Abstract: An apparatus is disclosed for supplying input signals to a computer. A sensor having the form of a sphere has a touch sensitive surface for generating position data for touch events. The sensor includes orientation sensors that determine rotation with respect to the earth's magnetic and gravitational fields. Orientation data may be combined with position data to interpret the orientation of touch events on the surface with respect to the computer's display. Cursor movement or text may be generated from touch events. Preferably the sphere has a roughened surface that generates sound when touched. Position data is generated by processing signals from microphones under the sphere's surface.

Abstract: The position of a mechanical interaction in a sensor constructed from fabric is detected. A substantially constant electric current is established through elements of the fabric. A first electrical potential developed in a first plane is measured in response to such current. A second electrical potential developed in a second plane is also measured in response to the current. Then the measurements are processed to identify a position of the mechanical interaction. A calibration circuit is connected to provide an alternative route for current flow through the first plane and through the second plane.

Abstract: The present invention relates to a detector constructed from electrically conducting fabric and configured to present a varying electrical characteristic in response to a mechanical interaction. The detector comprises a first conducting layer (401) which is displaced from a second conducting layer (402) such that conduction between the layers results when the layers are mechanically forced together. In addition, the first of the layers has a plurality of lengths of conductive yarn and a plurality of lengths of non-conductive yarn machined therein, such that at least one length of conductive yarn is electrically isolated from another of the lengths of conductive yarn and the conducting yarns in the first of the layers are electrically grouped to define a plurality of identifiable rows. Each identifiable row has a respective electrical conductor; and define specific regions of the detector.

Abstract: A fabric-made position detector has a first fabric electrically conducting layer and a second fabric electrically conducting layer. The first electrically conducting layer has a first electrical contact and a second electrical contact and a second electrically conducting layer has a third electrically conducting contact and a fourth electrically conducting contact. Potential is applied across the first contact and the third contact to produce a first current and a potential is then applied across the second contact and the fourth contact to produce a second current. The first current is measured to produce a first current value and the second current is measured to produce a second current value. The first value and the second value are processed in combination to produce a property value indicating a property of the mechanical interaction.
