Abstract: A picture presentation system 1 presents a user U with a picture where a virtual image Di is created in a space in front of the user U. The picture presentation system 1 includes a hologram mirror 10 configured to reflect a picture composed of light of a specific wavelength at an angle different from an angle of incidence and transmit light other than the light of the specific wavelength, and a screen 20 configured to display the picture toward the hologram mirror. The hologram mirror 10, being placed opposite to the user U, reflects the picture from the screen 20 in such a way that the user U can visually recognize the virtual image Di of the picture at a position on the opposite side from the user U across the hologram mirror 10 (arrow AR1).

Abstract: A mobile terminal that prevents a display screen from finely blurring according to expansion and contraction of a flexible display. When a variation in a sensor value detected by a rotation angle sensor is greater than a range based on a predetermined threshold value, the image processing unit performs control for changing a display size of display information to be displayed on a flexible display. Thus, it is possible to absorb shaking based on a rewinding force of a mainspring in a storage unit and to prevent blurring of the display information.

Abstract: A small-sized head-mount type vision testing device, which is mounted on a testee's head, including: a display device that presents a visual target to an eyeball of the testee; a display optical system that guides light of the visual target presented on the device to the retina; an imaging device that images the eyeball; and an observation optical system that guides an image of the eyeball to the imaging device, and further including a mirror that reflects light of a specific wavelength and transmits the other light at a point closer to the eyeball side than the display device, wherein an optical axis from a pupil to the mirror in the display optical system and an optical axis from the pupil to the mirror in the observation optical system, coincide with each other, and the optical axes are bent through the mirror.

Abstract: A withdrawal amount calculation unit calculates a withdrawal amount of a display portion and transmits the withdrawal amount to a display control unit. In a case where a display width of the display portion based on the withdrawal amount exceeds a display threshold value, the display control unit causes the display portion to display second content together with first content. In this manner, in a case where the withdrawal amount is detected and the display width based on the withdrawal amount exceeds the threshold value, content (the second content) other than the first content is displayed. Therefore, it is possible to display a plurality of contents only when it is better to output the plurality of contents to the user according to a withdrawal operation of the user.

Abstract: A vision testing device and a vision testing program are capable of obtaining a correct test result while reducing an accumulation of fatigue added on one of the eyes of a testee, including: image displays that present a light for suppressing a dark adaptation for both eyes of a testee; and image displays that present a target for an eye (L, R, or both) of the testee so that the target is presented for one of the eyes before the vision testing for the other eye is ended.

Abstract: In a communication system, a PBX, a smartphone, and a communication adapter are connected. When detecting an event related to a call such as an incoming call and an outgoing call, the communication adapter transmits information on the event to the smartphone through BLE communication with the smartphone. The smartphone makes a notification of the occurrence of the event, based on the information on the event transmitted from the communication adapter. After the notification of the occurrence of the event, the communication adapter transmits an Invite command, “180” command, or the like to the PBX.

Abstract: A home screen display unit arranges and displays a plurality of content icons indicating a plurality of pieces of content in a first area in a content zone screen. If a specific content icon is focused on by the cursor and if a preset determination operation is performed, a content playback unit starts playback of the content indicated by the focused icon. If a specific content icon is focused on by the cursor, a related information acquiring unit acquires related information relating to the content that is indicated by the focused icon that is registered in an external device from the external device without starting playback of the content. A home screen display unit displays the acquired related information in a second area of the content zone screen and displays, if related information is updated, the updated related information in the second area so as to replace the related information displayed until that moment.
