- the training would commence with basic training at a shooting range, followed by more complex scenarios such as squad trainings.
- the marksmanship training would usually be done with live fire, at large facilities, and under supervision of paid instructors. This form of training was necessarily expensive, and also did not necessarily provide training of satisfactory quality.
- simulators were introduced to the world of training, allowing simulation of various environments for a limited number of trainees.
- the simulators were expensive to build and maintain, and often incorporated different equipment than what the user would actually have in combat.
- the system includes a small device, containing sensors, that is attachable to the rail, or a different portion, of the firearm.

- the processor 150 includes wireless communication hardware, for transmitting data back and forth between a user device such as a smartphone or tablet.
- processor 150 includes a barrel tracking module. The barrel tracking module detects a change of orientation of images captured by the image sensor 146, and uses this change of orientation to track movements of the barrel of the firearm, even without input from IMU 142.
- microdisplay 160 may comprise, for example, an OLED or LCD screen.
- the microdisplay 160 may be used to project images or instructions to a user.

- smart aiming device 100 when operating in the locked fire mode 114, functions as a fire control system.
- fire control system refers to a system that controls when a firearm is discharged. Such a system detects and locks onto a target and tracks the point of aim of the firearm relative to the target. Once the target is acquired and locked onto, the system waits for the firearm to be correctly oriented and positioned (for example, in direction or elevation) before allowing the firearm to discharge. In exemplary embodiments, even when a user holds down the trigger, the weapon will only discharge when the weapon is pointing in the right direction.
- the processor 150 takes into account not only the relative position of the firearm to the target, but also factors such as speed of the target, distance, slope (ballistics), roll, wind, air pressure, and involuntary movement of the firearm caused by the user.
- the processor 150 may be configured to time the firing based on the type of ballistics.
- the processor 150 detects a specific target zone, or "epsilon," at a central location on the target.

- the processor 150 includes a module configured to provide feedback 120.
- the module is a computer program product, stored in a non-transitory memory of the processor 150, that, when executed by the processor 150, causes the processor to provide feedback to the user.
- the smart aiming device 100 uses the same hardware components (e.g., sensors 140, processor 150, and microdisplay 160) that were used in the operational mode 110.
- the smart aiming device 100 instead of using the sensors only for improved functioning of the firearm, the smart aiming device 100 also analyzes user performance and may instruct users how to improve their marksmanship and operational techniques.
- the feedback 120 is generated based on the data gathered with the sensors and analyzed with the controller.
- the feedback 120 may be provided to the user while the smart aiming device 100 is within the operational mode 110, as indicated by arrow 127. While within the operational mode, the user requests the feedback 120 following firing of the firearm.
- the feedback 120 may include, for example, analysis of how much the actual point of aim deviated from the intended point of aim.
- smart aiming device 100 may be operated in a dedicated training mode 130.

- the user enters the dedicated training mode 130 prior to shooting a series of one or more shots, and device 100 automatically provides feedback following completion of the series of shots, without further prompting.
- the feedback provided in the dedicated training mode 130 may be more robust than that provided in the operational mode 110.
- the dedicated training mode 130 may utilize the entire micro-display 160 to provide the feedback, whereas the feedback within the operational mode 110 may include feedback only on a small portion of the micro-display 160. This limited display of the feedback permits simultaneous operation of the firearm.
- the dedicated training mode 130 may be used to provide additional types of feedback, as will be set forth herein.
- the smart aiming device 100 may provide feedback 122 to a user regarding aiming or firing technique. Such feedback may be applied regardless of whether the user was previously using the firearm in an unlocked mode 112 (which generally does not require use of the sensors 140 or processor 150) or in locked fire mode 114.
- the sensors 140 continuously collect data during operation of the firearm, even in the unlocked fire mode 112. This data is stored in the memory of processor 150 and analyzed in order to provide feedback. Examples of this feedback will be provided further herein.
