The present invention is directed to a portable device (10) and a method for using such a device, which device comprises a touch sensitive arrangement (20, 20a, 20b, 20c, 20d, 42) comprising; a touch-surface (22a, 22b, 22c, 22d) arranged to be operatively actuated and to operatively receive touches from a user of the device (10), an actuator arrangement (30a, 30b, 30c, 30d) arranged to operatively actuate at least a part of said touch-surface (22a, 22b, 22c, 22d), a control arrangement (40, 42) arranged to operatively detect touches on said touch-surface (22a, 22b, 22c, 22d) and to operatively control said actuator (30a, 30b, 30c, 30d) to actuate said touch-surface (22a, 22b, 22c, 22d) so as to provide a perceivable feedback to the user as a response to a detected touch. The actuator arrangement (30a, 30b, 30c, 30d) comprises an electroactive polymer arrangement (30aa, 30ab, 30ac; 30ba, 30bb, 30bc; 30ca, 30cb, 30cc; 30aa, 30ab, 22b) arranged to be operatively actuated by said control arrangement (40, 42) so as to actuate said touch-surface (22a, 22b) for providing a perceivable feedback to the user as a response to a detected touch. |
