Abstract
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.
Claims19
A method for enabling a user to select a particular option from a set of selectable options, the method comprising the steps of:
- displaying the set of selectable options at respective option positions;
- while allowing the user to physically point at the particular option, taking a single image of the user, wherein the single image does not include an image of the selectable options;
- ascertaining from the single image whether the user points at the particular option;
- if such is the case, concluding that the user has selected the particular option;
- and
- based on the single image, determining a feature position of a body feature of the user in 3 dimensional space;
- the step of ascertaining from the single image whether the user has pointed at the particular option being executed on the basis of the feature position of the body feature and the option position of the particular option.
A system for enabling a user to select a particular option from a set of selectable options, the sysytem comprising:
- display means for displaying the set of selectable options at respective option positions;
- a single image taking means for taking a single image of the user, wherein the single image does not include an image of the selectable options;
- ascertaining means for ascertaining from the single image whether the user points at the particular option;
- concluding means for concluding that the user has selected the particular option, in the case that the ascertaining means have ascertained that the user points at the particular option;
- and
- feature determining means for based on the single image determining a feature position of a body feature of the user in 3 dimensional space;
- the ascertaining means being arranged to ascertain whether the user points at the particular option on the basis of the feature position of the body feature and the option position of the particular option.
A program stored on a computer readable medium for enabling a user to select a particular option from a set of selectable options, the program comprising:
- an execution portion for displaying the set of selectable options at respective option positions on a display;
- an execution portion for initiating a single imaging of the user pointing at the particular option, wherein the single imaging does not include an imaging of the selectable options;
- an execution portion for determining from the single image whether the user points at the particular option on the basis of a feature position of a body feature of the user in a three-dimensional space and the option position of the particular option.
