According to an aspect of the present inventive concept there is provided a method for eye tracking, comprising: capturing a sequence of digital images of an eye of a user; outputting data including said sequence of images to an image processing unit; processing said data by the image processing unit to determine a sequence of positions of the eye, each position being indicative of a gaze direction, acquiring biosignal data representing an activity of the eye; and in response to detecting closing of the eye based on the acquired biosignal data, pausing at least one of said capturing, said outputting and said processing. A system for implementing the method is also disclosed.

A system for hand gesture detection is provided, comprising: a wrist wear adapted to be worn about a wrist of a user of the system and including a set of skin electrodes adapted to face the wrist; an impedance measurement circuit adapted to measure at least a first impedance in a first portion of the wrist and a second impedance in a second portion of the wrist which second portion is circumferentially displaced in relation to said first portion, wherein the first impedance is measured via a first electrode group including four skin electrodes of said set of skin electrodes and the second impedance is measured via a second electrode group including four skin electrodes of said set of skin electrodes, and a processing circuit adapted to detect a hand gesture of the user based on the first and the second impedance measured by the impedance measurement circuit.

System for hand gesture detection

An electronic system for estimating a subject's blood pressure, comprising a feature extraction module configured for receiving a subject's photoplethysmogram signal, detecting a plurality of signal characteristic points on the received photoplethysmogram signal, calculating a plurality of distances in both time and amplitude between any two of the detected photoplethysmogram signal characteristic points, and providing a feature information signal comprising information about the calculated distances; and a blood pressure calculation module configured for receiving the photoplethysmogram signal, the feature information signal and anthropometric characteristics of the subject, and calculating systolic, diastolic and continuous mean blood pressure values of the subject.
