Abstract
A transmissive display device includes an image display unit configured to transmit an outside scenery and display an image viewable with the outside scenery, an interference risk region calculation unit configured to calculate an interference risk region where there is a risk of interference between a user of the transmissive display device and a mobile body, a risk level determination unit configured to determine a risk level of the interference, based on a relative positional relationship between the user and the mobile body, and a display control unit configured to display, on the image display unit, an image indicating the interference risk region in a display mode according to the determined risk level.
Claims13
A head-mounted transmissive display device that is worn by a user, the head-mounted transmissive display device comprising:
- an image display configured to transmit an outside scenery and display an image viewable with the outside scenery in the image display;
- and
- a processor programmed to:
- display, in the image display, an interference risk region in the image in accordance with a display mode, the interference risk region indicating a risk of interference between the user of the head-mounted transmissive display device and a mobile body,
- determining a position of the mobile body in a vicinity of the user,
- determine the risk level of interference between the user of the head-mounted transmissive display device and the mobile body based on the determined position of the mobile body,
- change the display mode of the interference risk region based on the determined risk level, and
- display the changed display mode in the image display, wherein:
- changing the display mode of the interference risk region includes at least one of:
- (a) changing a shape of the interference risk region in the image, (b) changing a size of the interference risk region in the image, (c) changing a transparent color of the interference risk region in the image, and/or (d) initiating or changing an on/off blinking of the interference risk region in the image.
A display control method for a head-mounted transmissive display device that is worn by a user, the head-mounted transmissive display device including an image display configured to transmit an outside scenery and display an image viewable with the outside scenery, the display control method comprising:
- displaying, in the image display, an interference risk region in the image in accordance with a display mode, the interference risk region indicating a risk of interference between the user of the head-mounted transmissive display device and a mobile body,
- determining a position of the mobile body in a vicinity of the user,
- determining the risk level of interference between the user of the head-mounted transmissive display device and the mobile body based on the determined position of the mobile body,
- changing the display mode of the interference risk region based on the determined risk level, and
- displaying the changed display mode in the image display, wherein:
- changing the display mode of the interference risk region includes at least one of:
- (a) changing a shape of the interference risk region in the image, (b) changing a size of the interference risk region in the image, (c) changing a transparent color of the interference risk region in the image, and/or (d) initiating or changing an on/off blinking of the interference risk region in the image.
A non-transitory computer readable medium storing a computer program for performing display control in a head-mounted transmissive display device that is worn by a user, the head-mounted transmissive display device including an image display configured to transmit an outside scenery and display an image viewable with the outside scenery, the computer program causing a computer to perform steps comprising:
- displaying, in the image display, an interference risk region in the image in accordance with a display mode, the interference risk region indicating a risk of interference between the user of the head-mounted transmissive display device and a mobile body,
- determining a position of the mobile body in a vicinity of the user,
- determining the risk level of interference between the user of the head-mounted transmissive display device and the mobile body based on the determined position of the mobile body,
- changing the display mode of the interference risk region based on the determined risk level, and
- displaying the changed display mode in the image display, wherein:
- changing the display mode of the interference risk region includes at least one of:
- (a) changing a shape of the interference risk region in the image, (b) changing a size of the interference risk region in the image, (c) changing a transparent color of the interference risk region in the image, and/or (d) initiating or changing an on/off blinking of the interference risk region in the image.