- the smart aiming device 100 may also provide instruction 124 on the use of the locked fire function 114.

Examples of this feedback will also be provided further herein.
- the smart aiming device 100 may be used to provide simulations 132.
- at least one virtual target is projected through microdisplay 160.
- virtual targets include an augmented reality target (i.e., a target overlaid onto a real-world image) and a virtual reality target (i.e., a target within a scene that is entirely projected by the micro-display).
- the device 100 provides feedback about a series of shots 134.
- the feedback may include statistics about accuracy or consistency of the timing of the shots throughout the entire firing session.
- the same hardware components that are used in the operational mode 110 are used to provide inputs for the feedback, whether in the operational mode or in the dedicated training mode 130.
- the user is able to perform the training on the exact same gear installed on the firearm that he or she will use during live fire situations, without changing the look or feel of the firearm.
- FIG. 2 schematically depicts hardware components of smart aiming device 100, according to embodiments of the present disclosure. In addition, typical functioning of the hardware components in the operational mode is described.
- Smart aiming device 100 is affixed onto firearm 101, and generally aligned with bore 102 of the firearm. Bore 102 is also known as a barrel.
- Firearm 101 is depicted as a rifle; however, smart aiming device 100 may be applied onto any suitable firearm, such as a pistol, a handgun, a shotgun, a machine gun, a carbine, a revolver, a grenade launcher, or a rocket launcher.
- Smart aiming device 100 includes housing 162, which may be substantially tubular, and which may be made of any suitable material.
- Ocular 164 is arranged at the rear of device 100, closer to the stock 103 and grip 104 of the firearm 101. Ocular 164 may be an arrangement of optical lenses.
- Ocular 164 is also referred to herein as an optical window.
- Objective lens 166 is arranged at the front of device 100, closer to the barrel 102 of the firearm 101.
- Objective lens 166 is also referred to herein as a lens assembly.
- Objective lens 166 is depicted schematically as a single lens; however, objective lens 166 may consist of multiple lenses.
- Objective lens 166 may be adjustable, to enable focusing and/or zooming of the smart aiming device 100 on targets at different distances from the shooter.
- objective lens 166 includes one or more filters or apertures that may be adjusted by the user, or an adjustable focus control, in order to change the focus of objective lens 166.
- Smart aiming device 100 may optionally include additional lens assemblies within housing 102, in addition to ocular 164 and objective 166. These additional lenses may also be used for adjusting the focus of the view of the smart aiming device 100.
- Smart aiming device 100 includes a beam splitter 168.
- Beam splitter 168 may be constructed in any manner that is known to those of skill in the art.
- beam splitter 168 may be made of two triangular glass prisms which are glued together at their base using polyester, epoxy, or urethane-based adhesives.
- Incident light reflected off of target 161 enters lens assembly 166 as light beam 163.
- the light beam 163 is split into light beam 165 and light beam 167.
- Image sensor 146 is used to capture an image of the target 161.
- the image sensor 146 is integrated with processor 150. Additional sensors 140 are schematically indicated as near the processor 150, and are integrated with the processor as well.
- Microdisplay 160 is also integrated with processor 150. In operational mode, microdisplay 160 may project a digital reticle along light path 169.
- digital reticle refers to any electronically created image of a reticle.
- the digital reticle may be displayed in any shape or color, such as a circle or cross-hairs.
- the microdisplay 160 is configured to change the shape of the display of the digital reticle according to instructions from the fire control system, for example, depending on whether the firearm 101 is properly aimed at the target zone within the target.
- Beam splitter 170 refracts at least a portion of the light emitted by the microdisplay toward light path 171.
- Light path 171 thus includes both light from the lens assembly 166 and light from microdisplay 160, combined into a single view.
- User 173 views the light through optical window 164. Accordingly, the user 173 sees an image of the digital reticle superimposed over an image of the target 161.
