XWand
The XWand is, or was, a research project by Andy Wilson of Microsoft.

It is a wireless sensor package that enables styles of natural interaction with intelligent environments. For example, a user may point the wand at a device and control it using simpe gestures.
Project details (last updated April 2004) are available from the project page at Microsoft Research

Questions raised (but not necessarily answered by this project) include:
- What kinds of interactions do users expect? Which are they willing to learn?
- Can the wand be used to contextualize automatic speech recognition?
- How to combine multiple sources of noisy information to arrive at a single interpretation?
- Can a single set of gestures span the majority of applications?
- Is the position of the wand really needed?
I am working on Visualisation solutions, i am looking for Wand. Is this ready for market.
This was a research project at Microsoft and I’m not sure it ever became a commercial product – there is an email address for the original Author at the project home page
