Lecture 7 - AR Devices and Experiances

Question 1

What is AR?

Answer 1

Adding virtual sensations to the real environment. Towards the real side on the continuum.

Question 2

AR Experiances?

Answer 2

• Handheld AR
• Overlay AR
• Immersive AR
• Auditory AR

Question 3

Advantages and disadvantages of Handheld (e.g. phone) AR Experiances?

Answer 3

+:
- we already have them with us
- familiar usage
- can be put away
- can be taken anywhere (mobile)

-:
- limited viewport (scren can only be so big) , which leads to limited immersion
- restrictive and not readlily available
- 6DOF not commonly integrated and still under development
- potentially limited input as one hand will need to hold the device

Question 4

What is Overlay AR?

Answer 4

Placing content in front of users’ vision.

Question 5

Advantages and disadvantages of overlay AR?

Answer 5

+:
- unrestrictive
- readily available
- minimal hardware
- requires 0DOF or 3DOF maximum

-:
- limited interaction possible
- occludes rather than integrates
- very limited immersion
- egocentric only

Question 6

Advantages and disadvantages of immersive AR?

Answer 6

+:
- unrestrictive
- readily available
- Perspective-dependent rendering
- immersive and integrated
- egocentric and exocentric

-:
- greater technical demands (with exocentric especially)
- bulkier and less fashionable (development in this area)
- expensive

Question 7

Advantages and Disadvantages of auditory AR?

Answer 7

+:
- unrestrictive and readily available
- minimal hardware necessary (only speakers)

-:
- limited discoverability
- limited interaction possible

Question 8

What is auditory AR?

Answer 8

Augmented reality with sound e.g. pass through to the environment (ambient sound)

Question 9

Hardware influences interaction design, content placement for mixed reality.

Answer 9

Hardware influences interaction design, content placement for mixed reality.
