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.
Claims20
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.

An operation method of a wearable biosignal interface, the method comprising:
- using a motion sensor to obtain a first signal based on a motion of a target;
- using a biosignal sensor disposed on the target to obtain a second signal;
- and
- performing, 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.
1 more element
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.
