Problems solved by technology

When it is necessary to input characters by handwriting recognition, it is necessary to press down the handwriting button grid 110 to change the surface of the induction plate into the handwriting screen 102 before continuing to input, which is quite inconvenient to use.

Embodiment Construction

[0030] Because in the traditional Personal Digital Assistant (PDA) system, the handwriting input board and the virtual keyboard each use the sensing device independently, so the use of the panel is quite uneconomical. And if the traditional personal digital assistant system needs to input special symbols on some keyboards and input characters in the mode of handwriting recognition, the input person must always press the handwriting button grid to distinguish between the handwriting recognition input method and the keyboard type input method. do the switch. Therefore, the present invention provides a personal digital assistant system with a direct input mode, which can input special symbols on the keyboard as well as recognize and input by handwriting. Moreover, the handwriting input area of ​​the personal digital assistant system overlaps with the keyboard input area, which saves the area of ​​the whole device.

[0031] When the present invention is used in a personal digital...

Abstract

An input device integrating handwriting recognition input with virtual keyboard input is composed of position cell converter for generating the first cell by associating the touch point with relativecell, trace cell converter for generating the second cell by associating the trace with relative cell, position-trace signal converter containing the switching area on its surface for generating the first or the second cell, and input switching unit for switching the output of position-trace signal converter to position cell converter or trace cell converter.

Description

technical field [0001] The invention relates to an input device for a computer system, in particular to an input device integrating handwriting recognition input and virtual keyboard input. Background technique: [0002] In general computer systems, there are two commonly used input methods, keyboard input and handwriting recognition input. Generally speaking, if the device used for traditional keyboard input is not a physical keyboard, it is a virtual keyboard. The physical keyboard is a general button-type keyboard, while the virtual keyboard uses a sensor board, and the sensor board has regions representing characters on each keyboard. When the user touches a certain area, the characters corresponding to this area will be displayed on the display. [0003] The principle of handwriting recognition input is that the user directly writes the characters to be input by hand on the sensor board of the handwriting recognition input. After the trajectory generated by the signal...
