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.

Abstract: A wearable device may obtain an image, while a screen is displayed, using a camera. The wearable device may identify a visual object corresponding to an external object from the image. The wearable device may display, at a first location of a portion of the visual object corresponding to a portion of the external object farther than a reference distance from a second surface, a pointer on the screen. The wearable device may recognize the external object contacted on the second surface according to movement from outside the reference distance, as a touch input at a second location identified based on a path of the movement and the first location, and provide feedback with respect to the touch input.

Abstract: An electronic device is provided. The electronic device obtains current spatial information on a physical space where a user is positioned using a sensor, generates a greater number of virtual objects than the number of unavailable authentication objects based on at least one authentication object among a plurality of authentication objects being unavailable in the current spatial information, outputs the generated virtual objects to a plurality of positions including a physical position of an unavailable authentication object, and determines that authentication is successful based on a user input that selects a generated virtual object and an available authentication object as a registered sequence.

Abstract: According to an embodiment, a wearable device may display, based on contact on a second surface identified using a touch sensor, a visual object indicating a first position of the touch input on the second surface in a screen through a display. The wearable device may identify, in response to the touch input, a second position in the screen of a gaze identified based on an image obtained through a camera exposed outside at a portion of a first surface. The wearable device may provide, in response to the second position identified within a specified distance from the first position of the visual object, feedback with respect to the touch input. The wearable device may cease to provide the feedback in response to the second position identified outside from the first position by the specified distance.
