A signal observation device includes: an observation unit that observes a volume of a target signal by using compressed sensing; a filter having a plurality of elements that are arranged in a matrix and that are capable of individually restricting the volume of the target signal to be transmitted to the observation unit; and a control unit that causes the observation unit to observe the volume of the target signal transmitted via the filter by using first control for controlling the elements of the filter on the basis of a first observation matrix in which values of matrix elements are predetermined and that causes the observation unit to observe the volume of the target signal transmitted via the filter using second control for controlling the elements of the filter on the basis of a second observation matrix in which values of matrix elements are based on random numbers. The control unit causes the observation unit to observe the volume of the target signal plural times by selectively using the first control and the second control.

A controller determines whether a language of an object in display data including the object and a coordinate of a rendering reference point of the object is a right-to-left writing language, and upon determining that the language of the object is the right-to-left writing language, determines an upper-right corner of a display screen of a display panel as a reference point, determines a position of the rendering reference point of the object on the display screen based on the determined reference point and the coordinate of the rendering reference point of the object included in the display data, and drives the display panel to display the object on the display screen based on the determined position of the rendering reference point on the display screen.

A method for sorting objects includes capturing characteristic data from a plurality of objects and creating a plurality of feature points in a feature space based on the characteristic data. The method also includes grouping the plurality of objects using spectral methods into one or more distinct groups according to the plurality of feature points.

A method of connecting graphical objects on a display includes associating a first portion of a connector with a first plane such that the first portion of the connector tends to remain in the first plane. The method includes receiving user input that manipulates a location of a first end terminal of the connector and/or a second end terminal of the connector. The method includes determining a first minimum number of elbows in the connector when the first portion of the connector is to remain routed in the first plane the manipulation. The method includes determining a second minimum number of elbows included in the connector when the connector does not remain routed in the first plane the manipulation. The method includes routing the first portion in the first plane unless the first minimum number of elbows is greater than the second minimum number of elbows.

A beacon device is a mobile object having an AR marker provided on its surface which indicates an existing position of the beacon device in actual space and transmits a beacon signal including a beacon ID. A user communication device, which is a mobile object equipped with an imaging function, identifies the position of the beacon device by recognizing the AR marker in a live view image, receives the beacon signal transmitted from the beacon device, transmits the beacon ID to a server device and controls to display an object corresponding to the beacon ID transmitted from the server device at the identified position of the beacon device in the live view image. The server device reads out the object corresponding to the beacon ID transmitted from the user communication device from a character data file group and transmits that data to the user communication device.

A character string display method includes: acquiring character string data, the character string data being data corresponding to a to-be-displayed character string, and the character string including at least one character; analyzing the character string data to generate an analysis result, the analysis result including number of digit information related to the character string and digit sequence information of each character; and displaying, digit by digit according to the digit sequence information and the number of digit information, a picture set corresponding to each character, the picture set including at least one picture.
