In one embodiment, the patent describes an augmented reality head-mounted display system comprising an eyepiece having a transparent emissive display. The goggles and the transparent emitting display are disposed in the optical path of a user's eye so as to transmit light into the user's eye to form an image. Due to the transparent nature of the display, the user can see the external environment through the transparent emitting display. The transmissive emissive display comprises a plurality of emitters, said plurality of emitters configured to emit light into the user's eye.
57.《Magic Leap Patent | Systems and methods for augmented reality》
In one embodiment, the patent describes a method for reducing errors in noisy data received from a high frequency sensor by collecting a first set of dynamic inputs from the high frequency sensor, collecting a correction input point from the low frequency sensor, fusing the received inputs with data received from the low frequency sensor, and damping the correction input point by a full translation to the correction input point or a damping method towards the correction input point, based on the correction input point to adjust the propagation path of a second set of dynamic inputs from the high frequency sensor.
58.《Magic Leap Patent | Reverberation fingerprint estimation》
In one embodiment, the patent describes systems and methods for estimating acoustic characteristics of an environment. In the example method, a microphone of a wearable head device receives a first audio signal. An envelope of the first audio signal is determined and a first reverberation time is estimated based on the envelope of the first audio signal. A difference between the first reverberation time and the second reverberation time is determined. Determining a change in the environment based on the difference between the first reverberation time and the second reverberation time. A speaker of the wearable head device presents a second audio signal, wherein the second audio signal is based on the second reverberation time.
In one embodiment, the patent describes non-equally spaced light emitting devices that can be used in displays in augmented reality, virtual reality, and mixed reality environments. Specifically, the patent primarily relates to non-equally spaced small light emitting devices, such as Micro-LEDs.The patent also describes systems and methods for emitting a plurality of light through a plurality of panels, wherein the spacing of one panel is different from the spacing of the other panels. Each panel may include a corresponding array of light emitters. The plurality of lights may be combined by a combiner.
60.《HTC Patent | Virtual reality device (HTC Patent: Virtual reality device)》
In one embodiment, the virtual reality device described in the patent includes a main body portion, a plurality of first type antennas, and a plurality of second type antennas. The main body portion has a first side eyeglass frame, a second side eyeglass frame, and a connection portion. The connecting portion is connected to the first side eyeglass frame and the second side eyeglass frame. The second type antennas and the corresponding first type antennas are provided on the first side of the first side eyeglass frame, on the second side of the second side eyeglass frame, and on the connecting portion, respectively. The first side of the first side spectacle frame is opposite to the second side of the second side spectacle frame.
61.《HTC Patent | Speaker module and wearable device (HTC Patent: Speaker module and wearable device)》
In one embodiment, a speaker module is configured to a wearable device. The speaker module includes a housing and a driver unit. The driver unit is used to generate sound. A sum of sounds of sounds output from a front opening, a first rear opening and a second rear opening of the housing has a directivity. A connection vector defined by the openings and an inverse vector of the connection normal vector are added to form a combination vector. A unit vector of the combination vector and a unit vector of the front normal vector facing the outside of the front opening are added to form a sum vector. The direction of the sum vector is the direction of the sound sum.
