Other advantages and features will become apparent upon consideration of the detailed description of non-limiting embodiments, and the accompanying drawings, in which: FIG. 1 is a schematic representation of an embodiment of a device of FIG. display according to the invention; and FIG. 2 is a diagrammatic representation in the form of a diagram of a method according to the invention.

In the figures and in the following description, the elements 5 common to several figures retain the same reference.

FIGURE 1 is a schematic representation of an embodiment of a display device according to the invention. The device 100, shown schematically in FIG. 1, comprises a display module 102 controlling a circular display screen 104. The display module 102 includes a sensor element 106 arranged to measure the angle of rotation of the screen 104. The device 100 includes an adjustment module 108 adjusting the display angle of an image / datum to display received from a generation module 110 generating the image / data to be displayed. The angle of rotation measured by the sensor element 106 is compared by the adjustment module 108 to a predetermined angle for a predetermined predetermined display direction relative to the screen 104. The adjustment module 108 receives from the part of the generation module 110 the image / data to be displayed. The image / data to be displayed is generated for display at a default angle. This default angle may correspond to the predetermined direction when the screen 104 is in the home position, i.e., when it is turned neither in one direction nor the other. The display angle is modified by the adjustment module 108 as a function of the rotation angle of the screen 104, so that the image / data is displayed in the predetermined direction regardless of the angle In practice, the adjustment module 108 determines the difference A between the predetermined direction represented by the line 112, with respect to the rotation angle of the screen 104 represented by the straight line 114. This difference is then subtracted at the default display angle (3) and thus the data / image is displayed in the predetermined direction 112. The data / image to be displayed is thus displayed with an angle [3-A .

The device 100 further comprises a module 116 for detecting a position of a tactile selection made on the screen 104. This position, said previous, detected is then communicated on the one hand to the generation module 110 for the generation a new data / image to be displayed and secondly to the adjustment module 108. The position, said next, of the new data / image to be displayed is adjusted by the adjustment module 108 as a function of the position previous so that the new data / image is displayed near or in the same position as the previous position. Concretely, the previous position is a set of two values (X, Y). The data / image to be displayed is generated by the generation module 110 with a default position, for example (A, B). The adjustment module 108 adjusts the values A and / or B so that A = X or X 'and / or B = Y or Y', with X 'and Y' very close to or equal to x and Y respectively. The position sensing module 116 of a touch selection may further be arranged to detect the so-called current position of a user's hand or finger at the edges of the screen 104 so that the position of the image / data to be displayed is also adjusted according to this current position.

FIGURE 2 is a diagrammatic representation in the form of a diagram of an exemplary method according to the invention. The method 200 shown in Figure 2 comprises a step 202 of generating a data / image to be displayed. In a step 204 an angle of rotation of the screen is measured with respect to a predetermined direction. The measured angle is compared with the angle of the predetermined direction in a step 206. If the measured angle is not different from the angle corresponding to the predetermined direction no adjustment of the display angle is not realized. If the angle measured is different from the angle corresponding to the predetermined direction, the difference A between the measured angle and the angle corresponding to the predetermined direction is determined. In a step 208 the position of the previous touch selection is determined. The data (X, Y) corresponding to this previous touch selection is stored. According to the difference of angle A, and of the position data (X, Y), a step 210 adjusts the angle and the display position of the data / image to be displayed. This step 210 includes a sub-step 212 adjusting the display angle and a sub-step 212 adjusting the display position. The image / data thus adjusted is then sent to the screen for display at step 216.

Of course, the invention is not limited to the examples which have just been described.