- microdisplay 160 may display other types of display items, in the operational mode.
- microdisplay 160 may display boundaries of a target region that are calculated by a fire control system. These boundaries may be projected to overlay the image of the target that is viewed by the user through ocular 164, similarly to the projection of the reticle.
- the microdisplay 160 may project the entire scene that is captured by image sensor 146. This is especially useful at times of low visibility, such as at night, when the naked eye is unable to discern significant details in a landscape.
- a mechanical shutter (not shown) may be configured to block light path 167, when desired.
- system 100 with firearm 101 is merely exemplary, and other implementations may be used, without departing from the scope of the present disclosure.
- a single optical path 171 for light coming from lens assembly 166 and light coming from microdisplay 160 there may be two separate optical paths.
- two beam splitters 168, 170 there may be only a single beam splitter.
- an exemplary method 200 of providing training is disclosed.
- the smart aiming device 100 receives an instruction to enter the dedicated training mode 130.
- the subsequent steps are performed within the dedicated training mode 130.
- the subsequent steps are still performed, with the ability to provide feedback in the operational mode.
- the smart aiming device collects sensor data while the user is operating the firearm.
- the user may operate the firearm to fire on a real- world target.
- the user may operate the firearm on a virtual reality or augmented reality target.
- the advantages of operation with virtual reality and augmented reality will be described in detail further herein.
- the firing may also be in live fire or dry fire mode.
- the sensors provide this data to the controller, including the processor and memory, for analysis and storage.
- the processor analyzes the sensor data, to thereby determine feedback to provide about the operation of the firearm.
- the smart aiming device 100 provides feedback to the user regarding one or more techniques of firearm operation, based on the analysis of the data collected by the sensors. This feedback may be provided upon request by the user on data collected in operational mode, or may be provided automatically in the dedicated training mode, as discussed above.
- the memory has information stored therein regarding a type of ballistics loaded in the firearm, and the feedback is provided specific to the firearm and ballistics that are loaded in the firearm.
- the feedback is provided to the user by display of the feedback on the microdisplay, which is viewed by the user through the optical window 164 of the sight.
- the feedback may be provided in a textual format, in a pictorial format, or in a video format.
- a message is displayed on the micro-display, such as "Grip hold is too firm” or "Compress trigger more slowly.”
- the text may also include data regarding information such as timing of the trigger actuation, direction of the trigger actuation, or whether the target was successfully hit.
- the feedback may include, for example, an image of the scene captured by the image sensor at the time of the shot, including a mark indicating the target, and another mark indicating the true point of aim during shooting.
- the video feedback may include a playback of the sequence of aiming at the target and shooting at the target, with commentary or instructions included therein as textual and / or audio components.
- the foregoing are merely examples, and the specific mode of feedback may be tailored to the type of instruction that is being provided, as is understood to those of skill in the art.
- the sensors whose data is used to determine the feedback are the same sensors that are used in operation of the smart aiming device 100.
- no additional sensors are required for provision of this feedback, enabling the smart aiming device 100 to be manufactured compactly, and also enabling the training to be performed on a firearm that is identical in all respects to those used in live fire scenarios.
- the feedback may include feedback on how far an actual point of aim of the firearm was from the desired point of aim, during actuation of the trigger.
- the fire control system may lock onto a target, even when the fire control system is not used for controlling the firing, but rather for the sole purpose of identifying the user's intended point of aim.
- the system may recognize the desired aim point, on known or unknown targets, and optionally present this aim point to the user.
- the user may pinpoint the desired aim point, using system controls. If user's point of aim is off, the system, based on all available data, may give one more possible causes to why such a deviation happened, such as improper weapon hold, shooting position, etc.
- the feedback may include feedback regarding technique of trigger actuation.
- Proper trigger pull is a very important technique to master in marksmanship. If not done properly, for example if done too fast or in a jerking motion, the trigger pull may cause undesired movements of the barrel prior to the bullet leaving the barrel. As a result, the bullet will have an incorrect point of impact.
