Abstract: A movement sound generation system (1) generates a movement sound when a moving body moves on a predetermined movement surface in a virtual space. A sound volume of the movement sound is decided based on a mass of the moving body in the virtual space. A sound quality of the movement sound is decided based on material information of a ground contacting portion of the moving body which contacts a movement surface in the virtual space, and on material information of the movement surface contacted by the ground contacting portion of the moving body. A sound production timing of the movement sound is decided based on a timing at which the ground contacting portion of the moving body contacts the movement surface. The movement sound of the moving body is played in the virtual space, with a sound volume, with a sound quality, and at a sound production timing.

Abstract: An advertisement display system 1 acquires coordinates of the avatar and a size of the avatar in the virtual reality space and calculates a movement speed of the avatar by dividing a coordinate change amount per unit time of the avatar in the virtual reality space by a reference amount in accordance with the size of the avatar. In addition, the system 1 determines whether a point of view of the avatar in the virtual reality space is set to a first-person point of view or a third-person point of view. Furthermore, the system 1 performs control to differentiate, when an avatar is moving in the virtual reality space, a position where advertising is to be displayed in the virtual reality space with respect to the user operating the avatar in accordance with the movement speed of the avatar and the point of view of the avatar.

Abstract: An audio content distribution system includes a server device and a user terminal. The server device includes an audio-data acquisition unit that acquires audio data from a distribution source, an audio-content-data generation unit that adds, to the audio data, acoustic-effect setting information indicating whether to add echo and/or attenuation of sound in a virtual reality space, and generates audio content data, and an audio-content-data distribution unit that distributes the audio content data to a user terminal of a user who operates an avatar in the virtual reality space. The user terminal includes an audio-content-data receiving unit that receives the audio content data from the server device, and an audio-data output-control unit that outputs the audio data stored in the audio content data with an acoustic effect according to the acoustic-effect setting information.

Abstract: An advertising display system includes: an advertising display unit which displays advertising on an avatar operated by a user in a virtual reality space; a contact information acquiring unit which acquires information on contact times of the avatar in the virtual reality space with other avatars operated by other users and the number of the other avatars; and an advertising fee calculating unit which calculates an advertising fee to be applied to each of the user and the other users based on the information on the contact times and the number of other avatars acquired by the contact information acquiring unit.

Abstract: Herein disclosed is a mobile communication apparatus, comprising: a body provided with a liquid crystal screen (5) having image data or character data displayed thereon, and an operating unit (6) for selectively performing operations, the body being divided into first and second housings (2 and 3) along a lateral direction perpendicular to a rotation axis; rotating means (4) for connecting the liquid crystal screen (5) with the operating unit (6) with the liquid crystal screen (5) with the operating unit (6) being rotatable with respect to each other around the rotation axis extending in the longitudinal direction of the liquid crystal screen (5) with the operating unit (6); a system control unit (21) for selectively setting predetermined operation modes in response to the rotation positions of the liquid crystal screen (5) with the operating unit (6) assumed when the liquid crystal screen (5) with the operating unit (6) are rotated with respect to each other through the rotating means (4).

Abstract: While an attitude of a housing and an attitude change thereof are employed so as to operate an application, an input unit capable of giving a top priority to the application is provided at a predetermined position of the housing so as to provide a portable terminal having a superior operability. The portable terminal 10 includes: an attitude detecting section 16 which detects one of an attitude and an attitude change of the housing 11; a control unit 17 which displays an image of an application on a display unit 13 based upon information acquired from a communication unit 14; and an output unit 18 capable of externally outputting image data and sound data of the application. In the portable terminal 10, the control unit 17 controls the application based upon the detection value obtained from the attitude detecting section 16.

Abstract: A cellular phone device is provided that improves the usability for the user when photographing a self-portrait while protecting an imaging unit from being soiled and damaged, by covering imaging unit with the following structure. That is, the phone device has a first casing, a second casing, and a third casing. One side of the first casing rotatably supports the second casing, and the other side of the first casing slidably supports the third casing. The first casing is loaded with the imaging unit, and the imaging unit is contained in the third casing when the third casing is slid along the first casing and partially overlaps with the first casing.
