Definitions

• the invention relates to a method for displaying a movable keyboard or a movable pointer (cursor) on the display of a mobile terminal according to the preamble of claim 1.
• Mobile devices such as a "cell phone”
• functions such as camera and video function
• the dimensions of the “mobile phone” should be as small as possible on the part of the operator. For this reason, the mobile terminals are getting smaller in size.
• Keyboard is displayed on the screen.
• this input function has the disadvantage that the representation of a keypad has a relatively large footprint.
• a menu navigation of current mobile terminals for entering text is based in part on text or icon (icon), which are selected for example by means of a scroll wheel or a multifunction button.
• the multifunction knob offers the option of moving the menu cursor (cursor) to the left, right, up or down and confirming the selection by pressing the multifunction knob. Intermediate areas are not provided due to the mechanics used.
• An example of this is the overlaying of a photograph with, for example, a crosshair to indicate the central orientation of an image.
• the main disadvantage of this aforementioned application is the large storage requirement for storing image data.
• the object of the present invention can thus be seen to further develop a mobile terminal such that the input of texts via a keypad, the size of which is formed independently of the dimensions of the mobile terminal.
• the invention is characterized by the features of the independent claim 1.
• the method represents the keyboard as a virtual keyboard on the display of the mobile terminal and one above the virtual terminal Keyboard shown pointer (cursor) forms movable with the pointer (cursor) moves according to analogous to the executed in the spatial axes movements of the mobile device to the corresponding keyboard field of the virtual keyboard.
• a method known from the prior art for compressing and decompressing such image data is disclosed by the publication DE 101 13 880 A1, wherein the method of prioritizing pixel groups is used to display images, such as a keyboard, with a Camera recorded image data having a matrix of individual pixels (pixels), which have a temporally variable pixel value, the color or brightness information of the pixel describes. Each pixel is assigned a priority and sorted according to this priority in the matrix. The pixels and pixel values are transmitted and stored, with one pixel having a high priority when the distance to the neighboring pixel is large. In a reconstruction, only the current pixel values are shown, wherein not yet transferred pixels are calculated from already transmitted pixels.
• a camera is used to record the required image data, as is currently the case in most mobile terminals, such as in a "mobile phone".
• a control knob is provided, which confirms the selection, for example by pressing.
• a cursor is displayed on the display, which cursor is movable by movements of the mobile terminal (mobile phone) in the spatial axes in the analog direction in the display of the mobile terminal.
• the recorded images of the camera are evaluated according to the known from the prior art method for compression and decompression of image data.
• a keyboard can be saved in a mobile terminal, such as in a cell phone, the housing of the device can be smaller, or the display can be made larger.
• Figure 1 a schematic flow diagram of the method according to the invention
• the method illustrated in FIG. 1 for displaying a virtual keyboard in a mobile terminal 1 is aimed at detecting the change in position of the mobile terminal 1 in the direction of one of the three spatial axes, thereby generating a virtual movement of a pointer (cursor) displayed above the virtual keyboard becomes.
• the mobile terminal 1 captures image data 3 in the first camera position 2 by means of its integrated camera. These image data 3 of the camera position 2 are stored in a second method step corresponding to formed, phorized pixel groups 4 according to the prior art.
• the highest-priority pixel groups automatically describe the relevant areas of an image.
• the position values 9 of the prioritized pixel groups 4 of the first camera position 2 are stored in the mobile terminal 1.
• the position values 9 of the formed prioritized pixel groups 4 likewise change in a corresponding manner.
• the image data 7 are acquired at the second camera position 5, wherein in a fifth method step the prioritized pixel groups 8 with the associated position values are formed at the camera position 5.
• the position values 10 of the formed prioritized pixel groups 8 at the camera position 5 are compared with the position values 9 of the formed prioritized pixel groups 4 of the camera position 2.
• the highest priority pixel groups A1, B1 and C1 at the camera position 2 are determined at positions a1, b1 and d of a matrix.
• A1, B1 and C1 are prioritized in such a way that the pixel values of A1, B1 and C1 additionally differ greatly.
• the displacement of the positions of a1, b1 and d of the camera position 2 to the positions a2, b2 and c2 of the camera position 5 are directly related to the movement of the mobile terminal 1.
• a cursor is moved 12 on the display of the mobile terminal 1.
• Control button a keypad with an associated letter on which the
• Cursor is currently being selected for selection.
• the subsequently acquired images such as, for example, in the camera position 5 are no longer complete but only in the vicinity of the already found pixel groups 8 evaluated. In this way, complex computing time and thus battery life is saved.
• an additional camera light is used to detect the movements of the mobile terminal 1.
• additional menu functions may be opened or closed, such as the selection of special characters (@ or ⁇ or the like).
• Both linear and non-linear movements can be performed to move a cursor quickly over larger display areas.
• a parallel displacement of the mobile terminal 1 on a surface leads to a linear displacement of the cursor on the display.
• Non-linear displacements of the cursor are generated, for example, by an additional rotational movement of the mobile terminal 1.
• a software-based screening is used to select the letter / menu item of the respective keypad safely.
• the cursor may also be fixedly positioned on the display, whereby the selection fields, such as the keyboard fields of a virtual keyboard, shift according to the movement of the mobile terminal 1.
• mobile terminal e.g., mobile phone
• Image data of the second camera position 8. Forming prioritized pixel groups of the second camera position with the associated position values
