Systems and methods for identifying spurious signals in capacitive touch sensors. In some examples, the technology may include a capacitive touch sensor having an input surface, a stylus configured to transmit a first electrical signal through its exterior surface based on a determination of an orientation of the stylus, and one or more processors configured to: identify a contact to a first area of the input surface based on one or more changes in electrical charge sensed in the first area, determine that the one or more changes in electrical charge sensed in the first area include the first electrical signal, and determine whether to identify the contact to the first area as spurious based on the determination that the one or more changes in electrical charge sensed in the first area include the first electrical signal.

Provided is a processing device for controlling input by an electronic pen. The electronic pen includes a side switch disposed on a side surface of the electronic pen and a device that obtains contact information indicating whether or not a pen tip of the electronic pen is in contact with a panel. The processing device includes a processor and a memory storing instructions which, when executed by the processor, cause the processing device to: obtain switch information indicating a depression state of the side switch, determine whether or not the pen tip is in contact with the panel based on the contact information, output the switch information when the pen tip is not determined to be in contact with the panel, and disable a value of the switch information when the pen tip is determined to be in contact with the panel.

A sensor controller, which is connected to sensor electrodes and detects positions of one or more active pens based on charge induced on the sensor electrodes, includes a processor and a memory. The memory stores instructions that, when executed by the processor, cause the sensor controller to: detect an approach of one of the one or more active pens using the sensor electrode; pair with the one of the one or more active pens with the approach of the one of the one or more active pens detected and update pairing state information indicative of a pairing state of each of the one or more active pens that is paired with the sensor controller; and transmit the pairing state information from the sensor electrodes to the one or more active pens via an uplink signal used as a reference for time synchronization.

In a stylus for a display device, the stylus includes: a bearing housing; a roller in the bearing housing; and a first actuator coupled to the bearing housing and configured to apply a pressure against the roller to modulate a friction between the stylus and the roller.

A handheld stylus for use with a display device may include a handheld body, a tip movably coupled to the body, and at least one capacitive sensor configured to detect movements of the tip relative to the body. The at least one capacitive sensor may comprise at least one first conductive element secured to or integral with the body, and at least one second conductive element secured to or integral with the movable tip.
