Title
(EN) SENSING AUDIO INFORMATION AND FOOTSTEPS TO CONTROL POWER
(FR) DÉTECTION D'INFORMATIONS AUDIO ET DE PAS POUR COMMANDER LA PUISSANCE
Abstract
(EN)
A method, according to one example, includes sensing audio information with an audio microphone of a computing device. The method includes determining, by a controller of the computing device, whether the sensed audio information indicates footsteps moving toward the computing device. The method includes causing, by the controller, a powering up of a presence sensor having a higher power consumption than the microphone in response to a determination by the controller that the sensed audio information indicates footsteps moving toward the computing device.
(FR)
La présente invention concerne un procédé, selon un exemple, qui comprend l'étape consistant à détecter des informations audio avec un microphone audio d'un dispositif informatique. Le procédé comprend l'étape consistant à déterminer, par un contrôleur du dispositif informatique, si les informations audio détectées indiquent des pas se déplaçant vers le dispositif informatique. Le procédé comprend l'étape consistant à entraîner, par le contrôleur, l'activation d'un capteur de présence ayant une consommation d'énergie supérieure à celle du microphone en réponse à une détermination par le contrôleur que les informations audio détectées indiquent des pas se déplaçant vers le dispositif informatique.
