Mobile terminal based touch track detecting method and system

Abstract

The invention discloses a touch track detection method and system based on a mobile terminal. The method includes: when a touch is detected, periodically acquire the touch point and calculate the sliding acceleration; judge whether the sliding acceleration satisfies a preset condition, if yes Then it is determined that the sliding track is valid, otherwise the sliding track is invalid. The method of the present invention obtains the touch points periodically and calculates the sliding acceleration when a touch is detected; judges whether the sliding acceleration satisfies the preset condition, if yes, the current sliding track is valid; otherwise, the current sliding track is invalid. It adds a new function of sliding acceleration calculation to the touch screen detection of mobile terminals, so as to achieve the following two purposes: 1) Avoid sliding operations that are not required by users caused by false touches during sliding operations on the touch screen; The detection of the acceleration of the sliding track makes the detection methods of the sliding operation more diversified.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a mobile terminal-based touch track detection method and system. Background technique [0002] At present, most of the input of mobile terminals is done by touch. Due to the large area of ​​the touch screen, it almost occupies the entire front of the mobile terminal. Therefore, accidental touches often occur in daily use. No matter how careful and cautious, it is inevitable to touch by mistake; [0003] On the other hand, the sliding operation through the touch screen is one of the most common touch operation methods. In the prior art, the sliding operation has no other distinguishing features except the direction of the sliding. Therefore, for the sliding operation of the touch screen, currently There is only an operation mode of sliding in one direction, such as sliding to the right and sliding to the left; therefore, the detection of the sliding operation is relatively s...
