- 11. Augmented Reality (AR) Enhanced experience as viewed on a screen or other display. Produced by overlaying computer-generated imagery on a real-world environment. @quorralyne
- 12. Google Translate - Mobile Device @quorralyne
- 13. Virtual Reality (VR) Complete immersion into a virtual world where everything you see is computer generated. The real world is blocked from your field of vision entirely. @quorralyne
- 15. Mixed Reality (MR) The merging of real world and virtual worlds to produce a new environment where physical and digital objects can coexist and interact. @quorralyne

- 26. AR Overlay (Computer-generated Environment) Augmented Reality that maps the physical environment real-time. ...while at the same time mapping the structure of that environment. @quorralyne
- 28. Image Target The image recognized by the App, which launches the AR experience. Also known as a Marker. Images with high contrast and unique features with sharp edges are key pillars in supporting image recognition. (Tracking) @quorralyne
- 30. Markerless (Dead Reckoning) Augmented Reality that maps the physical environment real-time. Often uses a smartphone camera and sensors to position a virtual object in a room without the need for Image Targets. @quorralyne
- 32. Simultaneous Localization and Mapping (SLAM) The attempt to simultaneously localise (i.e. find the position/orientation of) some sensor with respect to its surroundings... ...while at the same time mapping the structure of that environment. @quorralyne

- 38. Location GPS based Returns Latitude & Longitude and sometimes Altitude Slight accuracy issues (10m on a good day) Not great indoors Wifi improves it slightly @quorralyne
- 39. Orientation Need a reference orientation or known orientation from which to measure Use True North Pitch, Roll, Yaw Quaternion Rotation Matrix @quorralyne
- 40. Augmented View OVERLAY 2D OBJECTS Heads Up Display Depends on Field of View Objects can be applied by spherical coordinates relative to device position SHOW 3D VIRTUAL OBJECTS Immersive interaction Use 3D X, Y & Z coordinates converted From Lat, Long, Altitude (Cartesian) Orient virtual camera to match real camera Augmented World maps larger than Field of View @quorralyne
- 42. Tango Android A technology platform from Google that allows developers to create experiences that incorporate things like indoor navigation, 3D mapping, and augmented reality. It uses computer vision to enable devices to see the world around them without relying on GPS. @quorralyne
