What is

AR??

NDMVP, Comp Dept. Augmented Reality 5/23

Introduction AR is the variation of virtual reality. An AR system adds virtual computer generated objects, audios and other scene environment to a real world environment in real time.

1.3 Spatial

NDMVP, Comp Dept. Augmented Reality 10/23

Head Mounted Display…..

1.1.1 Video See Through

1.1.2 Optical See Through

1.1 HMD

1.1.1 Video See Through

NDMVP, Comp Dept. Augmented Reality 11/23

1.1.2 Optical See Through

NDMVP, Comp Dept. Augmented Reality 12/23

1.2 Handheld Display Has attached camera

Provide video see through augmentations

Portable & ubiquitous

NDMVP, Comp Dept. Augmented Reality 13/23

Virtual information is directly projected on physical object.

Also called as projector display.

Display is separated from the users of the system.

Expandable.

1.3 Spatial Display

NDMVP, Comp Dept. Augmented Reality 14/23

2. Tracking1. Digital Cameras

2. Compass

3. RFID

4. GPS

KKWIEER, Comp Dept. Augmented Reality 15/23

Required to produce accurate registration. Used camera parameters, field of view,

sensor offset.

3. Calibration

Conclusion AR, by its very nature, is a highly inter-disciplinary field, and AR researchers work in areas such as signal processing, computer vision, graphics, user interfaces, human factors, wearable computing, mobile computing. The research topic "Augmented Reality" (AR) is receiving significant attention due to striking progress in many subfields triggered by the advances in computer speed, capabilities and etc.
