A computing device () for authenticating a user () is provided. The computing device is operative to display a first text () to the user, acquire a representation of the user subvocalizing a part of the first text, derive a user phrasing signature from the acquired representation, and authenticate the user in response to determining that the user phrasing signature and a reference phrasing signature fulfil a similarity condition. Optionally, the computing device may be further operative to determine if the user is authorized to read the first text. Further optionally, the computing device may be operative to reveal obfuscated parts of the first text in response to determining that the user is authorized to read the first text, or to discontinue displaying the first text, or to obfuscate at least part of the first text, in response to determining that the user is not authorized to read the first text.

A method and an apparatus for enabling adaptive audio signal alteration are described. When an input audio signal is received, a determination of whether the user of an audio device hears the input audio signal is performed based upon brain activity of the user. A determination of whether the user is distracted by the audio signal is performed based upon sensor measurements indicating a physical state of the user. In response to determining that the user hears the input audio signal and that the input audio signal causes the user to be distracted, a determination of configuration parameter(s) is performed. An alteration of audio signal(s) is caused based upon the configuration parameter(s) to obtain modified version(s) of the audio signal(s) that are intended to address the distraction caused by the input audio signal, and output audio signals are output, where the output audio signals include the modified versions.

A method and a communication device for changing the shape of a flexible communication device is suggested. The suggested method is initiated by recognizing a request for actuating a haptic effect on the communication device. At least one property associated with the requested haptic effect, and at least one property of the communication device, where the latter is being caused by the shape of the communication device, are determined. Based on the mentioned properties, a determination is made on whether conditions, specifying requirements for reproducing the haptic effect on the communication device, are met or not. In case the mentioned conditions are not met, a modification of the shape of the device is determined, such that after such a modification the conditions are met with respect to the mentioned properties.
