A method for forming a crystal nucleus in a latent heat storage material contains a solvent and a dissolved substance. The solvent contains water as the main ingredient. The latent heat storage material retains latent heat in a supercooled state. The method includes: (a) separating out an anhydride of the dissolved substance by heating or cooling part of the latent heat storage material in the supercooled state; and (b) supplying a droplet comprising water to the anhydride, to terminate the supercooled state of the latent heat storage material, and make the latent heat storage material dissipate heat.

A user interface device estimates a user's degree of interest, for performing an input process on the basis of the user's degree of interest in a plurality of objects displayed on a screen. The device includes a gaze direction detection unit that detects a gaze direction of the user; a gaze duration calculation unit that calculates gaze duration during which the gaze direction has remained on each of the plurality of objects; an eye-attracting force calculation unit that calculates eye-attracting force of each of the plurality of objects; and a degree of interest estimation unit that estimates the user's degree of interest in each of the plurality of objects, such that the longer the gaze duration is the higher the degree of interest becomes, and that the smaller the eye-attracting force is the higher the degree of interest becomes.

User interface device and input method

Provided is a remote control command setting device capable of regulating some operations while being easy to handle for children. The device reconfigures a correspondence between an operation for an operation area having multiple operation buttons arranged therein and a control command for an electric device. The device includes an operation history holding unit () for accumulating operation history for the operation area, a control command setting unit () for reconfiguring an available control command on the basis of the operation history, and an operation area setting unit () for reconfiguring a sub-area in the operation area on the basis of the operation history and the available control command.
