Abstract: A method of saccade-based positioning of a radial user interface includes performing operations while a first radial user interface is displayed on a display. The operations include (a) detecting a saccade movement based on eye-tracking data received from an eye-tracking system; (b) determining whether the saccade movement crosses a first region border corresponding to a first region of the first radial user interface; (c) determining a velocity of the saccade movement based on the eye-tracking data; and (d) dynamically determining a location for a subsequent radial user interface in response to the velocity and in response to determining that the saccade movement crosses the first region border. The method also includes displaying, on the display, the subsequent radial user interface at the location.

Abstract: A method for inputting gaze for a display and devices performing the same are disclosed. A method for inputting gaze for a display according to an example embodiment includes sensing gaze of a user and moving symbols displayed on both eyes of the user through the display, determining whether the both eyes move in a vergence manner based on the movements of the symbols to converge or diverge, and determining whether the gaze is directed to the symbols based on the determination result.

Abstract: Disclosed are an input method and apparatuses performing the input method. The input method includes selecting, in response to a gaze of a user, a keyboard corresponding to the gaze from a plurality of keyboards in a virtual reality and inputting, in response to a touch of the user, a key corresponding to the touch among a plurality of keys included in the selected keyboard.

Abstract: An electronic device is provided, including an input unit configured for a manipulation of the smart device, wherein the input unit includes a touch screen coupled with a display of the smart device, and assistant input means associated with the touch screen extending to a plurality of sides of the smart device or associated with touch sensors formed on the plurality of sides, and configured to detect a touch on the side, wherein the touch detected by at least one of the touch screen and the assistant input means is recognized as an input signal for the manipulation.
