Claim 12:
13. A device comprising:
a housing;
a roll unit mounted in the housing and configured to be rotatable around a roll axis;
a flexible touch-sensitive display configured to be rolled around said roll unit and to define a planar front screen having a fixed first dimension and a second dimension that changes according to a degree of rotation of said roll unit;
a controller configured to control said display to display a visual content on said front screen, and to adapt at least one dimension of said visual content to match a corresponding dimension of said front screen;
an accelerometer connected to said controller and configured to detect movement gestures of said display;
wherein said front screen is configured to be adjusted by said controller between a rolled-in state in which said second dimension is minimal, and a rolled-out state in which said second dimension is maximal;
wherein the controller is further configured to:
in response to the accelerometer detecting a first movement gesture, adjust said front screen to a rolled-out state; and
in response to the accelerometer detecting a second movement gesture, adjust said front screen to a rolled-in state;

wherein said first movement gesture comprises:
a first sub-gesture of arranging said display in a horizontally upwards state, and
a second sub-gesture of shaking said display by rotating in a clockwise direction around an axis parallel to said roll axis while keeping said display upwards and returning the display to said horizontally upwards state;

wherein said second movement gesture comprises:
said first sub-gesture; and
a third sub-gesture of shaking said display by rotating in a counter-clockwise direction around an axis parallel to said roll axis while keeping said display upwards and returning the display to said horizontally upwards state; and

wherein said controller is configured to:
detect a time interval Td elapsed between said first sub-gesture and said second sub-gesture or said third sub-gesture, to
interpret said first movement gesture valid only if said time interval Td between the first sub-gesture and the second sub-gesture is equal or shorter than a predefined time threshold Tr, and to
interpret said second movement gesture as valid only if said time interval Td between the first sub-gesture and the third sub-gesture is equal or shorter than a predefined time threshold Tr.
