Augmenting
Reality with 3D Sound Sources
The sound component is still missing in current AR applications,
which combine live video and computer graphics to produce
real-time visual effects. AR could be a solution for many
problems in sound delivery.
Augmented Sound Reality allows the user to place and move
different sound sources in the real world. With AR technology,
the user is equipped with see-through displays and a simple
pen input device to place 3D sound sources in the real
world. The different sound sources are represented by
3D objects on the head-mounted display. 3D sound can be
directly integrated and tested in this AR environment.
The user can directly manipulate the 3D sound sources
and observe the results immediately. Another advantage
of ASR is low cost. This system requires only a PC, a
Web cam, and i-glasses.
Innovation
3D virtual sound sources for virtual and augmented realities.
Vision
Current AR applications do not allow direct manipulation
of sound sources. ASR is the first prototype that combines
sound and graphics in an AR environment and offers a wide
spectrum for further applications. Especially in the authoring
process for AR applications, it becomes difficult to place
the sound sources using traditional 2D/3D authoring tools.
Now, authors can place 3D sound sources in real 3D space,
and they have a more intuitive experience of how the audio
really sounds. In another application of this technology,
the user can place virtual furniture in a room. This application
will be combined with ASR, so that the user doesn't see
the newly established room, but can hear how the radio
or DVD player sounds.
