Tangible Interactions and Augmented Reality

1
Tangible Interactions and Augmented Reality

• Nirav Mehta
• Anne Marie Piper

2
Tangible Bits

• Foreground vs. background bits
• How do we make use of the way people perceive
  objects, motion, and changes?
• For purpose of presenting info
• Enhancing understanding
• Foreground grasp and manipulate physical objects
• Background ambient media in augmented space

3
Knowledge Based AR

• Knowledge based takes feedback from physical
  world
• Intent based user controls what they want to
  see
• AR overlays virtual on physical
• Powerful means of providing
• information
• Laser printer maintenance

4
Reinventing the Familiar

• Air Traffic Control is a high risk context
• Dont want to disturb the current system
• Make incremental changes
• Additional technology needs to be seamless
• AR can combine original tactile cues with
  additional virtual information

Rationales for Tangibles and AR

• Learning
• Efficiency
• Informational
• Feel good factor

7
Learning

• Is it easier to start with the physical device?
• Socialized to learn things in a physical realm
  first, then understand it virtually
• Ex learning math, abacus
• Reinforces understanding
• Takes advantage of both visual and tactile memory
  (Air Traffic Control)
• Mapping physical to virtual world
• Familiar to unfamiliar

8
Efficiency

• Is there a point at which physical devices might
  slow down interaction?
• Searchable campus map
• Can Tangibles and AR increase efficiency?
• Maintenance of a complex system
• Achieve shared understanding in group work
• Example Designers Outpost

9
Informational

• Adding to surroundings
• Present non-urgent info peripherally
• Examples stock orb, live wire
• User determines whether or not they want to pay
  attention to the additional information
• Can also direct users focus

10
Feel Good Factor

• Why bring back rich physical devices?
• More natural means of input?
• Ease understanding of virtual information?
• Physical objects provide distinct feedback
• Interactions with computers may become routine
  and feedback may become unnoticed after time
• Tendency to give more attention to human feedback
  than machine feedback

When is Physical Better?

• Rubiks cube on computer vs. physical?
• Similar examples?
