Beam-Its - Virtual Sticky Notes in the Real World
We present
the concept, design, and implementation of Beam-Its, a virtual version
of sticky notes, which can be placed in the physical
environment. Beam-Its are created on a PDA and placed on objects or
surfaces in the environment, where they are currently displayed by a
steerable projector. Beam-Its can contain handwritten text and
sketches, just as physical Post-Its, but also photos and sound
recordings made on the PDA, thus extending the functionality of
physical Post-Its R. They can also appear or disappear depending on
context, which enables additional usage scenarios.
