History

Cinematographer MORTONHEILIG who createdsimulator SENSORAMA withvisuals, sound, vibration andsmell.

Technology

• Display.

• Tracking System.

• Devices of Interaction.

• Graphic System.

Display

Table and hand projection used asdisplays in the Augmented Realityusing Shader Lamp Technology

Head Mounted Display

• Places physical world andvirtual graphics over usersview.

• Types:-Optical See ThroughVideo See Through

• Advantages:-Provides user immersive experience.

• Disadvantages:-Inefficiency of devices with 6 DoF

Hand Held

•Employs small display that fitsuser’s hand.•Opts for Video See Throughtechnology

Advantages:-•Portability and massive availability of cameraphonesDisadvantages:-•Physical constraint to continuously hold the device.•Distorted virtual world compared to real world.

Spatial Display

•Digital projectors to projectgraphical information on physicalobjects.•Display is separated from user.•Acronymic as SAR (SpatialAugmented Reality)

Advantages:-Distinguished real and virtual reality.No limited resolution or distortion of information.Disadvantages:-Inefficient in sunlight.Requirement of surface for projection.

Tracking, Input devices and Computer

• Tracking the user’s hand and providing 6DoFinteraction technique.

• A wand with a button and a smart phone thatsignals its position and orientation fromcamera images.

• The computer analyzes the sensed visual datato synthesize and position augmentations.

Software and Algorithm

• Image registration.

• Video tracking from visual odometry.

• Steps for Image registration :

– Detect interest points.

– Detect optical flow.

• SLAM (Simultaneous Localization AndMapping)

Applications of AR

Enhance viewingof fetus inside amother's womb andformation of virtual X-ray

•Can include images of hidden objects which canbe used in medical applications.• Reduces task complexity in assembly, securityand maintenance

Task Support:-

Augmented Reality in Social Networking.

• Navigation system.e.g. : Driving lessons

by heads up display

•Education andentertainment.e.g. : outdoor

gamings

Other applications

• Advertising.

• Military & security.

• Architecture.

• Art.

• Sightseeing.

• Commerce.

• Time.

• Performance.

• Devices.

• Multi-screen simulation.

• Holodeck.

• X-ray vision.

• Gadgets.

• Automotive.

• Translation.

Limitations

• Limited GPRS accuracy.

• Accuracy should be less than 1 meter.
