Abstract: A haptic skull cap provides different types of haptic feedback to a user, which can be advantageous for providing a more immersive virtual reality experience. The haptic skull cap includes a fabric cap worn by a user. Physically attached to the fabric cap is a linear actuator that provides a focal impact to a user's forehead. Additionally, vibrational motors are physically attached to the fabric cap, where each vibration motor provides vibrational feedback to a different location of the user's head. The haptic skull cap can be worn by a user in conjunction with a head mounted display. Therefore, each type of haptic feedback provided by the haptic skull cap can be synchronized with the visual data stream provided by the head mounted display which further enhances the overall virtual reality experience for a user.

Abstract: Embodiments relate to a rotatable hinge for a head strap connector of a head-mounted display (HMD) that is detachable. The rotatable hinge has frictional elements that allow resistive rotation of the head strap connector relative to the HMD. The rotatable hinge has an end piece connected to the head strap connector that may be interlocked with the HMD by inserting the end piece into a cavity of the HMD and rotating the end piece in the cavity. The cavity has pins that pass through the end piece and interlock with walls along the outer edge of the end piece. Once interlocked with the HMD, the pins interlocked with the end piece allow the end piece to pivot relative to the HMD allowing the head strap connector to adjust to the size of a user's head.
