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.
