Abstract: An electronic device includes a sensor and a processor. The processor identifies whether a characteristic value measured from the sensor while acquiring a first image including a user's eye satisfies a designated condition. When the characteristic value satisfies the designated condition, the processor identifies a pupil position in the first image using a first scheme of extracting a feature point, based on matching with a designated pattern, acquires a second image including the user's eye, and identifies an amount of change in the second image with reference to the first image. When the amount of change in the second image is greater than or equal to a designated level, the processor calculates accuracy of the first scheme, and according to the calculated accuracy, identifies a pupil position in the second image using the first scheme, or a second scheme of extracting a feature point based on a trained network.

A third device that has not received the first signal emitted during the first time period and has received the second signal emitted during the second time period is identified. A user interface element based on the identifying the second device and the identifying the third device is generated, for output at the first device.

Abstract: Methods were formulated and applied to create and use a wearable hand interface device that is physically and digitally sculpted to accommodate the geometry of the human palm in a resting position while requiring minimal movement on behalf of the user. Comfortable harnessing material spans over the top of the hand. Structures which may be rigid or adjustable place input contact surfaces directly underneath and slightly above each fingertip of a user so that only a slight twitch of the fingers is needed to operate the device The precisely sculpted palm receiving surface and placement of contact surfaces in the natural curl path of the fingers ensures the hand does not move around during use. Refreshable braille cells may be mounted at the user's fingertips if desired. The nature of this device allows its user to activate sensor switches in a wide range of hand positions.
