A piano system with key assisted user input may include one or more execution devices, one or more sensors, at least one signal processing circuit, a processor and a display. The one or more sensors may be configured to detect a signal indicating a status change of at least one of the one or more execution devices. The at least one signal processing circuit may be configured to generate a control signal for controlling an input of a computer device in response to the signal detected by the one or more sensors. The processor may be configured to process the control signal to determine content to be displayed on a user interface. The display may be configured to display the determined content on the user interface.
