Abstract: An input interface device includes at least one processor. The processor performs control to cause, among light emitters, a first light emitter corresponding to a contact/proximity point detected by a detector to emit light with a luminous intensity higher than that of a remaining light emitter. The contact/proximity point is where an object is in contact with or in proximity to a detection surface. The processor further performs control, while the object is moving along the light emitters in a state in which the object is in contact with or in proximity to the detection surface, to gradually reduce a luminous intensity of, among the light emitters, a second light emitter corresponding to a point where the object being in contact with or in proximity to the detection surface once detected by the detector is no longer detected to put out the second light emitter in a predetermined time.

Abstract: Disclosed is an electronic device including: a display; a detector that detects contact or proximity between an operating body and a detection surface; multiple light emitters that are provided at a position corresponding to the detector, and cause the detection surface to emit light; and at least one processor. The processor performs control to link displaying regarding at least part of a content on the display with light emission of at least part of the light emitters.

Abstract: An electronic musical instrument includes an operation receiver that receives an input operation and a processor. The operation receiver includes a rotating wheel. The rotating wheel includes a first light emitter that emits colored light. The processor causes, upon the rotating wheel receiving an input operation, the first light emitter to change an emission color from a color at a start of the input operation to a color corresponding to a rotation angle of the rotating wheel having received the input operation.

Abstract: An electronic device includes: a memory including a data region that stores data; a display device; and at least one processor. At least one processor executes: first boot processing in which a boot time is constant irrespective of a usage state of data in the data region, first output processing of outputting information of a first pattern to the display device during execution of the first boot processing, second boot processing in which a boot time varies depending on a usage state of the data, and second output processing of outputting information of a second pattern to the display device until the second boot processing is completed.

Abstract: An electronic device includes multiple light transmissive panels, a plurality of light emitters, and a partition plate. The multiple light transmissive panels are provided so that light emitting surfaces of the panels are not parallel to each other. The plurality of light emitters includes a first light emitter and a second light emitter. The first light emitter and the second light emitter are provided corresponding to one of the panels and each radiate light to out of the electronic device through the one of the panels. The partition plate is erected between the first light emitter and the second light emitter so that the partition plate prevents the light of the first light emitter from being incident on a position on the one of the panels where the light of the second light emitter is incident.

Abstract: A display apparatus includes an image pickup section, a display section, an instruction section, a position specification section, a direction specification section, a specification section, and a reporting section. The image pickup section sequentially picks up an image. The display section displays the picked up image. The instruction section generates an instruction signal for marking an object included in the image. The position specification section specifies a position where the display apparatus exists. The direction specification section specifies a pickup direction by the image pickup section. The specification section specifies a position of the object relative to the position of the display apparatus based on the position of the display apparatus and the pickup direction in response to the instruction signal. The reporting section reports the position of the object.
