1. A wearable biosignal interface, comprising:
- a motion sensor configured to obtain a first signal based on a motion of a target;
a biosignal sensor configured to be disposed on the target and obtain a second signal from the target; and
a determination controller configured to perform, in response to a magnitude of the first signal being less than or equal to a first threshold, a function of the wearable biosignal interface using a portion of the second signal corresponding to an interval during which the magnitude of the first signal is less than or equal to the first threshold.

Abstract
A wearable biosignal interface and operation method of the wearable biosignal interface is provided wherein the wearable biosignal interface may perceive a motion unintentionally performed by a user and ignore a biosignal obtained thereby and thus, improve accuracy of a bio-based determination of an intention of the user for operating a device.

15. An apparatus comprising:
-
a motion sensor configured to detect a movement signal corresponding to a movement of a target; a second sensor configured to detect a biological signal corresponding to a biological information of the target; and a controller configured to; determine an interval of stability in which a magnitude of the movement signal is less than or equal to a movement signal threshold, determine a portion of the biological signal detected in the interval of stability, and identify a command for controlling another device using the portion of the biological. - View Dependent Claims (16, 17, 18, 19)
