Simulation of real-world interaction mechanisms can provide a bridge into the computer realm for new and novice users. Some techniques may even be applicable for more advanced users, especially when the techniques are so familiar they are essentially transparent to the task.
For
example, the RealPhoneTM
provides a handset similar to those in the
real world. Clicking the handset causes it to come off-hook answering
the phone or placing a call. Obviously, a
handset isn't necessary on a computer-based phone - most computer
phones simply use a push button labeled
Dial
.
However, we found that many users intuitively understand the role
of the handset without needing any instructions or labels.
The RealPhone also provides an animated, slideout drawer
containing speed-dial numbers and other settings. Tests have shown
that users enjoy the interaction and appreciate the reduced clutter.
