Aim Assist Head-Mounted Display for Weapon Endpoint Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display systems for weapons do not provide endpoint information for ammunition within the user's forward field of view, limiting the user's ability to accurately aim and fire without obstructing their view.
Innovation Solution
A head-supported frame with a driver to display a visual indication of the calculated endpoint of ammunition in the user's 3D environment, processing weapon and viewing area orientations to provide a real-time, forward-facing display of the ammunition's predicted impact point, allowing the user to maintain a clear view while aiming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a head-mounted display is used to show weapon aiming information, then the user can see endpoint information, but the user's forward field of view is obstructed
Solution Approach 1:
The patent uses the head-mounted display as an intermediary device that receives weapon orientation data and ballistics information, then calculates and displays the endpoint information in the user's field of view without requiring the user to look down the barrel or obstruct their view. The HMD acts as a mediator between the weapon system and the user's visual perception.
Solution Approach 2:
The patent transitions from traditional 2D scope displays to a 3D spatial representation where the endpoint is projected into the user's forward field of view. By using depth information and spatial positioning, the system places the endpoint marker in three-dimensional space rather than on a flat reticle, allowing the user to maintain natural head orientation while receiving aiming information.
2Measurement precision
If the user looks down the barrel to aim accurately, then shot placement improves, but the user cannot maintain awareness of surroundings
Solution Approach 1:
The system performs preliminary calculations of the bullet trajectory and endpoint before the user fires. By pre-calculating where the bullet will land based on weapon orientation, ballistics data, and environmental factors, the system provides the aiming point in advance, allowing the user to aim without looking down the barrel while maintaining situational awareness.
Solution Approach 2:
The system provides visual feedback by displaying the calculated endpoint in the user's field of view. This feedback loop allows the user to see where the shot will land without changing their head position or line of sight, maintaining both accuracy and situational awareness simultaneously.
3Ease of operation
If traditional sighting devices are used, then the user can align the weapon with the target, but the user cannot see the actual endpoint of the projectile
Solution Approach 1:
The patent replaces traditional mechanical sighting systems with an electronic/computational system. Instead of relying on physical alignment of sights and barrels, the system uses sensors to detect weapon orientation, inputs ballistics data, and computationally calculates the endpoint. This substitution of mechanical alignment with electronic calculation provides accurate endpoint information without requiring the user to manually align traditional sights.

AI summary
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.
