The detection of relative motion or orientation between a user and a computing device can be used to control aspects of the device. For example, the computing device can include an imaging element and software for locating positions, shapes, separations, and/or other aspects of a user's facial features relative to the device, such that an orientation of the device relative to the user can be determined. A user then can provide input to the device by performing actions such as tilting the device, moving the user's head, making a facial expression, or otherwise altering an orientation of at least one aspect to the user with respect to the device. Such an approach can be used in addition to, or as an alternative to, conventional input devices such as keypads and touch screens.

Linvention concerne la détection dun mouvement relatif ou dune orientation relative entre un utilisateur et un dispositif de calcul, la détection pouvant être utilisée pour commander des aspects du dispositif. Par exemple le dispositif de calcul peut comprendre un élément dimagerie et un logiciel de localisation de positions, de formes, de séparations et/ou dautres aspects de caractéristiques faciales dun utilisateur par rapport au dispositif, de telle sorte quune orientation du dispositif par rapport à lutilisateur peut être déterminée. Un utilisateur peut alors fournir une entrée dans le dispositif par lexécution dactions telles que linclinaison du dispositif, le déplacement de la tête de lutilisateur, lexécution dune expression faciale ou autrement la modification dune orientation dau moins un aspect de lutilisateur par rapport au dispositif. Une telle approche peut être utilisée en plus des dispositifs dentrée classiques tels que des pavés numériques et des écrans tactiles, ou en variante à ceux-ci.
