Abstract

A mobile phone is capable of displaying data of a website stored in a server through a browsing function. The mobile phone is also capable of detecting a line-of-sight of a user with utilizing an infrared light. In a case where the user is reading a website, a keyword is acquired from a content of the website based on the line-of-sight of the user. Thereafter, if a search result screen on a search site is displayed, a plurality of index information are listed such that the index information of the website related to an acquired keyword becomes a higher rank.

Claims

1. An information terminal having a display portion displaying information comprising one or more of text and an image, the information terminal comprising:

at least one processor that

detects a plurality of line-of-sights between a user and the display portion, and determines a gaze point of the user on the display portion based on each of the plurality of line-of-sights;

determines a plurality of keywords, at locations within the information being displayed on the display portion, that correspond to locations of the determined gaze points, wherein a fixed phrase is determined as the keyword when a determined gaze point is included within a displaying range of an image;

for each of the plurality of keywords, determines a number of times that the keyword is gazed upon, and calculates a weighing value for the keyword based on the number of times that the keyword is gazed upon; and

,

when search results are to be listed on the display portion, determines an order of the search results based on the respective weighing values of the plurality of keywords, and causes the display portion to list the search results in the order,

wherein one or more of the search results including an image is ordered higher than one or more of the search results not including an image when a determined gaze point is included within a displaying range of an image.

2. The information terminal according to claim 1, wherein the search results comprise a plurality of index information retrieved based on a search word.

3. The information terminal according to claim 2, wherein the search word is different than the plurality of keyword.

4. The information terminal according to claim 2, wherein each of the plurality of index information is associated with data, and wherein determining an order of the search results comprises ordering one or more of the plurality of indexes that are associated with data that includes at least one of the plurality of keywords higher than one or more of the plurality of indexes that are associated with data that does not include at least one of the plurality of keywords.

5. The information terminal according to claim 1, wherein the search results comprise a plurality of predicted words.

6. The information terminal according to claim 5, wherein determining an order of the search results comprises ordering one or more of the plurality of predicted words that include at least one of the plurality of keyword higher than one or more of the plurality of predicted words that do not include at least one of the plurality of keywords.

7. The information terminal according to claim 1, wherein the search results comprise a plurality of conversion candidates corresponding to one or more input characters.

8. The information terminal according to claim 7, wherein determining an order of the search results comprises ordering one or more of the plurality of conversion candidates that include at least one of the plurality of keywords higher than one or more of the plurality of conversion candidates that do not include at least one of the plurality of keywords.

9. The information terminal according to claim 1, wherein the search results are retrieved from a database, and the database is stored in a server.

10. The information terminal according to claim 1, wherein the at least one processor determines each keyword when a time period that the gaze point remains at the location corresponding to the location of the keyword exceeds a predetermined time period.

11. An information terminal having a display portion displaying information comprising one or more of text and an image, the information terminal comprising:

at least one processor that

detects a plurality of line-of-sights between a user and the display portion, and determines a gaze point of the user on the display portion based on each of the plurality of line-of-sights;

determines a plurality of keywords, at locations within the information being displayed on the display portion, that correspond to locations of the determined gaze points, wherein a fixed phrase is determined as the keyword when a determined gaze point is included within a displaying range of an image;

for each of the plurality of keywords, determines a time that the keyword is gazed upon, and calculates a weighing value for the keyword based on the time that the keyword is gazed upon; and

,

when search results are to be listed on the display portion, determines an order of the search results based on the respective weighing values of the plurality of keywords, and causes the display portion to list the search results in the order,

wherein one or more of the search results including an image is ordered higher than one or more of the search results not including an image when a determined gaze point is included within a displaying range of an image.

12. The information terminal according to claim 11, further comprising a memory, wherein the at least one processor further:

for each of the plurality of keywords, stores the keyword in association with its weighting value in the memory;

after a predetermined amount of time has passed, re-calculates the respective weighing value of each of the plurality of keywords such that the respective weighing values of the plurality of keywords decrease over time; and

deletes a keyword from the memory when the weighing value corresponding to the keyword becomes equal to or less than a threshold value.

13. A display controlling method in an information terminal having a display portion displaying information comprising one or more of text and an image, wherein the method comprises:

detecting a plurality of line-of-sights between a user and the display portion;

determining a gaze point of the user on the display portion based on each of the plurality of line-of-sights;

determining a plurality of keywords, at locations within the information being displayed on the display portion, that correspond to locations of the determined gaze points, wherein a fixed phrase is determined as the keyword when a determined gaze point is included within a displaying range of an image;

for each of the plurality of keywords, determining a number of times that the keyword is gazed upon, and calculating a weighing value for the keyword based on the number of times that the keyword is gazed upon; and

,

when search results are to be listed on the display portion, determining an order of the search results based on the respective weighing values of the plurality of keywords, and causing the display portion to list the search results in the order,

wherein one or more of the search results including an image is ordered higher than one or more of the search results not including an image when a determined gaze point is included within a displaying range of an image.
