A computer-implemented method for a gesture-based user interface for controlling a software program on an electronic device and a gesture-based user interface system are described wherein the method comprises the steps of receiving image data from a multi-aperture image sensor in said electronic device, said image sensor being adapted to simultaneously expose an image sensor to at least a first part of the electromagnetic (EM) spectrum using a first aperture and at least a second part of the EM spectrum using one or more second apertures; determining sharpness information in at least one area of said image data associated with at least part of an object, preferably at least part a human body part, imaged by said first aperture and said one or more second apertures onto the image plane of said image sensor; generating depth information, preferably one or more depth maps, on the basis of at least part of said sharpness information; and, recognizing on the basis of said depth information, at least part of a gesture associated with a movement of said object. |
