Orthogonal press-key locating rapid retrieval method based on handhold reading device

Abstract

The invention belongs to the information technical field and provides a handholding reading device based orthogonal keypress rapid retrieval method. The method utilizes a method of combining horizontal and vertical orthogonal keypresses of a handholding reading device to concentratively retrieve bottom data elements from data elements with directory index structure and displays the bottom data elements on a screen. The method has the advantages of easy and flexible operation and rapid retrieval, reduces the stimulation to human eyes caused keypress scrolling and improves the applicability and comfort of handholding reading device. Meanwhile, the method reduces the key pressing times in the process of retrieval, thereby saving power consumption, hence the method is applicable to handholding reading devices with high requires of power consumption norms.

Description

technical field [0001] The invention belongs to the field of information technology, in particular to a fast retrieval method for orthogonal key positioning based on a handheld reading device. Background technique [0002] With the rapid development of Internet technology, a large number of digital content can be disseminated quickly, followed by people's increasing demand for electronic reading methods, especially handheld reading methods, so various Handheld reading devices, such as: handheld e-readers, personal digital assistants, electronic dictionaries, learning machine products and large-screen mobile phones, etc. When using this type of handheld reading device to read manual files such as electronic dictionaries and reference books stored therein, you should be able to quickly retrieve the content you are looking for; in addition, when reading a digital file in a directory with multiple files When adding content resources, you should also quickly retrieve the files y...

AI Technical Summary

Problems solved by technology

In the present processing method, when carrying out the above-mentioned retrieval or reading, generally all content will be displayed on the screen, and a single button is used to select. Often, when retrieving an entry or content, it is necessary to repeat the button several times to retrieve the selected content. It is shown that this method is complicated to operate, which not only delays the time, but also increases the power consumption of the product

[0003] In view of the problems in the above method, one method is to reduce the number of keystrokes by increasing the screen size to increase the number of display elements on the screen, but this method will increase the cost and power consumption with the increase of the screen size, and The decline of portable performance; another method is to use the touch screen, which can simplify the complexity of operation, but the design of the touch screen will inevitably increase the power consumption of the product and increase the cost of the equipment

The above methods do not fundamentally solve the problem of fast retrieval and positioning of the content to be read by the handheld reading device, and there are problems such as inconvenient operation, slow retrieval speed, and high power consumption of the device.
