US Patent 11983034 Wearable electronic device and compliant interface therefor

A compliant interface for a wearable electronic device includes a three-dimensional lattice structure that is coupleable to the wearable electronic device and compressible to conform to one or more of a facial feature or an upper cranial feature of a user wearing the wearable electronic device. The compliant interface may be one of a facial interface of a head-mounted display unit, a head interface of a head-mounted display unit, or a head interface of a headphones unit. The three-dimensional lattice structure may be formed of silicone that may form less than 35% of a volume of the three-dimensional lattice structure in an uncompressed state. Compliance of the facial interface may vary by locations at which the compliant interface engages the user. The compliance may vary according to one or more of geometric stiffness or maximum deflection of the three-dimensional lattice structure.
