AI Technical Summary

Technical Problem

The lenses of existing head-mounted devices are difficult to adjust to best present content to each user, resulting in inconvenience.

Method used

An adjustable lens module is employed, comprising a transparent lens element, a lens forming structure, and an actuator. The curvature of the lens is adjusted by modifying the position and shape of the lens forming structure. Local modifications with different stiffness, width, thickness, or Young's modulus between adjacent extensions of the lens forming structure are used to achieve precise adjustment.

Benefits of technology

The lens module allows for flexible adjustment to suit the visual needs of different users, improving the adaptability and comfort of content presentation.

Abstract

A lens module can include a transparent lens element, a lens shaping structure coupled to the transparent lens element, and a plurality of actuators configured to adjust a position of the lens shaping structure to adjust the transparent lens element. The lens shaping structure can include a plurality of extensions, each coupled to a respective actuator. To ensure that the lens shaping structure has a desired curvature between the extensions, the lens shaping structure can have a portion in one or more sections between adjacent extensions that has a different characteristic size than additional portions of the lens shaping structure. The portion between the adjacent extensions can have an increased or decreased stiffness relative to the additional portions. The portion between the adjacent extensions can have a different width, thickness, or Young's modulus compared to the additional portions.
