Our first patent report of the day was titled "Apple Patent reveals Future HMD with Physiological Sensors built-in to Monitor Facial Comfort, Heart Rate, Brain Activity and more." In a second patent application made public today by the U.S. Patent Office Apple focuses more on the mechanics of the fit and stability of this future headset sitting on a user's face.
Apple notes that this patent covers a head-mounted display system that includes a display unit and a facial interface. The display unit includes a display for displaying graphical content to a user. The facial interface is coupled to the display unit and configured to engage a face of the user to support the display.
The facial interface includes an upper portion that engages a forehead of the user and side portions that engage temple regions of the user. The facial interface converts forward force applied to the upper portion by the forehead into inward force applied by side portions to the temple regions.
The facial interface may include a force distributor having an upper segment that forms the upper portion and two side segments that form the side portions, and forward movement of the upper segment causes inward movement of the side segments.
The display unit and the facial interface may be cooperatively configured to block environmental light from eyes of the user. The facial interface may include a lateral stabilizer that selectively transfers force between one of the side portions and the display unit.
The lateral stabilizers may be selectively operated upon sensing a movement condition of the display unit. The display unit and the facial interface are cooperatively configured block environmental light from eyes of the user.
Apple's patent FIG. 1A below is a side view of a head-mounted display worn on a head of a user; FIG. 1B is a partial top view of the head-mounted display of FIG. 1A.
Apple's patent FIG. 4A above is a top view of the head-mounted display of FIG. 1A illustrating an embodiment of a facial interface thereof in a first state (solid lines) and a second state (dash-dash lines); FIG. 4B is a top view of the head-mounted display of FIG. 4A with the head of the user engaging the facial interface in the second state.
Further, the facial interface #430 may include an outer cover #432. The outer cover engages the face of the user and may also cover underlying mechanisms (e.g., force distributors) that transfer force and movement.
The outer cover may be opaque and engage the face of the user in a substantially continuous manner to block environmental light from entering therebetween
Apple's patent FIGS. 5A-5C below illustrates, a facial interface #530 includes an internal force distributor #534, which functions to transfer force and cause movement for the facial interface #430. Further, the facial interface may additionally include one or more lateral stabilizers #540 that further stabilizes the head-mounted display on the user's head H of the user.
Apple's patent application 20200233453 that was published today by the U.S. Patent Office was filed back in Q1 2020 with some work being done in 2019. This is a detailed patent and to dig deeper you check out Apple's patent application here.
Considering that this is a patent application, the timing of such a product to market is unknown at this time.
