This document discusses augmented reality and blockchain technologies. It describes how augmented reality works using plane detection, feature recognition, and automatic plane joining. Potential uses of augmented reality include 3D mapping, navigation paths, and attaching information to locations. Open source projects can help develop augmented reality applications. Blockchain works by creating blocks of transaction details, hashing blocks, and using digital signatures to verify transactions across nodes without exposing private keys. Conversational AI could use phonetic algorithms to provide university information to services like Alexa in multiple formats.

2. Augmented Reality (How it Works)
1. Plane Detection using combination of
Accelerometer, Gyroscope, Visual
Patterns, and a fair bit of trigonometry
a. Uses “Feature” recognition, which is
on the most basic level noticeable
pixel differentials (color, brightness)
2. Automatic Plane joining between multiple
recognized planes ( Generating a Full
Navigation mesh )

3. Augmented Reality (Potential Use Cases)
1. Mapping a 3d environment, but using ARKit to develop
the meshes for the environment rather than existing
non-accessible and expensive technologies
2. Preparing paths to individual walkable areas based on
navigation meshes provided automatically by ARKit (or
other VR SDK’s)
3. Saving those 3d models and navigation meshes and
placing anchors for classroom Information
4. Attaching Generated Navigation
Maps to external Geo-Coordinate
Extents to orient the generated
model in the real world

4. Augmented Reality (Open Source Projects)
1. Existing Open source projects and
knowledged can be leveraged to
bootstrap projects
2. Information can be anchored to
GeoCoordinate or indoor 3d planes
3. Accessibility options deaf or hard of
hearing students can be generated
a. Combining voice to text and
AR features to recognize
where sounds are coming
from and subtitling

5. Augmented Reality: Tools of the Trade
3D Modelling and Scene
Generation Engines
AR device toolkits
For utilizing complex Device
Hardware into software
applications
For creating placeable
content,overlays, and scene
objects for
ARKit (Apple) ARKit (Google)

6. Blockchain (How it Works)
1. Block created with the details of
some type of transaction
2. Block is hashed using some
type of hashing algorithm and
used for the next block.
3. The introduction of a proof
mechanism ensures that the
parties who engaged in the
transactions can verify that they
did, while not exposing the
method for writing their
“signature”.
4. In this case a digital signature is
derived from a private key
Verifying a blockchain requires a large
amount of redundant copies of the existing
blockchain ledger stores being held across
proof and client nodes - ANTITHETICAL to
the efficiency and normalization procedures
of normal databases

8. Conversational AI & VUI
Using Phonetic Similarity Algorithms to redirect information provided by services like Alexa, Amazon.
Provides a new access point to University Information, bulletins, in many different formats like text, text to
voice and other features of importance
Potential use cases include providing daily university activities, closings, accessibility of text contentfor the
