B.) Fill in the blanks using the words from the help box:

[  modern,             smartphones,             reflectors, 

              vision,         Maya,             Blender,              

mapping,               HDMI     ]

 

1)    AR uses computer  vision  as well as depth tracking in order to show appropriate content to the user.

2)    Smartphones  are very applicable for AR because they contain integrated GPS, sensors, camera accelerometers, display, digital compasses, and CPUs.

3)    Reflectors   such as mirrors are used on AR devices to help human eyes to view virtual images.

4)    Animation tools such as  Maya   and  Blender  are the most common examples.

5)    The visuals on the screen can rendered by using an  HDMI   cable connected to a mobile phone or PC.

 

 

C) State ‘T’ for True or ‘F’ False:

1)    AR is interactive in real-time. TRUE 

2)    Augmented Reality and virtual Reality are the same. FALSE

3)    VR uses real-world setting.  FALSE

4)    AR users are controlled by the real world. TRUE

 

 

D) Short Ans type questions:

1) AR stand for?

Ans:  Augmented Reality

 

2) Write full form of VR.

Ans:  Virtual Reality

 

3) Name the components of AR.

Ans:   Hardware (Smartphones, HMD, sensors, etc.) and Software (computer vision, depth tracking, etc.)

 

4) What are the 3 uses of Virtual Reality?

Ans:  Entertainment, Training and Simulation, Healthcare

 

E) Long answer type questions:

 

1) What is Augmented Reality?

Ans:  Augmented Reality is the technology that overlays digital information, such as text, images, or 3D models, onto the real-world environment in real-time.  

 

2) What are the Applications and some examples of Augmented Reality?

Ans:  Applications include gaming, education, healthcare, and more. Examples: Pokemon Go, IKEA Place, Google Translate.

 

3) How is Augmented Reality different from Virtual Reality?

Ans:   Augmented Reality enhances the real-world environment with digital information, while Virtual Reality immerses the user in a completely digital environment, detached from the real world.

 

4) How does Virtual Reality work?

Ans: Virtual Reality works by creating a simulated environment through computer-generated images and sounds, usually experienced through a VR headset.  

 

5) Write short note on Virtual Reality.

Ans:    Virtual Reality is a computer-generated simulation that immerses users in a virtual environment, providing a realistic and interactive experience.

 

F) Guess who am I?

1) I am involves projecting generated simulations on AR headset lenses or other surfaces for viewing.

Ans: Augmented Reality (AR)

 

2) I am completely immerses the user in a digital world.

Ans: Virtual Reality (VR)

3) I am used on AR devices to help human eyes to view virtual images.

Ans: Reflectors

 

4) I am collect data about the user’s interaction with the app and virtual objects and send them for processing.

Ans: Sensors

 

 

G) Group Discussion:

1) Divide the class into four groups. Discuss the difference between Augmented Reality and Virtual Reality.

1.     Ans: Augmented Reality (AR):

• Definition: AR overlays digital information onto the real-world environment.
• Interaction: Enhances the real world with additional digital elements.
• Examples: Pokemon Go, IKEA Place.
• Practical Uses: Training simulations, navigation, education.
• Group Discussion Points: Discuss real-world applications and the impact on daily life.
1. Virtual Reality (VR):
• Definition: VR immerses the user in a completely digital environment.
• Interaction: Creates a simulated environment detached from the real world.
• Examples: VR gaming, virtual tours.
• Practical Uses: Training simulations, healthcare therapies.
• Group Discussion Points: Explore the potential of VR in various fields.
2. Comparison:
• Discuss the key differences: real-world augmentation vs. complete immersion.
• Explore potential future developments and advancements in AR and VR.
3. Integration:
• Discuss scenarios where AR and VR might be integrated for a more comprehensive experience.
• Brainstorm ideas for innovative applications combining both technologies.
