Drill Navigator App

Here's how this concept could work:
Hand Recognition & Calibration: Once the user's hand is recognized and calibrated in the immersive space, the system identifies the start and end points of the drill. This calibration allows the app to know the length and position of the drill machine in 3D space.
Virtual Navigational Cylinder: After calibration, a virtual cylinder is attached to the drill. This cylinder acts as a visual guide, constantly informing the user of the drill's direction, position, and angle relative to the target. The cylinder could be color-coded or have markers indicating angles and distance.
Real-Time Position & Depth Feedback: As the drill moves, the virtual navigation system continuously updates the user on the drill’s depth and its proximity to a pre-set target. A HUD (heads-up display) could show distance, depth, and possible adjustments needed to hit the target with precision.
Adjustments and Targeting: Based on the feedback from the virtual navigation cylinder, the user can adjust the drill's angle or depth. The app provides real-time guidance, alerting the user when the drill is off-target or too shallow/deep.

Use in Construction and Repair
In construction or maintenance, workers often face challenges when dealing with hidden infrastructure, such as electrical wiring, gas pipes, or water supplies within walls. Before drilling or making modifications, it's crucial to know the exact position of these hidden systems to avoid accidental damage.

Fields of Application:

Electrical Work: Identifying hidden electrical cables and conduit within walls before drilling to avoid electrocution or cable damage.
Plumbing: Detecting the precise location of water or gas pipes, ensuring workers do not accidentally drill into or damage pipes.
HVAC: Knowing the pathways of heating, ventilation, and air conditioning ducts to avoid interfering with the existing setup during installation or repairs.
Masonry: In restoration projects or construction involving walls, workers can use this app to safely navigate through or around historical structures, ensuring nothing crucial is accidentally damaged.
Example Scenario
Let's say a construction worker is tasked with drilling into a wall for mounting a fixture, but the blueprint reveals several hidden water and electrical lines within the wall.

Pre-Intervention Setup:

Recognition & Calibration:
The drill is recognized by the app, and the worker's hand movements are tracked for precision.
The app calibrates the length and direction of the drill, setting up a virtual cylinder for navigation.
Procedure:
The worker positions the drill against the wall while viewing the real-time navigation cylinder projected by the app.
As the drill moves, the app continuously updates the worker about its proximity to the hidden pipes and wires, highlighting safe zones for drilling.
Execution:
Based on the app’s guidance, the worker drills into the safe zone, avoiding damage to the infrastructure.
The app provides depth and position updates to ensure accuracy.
This procedure minimizes the risk of damaging any vital components within the wall, reduces the time spent on planning, and enhances safety.

How it works

The displayed pathway is purely imaginary and intended only for planning purposes. It must not be followed during actual drilling unless full carpal immobilization is ensured. Do not perform drilling based on this visualization without first reading and fully understanding the disclaimer. This system is intended only to enhance the user’s perception of an imaginary line and intended trajectory prior to drilling. It is not a real-time drilling guidance system and must not be relied upon during actual drilling unless all required stabilization, validation, and safety conditions are met.
The visualization is provided exclusively for pre-drilling planning and spatial awareness, to sharpen Users understanding of alignment and trajectory before initiating drilling.
Please read and follow these instructions carefully.Do not perform drilling based on this visualization without first reading and fully understanding the disclaimer. 

App Workflow Overview

Hand Selection & Immersive Activation

Initially, the user selects Left Hand or Right Hand according to preference. By pressing Show Immersive Space, the application activates the immersive environment, recognizes the selected hand, and displays white virtual drill cylinders attached to it. Simultaneously, blue spheres appear at the most distal part of the index finger and thumb terminal phalanges.
Pressing Hide Immersive Space exits immersive mode, pauses navigation, and disables hand tracking.

Plane Definition & Point of Interest

When the user touches a real surface with the tip of the index finger and presses the corresponding button, a sphere is generated at the contact point.

Pressing Set 1st Point of Plane (POI) places a red sphere, defining the primary reference point for depth measurement.

Two additional points are defined by pressing Set 2nd Point and Set 3rd Point, respectively. Yellow spheres appear at the fingertip locations, typically positioned laterally to the left and right of the first point.

Once all three points are confirmed, a blue semi-transparent plane is automatically generated through them, visually representing the detected real surface.

Visualization & Measurement Frame (Head-Locked Overlay)

After the plane is defined, the Visualization Frame appears automatically.
This frame displays real-time measurement data—including depth, angles, and cylinder metrics—as a head-locked overlay.

The Visualization Frame remains fixed relative to the user’s head and can be repositioned according to user preference:

Along the X-axis, pressing “–” shifts the frame to the left, while “+” shifts it to the right.
Along the Y-axis, pressing “–” moves the frame downward, while “+” moves it upward.

Drill Alignment Procedure

To align the real drill instrument, the user grasps the proximal portion (base) of the drill between the thumb, index finger, and middle finger, then presses –In. After a 5-second delay with sound confirmation, a green sphere appears at the captured proximal position, provided the hand remains completely stable.

The maneuver is repeated at the distal portion (tip) of the drill by pressing –Out. After the same 5-second delay and confirmation, a second green sphere appears at the distal reference point.

By pressing Attach Tool, the white virtual alignment cylinders are automatically generated and precisely aligned between the two green spheres, conforming to the real drill’s orientation. If alignment is imperfect, the procedure may be repeated. Ideally, the Out (distal) green sphere coincides exactly with the drill tip.

A secondary reference cylinder remains anchored to the carpal center, ensuring stable spatial reference throughout the immersive view.

Real-Time Measurement Data

During immersive navigation, the Visualization Frame continuously displays:

Tool Distance (mm): distance from the red reference point to the tool tip (Out green point),
Tool Angle (degrees): angle between the blue reference plane and the line connecting the tool tip to the red reference sphere,
Tool Depth (mm): perpendicular distance from the tool tip to the blue plane.

All measurements update continuously in real time.

Adjustments & World Management

Object sphere radius: default 5 mm, adjustable using + / –.
In/Out cylinder length: adjustable in real time (default 260 mm).
In/Out offset depth: fine-tuned using + / – controls.
Delete World Options: removes previously defined points in reverse order of creation (last-in, first-out).
