Controller For Controlling An Electronic Device

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 (1) comprises an elongate controller body (3) having a first body end (4) and a second body end (5). The controller body (3) comprises an elongate rotatable body section (10) adapted to be rotated by a user about a longitudinal axis (11) extending through the first body end (4) and the second body end (5). The rotatable body section (10) has a radially outer side surface (12) extending between a first section end (13) near the first body end (4) and a second section end (14) near the second body end (5). The rotatable body section (10) has a size and shape allowing the user to rotate the rotatable body section (10) about the longitudinal axis (11) by performing a rolling action using three or more fingers (21, 22, 23). The controller (1) further comprises a sensing means (30) adapted to detect a rotation of the rotatable body section (10) about the longitudinal axis (11) and to provide a control signal (Sc) indicating one or more control commands to the electronic device in dependence on detecting a rotation. The controller (1) is characterized in that the sensing means (30) further is adapted to distinguish between a three-finger rolling action and a corresponding two-finger rolling action and to provide the control signal (Se) in dependence on detecting a three-finger rolling action. This may provide a controller (1) 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.
