In the run-up to the launch of Magic Leap One, Magic Leap was skeptical of what the actual field of view (FoV) is for its first commercial product.
Now a developer noticed that the client-side source code of FoV documentation (published last month as a placeholder with just the text "coming soon on launch day!") Already contained the final text of the document in a commented out block of markdown and Uncovered Mystery
The hidden text lists a horizontal FoV value of 40 degrees, a vertical value of 30 degrees, and a diagonal of 50 degrees, resulting in an aspect ratio of 4: 3. Compared to the HoloLens and its aspect ratio of 16: 9, the FoV of the Magic Leap One is horizontally only one third larger, but almost twice as high as the vertical value or about 45% larger.
Magic Leap also provides some examples of the context. At 40 inches, the FoV is enough to show a large domestic cat. At 144-inches, Magic Leap One can show a trio of six foot tall people.
It seems Magic Leap will also try to coin the term "Viewing Bubble Gum" instead of FoV to describe the space in which 3D objects
The larger digital FoV combined with Magic Leap On's circular eyebox Design, which obscures the user's peripheral vision, thereby reducing the natural FoV, Magic Leap should be achieving a less disturbing effect.
The code also introduces the Rain-Sample experience, in which Magic Leap instructs developers how to use a vignette technique so that content at the edges of the FoV fades in and fades away abruptly. Suppose that at the end of a scene in a movie, black becomes black rather than black.
Because the Magic Leap One displays the color black as invisible, developers can use it to apply a mask to the content of custom vignettes. To further support this technique, Magic Leap has integrated system-level vignettes that developers can use in their apps.
The specified FoV ends up being larger than that of Rolling Stone Author Brian Crecente described in his hands-on work with the device. However, from a hardware and software perspective, Magic Leap's approach is consistent with Crescente's statement that Magic Leap "is working to make it less obvious."
So the Magic Leap One will outperform the first-generation HoloLens in terms of FoV, and it can be a long way from other headsets, like Meta 2. If Microsoft applies its latest research and patents in its next iteration of HoloLens, Magic Leap will have some catching up to do.
We have embedded the following hidden text:
Field of View is widely used in XR to measure the visible area a person can see through a device like Magic Leap One. Although helpful in providing a baseline measure, the field of view may be misleading because it is a 2D concept and does not fully describe the three-dimensional attributes of the directly visible space directly through our device. A 2D field of view is a relative measure and depends on the depth and scale of the content being viewed.
Instead, the term "viewing frustum" (or "view frustum") better describes the three-dimensional space in which light field objects are viewed. With a focus on design guidelines and best practices, our volumes can range from hand-sized characters to larger objects such as 90 "TV screens or even spaceships – Spatial Computing is about working in volumes and spaces, not just a 2D field of view For the context, here is a list of the real world elements and the distance from where they would be completely contained in the device's view frustum:
- At 40 inches away, a large domestic cat, laying down (29 "long 21 "high) would be completely within the visual truncated cone.
- At 75 inches distance, a standing big dog like a Labrador or Retriever (54" long, 40 "tall) would be completely in the sight truncated cone 90-inch widescreen TV (80 "long, 58" high) completely in the stare.
- At 144 inches away, you can fully raise a family of three 6 foot tall people stand side by side inside the sight truncated cone At 144 inches, the field of view is 104 inches long and 77 inches high. 19659023] All said, as a developer you need to know the operating values of the device. Magic Leap One has a horizontal field of view of 40 degrees, a vertical field of view of 30 degrees and a diagonal field of view of 50 degrees. The following documents and examples will tell you more about how to work with the device to get more content and experiences that will feel good to your users.
This is just the last piece of information that suggests that the Magic Leap One will be available soon and in the hands of developers who have been waiting for years for "Spatial Computing." Try it.
