First Claim
Patent Images
1. A head mounted display comprising:
- a display part configured to project an image light corresponding to display information on an eye of a user thus allowing the user to visually recognize the image corresponding to the image light while allowing an external light to pass therethrough;
a memory part configured to store first information, a standard time and second information, the standard time and the second information being associated with the first information respectively;
an imaging part configured to image at least a portion of a field-of-view range of the user; and
a processor accessing a memory to execute instructions that effect;
an image analyzing unit configured to analyze an image imaged by the imaging part;
a hand detection determination unit configured to determine whether or not a hand of the user is included in a field angle of the imaging part based on a result of an analysis carried out by the image analyzing unit;
a display starting unit configured to allow the display part to start playing of the first information stored in the memory part when the hand detection determination unit determines that the hand of the user is included in the field angle;
a display switching unit configured to switch the playing of the first information to playing of the second information associated with the first information when the hand detection determination unit determines that the hand of the user is included in the field angle and the standard time associated with the first information elapses from a point of time that the playing of the first information is started by the display part; and
a display finishing unit configured to finish the playing of the first information or the second information which are played when the first information or the second information is played by the display part and the hand detection determination unit determines that the hand of the user is not included in the field angle.

Abstract
In a head mounted display, when it is determined that a hand of a user is in a field angle, the head mounted display starts the playing of main manual information. When a standard time elapses after starting the playing of the main manual information without the determination that the hand of the user is not included in the field angle, the playing of the main manual information is switched to the playing of sub manual information. When it is determined that the hand of the user is not included in the field angle in a state where the playing of the main manual or the sub manual is underway, the playing of the main manual information or the sub manual operation underway is finished.

9. A method of displaying information by a head mounted display, the method comprising the steps of:
-
an imaging step imaging at least a portion of a field-of-view range of a user; an analyzing step analyzing an image imaged in the imaging step; an determination step determining whether or not a hand of a user is in the image based on a result of analysis in the image analyzing step; a display starting step starting the playing of first information on a display part when it is determined that the hand of the user is included in the image in the determination step, the display part allows a user to visually recognize an image corresponding to an image light by projecting the image light corresponding to the display information to an eye of a user while allowing the transmission of an external light therethrough, the first information is stored in a memory part which stores the first information, a standard time and a second information, the standard time and the second information being associated with the first information; a switching step switching the playing of the first information to the playing of the second information associated with the first information undergoing the playing when it is not determined that the hand of the user is not in the image in the determination step and the standard time associated with the first information undergoing the playing elapses after starting the playing of the first information in the display starting step; and a finishing step finishing the playing of the played first and second information undergoing the playing when it is determined that the hand of the user is not in the image in the determination step in a case where the first information or the second information is played in the display starting step or the switching step.
