Definitions

  • the wearable device of the first aspect of the present disclosure includes a front unit having at least an optical engine block that projects image display light to show an image to a user, and a light guide plate that guides the image display light to reach the user's eyeballs, and is positioned in front of both ears of the user when worn by the user, and a rear unit having at least a board block in which a board is incorporated, and a battery block in which a battery is incorporated, and is positioned behind both ears of the user when worn by the user, the front unit being independently configured with a right front unit that is positioned in front of the user's right ear and a left front unit that is positioned in front of the user's left ear, and the right front unit and the left front unit are connected by the rear unit.
  • the front unit has at least an optical engine block that projects image display light to show an image to the user, and a light guide plate that guides the image display light to reach the user's eyeballs, and is positioned in front of the user's ears when worn by the user
  • the rear unit has at least a board block in which a board is incorporated, and a battery block in which a battery is incorporated, and is positioned behind the user's ears when worn by the user.
  • the front unit is configured independently of a right front unit that is positioned in front of the user's right ear, and a left front unit that is positioned in front of the user's left ear, and the right front unit and left front unit are connected by the rear unit.
  • the wearable device of the second aspect of the present disclosure comprises a front unit having at least an optical engine block that projects image display light to show an image to a user, and a light guide plate that guides the image display light to reach the user's eyeballs, and is positioned in front of both ears of the user when worn by the user, and a rear unit having at least a board block incorporating a board electrically connected to the optical engine block, and a battery block incorporating a battery that supplies power to the optical engine block, and is positioned behind both ears of the user when worn by the user.
  • the front unit has at least an optical engine block that projects image display light to show an image to a user, and a light guide plate that guides the image display light to reach the user's eyeball, and is positioned in front of both ears of the user when worn by the user
  • the rear unit has at least a battery block that incorporates a battery that supplies power to the optical engine block, and is positioned behind both ears of the user when worn by the user.
  • the left side pad portion 41L is configured with a cushioned pad.
  • the left side pad portion 41L is provided so as to be convex toward the inside of the wearable device 11, and the pad is provided so as to abut near the front of the left ear (see FIG. 6 described below) when the user wears the wearable device 11.
  • a slit is provided on the rear side of the left side pad portion 41L, and the sound output from the speaker built into the switch block 35 is configured to pass through this slit toward the user's left ear.
  • the neckband 53 is configured with wiring that electrically connects the main board block 51 and the right front unit 21R to the battery block 52 and the left front unit 21L, and connects each block arranged on the right side of the wearable device 11 to each block arranged on the left side of the wearable device 11.
  • the neckband 53 is also configured, for example, from an elastic body that has a force that moves toward the inside of the wearable device 11, and can generate a wearing pressure when the user wears the wearable device 11.
  • FIG. 5 shows a right side view of the wearable device 11 when worn by a user
  • FIG. 6 shows a left side view of the wearable device when worn by a user.
  • the wearable device 11 If the angle ⁇ between the front unit 21 and the rear unit 22 of the wearable device 11 is too small, the center of gravity will be high and the device will become unstable. On the other hand, if the angle ⁇ between the front unit 21 and the rear unit 22 is too large, the rear unit 22 will hit the user's neck when the user looks up. Therefore, it is preferable to configure the wearable device 11 so that this angle ⁇ is in the range of 10° to 25°, and more preferably in the range of 15° to 20°.
  • the wearable device 11 can adjust the display position of the image by the image display light without departing from the eyebox by rotating the light guide plate 31 and the optical engine block 32 based on the center of the user's right eyeball Eye.
  • the wearable device 11 is configured so that the distance from the user's right eyeball Eye to the light guide plate 31 remains constant even when the light guide plate 31 and the optical engine block 32 are rotated to adjust the display position of the image by the image display light. In this way, the wearable device 11 can adjust the display position left and right while minimizing changes in the display distance (eye relief) of the image by the image display light.
  • the display position can be adjusted up and down while minimizing changes in the image display distance caused by the image display light.
  • the wearable device 11 can also be made slimmer by configuring the movable mechanism so that the axis for rotating the light guide plate 31 and the optical engine block 32 is positioned rearward of the center of the optical engine block 32 (e.g., upward in A of FIG. 8, or to the left in B of FIG. 8).
  • the wearable device 11A is configured differently from the wearable device 11 in FIG. 1 in that a neckband 53R is connected to the right ear hook 23R, a neckband 53L is connected to the left ear hook 23L, and a circuit board battery block 61 is provided between the neckband 53R and the neckband 53L.
  • the wearable device 11A configured in this manner can also provide improved convenience, similar to the wearable device 11 in FIG. 1. Furthermore, the wearable device 11A can provide a lower center of gravity due to the board battery block 61, thereby improving stability when worn by the user.
  • the wearable device 11 can be configured so that the light guide plate 31 and the optical engine block 32 are disposed on the left side of the user's head so that image display light is projected onto the user's left eye.
  • the wearable device 11 may also be configured so that the light guide plate 31 and the optical engine block 32 are provided on both sides so that image display light is projected onto both of the user's eyes.

Abstract

La présente invention concerne un dispositif habitronique qui permet d'améliorer encore la convivialité. Une unité frontale du dispositif habitronique comporte au moins un bloc de moteur optique et une plaque de guidage de la lumière, et est disposée en avant des deux oreilles de l'utilisateur lorsqu'il est porté par ce dernier. L'unité arrière comporte au moins un bloc de substrat principal et un bloc-batterie, et est placée à l'arrière des deux oreilles de l'utilisateur lorsque celui-ci la porte. L'unité frontale est constituée d'une unité frontale droite disposée en avant de l'oreille droite de l'utilisateur et d'une unité frontale gauche disposée en avant de l'oreille gauche de l'utilisateur, l'unité frontale droite et l'unité frontale gauche étant indépendantes l'une de l'autre. L'unité avant droite et l'unité avant gauche sont reliées à l'aide de l'unité arrière. La présente technologie peut être appliquée, par exemple, à un dispositif habitronique utilisé pour la réalité augmentée (AR).
