Information displaying apparatus and information displaying method
First Claim
1. An information displaying apparatus comprising:
- a displaying unit configured to display first content on a display;
an audience state detecting unit configured to detect (i) a first audience state representing a physical state of an audience member positioned in front of the display at a first point in time, and (ii) a second audience state representing the physical state of the audience member positioned in front of the display at a second point in time after the first point in time;
an interest degree estimating unit configured to estimate (i) a first interest degree based on the first audience state detected by said audience state detecting unit, the first interest degree indicating a degree of interest of the audience member in the first content displayed on the display by said displaying unit at the first point in time, and (ii) a second interest degree based on the second audience state detected by said audience state detecting unit, the second interest degree indicating the degree of interest of the audience member in the first content displayed on the display by said displaying unit at the second point in time after the first point in time, and; and
a display control unit configured to (i) calculate a magnitude of a rate of change from the first interest degree to the second interest degree and (ii) cause said displaying unit to display second content with a clarity degree or an exposure degree of at least a part of the second content reduced below a predetermined clarity degree or a predetermined exposure degree when the magnitude of the rate of change from the first interest degree to the second interest degree is smaller than a first threshold.

Abstract
The present invention provides an information displaying apparatus which efficiently arouses an interest of the audience member to content to be displayed.
An information displaying apparatus (10) includes: a displaying unit (14) which displays first content on a display; an audience state detecting unit (11) which detects an audience state representing a physical state of an audience member positioned in front of the display; an interest degree estimating unit (12) which estimates an interest degree based on the audience state detected by the audience state detecting unit (11), the interest degree indicating a degree of interest of the audience member in the first content displayed on the display by the displaying unit (14); and a display control unit (13) which causes the displaying unit (14) to display second content with a clarity degree or an exposure degree of at least a part of the second content reduced below a predetermined clarity degree or a predetermined exposure degree when magnitude of a change rate of the interest degree estimated by the interest degree estimating unit (12) is smaller than a first threshold.

14. A method of displaying information, comprising:
-
displaying first content on a display; detecting (i) a first audience state representing a physical state of an audience member positioned in front of the display at a first point in time, and (ii) a second audience state representing a physical state of the audience member positioned in front of the display at a second point in time after the first point in time; estimating (i) a first interest degree based on the first audience state detected in said detecting, the first interest degree indicating a degree of interest of the audience member in the first content displayed on the display in said displaying the first content at the first point in time, and (ii) a second interest degree based on the second audience state detected in said detecting, the second interest degree indicating the degree of interest of the audience member in the first content displayed on the display in said displaying the first content at the second point in time after the first point in time; calculating a magnitude of a rate of change from the first interest degree to the second interest degree; and displaying second content with an area of a clarity degree or an area of an exposure degree of at least a part of the second content reduced below a predetermined clarity degree or a predetermined exposure degree when the magnitude of the rate of change from the first interest degree to the second interest degree is smaller than a first threshold. - View Dependent Claims (15)
