., simulated training for a future real life shooting scenario).
In some embodiments, the simulation application employs slope information if any, that is, the angle from 0 to 90 degrees up or down between the shooter and the simulated target, that is, the vertical angle when the shooter is shooting uphill or downhill. This information is used to adjust the downrange aiming point based on the projectile's flight through space from the point of firing to target. As can be appreciated, the distance to a target at a sloped angle is somewhat longer than the horizontal distance to a target the same distance from the shooter at the same level, and typically requires the shooter to raise or lower the barrel of the firearm relative to an axis perpendicular to the force of gravity. A shooter aiming downhill lowers the barrel relative to the perpendicular axis forming an angle which is the “downhill” angle. As will be understood, when the shooter raises the barrel above the perpendicular axis (for example, when shooting at a target located above the shooter), the angle formed between the perpendicular axis and the barrel will be an “uphill” angle. In some embodiments, the simulation program provides cant information.
In one embodiment, for long range shooting (e.g., from 1000 to 3000 yards or more), the simulation application employs information for the Coriolis effect and spin drift. The Coriolis effect is caused by the rotation of the earth. The Coriolis effect is an inertial force described by the 19th-century French engineer-mathematician Gustave-Gaspard Coriolis in 1835. Coriolis showed that, if the ordinary Newtonian laws of motion of bodies are to be used in a rotating frame of reference, an inertial force-acting to the right of the direction of body motion for counterclockwise rotation of the reference frame or to the left for clockwise rotation must be included in the equations of motion. The effect of the Coriolis force is an apparent deflection of the path of an object that moves within a rotating coordinate system. The object does not actually deviate from its path, but it appears to do so because of the motion of the coordinate system. While the effect of the earth's movement while a bullet is in flight is negligible for short and medium range shots, for longer range shots the Coriolis effect may cause a shooter to miss.
In some embodiments, the simulation application employs target movement information, with simulated movement relative to the shooter or, in some embodiments, simulating movement of the shooter (e.g., simulating shooting from a moving vehicle at a stationary or moving target, or running from one shooting site to another). In certain embodiments, both the target and the shooter are in motion. In some embodiments, training exercises are provided to train the shooter to accurately shoot targets moving relative to the shooter, including training to use reticle markings to estimate movement direction and speed and to efficiently target moving targets.
In some embodiments, systems and methods provide target-like movements in response to projectile strikes. In other embodiments, the simulated or actual firearm in use is configured to provide recoil, report, and muzzle movement to the user upon shooting. In certain embodiments, the simulated or real firearm is provided with, and used with, one or more simulated cartridges, or one or more magazines of cartridges.
In some embodiments, the projectile trajectory is projected before the trigger pull, after the trigger pull, or both before and after the trigger pull. In particular embodiments, the projected trajectory is modified to display the influence of individual variables alone and/or in combination on the projectile trajectory. In certain embodiments, the projected trajectory may be viewed from any perspective including, for example, from the shooter's perspective, the target's perspective, a spotter's perspective, a bystander's perspective, or an aerial or satellite perspective. In further embodiments, two or more projected trajectories may be overlaid upon one another and may be visually and mathematically compared. In some embodiments, the projectile's trajectory (i.e., flight path) is generated in a virtual world.
In some embodiments, the systems and methods of the present application are configured for the design and testing of firearms, target acquisition devices, reticles, and methods, hardware and software that provide information regarding variables that influence projectile trajectories, and their interactions in combination. In particular, systems and methods comprising virtual reality simulation applications are provided that replicate conditions that are difficult or impossible to purposefully vary during real-life, real-time testing with live ammunition including, for example, humidity, barometric pressure and elevation.
In some embodiments, the systems and methods comprise a virtual reality simulation application that simulates low light and night time shooting with, and without, illumination of various degrees of intensity e.g., with and without visible light illumination, infrared illumination, ultraviolet light illumination, thermal illumination, and the like. In other embodiments, the simulation application of the present invention is configured to test and to compare shooting performance with different light spectra and different intensities of ambient and target illumination.

In other embodiments, the target is moving away from the shooter.
In some embodiments, the virtual reality user is provided with training and evaluation in the use of a reticle comprising wind dots including as shown, for example, in
In some embodiments, the virtual reality user is provided with training and evaluation in the acquisition of basic skills comprising milling, for example, milling 12″ targets. As used herein, “milling a target” means use of a reticle as a ruler to measure a dimension of a target, then calculating the range to the target based on that measure. In specific embodiments, the target is a 12″ red circle at random ranges from the virtual reality user. In further embodiments, there is no wind. In still further embodiments, there is no aiming point solution visible in the field of view of the virtual reality user's rifle scope. In particular embodiments, milling a target comprises use of an information card and rapid range bars. In exemplary reticles, rapid range bars are located above the stadia on the a first horizontal cross-hair that intersects a first vertical cross-hair, and that provide rapid and accurate range estimates to targets of known size. See, for example,
In some embodiments, the virtual reality user is provided with training and evaluation in the acquisition of basic skills comprising second shot correction if a first shot fails to strike an intended target. For example, in second shot correction the point of impact of a missed target is observed on a grid pattern of a reticle, and for a second shot that point of impact is used as an aiming point on the target. See, for example, U.S. Pat. No. 9,869,530, incorporated by reference in its entirety herein. In certain embodiments, the virtual reality user is trained and evaluated in the acquisition of basic skills when the firing solution is slightly incorrect.
