MUMBAI, India, Nov. 7 -- Intellectual Property India has published a patent application (202514026628 A) filed by Distance Technologies Oy, Helsinki, on March 23, for 'light field display based on relative location of viewer.'
Inventor(s) include Urho Konttori; Joonas Itaranta; and Mikko Strandborg.
The application for the patent was published on Nov. 7, under issue no. 45/2025.
According to the abstract released by the Intellectual Property India: "Tracking means (104) are utilised to determine a relative location of a first eye (124a, 202a, 312a, 416a, 422a, 504, 806a) and of a second eye (124b, 202b, 312b, 416b, 422b, 504, 806b) of user(s) (126) with respect to an optical combiner (108). An input (502) for a light field display unit (106, 302, 400, 804) is generated, based on the relative location of the first eye and of the second eye. The input is employed at the light field display unit to produce a synthetic light field (130), wherein the optical combiner is employed to reflect a first part and a second part of the synthetic light field towards the first eye and the second eye, respectively, whilst optically combining the first part and the second part of the synthetic light field with a real-world light field (112) of a real-world environment (102)."
