Embodiment Construction

[0035] exist figure 1 The method shown in for displaying a virtual keyboard on a mobile terminal 1 involves the detection of a change in the position of the mobile terminal 1 in the direction of one of the three spatial axes.

[0036] In a first method step, the mobile terminal 1 acquires image data 3 at a first camera position 2 by means of its integrated camera.

[0037] In a second method step, the image data 3 at the camera position 2 are stored, as in the prior art, according to the formed priority-assigned pixel groups 4 . Wherein according to methods known in the prior art, the group of pixels with the highest priority automatically represents the corresponding area of ​​the image.

[0038] In a third method step, the position value 9 of the assigned pixel group 4 at the first camera position 2 is stored in the mobile terminal 1 .

[0039] If the camera 2 is moved in the direction of one of the three spatial axes to the second camera position 5 , the position value 9 ...

Abstract

The invention relates to a method for representing a virtual keyboard on the display of a mobile terminal, as for example a cell phone, wherein the mobile terminal comprises a camera for capturing image data, a display for representing the image data and a keyboard for selecting menu functions or for inputting, for example, a text message The invention is characterized in that the keyboard is designed as a virtual keyboard on the display of the mobile terminal and that a cursor represented on the virtual keyboard is designed to the moveable, wherein the cursor moves according to the movementsof the mobile terminal in the spatial axes to the corresponding keyboard field of the virtual keyboard.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for displaying a movable keyboard or a movable indicator (cursor) on a display of a mobile terminal. Background technique [0002] Mobile terminal devices, such as "mobile phones", have more and more functions today, such as camera and video functions, wherein the size of "mobile phones" should be as small as possible for users. For this reason, the size of mobile terminal devices is getting smaller and smaller. [0003] However, there are problems here with regard to operability, especially when entering text, for example SMS (Short Message Service), on ever smaller keyboards. [0004] There are currently many different possible ways of entering text, which are categorized below: [0005] - Entering text via a full-value mini-keyboard, such as an MDA (Monochrome Display Adapter), where this input function has the disadvantage of having keys that are too small and leads to incorre...