In some embodiments, the simulation applications, systems and methods of the present invention provide the virtual reality user with training and evaluation in the acquisition of intermediate skills of shooting a target with a projectile. In specific embodiments, the virtual reality user is trained and evaluated in the use of wind cosine that converts the angle of wind direction in degrees to a cosine value i.e., the virtual reality user is trained and evaluated in the use of the cosine of the wind direction to accurately account for the force of the wind perpendicular to the direction of fire towards a target. In certain embodiments, no aiming point solution for wind cosine is visible in the field of view of the virtual reality user's rifle scope. In other embodiment, the virtual reality user is trained and evaluated in the use of wind cosine information cards comprising full wind values, cosine values, ranges, projectile drops and wind dot values, for example, wind dot values in the reticle of
In some embodiments, the virtual reality user is trained and evaluated in the intermediate skill of accounting for projectile time of flight. In certain embodiments, a firing solution comprising range, projectile drop and time of flight is visible to the virtual reality user in the field of view of the virtual reality rifle scope.

In particular embodiments, one or more targets move perpendicular to the virtual reality user at, for example, a slow and constant speed of travel.
In some embodiments, the virtual reality user is trained and evaluated in the intermediate skill of milling or estimating range to diverse objects including, for example, tires, windows, doors and the like. In certain embodiments, the diverse objects are of known dimension including, for example, objects of 18″, 20″, 24″ and the like. In other embodiments, the virtual reality user is trained and evaluated in the use of information cards that provide the sizes and dimension of diverse objects. In particular embodiments, the virtual reality user is trained and evaluated in the intermediate skill of milling and striking a target when there is no wind.
In some embodiments, the virtual reality user is trained and evaluated in the intermediate skill of rapid range-finding, including, for example, 9 gun vs. 10 gun rapid range-finding. In particular embodiments, the user is provided with an image of, for example, a TREMOR reticle that depicts boxes and arrows linking one or more rapid range bars with projectile drop along a vertical cross-hair. In other embodiments, using a 0.1 mil incremental marking staircase above a TREMOR reticle primary horizontal cross-hair, the virtual reality user rapidly establishes an elevation hold for a target at a known size at a specific distance. In some embodiments, the markings are provided at 0.1 mil increments ranging from 0.5 mil furthest from the intersection of the primary horizontal cross-hair and primary vertical cross-hair to 1.0 mil above the intersection of the primary horizontal cross-hair and primary vertical cross-hair. Using a target known to be 12″ in diameter, the virtual reality user places the target between the primary horizontal cross-hair or stadia, and the range marking or range bar to achieve a best fit. Using the “rule of 10” for a “10 gun” system, the virtual reality user consults a table that provides the estimated range elevation hold for each range of a 7.62×51 (0.308) projectile: for 381 meters, 2 mil drop; for 435 meters, 3 mil drop; for 508 meters, 4 mil drop; and for 610 meters, 5 mil drop; For example, if a 12″ target fits best between a primary cross-hair and the 0.7 mil range bar or marking, the distance is 435 meters. Using a “rule of 10”, the virtual reality user then removes the decimal such that 0.7 becomes a value of 7, and is entered into the equation: 7+X=10, wherein the elevation hold is 3 i.e., 3 mils. In particular embodiment, for a “10 gun” lead hold value below a rapid range bar form the 0.8 mil rapid range bar 4 miles per hour lead hold, dividing the corresponding miles per hour value may be divided by 2. For example, for a 12″ target that best fits between a 0.7 mil range rapid range bar with a corresponding 6 miles per hour lead hold below the 0.7 mil rapid range bar, the elevation hold is 6 divided by 2=3 mil elevation hold.
In some embodiments, the simulation applications, systems and methods of the present invention provide the virtual reality user with training and evaluation in the acquisition of single variable skills in shooting a target with a projectile. In certain embodiments, the single variable is variable wind. In particular embodiments, the virtual reality is trained and evaluated in the effects of frequent changes in wind velocity and direction, and wind that gusts, on a projectile. In other embodiments, a wind clock is provided in the field of view of the virtual reality user's rifle scope.
