Augmented Reality (AR) merges real-world environments with computer-generated data and is utilized in various applications such as advertising, education, tourism, and gaming. Key challenges include tracking accuracy, occlusion, and natural interaction via gesture or speech recognition. Future trends involve improving interfaces and reducing system delays for enhanced user experiences.

5.  Augmented reality (AR) is a field of computer research
which deals with the combination of real-world (reality) and
computer-generated data (virtual).

6.  Real world exists in virtual

22. Tracking in AR
Static errors Dynamic errors
- Optical distortion, glare,
focus
- Mechanical misalignments
-Tracker errors
- Incorrect viewing
parameters
- When the viewpoint or the real objects
begin moving
- System delays which is must respond
within milliseconds
Rule-of-thumb: 1 ms delay = 1 mm error

25.  Occlusion - The potential of objects can be viewed and examined
: allows a smooth fusion between real objects and virtual
properties : Marker detection process
 Robustness - Allows a smooth fusion between real objects and
virtual properties in propose processes without delays/lags :
Accurate tracking system
 Natural Interaction – Replace paddle-based metaphor : use real
hand gesture to manipulate 3D objects. : Sensor-based Hand
Tracking and Object manipulation
 Speech input – User uses speech input to give a command to the
3D objects – more natural without input devices such as
keyboard : Speech recognition
