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
I. Introduction Before the advent of modern technology, humans relied on natural cues for navigation. This included using the stars, the sun, and landmarks on land and sea to find their way. Navigational tools like astrolabes and sextants were also developed to measure celestial angles. In 19th century, the magnetic compass became widespread making it easier for sailors to maintain a consistent bearing. Nautical charts also improved, providing accurate depictions of coastlines and underwater features. Inertial navigation systems initially developed in mid20th century for military applications, which became important for aircraft and spacecraft. They relied on accelerometers and gyroscopes to track movement. The Global Positioning System (GPS) was launched in the late 20th century by the U.S. Department of Defense. GPS provided highly accurate global positioning through a network of satellites. It revolutionized navigation for both military and civilian use. With advancements in tec
