Abstract
A wearable device, which comprises: a ring-shaped case having an opening part formed in the middle thereof; a projector mounted at one side of the case and outputting an image; a lens part adjusting the direction and the size of the image, which is projected from the projector, so as to project the image; and a control unit for adjusting the projector and the lens part according to an image signal, can deliver visual information to a user wearing the wearable device even without a separate display unit by outputting the image onto the hand of the user.
Claims16
A wearable device comprising:
- a case having a ring shape, the ring shape of the case defining an opening at a center of the case, the opening being configured to receive a wrist of a user;
- a projector located in the case, the projector being configured to output an image toward a hand of the user when the wrist of the user is located in the opening of the case;
- a sensor located in the case, the sensor being configured to sense a bent angle of the user's wrist;
- a lens module configured to:
- receive the image from the projector at a side of the lens module;
- adjust a direction of the image;
- adjust a size of the image;
- and
- project the image at a front of the lens module;
- and
- a controller configured to control the projector and the lens module in accordance with the bent angle of the user's wrist,
- wherein the lens module includes:
- a first reflective plate configured to receive the image incident at the side of the lens module and to reflect the image in a radial direction of the ring shape of the case,
- a second reflective plate configured to receive the image reflected by the first reflective plate and to reflect the image in an axial direction of the ring shape of the case,
- a first lens configured to reduce a size of the image incident at the size of the lens module, and to deliver the image to the first reflective plate, and
- a second lens located between the first reflective plate and the second reflective plate, the second lens being configured to magnify the image reflected by the first reflective plate, and to deliver the image to the second reflective plate.
