Introduction

Augmented reality (AR) is an interactive experience of a real-world environment where the objects that reside in the real-world are "augmented" by computer-generated perceptual information, sometimes across multiple sensory modalities, including visual, auditory, haptic, somatosensory, and olfactory.

Introduction

The primary value of augmented reality is that it brings components of the digital world into a person's perception of the real world, and does so not as a simple display of data, but through the integration of immersive sensations that are perceived as natural parts of an environment.

Notifications from phone on glasses.

Applications

Medical:

• Visualizations aid in explaining complex medical conditions to patients.
• Can be combined with MRI or X-ray systems to bring everything into a single view for the surgeon.

Applications

Navigation and Sightseeing:

• Enhanced GPS systems use augmented reality to make it easier to get from point A to point B
• In addition to information about a historic site, applications can show how the location looked in the past

Applications

Mechanics and Repairs:

• A mechanic can see superimposed imagery and information in his actual line of sight.
• Complex procedural repairs can be broken down into a series of simple steps.
