Contextual display

Abstract

A method for controlling content on a display of an electronic device includes emitting from an ultrasound transducer located in the electronic device, a first ultrasound signal at least some portion of which is directed towards the user. The method also includes receiving a second ultrasound signal at a receiver transducer located in the electronic device. The second ultrasound signal includes a portion constituted by a the first ultrasound signal being reflected from the user face. The method also includes computing a distance between the user and the electronic device using acoustic measurements involving at least one acoustic transducer. The electronic device includes a memory storing at least two sets of predetermined display features. The electronic device is set to display a first set when the distance between the electronic device and the user is above at least one chosen threshold and the second set of display features when the distance is less than the threshold.
