Abstract

A head- or face-mounted image display device includes an environmental information acquisition unit that acquires environmental information, a state information acquisition unit that acquires state information, a guidance information generation unit that generates guidance information for guidance into a state in which the influence of environment is reduced or increased based on at least one piece of environmental information acquired for each state, and a provision unit that provides the guidance information.

First claim

What is claimed is:

1. An image display device, comprising:
one or more processors configured to:
acquire, from a set of sensors, a plurality of instances of state information of a body of the image display device, wherein the state information includes at least one of position or posture;
acquire, from another set of sensors, environmental information for each acquired instance of the state information, wherein the acquired environmental information corresponds to one or more environmental factors that have an influence on at least one of the image display device or a user of the image display device;
determine based on acquisition of the environmental information a determined number of times, a direction in which the influence of the one or more environment factors on the at least one of the image display device or the user is one of reduced or increased based on the acquired environmental information and the state information, wherein the influence is increased based on the one or more environmental factors having a good influence, and reduced based on the one or more environmental factors having an adverse influence;
generate guidance information based on the determined direction for guiding the at least one of the image display device or the user into a subsequent state; and
output the generated guidance information to a display configured to display the generated guidance information in a superimposed manner on a real-time visual field of the user.

2. The image display device according to claim 1 ,
wherein the environmental information relates to at least one of the one or more environmental factors that include: electromagnetic waves, heat rays, radiation, carbon monoxide, carbon dioxide, oxygen, nitrogen oxide, nitrogen compounds, hydrocarbons, particulate matter, photochemical smog, pollen, house dust, and negative ions to which the at least one of the image display device or the user is exposed.

3. The image display device according to claim 1 ,
wherein the one or more processors are further configured to generate the guidance information for guidance into the subsequent state in which at least one of the one or more environmental factors that have the adverse influence on the at least one of the image display device or the user is reduced, or the guidance information for guidance into the subsequent state in which at least one of the one or more environmental factors that have the good influence on the at least one of the image display device or the user is increased.

4. The image display device according to claim 1 ,
wherein the one or more processors are further configured to output the guidance information on the display as an image.

5. The image display device according to claim 4 ,
wherein the one or more processors are further configured to output the guidance information on the display in a superimposed manner on an image of the visual field of the user with the image display device mounted on a head or a face of the user.

6. The image display device according to claim 5 ,
wherein the one or more processors are further configured to output, on the display in a superimposed manner on the image of the visual field of the user, the guidance information that indicates the direction in which the influence of environment is reduced or increased.

7. The image display device according to claim 1 ,
wherein the one or more processors are further configured to acquire current state information related to a current position of the image display device and a current posture of the user at a current time,
wherein the one or more processors are further configured to acquire the environmental information related to the at least one of the image display device or the user based on a change in the state information, and
wherein the one or more processors are further configured to generate the guidance information based on the environmental information acquired for a determined time up to the current time.

8. The image display device according to claim 1 ,
wherein the one or more processors are further configured to acquire the state information related to a current position of the image display device and a current posture of the user, and
wherein the one or more processors are further configured to generate the guidance information with respect to the current position or the current posture, based on the environmental information acquired by the one or more processors in a different position or in a different posture.

9. The image display device according to claim 1 ,
wherein the one or more processors are further configured to acquire state information related to a current position of the image display device, a current posture of the user, and a temperature, and
wherein the one or more processors are further configured to generate the guidance information with respect to the current position or the current posture, based on the environmental information acquired by the one or more processors in a different position or in a different posture or at a different temperature.

10. The image display device according to claim 1 ,
wherein the one or more processors are further configured to:
acquire current state information related to a current position of the image display device and a current posture of the user within a determined period of time,
acquire the environmental information related to the at least one of the image display device or the user based on change in the state information within the determined period of time, and
generate the guidance information within the determined period of time based on the acquired environmental information.

11. The image display device according to claim 10 , wherein the one or more processors are further configured to stop at least a function in the image display device in a period of time other than the determined period of time.

12. The image display device according to claim 10 ,
wherein the one or more processors are further configured to acquire the state information related to the current position of the image display device and the current posture of the user and a temperature, and
wherein the one or more processors are further configured to generate the guidance information with respect to the current position or the current posture, based on the environmental information acquired by the one or more processors in a different position or in a different posture or at a different temperature within the determined period of time.

13. The image display device according to claim 1 , further comprising:
a memory that stores the environmental information acquired by the one or more processors in association with the state information at a time of acquisition,
wherein the one or more processors are further configured to generate guidance information based on the environmental information stored in the memory.

14. The image display device according to claim 1 ,
wherein the one or more processors are further configured to communicate with an external device that provides the environmental information,
wherein the one or more processors are further configured to acquire the environmental information from the external device, and
wherein the one or more processors are further configured to generate the guidance information based on the acquired environmental information.

15. The image display device according to claim 14 ,
wherein the external device includes at least one of another image display device or an information terminal other than the image display device that is mounted on another user, an information terminal that is installed
