Description

Input device with switchable cursor mode and writing mode

technical field

The utility model relates to an input device, in particular to an input device with a switchable cursor mode and a writing mode whose operation is more in line with the use requirements.

Background technique

Ordinary desktop computers or notebook computers can be used with an external drawing/handwriting tablet or a built-in touch panel, according to the movement track of the touch point, plus pressing the left mouse button or a function key equivalent to the left mouse button , to output vector coordinates and form lines. However, when the current drawing/handwriting board or touch panel moves the cursor, it always sends the movement vector of the touch point, and does not memorize and inform the computer when the pen is picked up and down between strokes. The position and the gap, referring to Fig. 1, that is to say, when the user draws the track of a line I on the drawing/handwriting board or the touch panel 5 by a stylus or a finger and lifts the pen at position I1, for the computer Therefore, when the user draws another line II at position II1 next time, the line II will be formed from position I1 instead of from position II1. Start to form line II. This situation is as if using the mouse to move the cursor to a certain point. At this time, if the mouse is picked up, put down and moved again, the cursor will still stay at the fixed point and start moving from the fixed point. Therefore, it is not easy to control the strokes that cause lines, and of course it is impossible to write a font easily.

Therefore, a kind of application software that can solve the above-mentioned deficiencies was born accordingly. This application software is mainly executed on desktop computers or notebook computers, and can be used with an external drawing/handwriting tablet, or directly with the touch screen of a notebook computer. The panel makes the moving track of the touch point and the screen have a ratio of 1:1, that is to say, the cursor moves according to the coordinate value of an absolute coordinate, thereby making the lines or handwritten fonts easier to manipulate. However, although the above-mentioned touch panel and drawing/handwriting pad can cooperate with software to make the computer operate in cursor mode or handwriting mode, there are still the following deficiencies in actual use that need to be solved urgently:

With the popularization of computers and the increasing communication, today's computer peripherals all emphasize the convenience of plug and play, that is to say, after a peripheral is preferably connected to any computer, it does not need to be installed. It can be operated and used without driver or matching software, so whether it is a built-in touchpad of a notebook computer or an external touchpad

For drawing\handwriting boards, you must first install the matching software before you can start using them, which cannot achieve true plug-and-play. Therefore, the aforementioned touchpads or drawing\handwriting boards still have room for improvement in terms of ease of use. Space.

Detailed ways

As shown in FIG. 2 , FIG. 3 , and FIG. 4 , the input device capable of switching cursor mode and writing mode of the present invention includes a housing 1 , a switching unit 2 , a touch unit 3 and a control unit 4 . Mainly to control the computer (not shown) to execute related actions.

The switching unit 2 has a switching key 21 arranged on the housing 1 .

The touch unit 3 has a pressure touch panel 31 disposed on the casing 1 , and a stylus 32 .

The control unit 4 is arranged in the casing 1 and is electrically connected with the switch unit 2 and the touch unit 3 , mainly for signal processing and transmission according to the execution functions of the switch key 21 and the touch unit 3 . The control unit 4 is mainly composed of a microprocessor 41 with programming to establish its action program, an input connector 42, an output connector 43, a switch 44 and a clock unit 45 and the like. The microprocessor 41 is connected to the input connector 42 with the pins 411, 412, 413, 414, connected with the output connector 43 with the pins 415, 416, 417, with the pin 418 as the ground terminal GND, and with the pin 419 and The switch 44 is connected, and the pin 410 is connected with the clock unit 44 .
