1. A handheld device comprising:
- a housing;
an elongated rod including a tip at a first end and a compressible element at a second end, wherein the compressible element includes conductive material, and wherein the elongated rod is movable with respect to the housing;
a pyramid structure including at least three walls and an electrode on each of the at least three walls, wherein the pyramid structure is fixed or integrated with the housing, and wherein the compressible element is configured to be placed in the pyramid structure and to press against the electrodes based on a force vector applied on the tip; and
a circuit configured to;
apply signals on the compressible element or the electrodes;
detect outputs from the electrodes; and
provide pressure related information based on the outputs.

Abstract
A handheld device includes a housing, an elongated rod movable with respect to the housing, a pyramid structure and a circuit. The elongated rod includes a tip at a first end and a compressible element at a second end. The compressible element includes conductive material configured to press against the electrodes based on a force vector applied on the tip. The pyramid structure includes at least three walls and an electrode on each of the at least three walls and is fixed or integrated with the housing. The circuit transmit signals on the compressible element or the electrodes, detect outputs from the electrodes and provide pressure related information based on the outputs.

12. A method comprising:
-
providing a handheld device including a housing and an elongated rod that is movable with respect to the housing, wherein the elongated rod includes a tip at a first end and a compressible element at a second end, the compressible element including conductive material; detecting outputs from at least three electrodes, each electrode of the at least three electrodes positioned on a wall of a pyramid structure, the pyramid structure fixed to the housing, wherein the outputs detected are sensitive to movement of the elongated rod and pressing of the compressible material in the pyramid structure against the electrodes which are positioned on the walls; and reporting pressure related information based on the outputs to a computing device communicating with the handheld device or applying the pressure related information for adjusting operation of the handheld device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
