Abstract
Improved augmented reality smartglasses ensure alignment of displays in a head-mounted wearable device such as AR smartglasses by specifying a relationship between material properties of the frame at the shoulder and nose bridge. For example, such a material relationship may be a rigidity and/or stiffness characteristic. In some implementations, the specified relationship is that a difference between the first bending stiffness and the second bending stiffness is less than a tolerance (e.g., 5%, 1%, or less than 1%).
Claims10
A head-mounted wearable device, including:
- a left display and a right display;
- a frame worn by a user, including:
- a left rim portion in which the left display is mounted;
- a right rim portion in which the right display is mounted;
- a nose bridge joining the left rim portion and the right rim portion, the nose bridge being formed of a first material having a first bending stiffness;
- a left arm portion forming a left shoulder with the left rim portion;
- and
- a right arm portion forming a right shoulder with the right rim portion, each of the left shoulder and right shoulder being formed of a second material having a second bending stiffness, the first bending stiffness and the second bending stiffness satisfying a specified relationship.

A method, comprising:
- in a frame of a head-mounted wearable device that includes a left display and a right display:
- mounting the left display on a left rim portion of the frame;
- mounting the right display on a right rim portion of the frame;
- joining the left rim portion and the right rim portion with a nose bridge, the nose bridge being formed of a first material having a first bending stiffness;
- forming a left shoulder with the left rim portion and a left arm portion of the frame;
- and
- forming a right shoulder with the right rim portion and a right arm portion of the frame, each of the left shoulder and right shoulder being formed of a second material having a second bending stiffness, the first bending stiffness and the second bending stiffness satisfying a specified relationship.
