Abstract: A method includes, at a controller, sensing a magnitude of a first force applied to the thumbstick in a substantially downward direction relative to a top portion of the housing while the thumbstick is in the stationary default position, and a magnitude of a second force applied to the thumbstick in the substantially downward direction relative to the top portion of the housing while the thumbstick is in a position other than the stationary default position. The method includes receiving the magnitude of the first and the second force, and determining whether the magnitude of the first force or the second force satisfies a predefined force value. The method further includes providing haptic feedback to the user in response to a determination that the magnitude of the first force or the second force satisfies the predefined force value.

Abstract: A head-mounted display (HMD) includes a hybrid fan, a printed circuit board (PCB) with one or more electronic components and a heat pipe to dissipate heat. The hybrid fan has a center axis extending from a rear side of the HMD to a front side of the HMD. The hybrid fan pulls air from a rear side of the HMD. The heat pipe has an end coupled to the PCB. The heat pipe partially surrounds a periphery of the hybrid fan and transfers heat away from at least the PCB. The HMD further includes a side cover and a front cover. The side cover encloses the hybrid fan, the PCB and the heat pipe. The front cover is attached to the side cover with a slit between an outer edge of the front cover and an outer edge of the side cover to discharge air from the hybrid fan.

Abstract: A device is configured to adjust interpupillary distance in a HMD. The device include a fixed plate, a button assembly, a spring, and a gear. The spring biases the button assembly towards the fixed plate to prevent movement of the button assembly. A button of the button assembly can be pressed beyond a threshold distance to disengage the button assembly and the fixed plate. Consequently, the button assembly can be moved relative to the fixed plate. The gear meshes with a gear rack of the button assembly and is associated with two display assemblies of the HMD. The movement of the button assembly drives the gear to rotate. The rotation of the gear causes the two display assemblies of the HMD to move in opposite directions. The movement of one of the display assemblies relative to the other display assembly adjusts interpupillary distance in the HMD.

Abstract: Systems and methods for implementing head mounted displays may include lens movement assemblies. A head mounted display system includes a display housing surrounding one or more display devices, a first lens and a second lens. An input device on the display housing includes a control member moveable between a first position and a second position. A lens movement assembly is operatively coupled to the input device and the first and second lenses and is configured to move the first lens relative to the second lens in response to movement of the control member between the first position and the second position.

Abstract: Technology is provided for a tracking constellation assembly for use in a virtual reality system. The tracking constellation assembly includes a translucent panel having an outward facing surface, and an inward facing surface and a mounting surface each opposite the outward facing surface. The translucent panel is substantially opaque to visible light and translucent to infrared light. The assembly includes a flexible circuit board including first and second opposed surfaces. A spacer interconnects the first surface of the flexible circuit board and the mounting surface of the translucent panel. Infrared light emitting diodes are connected to the flexible circuit board and positioned to direct light through the translucent panel.

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 metal frame in a head-mounted display (HMD) that is structured to absorb impact and protect components of the HMD. The metal frame has a wall that is spaced away from a protection shell securing a display panel in the HMD. When the HMD is dropped or subject to external force, the wall may deform but keep the protection shell intact. Moreover, the metal frame has protruding ridges and brackets that surround outward facing cameras on the HMD. If the HMD is dropped, the protruding ridges and brackets can provide protection to the cameras.
