Abstract

See full text

An input device comprising: a printed circuit board (PCB) comprising non-linear circuitry; resistive circuitry including a force-sensitive resistor (FSR) coupled to the PCB in parallel with the non-linear circuitry; and a hinge coupled to the PCB and the FSR configured to strain the FSR in response to a force applied to a tip of the input device. A stylus comprising: a housing; and stylus circuitry at least partially positioned within the housing, wherein the stylus circuitry comprises: body circuitry; a front tip interface; and front tip stylus circuitry positioned between and electrically coupled to the body circuitry and the front tip interface, wherein the front tip stylus circuitry comprises non-linear circuitry in parallel with physical interaction characteristic (PIC) circuitry; wherein the front tip stylus circuitry is operative to provide a non-linear load between the body circuitry and the front tip interface when the stylus is stimulated by an external stimulation; wherein the non-linear load is operative to provide a stylus electric field that is detectable by an electronic device when the front tip interface of the stylus is positioned adjacent an input surface of the electronic device; and wherein a resistance of the PIC circuitry is adjustable based on a force applied to the tip interface or based on a tilt angle of the stylus. An electronic device comprising: a plurality of first electrodes; a plurality of second electrodes; stimulation and sensing circuitry configured to transmit signals on the plurality of first electrodes and sense receive signals on the plurality of second electrodes; and processing circuitry configured to: extract, from the sensed receive signals, data indicative of a non-linear response to the transmit signals; estimate a position of an accessory on a surface of the electronic device based on the extracted data; and estimate a force applied to the accessory in contact with the surface of the electronic device or a tilt angle of the accessory relative to the surface of the electronic device based on the extracted data.
