Abstract: A portable game machine with a display which also serves as a touch panel type input portion is comprised of means for detecting a contact between a finger of a player and a screen, means for computing a coordinate position of the finger on the screen, means for computing and determining the coordinate position where the object to be displayed on the display is displayed so as to separate a predetermined distance from the coordinate position of the finger and to create a gap between the object displayed on the display and a periphery of the finger contacted with the screen, and object display means for displaying the object at the computed and determined coordinate position on the display.

Abstract: A user interface processing apparatus is provided. A user interface element such as a virtual controller is displayed on a display screen. When an operation to the displayed user interface element is received from a player, the application is controlled in accordance with the received operation. A learning level of the player is determined in accordance with a control state of the application, such as utilization time of the application and the number of executions of a predetermined function in the application. The transparency is increased in accordance with the determined learning level. In a case where it is detected that an operation state of the user interface element continues for a certain period of time, transparency of the user interface element to increase is determined. The user interface element is displayed with the determined transparency.

Abstract: Spotlight information that contains at least coordinate information indicating a coordinate at which an object is positioned is generated in accordance with a selection operation for selecting the object. A spotlight screen, including a spotlight illuminating region for receiving an operation input and a darkened region for receiving a request to cancel the selection operation, is displayed in accordance with the generated spotlight information. The received selection operation is determined in a case where a selection of the spotlight illuminating region is received. A predetermined region having its center at a coordinate at which the object is positioned is determined as the spotlight illuminating region. A predetermined region including a coordinate on which an object, for which the selection operation is not received, exists is determined as the darkened region in a case where there is the object within the spotlight illuminating region.

Abstract: A user interface processing apparatus for controlling an application is provided. In the user interface processing apparatus, a touch on a display screen by means of a contact operation by a user on a touch panel is received. A touched position on the touch panel is detected when the touch on the display screen is received. The touched position is a position touched by the player on the display screen. A virtual controller is displayed at a predetermined position on the display screen corresponding to the detected touched position in a case where the touch on the display screen is received. An operation of the virtual controller displayed on the display screen is received from the player. The application is controlled in accordance with the operation received from the player.

Abstract: A portable computer is comprised of means for computing and determining whether a main body of the portable computer was rotated in a horizontal plane by predetermined degrees, means for determining that a request of change of dominant hand was inputted when the main body has rotated by the predetermined degrees, means for switching a dominant hand setting when the request of change of the dominant hand was inputted, means for reversing a game image and displaying the reversed image after switching the dominant hand setting, and means for switching a display position of a user interface element and displaying the switched one and for switching program for controlling the user interface element.