- the trigger sensor 144 enables the entire system to evaluate whether the trigger pull was executed properly. Information about the trigger pull may also be combined with information about the deviation of the point of aim, in order to evaluate whether the deviation of the point of aim was caused by the incorrect trigger pull.
- FIGS. 4A and 4B illustrate exemplary displays of the feedback for the abovedescribed techniques.
- a limited feedback is provided in a non-obtrusive manner on the display of the target region, while the firearm continues to operate in operational mode.
- Display 300 includes a display of circular target 304, with dot-style reticle 306 at a center thereof.
- a locked-on ellipse 310 is displayed over a portion of a human target 308.
- Other features of the scene surrounding the target region, such as trees 316, are also visible, just as in standard operational mode.
- a textual indicator 314 at the perimeter of the display 300 provides some textual feedback to the user, regarding how to improve on the previous shot.
- An icon may also be displayed in addition to or instead of the text, with the presence of the icon indicating that the previous shot included one or more of the above-described errors.
- the feedback is provided in the dedicated training mode.
- the entire display, as it appeared at the time of the shot, is reproduced in display 400.
- This display may optionally be made smaller and cropped relative to the display 300, to permit more room on the screen for feedback.
- the display of the circular target 404, dot-style reticle 406, human target 408, ellipse 410, and trees 416 are all reproductions of the view from when the firearm was shot.
- the user rolled the barrel at a high roll angle when firing the shot; this barrel roll is indicated through a tilting of display 400.
- the display 400 further includes one or more icons indicating particular errors associated with the previous firing.
- icon 418 is displayed to indicate the presence of barrel roll
- icon 420 is displayed to indicate presence of trigger jerk during trigger depression.
- the feedback may also include textual feedback, and may also address other matters such as aiming error, trigger speed, and wind.
- Consistency of Marksmanship Technique In addition to providing feedback about an individual actuation of the trigger, the smart aiming device 100 may also provide feedback about consistency of marksmanship technique during a series of shots, in the dedicated training mode.
- the feedback may relate to deviation in point of aim, trigger actuation, barrel roll, and any combination thereof, as well as any other parameters discussed below.
- the smart aiming device 100 may provide an infrastructure for building training sessions, particularly in the dedicated training mode 130.
- the device 100 may start a training sequence that requires the trainee to shoot ten rounds on a target.
- the system may provide feedback on parameters such as the time taken from an initial buzzer to firing of the first round, time taken to complete all rounds, and the mean time taken for each round.
- FIG. 5 is a graphic user interface 500 for feedback provided following a series of shots at a target 501.
- the target 501 is depicted with a series of concentric circles 503, with each circle assigned a point value from 6-10, depending on how close the circle 503 is to a center of the target 501.
- Each point of impact of a bullet is marked by a crosshairs 502.
- the user interface 500 further includes a cumulative score 504 for the entire shooting session, which is calculated based on the point values of each of the points of impact.
- the user interface may further include a time indicator 505, which indicates the average time spent in between two consecutive shots.
- FIG. 6 illustrates another embodiment of graphic user interface 600.
- Interface 600 like interface 500, includes a virtual hitmap of a target 601.
- the target 601 is shaped like a human upper body.
- Each point of impact is depicted as an "X" 602.
- a counter 603 lists the number of hits on target as compared to the total number of shots taken.
- the user interfaces 500, 600 thus simulate the physical hitmaps that a user might see if he fired a series of shots at a target range, and subsequently walked up to the target.
- this simulation is provided without any need for additional equipment, and without even requiring the user to travel to the firing range.
- the fire control system 120 of smart aiming device 100 includes a locked fire mode, which is able to lock onto and track the target even when the target moves. Likewise, the fire control system is configured to take into account the effect of ballistics when calculating the trajectory of the bullet.
