I. Introduction Touch screen technology enables direct interaction with devices through touch. Using either capacitive or resistive methods, these screens detect user input, translating it into commands. Widely used in smartphones, tablets, and kiosks, touch screens offer intuitive navigation, eliminating the need for physical buttons and enhancing user experience across various applications. Understanding how touch screens work is crucial for users and developers alike. It enhances user experience by ensuring effective interaction, informs choices in device selection, and guides troubleshooting. For developers, knowledge of touch technology is vital for creating intuitive applications and improving interface design, ultimately leading to greater user satisfaction. This blog aims to explore why touch screens predominantly respond to fingers, delving into the science behind touch sensitivity. By examining the principles of capacitive and resistive technology, we will uncover the
What is industry 4.0? It is the fourth industrial revolution, where we focus more on the artificial intelligence. Industry 1.0 was the evolution of steam engine then in industry 2.0, electrical energy came in to picture and in industry 3.0 computerized automations were done. Now in the era of industry 4.0 we talk much about cloud computing, internet of things, virtual reality, augmented reality, artificial intelligence and autonomous robot. For an example, we are making 100 parts per day from a lathe machine. If we gather all the machining criteria in all the cycle and store the same in cloud, over a period we collect all the data and do analysis and find for a particular range of spindle speed defects are more. Then we can decide the same machining speed to minimize scrap. Also we can determine at what criteria machine health remains good or at what period of the shift, defects are more. Probably at the end of shift because of tidiness operator runs machine with increasing mac
