Abstract
The invention relates to a method of giving the user information on the operation of a portable device, and a portable device. In the method, an event that concerns the operation of the device and interests the user is detected (302) by the control means of the device. If at least one silent alarm pattern producing a tactile sensation in the user is attached to the event, the user is given (312) abstract information on the operation of the device by using at least one silent alarm pattern implemented with the alarm device and sensed by the user. Various alarm patterns differ from one another such that at least one alarm pattern characteristic sensed by the user varies. The characteristic can be the alarm pattern frequency, amplitude, changing rate of the amplitude, changing rate of the frequency or duration of the alarm pattern. One way to perform a silent alarm is vibration. The user interface is particularly intended for users with impaired hearing and/or vision.
