Tactile feedback for capacitive sensors

摘要

A tactile feedback apparatus for a capacitive sensing device is comprised of a dielectric insulator having a surface. A finger receiving recess is defined in the surface. The finger receiving recess is configured for receiving a deflected portion of a finger. The finger receiving recess is comprised of a finger deflecting feature and a tactile feedback feature. The finger deflecting feature is coupled to the surface and structured such that a variety of finger sizes pressed into the finger receiving recess would deflect into a predictable and repeatable shape for affecting the capacitive sensing device in a substantially uniform manner. The tactile feedback element is coupled to the surface and disposed such that the tactile feedback element contacts the deflected portion of the finger to provide tactile feedback to the finger only when the finger is sufficiently deflected into the finger receiving recess to actuate the capacitive sensing device.

1. A tactile feedback apparatus for a capacitive sensing device, said tactile feedback apparatus comprising:
a dielectric insulator having a surface; and a finger receiving recess defined in said surface, said finger receiving recess configured for receiving a deflected portion of a finger, wherein a maximum interior cross-sectional measurement of said finger receiving recess is less than ten millimeters, said finger receiving recess comprising:
a finger deflecting feature coupled to said surface and structured such that a variety of finger sizes pressed into said finger receiving recess would deflect into a predictable and repeatable shape for affecting the capacitive sensing device in a substantially uniform manner; anda tactile feedback element coupled to said surface and disposed such that said tactile feedback element contacts said deflected portion of said finger to provide tactile feedback to said finger only when said finger is sufficiently deflected into said finger receiving recess to actuate said capacitive sensing device.
