Description

The invention relates to a method for entering characters in a Data processing device and an input medium, in particular for one Computer, with a device for linear analysis of multiple inputs.

Currently, data entry into a computer is common Keyboards used. The data is processed by a central processor processed and secured. However, such conventional keyboards have disadvantages on.

• 1. Today's computers are becoming lighter and more compact, so the size of the computer or other additional parts as small as possible the. However, the keyboard must be designed so that it can be connected to people Lichen finger is adjusted. It is very difficult for a user to find one Use the keyboard when the size of the keyboard is reduced further.
• 2. It is not the cheapest way for a user to type data on a keyboard to enter. Hence a type of computer with a picture frame developed in which the user can write on the picture frame that the user's stroke gesture can distinguish the data to record. However, the input speed and accuracy of such a computer with a picture frame less than one conventional keyboard. The user must also have normal English Use letters or symbols to frame the picture write, otherwise the picture frame will not contain the correct input data can capture, so that the user more time for the input process needed.
• 3. The size of the necessary memory must be increased if the analytical ability of the image is increased so that a computer with Picture frames need more memory to back up or save data to process. A right-angled image processing process can improve clarity increase the image, but it requires more and more memory.

An essential object of the present invention is therefore a Input medium with a device for linear analysis of multiple inputs specify the size of which is kept small, that the input of digits and Symbols are easier and can be adapted to different symbols and numbers.

This object is achieved by the invention specified in claim 1. Advantageous developments of the invention are in the subclaims specified.

The device for linear analysis of multiple inputs has one Azimuth circle that contains a frame line within which there is a baseline and there are a plurality of beam lines. These beam lines extend from the baseline to the outline. The baseline is in a plurality of Sub-baselines divided. The region enclosed by the baseline is one Base region. The region between the frame line and the baseline is the Radiation region, which is divided into eight areas by the beam lines. Of the Operator can make different stroke gestures on the azimuth circle write, each of the touch gestures by area or district going to capture a start intersection and an end intersection so that the azimuth generates two signals to the desired English letters, to achieve Arabic numerals or symbols.

The invention is explained in more detail below using an exemplary embodiment explained. Show it:

Referring to Figures 1 through 7, the present invention includes a device for linear analysis of multiple entries with an azimuth circle 01 which can distinguish various touch gestures thereon to display the desired English letters, Arabic numerals or symbols on a computer screen. The azimuth circle 01 is formed from a frame line 02 , in which a base line 10 and a plurality of beam lines 21-28 are arranged, the beam lines extending from the base line 10 to the frame line 02 . The baseline 10 is also divided into a plurality of sub-baselines 11-18 . The region enclosed by the base line 10 is a base region 03 and the region between the frame line 02 and the base line 10 is a beam region 04 . This is divided into eight areas by the beam lines 21 to 28 , which have a lower area 31 , an area 32 at the bottom right, a right area 33 , a right upper area 34 , an upper area 35 , a left upper area 36 , a left area 37 and form an area 38 at the bottom left.

Referring to Figures 2-5, the present invention enables four types of touch gestures. The reversal stop gesture begins in the beam region 04 and leads back to the beam region 04 via the base region 03 . The rotary stop gesture begins in the beam region 04 and leads over another region of the beam region 04 , and then to the base region 03 . The throw stop gesture begins in the base region 03 , leads through the beam region 04 and then to another area of the beam region 04 . The circulation stop gesture begins in an area of the beam region 04 , leads over the adjacent area of the beam region 04 and then to the next neighboring area of the beam region 04 .

Fig. 2 shows an embodiment of the reverse stop gesture. The stop begins in area 38 at the bottom left and leads through base area 03 to left area 31 of beam region 03 . The stop gesture correspondingly intersects the partial base lines 18 and 11 in order to generate a start point 40 and an end point 41 . This gives the English letter "A" (according to the appendix in FIG. 7). When the reverse stop gesture is reversed, the start and end points are reversed from the original start and end points 40 , 41 so that an entry of the English letter "a" is obtained.

FIG. 3 shows an embodiment of the rotary stop gesture, the stop gesture beginning in the upper left region 36 and leading through the left region 37 of the beam region 04 to the base region 03 . As a result, the stop gesture intersects the base lines 26 and the partial base line 17 in order to generate a start point 42 and an end point 43 , so that the input of the symbol (according to the appendix in FIG. 7) is generated.

Fig. 4 shows an embodiment of the throwing-stop gesture, wherein the gesture stroke begins in the base region 03 and through the upper portion 35 to the upper right region 34 of the beam region leads 04th Therefore, the stop gesture intersects the sub-baseline 15 and the beam line 24 to create a start point 44 and an end point 45 , so that the input of the Arabic number "4" (according to the appendix in FIG. 7) is obtained.

Fig. 5 shows an embodiment of the recirculation stop gesture, wherein the stop gesture in the upper portion 35 begins, and by the right upper area 34 to the right portion 33 of the beam region, leads 04 so that the stop gesture 24 and 23 intersects the beam lines to a starting point 46 and to generate an end point 47 , whereby the input of the symbol "]" (according to the system in FIG. 7) is achieved. If the circular stop gesture is operated in reverse, the entry of a symbol "]" can also be achieved.

Fig. 7 is an illustration of the intersections of various stroke gestures on the azimuth circle to produce different English letters, Arabic numerals or symbols according to ISO 2022, the starting points with a "⚫" and the end points with a "∆", if the Azimuth circle contains only two starting points "⚫", which means that the touch gesture can be used reversibly and generates the same input data.

Figure 6 is a flow chart illustrating the method of operation of the invention. The linear analysis begins in block 50 , a starting point being reachable by an input signal 51 . An end point can be achieved by another input signal 52 . Start and end points can be checked by a decision process 53 . If these two intersections fall on the same line, the system jumps back to step 52 . If not, the system goes to the next decision process 56 . Decision process 56 can check whether start and end points intersect the same segment baseline or a different segment baseline. If so, the system can generate an English letter, 57 (reverse stroke gesture). If not, the system proceeds to the next decision process 58 . Decision process 58 can determine whether the start point and the end point are separated from a segment baseline and a ray line. If this is the case, the system can generate an output of a symbol (the rotary stop gesture or the circular stop gesture). If not, the system proceeds to the next decision process 59 . The decision process 59 can check whether the start point and the end point are separated by a beam line. If so, the system can generate the output of an Arabic numeral (the throw-ray gesture), if not, the system can jump to an end process 60 and back to the start process 50 .

The description above is only intended to illustrate one Embodiment. The invention is not limited thereto and also includes Changes and modifications to the invention specified in the claims.
