While Samsung has a slew of patents for smart glasses with a variety of features, a recently published patent application could be a breakthrough for those suffering from diabetic macular degeneration, which disrupts a user's central field of vision, including objects , face and text. The glasses appear to use its camera to view occluded images and move them to the periphery of the user's field of view so that they can see what is naturally occluded.
Smartglasses Displaying with Tangent Screen and Operation
The visual impairment may be classified into a visual continuity fault that generally refers to the intelligibility that a person can see, and a Visual Field Fault disorder that, when looking at one point on the front of the eye, represents the range of the appearance visible to that eye.
The macular degenerationin the field of viewmay be changed from the macular degeneration of the eye tissue to macular degeneration, which is the central portion of the retina, so that a portion to be reported may be darkened, distorted, or distorted, and thus, a central vision loss may occur due to a score that is a portion that is not visible in the center of the field of view.
When the central field of view fails due to macular degeneration, it is important to accurately identify the size and shape of the dark spot for treatment, and in this case, the size and shape of the dark spot may be identified by performing an inspection using a tangent screen.
In addition, when a center view defect occurs, the object may be recognized through a peripheral vision network trained through an eccentric viewing training fix. Below is Samsung's patent pending solution.
Samsung's patent FIG. 1 below is a view illustrating a head mounted display device in the form of smartglasses. This HMD #100 may include a display #110 and a gaze tracking sensor #120 that acquires information about the gaze direction #201-1 and 201-2 of the user #200 facing the display.
According to an operation method of the smartglasses the user may not display the center #112_1 of the content screen displayed on the display by changing the gaze direction #201_2 of the user in the middle of measuring the size and shape of the user's arm point #117 (FIG. 4). In this case, the glasses may change the position of the content screen #111_2 displayed on the display #110 to maintain a state in which the user watches the center #112_2 of the content screen and measure the size and shape of the dark spot #117 of the user. Therefore, the accuracy and reliability of the size and shape measurement operation of the arm point of the user may be increased.
Samsung patent FIG. 4 above illustrates the including a display #110, a gaze tracking sensor #120, a frame #160, and a nose support #170.
When a macular degeneration occurs in the macular #202 of the user, a dark spot may be located in the center of the visual field of the user to generate a central vision loss of the user #200. In an embodiment, in the process of displaying the tangent screen #111_1 and the at least one point #113_1 in the head mounted display device #100 to obtain the size and shape of the user's arm point #117_1, the user may give the center #112_1 of the tangent screen so that the user's viewpoint #210_1 and the center of the tangent screen should correspond to each other to obtain the exact size and shape of the dark spot #117_1.
The user may not recognize the center #112_1 of the tangent screen when the center #112_1 of the tangent screen is viewed by the central vision defect. Accordingly, in order to recognize the position of the center #112_1 of the tangent screen #111_1 using the peripheral vision camera #201_3, the user may watch a peripheral area other than the center of the tangent screen. Accordingly, the user's viewpoint #210_2 may not correspond to the center of the tangent screen displayed on the display #110.
In this case, the user may normally recognize the at least one point #113_1 to be viewed in a non-normal state when the user looks at the center #112_1 of the tangent screen using the surroundings #201_3. In addition, when the user has gazing at the center of the tangent screen, At least one point that is normally viewed using the periphery #201_3 may be included in the user's arm point #117_2 and appear non-stationary.
Accordingly, in the process of measuring the size and shape of the user's dark points #117_1 and #117_2 by using the tangent screen #111_1 and the at least one point #113_1, when the user's gaze directions #201_1 and #201_2 are changed, the dark points #117_1, #117_2) may not be obtained.
Samsung's patent FIG. 8A above is a diagram for describing changing a position of at leastone point into a random pattern;FIG. 8B is a diagram for describing changing a position of at leastone point to a preset position pattern.
