Patent ID: 8638306

Claim:
An apparatus comprising: a corner-type conductive pad to enable detection of an additional capacitance imparted to the corner-type conductive by the close proximity of a tip of a digit to the corner-type conductive pad, wherein the corner-type conductive pad comprises: a central region; a first tooth extending in a first direction outward from the central region of the corner-type conductive pad; and a second tooth extending in a second direction outward from the central region of the corner-type conductive pad, wherein the first and second directions are not in line and form an angle therebetween with the central region of the corner-type conductive pad located at the corner formed at the angle; a first conductive pad adjacent to the corner-type conductive pad to enable detection of an additional capacitance imparted to the first conductive pad by the close proximity of a tip of a digit to the first conductive pad, wherein the first conductive pad comprises: a central region; and a third tooth extending outward from the central region of the first conductive pad in a direction parallel to the first direction in which the first tooth extends such that the first and third teeth extend alongside each other such that they are enmeshed and form a first slider control between the corner-type conductive pad and the first conductive pad that extends in the first direction from the central region of the corner-type conductive pad; and a second conductive pad adjacent to the corner-type conductive pad to enable detection of an additional capacitance imparted to the second conductive pad by the close proximity of a tip of a digit to the second conductive pad, wherein the second conductive pad comprises: a central region; and a fourth tooth extending outward from the central region of the second conductive pad in a direction parallel to the second direction in which the second tooth extends such that the second and fourth teeth extend alongside each other such that they are enmeshed and form a second slider control between the corner-type conductive pad and the second conductive pad that extends in the second direction from the central region of the corner-type conductive pad such that a series of slider controls is formed having a corner where the first and second sliders meet at the central region of the corner-type conductive pad and at the angle formed between the first and second directions.
