The system displays on a screen a set of options that are selectable by a user. The user standing in front of the screen points at a desired option and a camera of the system takes an image of the user while pointing. The system calculates from the pose of the user in the image whether the user is pointing to any of the displayed options. If such is the case, that particular option is selected and an action corresponding with that option is executed. This known housing has radially resilient clamping limbs arranged in a circle and having radially outward clamping surfaces for engagement in a central opening of a disc-shaped information carrier.

[ What is claimed is:] [1.] A method for enabling a user to select a particular option from a set of selectable options, the method comprising:displaying the set of selectable options at respective option positions;taking an image of the user while allowing the user to physically point at the particular option;determining a foot position of a foot of the user, a projection of an arm of the user on the plane of the image and a long axis of the body of the user on the plane of the image based on the image;ascertaining from the image whether the user points at the particular option;if such is the case, concluding that the user has selected the particular option; andbased on the image, determining a feature position of a body feature of the user in 3 dimensional space bydetermining the distance between the option position of the particular option and the foot position, determining a first angle between the projection of the arm of the user and the projection of the long axis of the body of the user, and determining a second angle between the arm of the user and the plane of the image on the basis of an estimated arm length of the arm of the user and a determined length of the projection of the arm, wherein the estimated arm length is obtained from biometrics data on the basis of the height of the user, and wherein ascertaining from the image whether the user has pointed at the particular option is executed on the basis of the feature position of the body feature and the option position of the particular option.
