A computer-implemented method for installing a first physical element on or in a second physical element, the method comprising: receiving (S201-S205), by an augmented reality system comprising smart eyewear, a projector and a sensor for recognizing physical elements, an indication of at least one of a first physical element and a second physical element; loading, by the augmented reality system and using the indication, a model of the second physical element; recognizing, by the augmented reality system, the second physical element based on the model; projecting, by the augmented reality system, an image corresponding to the first physical element on or in the second physical element; and validating, by the augmented reality system, whether the first physical element has been correctly installed on the second physical element, wherein validating whether the first physical element has been installed correctly comprises: receiving, by the augmented reality system, an indication from a user via a voice command that the first physical element has been installed; and recognizing, by the augmented reality system, whether the first physical element is in a predetermined installation location on the second physical element, wherein said recognizing, by the augmented reality system, whether the first physical element is in a predetermined installation location on the second physical element comprises: capturing, using the sensor, an image of the first physical element and at least part of the second physical element; and determining, by the augmented reality system and based on the captured image, whether the first physical element has been correctly installed.. receiving (S201-S205), by an augmented reality system comprising smart eyewear, a projector and a sensor for recognizing physical elements, an indication of at least one of a first physical element and a second physical element; loading, by the augmented reality system and using the indication, a model of the second physical element; recognizing, by the augmented reality system, the second physical element based on the model; projecting, by the augmented reality system, an image corresponding to the first physical element on or in the second physical element; and validating, by the augmented reality system, whether the first physical element has been correctly installed on the second physical element, wherein validating whether the first physical element has been installed correctly comprises: receiving, by the augmented reality system, an indication from a user via a voice command that the first physical element has been installed; and recognizing, by the augmented reality system, whether the first physical element is in a predetermined installation location on the second physical element, wherein said recognizing, by the augmented reality system, whether the first physical element is in a predetermined installation location on the second physical element comprises: capturing, using the sensor, an image of the first physical element and at least part of the second physical element; and determining, by the augmented reality system and based on the captured image, whether the first physical element has been correctly installed.. receiving, by the augmented reality system, an indication from a user via a voice command that the first physical element has been installed; and recognizing, by the augmented reality system, whether the first physical element is in a predetermined installation location on the second physical element, wherein said recognizing, by the augmented reality system, whether the first physical element is in a predetermined installation location on the second physical element comprises: capturing, using the sensor, an image of the first physical element and at least part of the second physical element; and determining, by the augmented reality system and based on the captured image, whether the first physical element has been correctly installed.. capturing, using the sensor, an image of the first physical element and at least part of the second physical element; and determining, by the augmented reality system and based on the captured image, whether the first physical element has been correctly installed..
