USER INTERFACE DEVICE AND INPUT METHOD
First Claim
1. A user interface device configured to estimate a user'"'"'s degree of interest in a plurality of objects displayed on a screen, for performing an input process on the basis of the user'"'"'s degree of interest, said user interface device comprising:
- a gaze direction detection unit configured to detect a gaze direction of the user;
a gaze duration calculation unit configured to calculate a gaze duration during which the gaze direction has remained on each of the plurality of objects;
an eye-attracting force calculation unit configured to calculate an eye-attracting force of each of the plurality of objects; and
a degree of interest estimation unit configured to estimate 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.

Abstract
Provided is a user interface device (10) that 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 (26). The device includes a gaze direction detection unit (11) that detects a gaze direction of the user; a gaze duration calculation unit (12) that calculates gaze duration during which the gaze direction has remained on each of the plurality of objects; an eye-attracting force calculation unit (13) that calculates eye-attracting force of each of the plurality of objects; and a degree of interest estimation unit (14) 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.

19. An input method to be performed by a computer for estimating a degree of interest of a user in a plurality of objects displayed on a screen, on the basis of the user'"'"'s degree of interest, comprising:
-
detecting a gaze direction of the user; calculating a time during which the gaze direction detected has remained on each of the plurality of objects, as gaze duration; calculating an eye-attracting force for each of the objects; and estimating 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. - View Dependent Claims (20)
