Portable device sensing control system and method

Abstract

The invention discloses a portable device sensing control system, which comprises a recording module, a judgment module, a comparison module and a control module, wherein the recording module is used for recording light quantity information in the starting of an interface and recording current light quantity information at the interval of preset time; the judgment module is used for judging the type of the currently started interface and judging whether a proximity sensor senses a shadow or not; the comparison module is used for judging whether the recorded current light quantity information is consistent with the light quantity information recorded in the starting of the interface, and calculating a difference value between the recorded current light quantity information and the light quantity information recorded in the starting of the interface if the recorded current light quantity information is inconsistent with the light quantity information recorded in the starting of the interface; and the control module is used for controlling the zooming in / out of the started interface or the upward and downward scrolling of a scrollbar according to the type of the started interface, the difference value between the current light quantity information and the light quantity information recorded in the starting of the interface and whether the proximity sensor is shadowed or not. The invention also provides a portable device sensing control method. By the system and the method, the zooming in / out of the interface of a portable device or the scrolling of the scrollbar can be conveniently controlled.

Description

technical field [0001] The present invention relates to a control system and method, in particular to a portable device induction control system and method. Background technique [0002] With the gradual development of technology, portable devices are becoming more and more popular and diversified. Such as PDA, smart phone or MP4 and so on. Most of the portable devices now use touch screens, and are also equipped with light sensor and proximity sensor components. [0003] There are many ways of zooming in and out of photos and pictures and sliding scroll bars on portable devices, and the recently popular way of zooming in and out of photos and pictures is to use two fingers (index finger and thumb) to move and move on the touch screen. Merging action; sliding the scroll bar method is to directly use the hand to slide up or down the screen to slide the scroll bar, and control the sliding speed of the scroll bar with the acceleration of the slide. This kind of physical cont...

Problems solved by technology

This kind of physical contact action is too frequent, which may easily cause scratches on the screen, or sometimes if the touch screen has not been calibrated for a long time, resulting in insufficient sensitivity, it will cause the portable device to misjudge and fail to execute correctly. operation
