Milgram coined the term “Augmented Virtuality” to identify systems which are mostly synthetic with some real world imagery added such as texture mapping video onto virtual objects

.

• ” Human Interaction With 3D Objects Via, AR ” is the very first step of the development of the project

• In this module we will demonstrating human interaction with a cube generated.

• In this phase we have succeeded to generate a cube & had given some motion to it by moving the marker.

• Marker is the stage where a virtual objects are augmented

• They must be square.

• They must have a continuous border

• They must sit on background of contrasting color.

• The final constraint is that the area inside the border, which we refer to as the marker image, must not be rotationally symmetric

• This concept is used to augment multiple objects at the same time

• Multiple markers are recognized by a pattern called as pat file

• The cameras can identify and distinguish this marker using .pat file

• The .pat file consists of co-ordinates of a marker generated by another application

• The concept is used to make real time augmentation

• Traditional Markers are printed on a paper making it uneditable.

• They are not programmable

• Reduces the time efficiency of program

• Limits the no. of markers to be places in front of webcam

• Unable to generate real-time effects

• It is digital in nature• As many no. of

markers can be generated and can be stored in system

• It will give realtime effects

• It is dynamic• It is Programmable

• Will support principles POP, OOP & RDBMS.

• It will give improved imaging & visualization.

• It will support direct interaction with virtual objects generated by computer.

• It will support concepts of surface computing.

• Software Requirements• JDK 1.6• Netbeans IDE 6.5 and above• Java Media Framework (API)• java 3D architecture etc.

• Hardware Requirements • High Speed Computer (High Configuration)• 3 GB or more RAM• Graphic Card• Web Cams & CC TV camaras• Infrared beamers• IR Filter Cameras• Surface Computing System(alternative)
