Rotary type continuously speed changing browsing and search method based on touch screen

Abstract

The invention discloses a touch screen-based rotary type continuous speed changing browsing and searching method, belonging to the information technical field; with the method, a user can make continuous operations in the limited ranged of the touch screen, achieving the control on an object in an approximate limitless range. When the user continuously draws circles on the touch screen in the rotary mode, the sliding speed and the sliding direction can be respectively calculated and judged by collecting sampling points on a reading device touch screen of the touch screen; based on the sliding speed and the sliding direction, the object elements can be continuously scrolled at different browsing speeds and in the positive and the negative directions; thereby the invention has the advantages of simple and flexible operation, fast browsing speed and space save, and is not restricted by the clockwise or the counter clockwise circle-drawing directions; moreover, the invention realizes the function that the object contents can be continuously scrolled in the positive direction and the negative direction in a relatively small touch screen without need of raising a pen by the user, thereby enhancing the applicability of hand-held reading devices; the invention can be widely applied to all touch screen reading device for searching different contents.

Description

technical field [0001] The invention belongs to the field of information technology, in particular to a touch-screen-based browsing and retrieval method with rotating continuously variable speed. 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. At the same time, due to the wide application of touch screens, various Various touch-screen reading devices, such as: e-books, electronic dictionaries, personal digital assistants, learning machine products and large-screen mobile phones, etc. The display screen of the above-mentioned touch-screen reading device is generally small, and it is often necessary to perform a page-turning operation for necessary retrieval and reading during use. As an important indicator of a touch-screen reading device, it is necessary to quickly and accurately retrieve the digital content s...

AI Technical Summary

Problems solved by technology

The main problem existing in the existing touch-screen reading device is: when performing the above-mentioned retrieval and browsing, the touch operation can only be performed according to the pull-up bar, pull-down bar, icon or certain track given on the display screen, and the corresponding content is displayed as The way of scrolling is displayed on the display screen, and it is still necessary to perform repeated operations of pressing and lifting for each operation until the desired content is retrieved. If the content is large, the operation is also complicated and time-consuming; in addition , if there is no pull-up bar or pull-down bar on some touch screens, the operation is more complicated, and the pull-up or pull-down function of the display screen content cannot be realized

Therefore, the prior art has not fundamentally solved the functions of the touch-screen reading device to quickly retrieve and display the reading content, and there are problems such as inconvenient operation and slow retrieval speed.
