Abstract: A stereoscopic image display device includes a display device, a camera that detects the position of the user's viewpoint looking at this display device, and a rotation device that rotates the display device around a rotation axis passing through its display surface. This rotation device rotates the display device in synchronization with the movement of the user's viewpoint position so that the direction of the user's viewpoint as seen from the display surface does not change. A three-dimensional object defined in a world coordinate system that remains stationary relative to the real world is displayed on the display device, and when the user's viewpoint moves, an image of the object as seen from the direction of the user's viewpoint is displayed on the display device.

Abstract: An aerial image display device is provided which can be folded into a small size and freely carried. The aerial image display device includes a display substrate displaying a contactless interface, an optical plate connected to the display substrate by a hinge member, and a support structure capable of fixing the display substrate and the optical plate at a predetermined angle. When the contactless interface is displayed on the display substrate with the display substrate and the optical plate being fixed at the predetermined angle, the contactless interface is displayed as an aerial image via the optical plate in air on the opposite side of the optical plate. The display substrate, the optical plate and the support structure can be stacked on each other and folded into a plane.

Abstract: A new input method for computer-executed programs using AI technology. The program is executed on a computer equipped with an imaging device, which captures the user's facial expressions. In the computer, a facial expression recognition system is implemented that recognizes the expressions captured by the imaging device. The computer-executed program then behaves differently depending on facial expression of the user.

Abstract: A game program capable of making maximum use of the characteristics of an aerial image display device including an aerial imaging system that projects an aerial image in the air, and a motion sensor that detects the motion of a hand of a user in the vicinity of the aerial image projected by the aerial imaging system. The game program controls the aerial imaging system to project an operation target in the air as an aerial image, and move the operation target projected by the aerial imaging system in response to the motion of the user's hand relative to the operation target detected by the motion sensor. The influence of gravity exerted on the operation target is reflected in the motion of the operation target.

Abstract: [Problem] To provide an access control device that controls access to operation means such as switches and push buttons. [Abstract] The access control device covers the operation means and prevents access to this means. This access control device is equipped with an authentication device, and if a user is successfully authenticated by this authentication device, access to the operation means is allowed to this user and the operation means can be operated. For example, this operation means is a push button, and the access control device has another push button superimposed on this push button and controls access to the push button as an operation means by controlling an engagement means that engages this other push button.

Abstract: A mobile terminal booth with a sound masking function includes a sound absorbing panel which partitions a space as viewed from the above to provide a place where a user of a mobile terminal can have a telephone conversation; a speaker provided to emit sounds to an outside of the mobile terminal booth; and a masking sound generation unit provided to emit a masking sound through the speaker. The harsh-sounding high frequency components of the masking sound are attenuated so that the masking sound gives less uncomfortable feeling to persons surrounding the mobile terminal booth. This masking sound is generated by attenuating a high frequency component of a raw sound material including a natural sound.

Abstract: In each page of a calendar or a notebook in which a rectangle paper is folded in eight with one side thereof divided into four equal parts and the other side thereof divided into two equal parts and each of front and rear regions of the rectangle paper divided into equal parts by folded lines serves as a page, an identifier which enables specification of the position of the page in the whole rectangle paper is printed. The identifier includes, for example, a combination of alphabets, numerals, and colors. In another embodiment, the identifier is an icon printed at a corner of each page. The icon has a high density portion, and the position of the page with respect to the whole rectangle paper is expressed as the position of the high density portion with respect to the whole icon.

Abstract: A user can confirm the congestion degree of a congestion confirmation area at the present moment by a congestion confirmation system which includes mobile communication devices and a congestion confirmation server. The mobile communication device periodically detects and transmits the current location information to the congestion confirmation server. Receiving the current location information, the congestion confirmation server stores the current location information in a database in association with a current time. The mobile communication device sends a congestion confirmation request designating one of the congestion confirmation areas. In response to this request, the congestion confirmation server refers to the database and transmits the location information of mobile communication devices currently located in the congestion confirmation area as designated.
