Advance notice
https://github.com/CurvSurf/FindSurface ... nsDemo-UWP

User Interface

This app supports eye-tracking features and voice commands, both built-in features of HoloLens2. During the holographic experiences using this app, Users gaze at target places in the space and activate FindSurface API functions using voice commands.

Gazing at target surfaces (Eye-tracking)

The gazing point follows where users' eyes gaze. If the eye-tracking feature isn't available for reasons like an inconvenience with eye-tracking or calibration failures, etc., disable the eye-tracking features in the settings panel. The app will allow users to use their hands as an alternative to eye-tracking. If no hands are detected, the traditional way (head tracking like what users do in HoloLens 1) is used.
Using the gazing point, users point to a place to detect surfaces and how large the target surface is. The circle around the gazing point implies the size of the target object to detect. Users can change the size using the voice commands.

Augmented Reality on Site

We have the use cases of:
1. Creation of as-built 3D CAD information for Digital maps, Advertisements, Game environment, ...
2. Overlaying 3D CAD information on hand onto the real objects.
3. ...

We can overlay the 3D CAD information on hand onto the buildings and structures, if we know the sizes, positions & orientations of real:
- 3 balls
- 3 non-parallel planes
- 2 non-parallel cylinders
- 2 parallel cylinders and a plane (the case of the video recorded)
- ...

Practically, the existing man-made stationary structures of planes, spheres, cylinders, cones, or tori can be used as permanent anchors with 6DoF info.

Every real space is a potential advertising space.
It becomes more immersive with AR glasses.

The stakes are huge.

Apple, Google, Meta (Facebook), Microsoft are striving to ...

AR Smart Signage on Cylindrical Surface

#spatialcomputing #virtualadvertising #virtualsignage #smartsignage #augmentedreality #iphonepro #ipadpro #lidar #arkit #pointcloud

Most man-made object surfaces consist of planes, spheres, cylinders, cones and tori.

Why? Because the shapes and movements of the tool are combinations of lines and circles.

The shapes and poses of man-made object surfaces obey Mother Nature's law; gravitation and dynamics.

Man-made object surfaces are ubiquitous.

The future market for AR displays on man-made object surfaces is huge.

The FindSurface runtime library detects and measures the shape, size, position and orientation of artificial object surfaces.

Tools used:
- Apple iPhone 12 Pro
- Apple ARKit 4
- Apple Metal API
- CurvSurf's FindSurface runtime library .

The FindSurface runtime libraries for Android, iOS, Windows, UWP, Linux along with the source codes of demo apps are available on GitHub CurvSurf.

Bill Gates personally reviewed the state-of-the-art AR glasses & HMD hardware. I bet the next consideration will relate to the software.

The source codes of the demo App 'FindSurface-SceneKit-ARDemo-iOS' are public.

Overview
This demo app demonstrates a real-time AR SceneKit application using FindSurface to search point clouds, which ARKit provides, for geometry shapes. The source code of this app is based on the Xcode Augmented Reality (SceneKit, iOS) template project. FindSurfaceFramework is required to build the source code into a program. Download the framework here and refer to here for an instruction about how to setup your project to build it with the framework.

Prerequisites
This demo app requires the LiDAR sensor to get a point cloud from ARKit:
  • Apple iPad Pro LiDAR
  • Apple iPhone 12 Pro
  • Apple iPhone 12 Pro Max
  • Apple iPhone 13 Pro
  • Apple iPhone 13 Pro Max
Output Example
FindSurface-SceneKit-ARDemo-iOS LiDAR
