Tangible Interactions and Augmented Reality

Explore the use of tangible interactions and augmented reality in presenting information, enhancing understanding, and combining physical objects with virtual information. Learn about knowledge-based AR, reinventing familiar systems, and the rationales for tangibles and AR in learning, efficiency, informational, and the "feel good" factor.

Presentation Transcript

  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 • Don’t 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

  5. Rationales for Tangibles and AR • Learning • Efficiency • Informational • “Feel good” factor

  6. 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

  7. 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: Designer’s Outpost

  8. 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 user’s focus

  9. “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

  10. When is Physical Better? • Rubik’s cube on computer vs. physical? • Similar examples?
