Abstract: Setting of a search condition is facilitated. A communication terminal initially displays a plurality of search panels including a search panel P1, which is an image corresponding to a search target in a certain category. Thereafter, upon a user selecting one of the search panel (here, P1), the communication terminal displays search panels P11 to P16, which are images corresponding to search targets in sub-categories of the category of the search panel P1. The user can change the search condition by moving one of the search panels P11 to P16.

Abstract: A user interface device includes: a detection unit that detects an inputting action to select a displayed object corresponding to a subject; and a generation unit that generates a query based on an inputting action detected by the detection unit, wherein the generation unit generates a query for a combination of a plurality of subjects upon detection of an inputting action to select a plurality of displayed objects corresponding to a plurality of subjects by a predetermined algorithm.

Abstract: A user interface device includes: a first display controller that displays a first object corresponding to a first subject and a second object corresponding to a second subject; a detection unit that detects an input instructing a change of an arrangement of the first and second objects; and a second display controller that displays a result of a search relating to the first and second subjects in response to an instruction detected by the detection unit, the result depending on the change of the arrangement.
