Abstract: Systems and methods to custom-design gaskets for a virtual reality (VR) interface, wherein the VR interface includes a head mounted display (HMD) to be worn by users are disclosed. Exemplary implementations may obtain facial geometry information for a user's face; generate a representation of the surface of the user's face, based on the facial geometry information; align the representation with a representation of the HMD; generate a model of a three-dimensional gasket that fits between the representation of the surface of the user's face and the representation of the HMD; export and/or present the model of the three-dimensional gasket; and/or perform other steps. Such custom-designed gaskets may provide an improved fit with better optical alignment when compared to mass-produced gaskets.
