Apple has filed for a new patent application, which surfaced this morning in the United States Patent & Trademark Office's (USPTO) database.
It reveals that the Cupertino firm is seeking to add pressure sensing capability to the iPhone's Touch ID button while hinting at the possibility of enabling 3D Touch-like functionality by way of applying various degrees of pressure to the Home button.
Titled “Force-sensitive fingerprint sensing input,” the invention describes adding a resistive element having a mechanically resistive force to the Touch ID button—such as an elastomeric material, spring or similar component—which would then be able to measure the depression.
