Joy-dial for providing input signals to a device
First Claim
1. A joy-dial for providing input signals to a device, said joy-dial having a first and a second x-axis input position, a first and a second y-axis input position, and a first and a second directional input position, a joy pad, an elastically deformable diaphragm located below the joy pad corresponding to each of the x-axis and y-axis inputs, a contact located below and associated with each of the diaphragms and arranged so that pressure applied to the joy pad at one of the x- or a y-axis input positions results in deformation of the corresponding diaphragm and closure of the associated contact, and wherein the joy-dial further includes a first and a second directional contact, said first and second directional contacts being arranged so that they are closed upon movement of the joy-dial in a first or a second direction respectively.

Abstract
The invention relates to a joy-dial for providing input signals to a device. The device would typically include mobile devices such as a portable digital assistant (PDA), hand phones and wireless handsets. With all of these devices it is important to maximise input possibility by the user, whilst minimising the size of the componentry. The joy-dial is rotatable so as to provide additional inputs
