There is provided an image display apparatus that enables an intuitive operation even when a detection target is not able to be inserted into a first space in which a three-dimensional object is visually recognized. A position of a detection target is detected, and a display position of a pointer displayed by a display unit is moved on a basis of a position of the detection target that exists within a second space not overlapping the first space which is a space in which the three-dimensional object is displayed among the position of the detected detection target.

A multi-functional human interface device includes a control unit and a first multi-functional input button. The first multi-functional input button includes a cover unit configured to receive a touch input of a user's finger, an electrode unit including a transmitter and a receiver to form an electric field, an elastic unit configured to move from a first height to a second height when a first pressure is applied from the cover unit and configured to move back to the first height when the first pressure from the cover unit is released, and a switch unit configured to generate an electric signal representing an input of a predetermined letter.

A projection control device that controls a projection portion which projects an image to a projection surface includes a ray position detection portion that detects an irradiation position of a ray irradiated on the projection surface, and a specific image superimposition control portion that superimposes a predetermined specific image on a region corresponding to the irradiation position in the image. In a state where the specific image is superimposed on a first region corresponding to a first position detected by the ray position detection portion in the image, the specific image superimposition control portion, in a case where the irradiation position moves out of a predetermined range including the first position, moves the specific image to a region corresponding to the irradiation position that has moved, and in a case where the irradiation position moves within the range, continues superimposition of the specific image on the first region.

Provided are a spread spectrum clock generator and a spread spectrum clock generation method, a pulse pattern generator and a pulse pattern generation method, and an error rate measuring device and an error rate measuring method capable of improving usability when adjusting a waveform of a modulation signal during training. A setting screen 60 includes a 0-th frequency shift input unit 71 for arbitrarily setting a frequency shift of a waveform of a modulation signal in a plurality of time sections, a first frequency shift input unit 72, a second frequency shift input unit 73, a third frequency shift input unit 74, and a modulation selection unit 67 for switching a waveform pattern of the modulation signal from a first pattern to a second pattern.

Provided are a display device and an operating method therefor. The display device include a user input interface configured to receive a signal from a remote control device, a wireless communication interface configured to receive image data from an external device and control data of the external device, a display configured to output a screen of the external device by using the received image data, and a controller configured to control the display to change a pointer display mode of the remote control device based on the control data of the external device received while outputting the screen of the external device.

Methods, systems, and apparatus, including computer programs stored on computer-readable media, for displaying contextually relevant information, comprising receiving cursor data comprising a location of a cursor on an electronic display, and determining a screenshot of at least a portion of the electronic display. One or more proximate alphanumeric characters may be determined in at least a portion of the screenshot based on the location of the cursor, and at least one of the proximate alphanumeric characters may be matched with one or more terms from a predetermined list of terms. An information card may be caused to be displayed on the electronic display based on the location of the cursor, the information card corresponding to the one or more terms from the predetermined list of terms.

An e-paper display device including an e-paper display panel, a graphics library and a display controller is provided. The display controller is coupled to the e-paper display panel. The display controller is configured to receive a line segment input signal and call the graphics library, and then drive, using a set of signal waveforms, the e-paper display panel to display a line segment. The set of signal waveforms is generated according to the line segment input signal and the graphics library. The line segment includes at least one gray level. In addition, a method for driving an e-paper display device is also provided.

A control device controls sound of a plurality of speakers. The control device includes: a generation unit acquiring image data and generates display image data from the image data by using conversion processing using shape information indicating a shape of a display surface; a display controller displaying a display image on the display surface by using the display image data; a receiver causing a cursor to be superimposed and displayed on the display image and receives position designation related to the plurality of speakers on the display image from a user who has visually recognized the cursor; and an identification unit calculating a position of the cursor from the position designation by referring to a correspondence relationship between the image data before the conversion processing and the display image data after the conversion processing, and identifying the position of the cursor as a position related to the plurality of speakers.
