Abstract: Accordingly, the embodiments of the disclosure provide a method for determining refractive power of an eye of a wearer. The method includes causing to display, by a first electronic device (100), a virtual image of at least one optotype on a display (202) of a second electronic device (200). Further, the method includes varying, by the first electronic device (100), a focus of the optotypes to provide changes in an optical prescription. Further, the method includes conducting, by the first electronic device (100), an eye exam of the wearer based on the varied focus of the optotypes. Further, the method includes determining, by the first electronic device (100), the refractive power of the eye of the wearer.

Abstract: Embodiments herein disclose a method and electronic device for determining skin information by an electronic device using hyper spectral reconstruction. The method further includes capturing a Red, Green, and Blue (RGB) image of a skin. The method further includes converting the RGB image into a hyper spectral image. The method further includes determining at least one wavelength band by applying a wavelength reflectance model on the hyper spectral image and determining information of the skin by applying a neural network model on the wavelength bands.

Abstract: A method for generating a three-dimensional (3D) biometric model of a user's body part is provided. The method includes detecting, by at least one imaging sensor of the electronic device, the body part, capturing by the at least two imaging sensors a first image of a first portion of the body part and a second image of a second portion of the body part, generating the 3D biometric model of the body part using the first image and the second image of the body part, and storing the 3D biometric model of the body part.

Abstract: A method and an electronic device for measuring blood pressure are provided. The method includes illuminating, by a PPG sensor included in the electronic device, skin of a user and measuring a PPG signal based on an illumination absorption by the skin. Further, the method also includes extracting, by the electronic device, a plurality of parameters from the PPG signal, wherein the parameters may comprise PPG features, Heart Rate Variability (HRV) features, Acceleration Plethysmograph (APG) features, and non-linear features. The method also includes estimating, by the electronic device, the BP based on the extracted plurality of parameters.
