Blood flow of a user can be measured using a sensor. Sensor data based on the measuring of the blood flow can be generated. Based on the sensor data, at least a first physiological biomarker of the blood flow measured by the sensor and at least a first morphological characteristic of the blood flow measured by the sensor can be determined. The user can be authenticated based, at least in part, on the first physiological biomarker and the first morphological characteristic.

Real time authentication based on blood flow parameters

In particular embodiments, an apparatus includes a single electrode configured to passively receive a charge displacement and a change in characteristics of electromagnetic signals in an environment. The apparatus further includes a touch sensor, coupled to the single electrode, configured to detect a first input based on the charge displacement, and a second input based on the change in characteristics of electromagnetic signals in the environment.

Interaction sensing

A user input on a panel can be realized by detecting, by the panel, at least a first electromagnetic signal output by a pen device and, responsive to detecting the first electromagnetic signal output by the pen device, initiating at least a first process of a plurality of processes based on detecting the first electromagnetic signal output by the pen device.

Pen device&#x2014;panel interaction based on electromagnetic signals output by the pen device

In particular embodiments, an apparatus includes an insulator coupled to one or more electrodes that are configured to passively sense charge displacement or a change in characteristics of electromagnetic signals in an environment.

In particular embodiments, a method includes receiving a signal from an electrode of a touch sensor that senses a charge displacement, based on the signal, in order to detect the contact or separation. The method further includes detecting a contact or separation input to the touch sensor.

The touch sensor is a touch sensor that senses changes in characteristics of the electromagnetic signal in an environment in order to detect the contact or the proximity.
