Description

Keyboard with integrated cursor commands

The invention relates to a keyboard, particularly a keyboard integrating cursor commands.

With the advancement of technology and the popularization of computers, using computers to process homework reports, work materials, watch programs, or play games has become an indispensable part of modern people's daily lives.

A general computer usually includes a computer host, a display screen, and an input device. The input device includes a keyboard for people to input data or use shortcut keys, and a mouse that can intuitively operate the cursor on the display screen.

However, modern people use computers for a long time, and in the long run they are prone to mouse hand injuries, which is also known as carpal tunnel syndrome in medicine. This hand injury is mainly caused by the patient's hand leaning on the table for a long time to move the mouse. It is caused by keeping the wrist in an unnatural posture. This will not only compress the ligaments or nerves near the wrist for a long time, but also keep the fingers holding the mouse in the same posture for a long time. Over time, hand fatigue, numbness, and swelling will occur. Uncomfortable symptoms such as pain or tingling.

In view of this, long-term use of the mouse will cause discomfort to the user's hand. It is obvious that the computer input device of the conventional technology still has room for improvement. Therefore, the creator of this project believes that it is necessary to devise a device that can effectively improve the user's actual operating experience. and sensory input devices.

The main purpose of this invention is to provide a keyboard that integrates cursor commands and is connected or coupled to the host and/or the display. The keyboard includes a composite keypad, a composite Function switch button, and a microcontroller electrically connected to the composite key area and the composite function switch button. Pressing the composite function switch button and any button in the composite key area simultaneously triggers the execution of the task. The cursor command corresponding to a key is used to control the cursor, and releasing the composite function switch key switches back to triggering the execution of the key command corresponding to any key.

Further, the microcontroller uses the pressed key code to allow the host to identify the key command corresponding to the pressed key.

Further, the keyboard includes an integrated key area electrically connected to the microcontroller. The microcontroller defines any key in the integrated key area as a composite function switch key. The integrated key area includes a Space key, multiple character keys, or multiple function keys.

Further, the composite key area includes a central key and a plurality of peripheral keys arranged around the central key.

Further, the central button is marked with a number 5, and pressing the composite function switch button and the central button simultaneously triggers execution of the cursor command of clicking the mouse wheel.

Further, with the central button as the center, eight peripheral buttons marked with numbers 1 to 4, 6 to 9 are arranged in eight directions around the central button, and the composite function switch button is pressed simultaneously, and One of the peripheral keys triggers execution of the cursor instruction for moving the cursor.

Further, on the side of the peripheral button marked with the number 2, there are three peripheral buttons marked with the number 0, the number 00, and the decimal point symbol respectively. Press the composite function switch button and the number 0 marked at the same time. The peripheral button triggers the execution of the cursor command of clicking the left mouse button, or pressing the composite function switch button and the peripheral button marked with a decimal point simultaneously triggers the execution of the cursor command of clicking the right mouse button, and Or press the composite function switch button and the peripheral button marked with the number 00 at the same time to trigger the automatic scrolling. This cursor instruction of the wheel.

Further, on the side of the peripheral button marked with the number 8, there are two peripheral buttons marked with a division symbol and a multiplication symbol respectively. Press the composite function switch button and the peripheral button marked with a division symbol at the same time. , it triggers the execution of the cursor instruction to return to the previous page, or pressing the composite function switch button and the peripheral button marked with the multiplication symbol simultaneously triggers the execution of the cursor instruction to return to the next page.

Further, on the side of the peripheral button marked with the number 6, there are two peripheral buttons marked with an addition symbol and Enter, respectively. Press the composite function switch button and the peripheral button marked with an addition symbol at the same time. The cursor instruction to move the manual wheel up is triggered, or the composite function switch button and the peripheral button marked Enter are pressed simultaneously to trigger the cursor instruction to move the manual wheel down.

Further, a peripheral key marked with a subtraction symbol is provided on one side of the peripheral key marked with an addition symbol. Pressing the composite function switch key and the peripheral key marked with a subtraction symbol simultaneously triggers the execution of adjusting the cursor sensitivity. of this cursor instruction.

Therefore, by pressing the composite function switch button and any button in the composite key area at the same time, this invention can completely replace the mouse for cursor operation, and release the composite function switch button to switch back to the original keys in the composite key area. operation, effectively improving the user’s operating experience.

There may be a plurality of cursor sensitivity modes, and the switching between modes may be a cycle. In one embodiment, the cursor sensitivity modes include a low sensitivity mode and a high sensitivity mode. When switching in the low sensitivity mode, the cursor sensitivity mode is switched to the high sensitivity mode, and if the switch is continued, the cursor sensitivity mode is returned to the high sensitivity mode. In another embodiment, the cursor sensitivity mode includes five segments, and the mode can be switched from one segment to five segments in sequence, and when the five segments are switched, it can be returned to one segment, and the aforementioned process can be repeated by switching again. cycle. Yu Youyishi In this example, the difference from the previous embodiment is that when switching in the fifth stage, the system can sequentially switch to the fourth stage in descending order, and finally switch back to the first stage, and then switch again to repeat the aforementioned sequence of switching from the first stage to the fifth stage. cycle. In this creation, there is no limit on the number of cursor sensitivity modes or the loop method, which will be explained here.

To sum up, by pressing the composite function switch button and any button in the composite key area at the same time, this creation can completely replace the mouse for cursor operation, and release the composite function switch button to switch back to the original composite key area. The key operation effectively improves the user's operating experience.

The present creation has been described in detail above. However, the above is only one of the preferred embodiments of the present creation. This cannot be used to limit the scope of the present creation, that is, any equivalent changes made in accordance with the requirements of the present creation. and modifications should still fall within the scope of the patent for this creation.
