Problems solved by technology

[0004] However, when using the above-mentioned resistive touch screen, the user often needs to apply pressure on the touch screen, which makes the touch screen easy to be damaged. In addition, due to factors such as material aging, the user often needs to apply a lot of pressure. times, touch the screen to respond
Also, since the resistive touch screen has been combined with a liquid crystal display (LCD), when the resistive touch screen ages, it is very difficult to update it.

Embodiment Construction

[0044] FIG. 1 is a schematic diagram of using the surface-sensing input device with index data of the present invention in a computer system, which includes a host device 100 , a surface-sensing input device 200 and an optical reading device 300 . In this embodiment, the surface-sensitive input device 200 is a display, which is connected to the host device 100 so that the host device 100 outputs data on the screen 400 of the display 200. The screen of the surface-sensitive input device 200 400 is also divided into a plurality of areas (810, 811), each area has a plurality of index points (610, 611), each index point (610, 611) represents the code of the corresponding area, and these index points use specific optical The reading device 300 can read the printed material. The optical reading device 300 is connected to the host device 100 and used for reading the index points on the screen 400 , so as to hand over the read index points ( 610 , 611 ) to the host device 100 for proc...

Abstract

The present invention relates to a computer system. It includes a host machine device, a display and an optical fetch device. Said display is connected with said host machine device to make host machine device output data on the screen of said display, its surface inductive input device also can separate it into several regions, every region has several index points, every index point can represent code correspondent to said region, these index points can use specific optical fetch device to fetch data. Said optical fetch device is connected with the host machine device for fetching the above-mentioned index points, these index points can be processed by sand host machine.

Description

technical field [0001] The invention relates to a surface-inductive input device with index data, especially a surface-inductive input device with isodirectional index data and a computer system using the surface-inductive input device. Background technique [0002] Generally, input devices can be classified into keyboards, touch screens, and handwriting pads. However, due to the limitations of the keyboard, for non-English input (for example: Chinese input), the touch screen and handwriting pad are easier for users to accept than the keyboard. [0003] Touch screens are available in resistive type, capacitive type, ultrasonic wave type, optical sensing type, electromagnetic type and other similar types. The resistive touch screen has been combined with a liquid crystal display (LCD), and is widely used as an input device in electronic notebooks, personal digital assistants (PDAs), portable personal computers, and the like. When compared with other types of touch screens, ...
