The document summarizes a new computer input device called the "Ring Mouse". It consists of an accelerometer-equipped ring that is worn on the finger. By moving the finger, the ring can sense movement and wirelessly transmit cursor movement data to a computer. It provides an intuitive interface without needing a mouse pad or flat surface. With third party software support, it could enable new applications that take advantage of direct input motion on the screen and revolutionize computer input technology. The basic technology uses time difference of arrival calculations to sense movement, similar to the Nintendo Wii remote.

4. Introduction
Ring mouse is the next generation of computer
interface. It is obviously very raw but if it were
mounted in a mouse shaped device and made wireless
it could be a winner.
Actually it would be very similar to
the Wiimote since the Wiimote uses accelerometers to
read controller movement and Bluetooth to transmit
that data to the controller.

"With a new interface like this, third party developers
could design new applications that would take
advantage of the intuitive connection between user
input and motion on the screen. This device could pave
the way for a new revolution in computer input
technology."

9. TDOA:
The basic principle behind the Magic Mouse
is called time difference of arrival (TDOA) .

11. “Ring Mouse” shows you a different
way of cursring around. Just strap it to
your finger; you can then cursor on any
surface, including your thumb. The kind of
handiness when using “ring mouse” is you
don’t have to get a mouse pad or find a flat
surface to use your mouse.

12. The three-dimensional mouse of the present invention thus has as
its primary advantage the availability of an additional analog
control input to the application software that it provides when
utilized in conjunction therewith. The user does not need to
control a separate device to achieve these third control parameter
existing technologies to easily and inexpensively achieve the third-
dimension input

13. In certain situations, pushing down on the
entire mouse could affect control over the normal
X-Y movements of the mouse. For these
situations it is proposed that an alternate
implementation be utilized in which the PPT is
included in the form of a non-moving "button"
on the side of the mouse

14. The design is simple and straightforward and can utilize
any of a number of existing technologies to easily and
inexpensively achieve the third-dimension input. Suitable
application programs utilizing the third-dimension may
be easily written to provide, even greater, user
"friendliness" for the already widely accepted mouse input
technology.
