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.

Development

"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."

TDOA:

The basic principle behind the Magic Mouse is called time

difference of arrival (TDOA) .

“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.

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

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

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.
