The thrilling potential of MPAR

Pranav Mistry presents several ideas about human interaction with the physical world using Mobile Projective Augmented Reality (MPAR). He will make all of his work opensource, which will enable any one to build new interactive experience. See the video of his talk at TED India.

History of Mobile Augmented Reality


This web page summarizes the major milestones in mobile Augmented Reality since 1968. The list was compiled by the member of the Christian Doppler Laboratory for Handheld Augmented Reality for the ISMAR society.

10 Best Computer Interfaces

Here is a list of best computer interfaces given at Technology Review.
  • The Command Line
  • The Mouse
  • The Touchpad
  • The Multitouch Screen
  • Gesture Sensing
  • Force Feedback
  • Voice Recognition
  • Augmented Reality
  • Spatial Interfaces
  • Brain-Computer Interfaces

Although it appears that Command Line is a history as far as ordinary users are concerned. However, it is the most popular and the best user interfaces with in programmers/developers community, and is not likely to be replaced.

The 41 years old technology, Mouse is perhaps the most used interfaces device along with the keyboard. However, touch screens are now replacing this. Already, a lot of mobile phones are available in the consumer marker with touch screen.

However, the future user interfaces will be based on Gesture recognition, Voice recognition and Augmented Reality (including Spatial). Thus, traditional Screen-Keyboard-Mouse interfaces will be replaced with Camera-Projector-Microphone-Motion Sensors interfaces. The MPAR will be a revolution in Human Computer Interaction, and is beginning to happen now.

Towards Natural Features Tracking

The fiducial markers for AR applications provide robust tracking capabilities. However, it is more desirable to use natural features in the scene to estimate 6 DoF pose of the camera. The Studierstube Team at Graz University of Technology have demonstrated robust Natural Feature Tracking (NFT) for known planar surfaces. They use modified versions (for hand held devices) of SIFT and FERNS to compute and match features in the scene.
