A stereoscopic pictures generating method comprising: - a providing step comprising: ∘ a first providing operation during which at least one first user related parameter is provided, and ∘ a second providing operation during which at least one second user related parameter is provided, - a determining step comprising: ∘ a first determining operation during which a first picture parameter is determined based on the first user related parameter, the first picture parameter comprising a first distance to be set between two cameras embedded in a screen facing the second user, and ∘ a second determining operation during which a second picture parameter is determined based on the second user related parameter, the second picture parameter comprising a second distance to be set between two cameras embedded in a screen facing the first user, and - a generating step comprising: ∘ a first generating operation during which right and left stereoscopic pictures are generated based on the first picture parameter, the right and left stereoscopic pictures being to be displayed on the screen facing the first user, and ∘ a second generating operation during which right and left stereoscopic pictures are generated based on the second picture parameter, the right and left stereoscopic pictures being to be displayed on the screen facing the second user, wherein the first and second user related parameters comprise the interpupillary distance of the corresponding user in close vision, in intermediary vision, or in far vision, and the first and second user related parameters comprise the distance between the corresponding user and the screen. - a providing step comprising: ∘ a first providing operation during which at least one first user related parameter is provided, and ∘ a second providing operation during which at least one second user related parameter is provided, ∘ a first providing operation during which at least one first user related parameter is provided, and ∘ a second providing operation during which at least one second user related parameter is provided, - a determining step comprising: ∘ a first determining operation during which a first picture parameter is determined based on the first user related parameter, the first picture parameter comprising a first distance to be set between two cameras embedded in a screen facing the second user, and ∘ a second determining operation during which a second picture parameter is determined based on the second user related parameter, the second picture parameter comprising a second distance to be set between two cameras embedded in a screen facing the first user, and ∘ a first determining operation during which a first picture parameter is determined based on the first user related parameter, the first picture parameter comprising a first distance to be set between two cameras embedded in a screen facing the second user, and ∘ a second determining operation during which a second picture parameter is determined based on the second user related parameter, the second picture parameter comprising a second distance to be set between two cameras embedded in a screen facing the first user, and - a generating step comprising: ∘ a first generating operation during which right and left stereoscopic pictures are generated based on the first picture parameter, the right and left stereoscopic pictures being to be displayed on the screen facing the first user, and ∘ a second generating operation during which right and left stereoscopic pictures are generated based on the second picture parameter, the right and left stereoscopic pictures being to be displayed on the screen facing the second user, ∘ a first generating operation during which right and left stereoscopic pictures are generated based on the first picture parameter, the right and left stereoscopic pictures being to be displayed on the screen facing the first user, and ∘ a second generating operation during which right and left stereoscopic pictures are generated based on the second picture parameter, the right and left stereoscopic pictures being to be displayed on the screen facing the second user,