- these tracking features may also be used, particularly in the dedicated training mode 130, to train the operator to properly compensate for ballistics and leading the target. Notably, this training may be used even with respect to operation of the firearm in the unlocked fire mode. Likewise, these tracking features may be provided even when the user is using a simple red dot or mechanical reticle, without relying on a reticle projected by microdisplay 160.
- the smart aiming device 100 may calculate expected deviations based on ballistics or a moving target, the smart aiming device 100 may also calculate expected deviations based on wind direction and speed. The device 100 may communicate this deviation to the user, so that the user may learn how he or she should have adjusted his or her aim due to the wind.
- the feedback includes feedback on how to operate the firearm in the locked fire mode.
- the locked fire mode 120 helps prevent most user mistakes when operating a firearm. However, like any system, it is important for the user to train how to use the locked firing mode properly to further enhance its effectiveness.
- the feedback may include feedback on the process of locking on to a target, even before attempting to fire a shot.
- a user may unintentionally perform an unneeded action that causes the aiming device to release the lock on the target and seek another target.
- a user may intentionally desire to move the lock from one target to another target.
- the user may wish to transition from the locked fire mode to the unlocked fire mode, and vice versa.
- the system may provide the user with standard sequences of training and so to provide feedback to the user, via instructions displayed in the microdisplay.
- Dry Fire Mode The training of the training mode is effective regardless of whether the firearm was operated in a live fire mode or a dry fire mode.
- a dry fire mode is a mode in which the user simulates firing a bullet by actuating the trigger, but no bullet is fired.
- the sensors are able to accurately determine the time of either a live shot, or a dry shot, as well as the aiming direction of the weapon during that time. As a result, the feedback may be substantially identical.
- the smart aiming device may be used as part of a system including reactive targets.
- a reactive target has one or more elements configured to interact with projectiles contacting the targets. When the projectiles contact the target, one or more electrical or mechanical properties of the reactive elements may change. This, in turn, causes a reaction in the reactive target. For example, the reactive target may drop to the ground, or may emit a visual signal. The system may detect this reaction, for example, with the image sensor.
- the reactive target may be a "communicative target” that includes a memory and communications circuitry, for storing information about when and where it was hit, and for communicating this information to a central processor.
- the term "communicative target” refers to a target that provides such information regarding when and where it was hit to a centralized system integrated with smart aiming device 100, such as processor 150.
- the device analyzes this data and may give live feedback about a hit to a user.
- the device may also measure features such as time to first hit, and range to the target (based on a time-of-flight calculation).
- smart aiming device 100 may also be used in a virtual reality mode.
- the processor 150 presents a virtual reality display including one or more virtual reality targets via the micro-display 160.
- the virtual reality display is a video or still image that represents a training scenario. This video may be saved in system memory, downloaded from an external device, or even may be generated during use of the smart aiming device 100.
- the user moves the smart aiming device 100, he or she sees different parts of the virtual reality display, just like he or she would have seen in a real world display. All of the marksmanship training and locked fire mode feedback discussed above may be provided in the virtual reality mode, except that typically, for safety purposes, firing while in the virtual reality mode is enabled only in a dry fire mode or while using blanks ammunition.
- Smart aiming device 100 may also be operated in an augmented reality mode.
- the processor 150 presents one or more augmented reality targets superimposed over a view obtained from the optical lens 164. This superimposition is similar to the superimposition of a digital reticle over the view from the optical lens, described above in connection with FIG. 3.
- the device 100 may superimpose images of a single target, multiple targets, or additional scene elements.
- the virtual reality or augmented reality targets are moving targets or airborne targets such as drones.
- the user simulates firing on the one or more augmented reality targets.
- nearly all of the feedback that is available following regular operation is available following operation in the augmented reality mode.
- the smart aiming device 100 may alert the user if it detects a human in the view of optical lens 164. This is especially important if the augmented reality training is performed with live ammunition.
