An electronic device, in response to detecting a touch input on a touch-sensitive surface, determines an intensity of the touch input. In accordance with the intensity of the touch input on the touch-sensitive surface and one or more preselected intensity thresholds, the device determines an intensity stage of the touch input and one or more intensity-based progress values of the touch input, based on an intensity range associated with the determined intensity stage. The device sends touch information to a first software application stored by the electronic device, including the one or more intensity-based progress values of the touch input and information identifying the intensity stage of the touch input, and processes the touch input based on the one or more intensity-based progress values of the touch input and the intensity stage of the touch input.

An electronic device is disclosed and includes a display and at least one processor operatively connected with the display. The at least one processor is configured to, when an application is executed, display an execution window corresponding to the application on the display, display the execution window, as a first shape of execution window, on at least a portion of the display, in response to a background switch request for the application, identify a state of the application while displaying the first shape of execution window, and switch the first shape of execution window into a second shape of execution window according to the state of the application.

An input device includes: a touch device configured to receive a user operation; an actuator configured to apply a vibration corresponding to a drive voltage to the touch device; and a processor. The processor is configured to: apply a first voltage to the actuator to vibrate the touch device with a first vibration in response to a touch-down during a touch operation, the touch-down in which a pressing force of a predetermined value or more is detected from start of touch to the touch device; and apply a second voltage lower than the first voltage to the actuator to vibrate the touch device with a second vibration in response to a touch release during the touch operation, the touch release in which a pressing force of a value lower than the predetermined value after the touch-down is detected.

A method implemented by a transmission device to communicate with multiple reception devices that respectively share a drawing area with the transmission device is provided. The transmission device transmits to the multiple reception devices vector-data ink data representative of traces of input operation detected by an input sensor of the transmission device. The method includes: (a) an ink data generation step of generating fragmented data of a stroke object, wherein the stroke object contains multiple point objects to represent a trace formed by a pointer, the fragmented data being generated per defined unit T, and generating a drawing style object; (b) a message formation step of generating messages including the drawing style object and the fragmented data; and (c) a transmission step of transmitting the messages.
