The ts_calibrate calibration touch screen provided by the ts_lib package is very simple and practical, but there are two problems in the xsever-based GUI application environment. 1. After calibration, you must restart X for the application to take effect. In this way, the user cannot accept it, because it
Part 1 Research Background
Background and challenge of interface design of 1.1 touch screen mobile phone
Challenge 1: Short development time, research at home and abroad are still in the exploratory stage, full of unknown and uncertain.
Touch screen technology was first applied to the mobile phone to date back to 19
1. Hardware principles
1.1 Overview
We often use two types of touch screens: resistive touch screen and capacitive touch screen. They differ greatly in hardware and are relatively less in driver implementation. The capacitive touch
Mobile Swipe Touch EventThe effect of mobile touch screen sliding effect on electronic devices has been applied more and more widely, similar to the PC-side picture carousel, but on mobile devices, to achieve this effect of the carousel, you need to use the core touch events. Handle
Many times, the use of touch screen fling, scroll, such as gesture (gesture) operation will make the user experience of the application greatly increased, such as using scroll gestures in the browser to roll the screen, with the Fling in the reader page and so on. In Android, gesture recognition is done through the Ges
feedback at all, and they can see some of the interactive feedback when they operate with their fingertips. Then, when users use equipment, switch fingertips and finger pads, no doubt reduce their operational efficiency.
Not only that, small touch targets can cause operational errors. When several small touch targets are closer to each other, the user accidentally touches a neighboring target
The effect of mobile touch screen sliding is actually the picture carousel, which is well implemented on the PC's page, binding the click and MouseOver events to complete. But on mobile devices, to achieve this kind of carousel effect, you need to use the core touch event. H
preceding steps, any sampling data is passed to the callback function defined by touchpanelenable. the driver can transmit calibrated coordinates or un-calibrated coordinates to the callback function. if the driver has an effective calibration algorithm, the calibrated coordinates can be returned. if the algorithm is complex, the UN-calibrated coordinates can be returned to avoid calculation in the high-pr
