Controller for controlling an electronic device

Abstract

The present invention relates to a controller for controlling an electronic device. The invention may e.g. be used to control a headset or another electronic device connected to the controller. The controller () comprises an elongate controller body () having a first body end () and a second body end (). The controller body () comprises an elongate rotatable body section () adapted to be rotated by a user about a longitudinal axis () extending through the first body end () and the second body end (). The rotatable body section () has a radially outer side surface () extending between a first section end () near the first body end () and a second section end () near the second body end (). The rotatable body section () has a size and shape allowing the user to rotate the rotatable body section () about the longitudinal axis () by performing a rolling action using three or more fingers (). The controller () further comprises a sensing means () adapted to detect a rotation of the rotatable body section () about the longitudinal axis () and to provide a control signal (S) indicating one or more control commands to the electronic device in dependence on detecting a rotation. The controller () is characterized in that the sensing means () further is adapted to distinguish between a three-finger rolling action and a corresponding two-finger rolling action and to provide the control signal (S) in dependence on detecting a three-finger rolling action. This may provide a controller () with a significantly reduced rate of 'false alarms' as well as an unobtrusive, reliable and at the same time simple and easy-to-use interface to the user.
