Abstract: A method, an electronic device, and a computer program product for displaying a virtual button are provided in the invention. The method includes the following steps. First, the virtual button is activated. Each interactive object displayed on a display frame of a touch screen is detected to obtain an object region occupied by each of the interactive objects, and an initial position of the virtual button on the display frame is obtained. Next, whether the initial position of the virtual button is located within the object region determined. If yes, the virtual button would be displayed at the initial position. If no, whether a non-object region satisfies a first predetermined condition is determined so as to accordingly display the virtual button at the initial position, a first designated position lies within the non-object region, or a second designated position lies within both of the object region and the non-object region.

Abstract: The present invention discloses a wearable electronic device having a plurality of trapezoid structures rotatably connected with one another. At least one inclined surface is formed on two ends of each trapezoid structure. When protruding sides of adjacent inclined surfaces of adjacent trapezoid structures abut against each other and sunken sides of the adjacent inclined surfaces of the adjacent trapezoid structures abut against each other, the plurality of trapezoid structures is formed in a ring shape. When the protruding sides and the sunken sides of the adjacent inclined surfaces of the adjacent trapezoid structures abut against each other, the plurality of trapezoid structures is formed in a straight shape.
