Future Apple AR devices, such as “Apple Glass,” may include holograms to make moving through virtual environments feel more natural.
Apple has already very many patents and patent applications concerning displaying information on “Apple Glass,” or similar devices. There’s the possibility, for instance, that when you hold up two items in an Apple Store, the glasses could display a bullet list of the differences and similarities.
“Scene camera,” by UK-based inventors Richard J. Topliss and Michael David Simmonds, wants to supplement images on “Apple Glass” with holographic ones. The aim is to make wearers feel, “as if they were physically in that environment.”
“For example, virtual reality systems may display stereoscopic scenes to users in order to create an illusion of depth,” says the patent, “and a computer may adjust the scene content in real-time to provide the illusion of the user moving within the scene.”
“When the user views images through a virtual reality system, the user may thus feel as if they are moving within the scenes from a first-person point of view,” it continues. “Mixed reality (MR) covers a spectrum from augmented reality (AR) systems that combine computer generated information (referred to as virtual content) with views of the real world to augment, or add virtual content to, a user’s view of their real environment…”
The patent doesn’t specify — or need to specify — how other “Apple Glass” systems will present virtual objects, so it’s not clear how a holographic one would fit in with previous designs. This particular proposal, though, aims to have projectors mounted to the side of the glasses to create what Apple refers to as a “scene camera.”
“To achieve a more accurate representation of the perspective of the user, the scene camera is located on the side of the MR headset and facing the inside surface of the lens,” says Apple. “The lens includes a holographic medium recorded with one or more transmission holograms that diffract a portion of the light from the scene that is directed to the user’s eye to the scene camera. Thus, the scene camera captures images of the environment from substantially the same perspective as the user’s eye.”
